It’s a Game of Averages

11 Sep , 2016  

– Tony Schaefer

Many times, when discussing hypermiling techniques, someone will ask about how to approach a hill, or what to do in rush-hour traffic, or when driving in bad weather can’t be avoided. The only sane answer is, “get over it.” Let’s face it: if you are going to scrutinize every single mile or every single minute, you will go insane. That is why hypermilers talk in terms of tank averages and lifetime averages.

Tank Average

This should be your smallest unit of measurement except for the rare exception. It is only over the course of an entire tank that you can take multiple factors into consideration: morning versus evening commutes, good weather versus storms, etc.

If you wish to maintain daily logs – and for various reasons, I have suggested just that – bundle them into the tank average and then throw them away. Daily logs are for analysis and review only. For example, another article suggests keeping daily logs for the sake of identifying the best daily commute. Once these logs have served their purpose, dispose of them.

The easiest way to calculate the tank average is to divide the miles driven by the amount of gasoline used to refill the tank. However, here are some factors to consider:

  • Some cars use bladders inside the gas tank to help contain vapors. Depending on the ambient temperature, the bladders might be more or less flexible in warmer and colder conditions, respectively.   For example, the second generation Prius used a gas bladder. In the summer, almost 10 gallons of gasoline could be pumped whereas in the winter as little as 8 gallons was the maximum. The Prius fuel bladder was removed starting in 2010. This is an issue because it adds a variable when attempting to accurately calculate the amount of gasoline used during the tank.
  • There is always the debate whether the on-board calculations provided by the car are accurate enough to be used. Some people choose to perform their own calculation rather than trusting the car. Anecdotally, some people have used both and shown that over a period of time, the over/under evens out and both methods arrive at the same Lifetime Average. However, for the individual tanks, which method you use is up to you.

Lifetime Average

Of course, the granddaddy of all averages is the overall Lifetime Average. This reflects your entire driving experience with the car. Lifetime averages do not need to start when the car is brand new; it is the one-number record of you and the car working together as a team, regardless of how old the car was when you two first met.

As you can imagine, calculating the lifetime average requires that you know exactly how many miles you have driven and exactly how much gasoline you have consumed. Not just for one tank or one month or even just one year. In order to calculate an accurate lifetime average, you must have been recording accurate fuel data for the entire time you have been driving the car. Trust me: this can get tedious but it is what must be done to achieve the goal.

12-Month Rolling Average

As you drive your car year-over-year, you might become curious whether you are becoming a better hypermiler. Actually, it’s great to constantly want that feedback to spur improvement. The problem is that the Tank Averages can’t be compared one-to-one and after a while the Lifetime Average barely budges.

This is where the 12-Month Rolling Average comes in. Whereas the Lifetime Average will forever be influenced by those first few crappy tanks, the Rolling Average will eventually let them go to reflect how you’re doing now. Though you can’t throw them out completely because they are part of your historical record, they are no longer an accurate representation of your current driving ability.

Calculating the 12-Month Rolling Average requires that you go back one year (sounds pretty obvious, doesn’t it?). Where it can get complicated is that the number of tanks will vary. For example, if you average a refill every other week, you cannot simply take the last 26 tanks and assume that’s a year. There will be those long-distance road trips in which you consumed a full tank in only two days. So just be careful and make sure to do the math based on the dates: sometimes 28 tanks, sometimes 32.

Conclusion

If you only keep two averages, they should be the Tank Average and the Lifetime Average. These give you a real-time feel for your hypermiling abilities and an overall view of your entire driving experience. Adding the 12-Month Rolling Average provides an updated perspective, showing how you’ve done over the past year.

Planning Trips

5 Sep , 2016  

– Tony Schaefer

In another post, we discussed how to best handle your day-to-day commute by finding a mileage-friendly route, memorizing it, and documenting how well you do. This article will address how to handle those unexpected and irregular trips. For example, running errands on the weekends.

Combine Trips

This should be obvious but I’m just throwing it out there.

Quite possibly, the silliest thing you could do is to make a bunch of little errand runs throughout the day. As long as you’re out running errands, hit all your stops in one go. Seriously, there’s not much more to write about this except to make note that the order in which you combine all your trips is important. So with that…

Go to the Farthest Destination First

It seems like the easiest and best thing: go to the closest destination and progress out until you’re at the farthest destination and then head home. However, in terms of mileage, this is the worst possible way to approach the situation. Here is the underlying reason: cars get better mileage once they are warmed up. If you string together a bunch of short drives, the engine will never have an adequate chance to properly warm up. It will always be running in an inefficient warm-up mode.

By starting with the farthest destination, the engine will have that initial chance to get completely up to temperature and start running efficiently. Then, when you head to the second stop, the engine is starting from a warm condition and is more likely to return to optimal temperature before stopping again. The same goes for all subsequent stops. The point here is that you want to give your car at least one long drive to reach optimal temperature.

As with all things, there are exceptions. The above advice works great for non-perishable errands (crafts store, hardware store, library, etc.) However, if the farthest destination is the grocery store with frozen food, you might want to plan the route so you get there last before heading home. If the farthest destination is a restaurant of the theater, you’re going to want to end there.

Consider Taking a Roundabout Route

If you are out running errands, then you’re probably pretty familiar with the area within about 5 miles of your house. With this in mind, you should have a pretty good understanding of traffic fluctuations in relation to a place, time, and day of the week.

When provided the opportunity, take a more roundabout route if it means dodging traffic situations and stoplights. Keeping clear of traffic situations could mean better constant-speed driving as will dodging the stoplights and stop signs.

Did you know that UPS drivers are routed in such a way as to minimize their number of left turns?

UPS engineers found that left-hand turns were a major drag on efficiency. Turning against traffic resulted in long waits in left-hand turn lanes that wasted time and fuel, and it also led to a disproportionate number of accidents. From 2004 to 2012, the right turn rule combined with other improvements saved around 10 million gallons of gas and reduced emissions by the equivalent of taking 5,300 cars of the road for a year.

Think about that. Not only does turning right mean that you spend less time waiting for traffic to clear, it means that you do not cross lanes of traffic as much. Turning right is much safer than turning left.

One consideration that might be a bit of a stretch is that the less-than-direct route might have better roads. In other words, find a path that avoids crappy roads. No doubt you have noticed that your car rolls better and gets better overall mileage on freshly paved, smooth roads. If provided the opportunity, define your route based on traveling on the smoothest roads. Besides, driving on rough roads just plain stinks.

All these things, when put together, might provide a more fuel-efficient route than heading directly to the destinations without any forethought.

Run your Errands when it’s Warm Outside

This concept works in combination with driving to the farthest destination first. Driving when it’s warmer outside will help your engine warm because the air rushing past the engine will be warmer. In some geologies, the morning-to-afternoon temperature swing can be several degrees. You need a sweater in the morning but have stripped down to a T-shirt by mid-afternoon.

If you like to get up and out as early as possible, that’s fine; just as long as you know that you might be taking a hit to your mileage. If you can wait a few hours, when the outside temperature is higher, you will be rewarded with better mileage. In the meantime, find other things you can do perhaps around the house or whatever.

Give Yourself Plenty of Time

This is a tried-and-true mainstay of hypermiling. When we feel rushed, we tend to make bad decisions, press a little harder on the pedal, and generally compromise the hard work we’ve done so far.

So here’s what you do: as long as you’re waiting for the temperature to go up, plan your trip so that you hit the farthest destination first. Once you’re done with that, figure out how long your entire trip will take and leave on time. So you see, a bunch of these concepts fit hand-in-hand.

Conclusion

Sometimes we have to make that one-off trip to the grocery store or hardware store or whatever. But when a series of errands require that you top at multiple destinations, taking a little time to plan it all out could reward you with improved overall mileage.

Document, Document, Document

25 Jul , 2016  

– Tony Schaefer

“That which is documented is measured.
That which is measured is improved.”

There are several attributes as to who originated that quote, whether it was ever actually spoken, or whether it’s a mash-up of multiple quotes. As important as is the origin, the impact it can have is equally so. Basically, it’s this: if you want to improve something, start documenting. However, documentation does not, in and of itself, result in improvement. That’s where the middle step comes in: the documentation must be measured and comparisons must be made. After all, sheets of detailed documentation would be meaningless if they were tucked into a binder and never reviewed.

What Do We Document?

The following is going to be a list of as many possible things as I can imagine. In no way am I saying that you must document it all or even that every item is important to you. It’s up to you, your priorities, and your gumption to decide how far you wish to take the whole thing.

Route Timing (with waypoints)

Sometimes, the speed of the drive is more important than the mileage. Or perhaps you’re interested in finding out exactly how much longer it takes to drive one route compared to another. Consider using a small notebook and a pencil to make note of when you pass certain intersections or other static waypoints.

Create a table on the sheet. Down the left, list all the waypoints. Along the top, list Mon, Tue, Wed, etc. or perhaps Day1, Day2, Day3. Whatever. The waypoints should be far enough to allow a measureable amount of time but close enough that the measurements aren’t a half-hour apart. For example, when I did this, my 50-minute commute had eight waypoints, mostly represented by stoplights, four-way stops, or important turns.

Some unexpected benefits to logging when you pass certain areas include knowing when the train comes, knowing the school bus routes, knowing when businesses let their employees out, etc. Sometimes it’s possible to identify something that had always been taken for granted but can be completely bypassed by adjusting your travel time.

The key to logging the travel is to be accurate to the time displayed on the clock in your car. From day to day, you might leave at approximately the same time but perhaps not exactly the same time. Don’t worry about that. Just record the time exactly as the clock shows it. After the trip, go back and figure out the time it took to travel each segment. Do not attempt to calculate the travel time until after the trip is complete. Driving is hard enough without performing math.

Don’t expect a good average for the segments until you’ve driven the same route for a full week. By that time, you will know very precisely exactly when you will be passing specific points in your drive based on when you started the drive.

Route Congestion versus Travel Time

If you have the liberty, consider driving your regular commute at different times to see how traffic patterns vary. We’re not talking about hours apart, here. But no doubt you’ve noticed that leaving home fifteen minutes later than usual results in completely different traffic characteristics.

Why would you do this? If you are going to be working on achieving good mileage, you might want to be surrounded by fewer cars. For example, it is harder to pulse and glide when you are creeping along in bumper-to-bumper congestion. On the other hand, you will have fewer opportunities to drive at the speed you want when the few cars on the road want to drive all-out as fast as possible.

The key is to find that time when there are enough cars on the road to keep everyone at a reasonable pace but not so many that it’s a parking lot. I’m not going to tell you that such a situation exists in your area, but it might and you might not know about it.

Trip MPG

The good news is that some newer cars display the trip mileage on their own. You simply need to write it down at the end of the drive. If you have an older hybrid, however, you might need to reset the trip odometer to get the mileage for just that trip. If you have a non-hybrid, you might not be able to calculate the trip MPG at all. I say that because – unless you have another way – the only way to manually measure consumption over distance is to start with a full tank and then top off the tank when the drive is over. Since we’re talking about single-trip calculations, the amount of fuel consumed will be miniscule.

Documenting the Trip MPG is nice, but by itself, only presents a part of the story. For example, yesterday your trip MPG was much higher than today. Why? Without other variables, it might be impossible to know. Which is why you might want to also consider documenting. . .

Trip Temperature

Anyone who has driven a hybrid for more than a couple years knows that the ambient temperature really does have an impact on mileage. On the surface, it is easy to see that when the temperature is lower, the mileage is also lower. However, a little digging will reveal that the engine block cools down faster in the cold air and ran more to keep warm; the battery was cold in the morning and wasn’t running as efficient; or perhaps you were cold and ran the heater. Likewise, a hot battery pack is not a happy battery pack and you are more inclined to run the A/C when the temperature is above 90F.

And so it is that with the combination of trip MPG and temperature, the mystery of why today’s mileage is different from yesterday’s might be settled with an examination of the role played by ambient temperature.

Tank MPG

Most hybrids and some newer conventional cars maintain an average MPG that the user can reset; many users reset it when they refill their gas tank. In this way, an average for the entire tank can be recorded. Another way to record the tank average is to divide the number of miles driven (per the odometer) by the amount of gasoline physically pumped into the tank. This can confirm the car’s calculations or prove it wrong. Some hybrid drivers have proven that even if the tank-to-tank calculations don’t match, they tend to even out over time. Which is to say, the car’s calculation and your manual calculation might differ for individual tanks but over multiple tanks, both methods return a very similar calculation.

Average Tank Temperature

This one is a little controversial. I didn’t think it would be, but clearly I was mistaken. When I recorded and posted my tank-to-tank averages, I would refer to weather.com for temperature readings. Here’s what I did: in a spreadsheet, enter all the high and low temperatures for each day during that particular tank; then average all the numbers. This is the value I entered as “average temperature for the tank.” Was I actually driving at the hottest or coldest points of the day, every day? No. What about the days I worked from home and didn’t actually drive; did I include those days in my calculations? Yes. Why? I simply didn’t care enough to be that precise. The end result was, as far as I was concerned, close enough.

How Do We Document?

This one is entirely up to you. File it under “try a lot of things and go with whichever one works best for you.

Personally, I record the tank averages. There is an added convenience to this: with every fill-up the gas station gives me a receipt. On that receipt is the exact amount of gasoline I pumped to which I add the car’s reported average MPG and the odometer’s recorded distance. The amount f gasoline simply adds into the “total amount of gasoline consumed”. The tank distance is primarily used to verify the overall odometer.

A friend keeps a small notepad and pencil in his glove box. He records all the pertinent information there. He never transfers the data and refers to the notepad when he wants to look up past tanks. Since I transfer my numbers into a spreadsheet, the gasoline receipt is temporary.

How Do We Use the Measurements?

Most people keep their documents because they simply want to know their own mileage. It surprises some people have quickly a problem can be detected simply by monitoring the mileage. For example, some people have been able to determine they get better mileage with one gas station versus another. Others have been able to identify a failing 12-volt battery through a drop in mileage. Of course, if a hybrid battery is starting to fail, overall mileage could be a forbearer.

My spreadsheet started simple but became more complicated in time. I started with:

  • Date
  • Tank MPG
  • Tank Miles
  • Refill Gallons
  • Tank Ave. Temp

With these four data points, I was able to create a historical trend graphic showing tanks over time compared to the average temperature for each tank. The “Tank Miles” was only because I wanted to know how many miles I could travel on a full tank of gas.

In time, I started getting curious about other calculations such as a rolling 12-month average and the Lifetime Average MPG. With the Lifetime MPG, I can use the sum of all Refill Gallons (Total Gallons) to compare my car to any other car driven the same total distance. By using their estimated MPG, it’s easy to show how much more they spend in total fuel costs.

Here is a screen capture showing one 12-month span from August 2010 to August 2011. This format shows the raw numbers and automatically generates the chart underneath. With the temperature shaded in the background, it is amazingly easy to see the direct impact temperature has on overall mileage.

Conclusion

Whatever your intentions, without proper documentation there cannot be proper measurement and nothing will improve. Think of it this way: if you want to tell someone you get good mileage or that you drive the quickest route, or that traffic is always bunched up this time of day, be prepared for them to say, “prove it.”

What Drives Us episode

2013 Ford Fusion Energi Plug-in Hybrid

4 Jun , 2016  

– Tony Schaefer

(Check out all our car review videos at our Youtube channel: Youtube.com/WhatDrivesUs and click “Playlists”)

Special Note: I drove the Ford Fusion Energi during a particularly cold December week in order to test its cold-weather performance. Taking exterior pictures in sub-freezing temperatures is not pleasurable. For that reason, there are not many personal pictures accompanying this article.

2013 Ford Fusion Energi

I have to admit I was really looking forward to driving this car. My wife owns a 2010 Fusion Hybrid and really likes it. I wanted to see this new generation of Fusion and experience how Ford has incorporated the plug-in technology. After all, this might be my wife’s next car.

Simply driving the car wasn’t enough. I wanted to test it. Hybrid drivers know their car will return the best mileage in warm months. Every plug-in manufacturer promotes the mileage earned by a fully charged vehicle. What I wanted to do was see how well the Fusion Energi would perform during a Chicago December being plugged in only sporadically. By capturing a snapshot of how the Energi performs during difficult situations, I hope to get a sense of how good it can be during the best of situations. Additionally, I hope to get the car again during the summer months for a true comparison.

Exterior

Fusion Energi GrillComing from the 2010 to the 2013 is a huge change in terms of the exterior. Parked side-by-side, you would have difficulty identifying them as versions of the same vehicle. Gone is the high-chrome grill and in its pace is the large open grill that has become Ford’s standard. I know there are many people who liken it to high-end luxury cars and they praise the aggressiveness. I’m not blind; I see it. It’s just not my cup of tea.

Having said that, the leading edge of all Fusion models does indeed take an aggressive stance. In darker colors, the combination of the grill and headlights presents a frowning, angry profile.

This front-end extends beyond he front wheels more than I anticipated. Couple this with the hood slanting down away from the driver and I had very little idea where the front of the car actually was at any point. Parking was a fun game of trying to pull into a spot without curbing out.

All-in-all, except for that front-end, I can’t help but to describe the Fusion styling as under-toned. Ford keeps with minor details and only a few accent lines. Ford has an established history with established models; there is little need for them to go out of their way to make their vehicles flashy and showy. They keep the Fusion clean and in doing so keep it classy in my opinion.

J17721Of course, the easiest way to identify the Fusion Energi is the plug port just forward of the driver’s door. From some angles, it’s easy to miss. This port is covered with a round door that swings open when pushed. It’s lined with an LED ring. When unplugged, there is nothing very interesting about it. When plugged in, however, the ring pulses and provides a visual indication of the battery’s state of charge by illuminating a growing portion of the ring until it’s fully charged/illuminated. That’s a nice touch and avoids the need to power up the car to check charge level.

Interior

2013 Ford Fusion Energi Titanium DashboardLike the previous hybrid iteration, the 2013 Fusion Energi dashboard has an analog speedometer flanked by two full-color LCD computer screens. This is, by far, one of my favorite features with the Fusion vehicles. Rather than dedicate space to single-purpose gauges, Ford has computerized the displays so you can decide which gauge to display. The car I drove was the SE model, not the highest-tier Titanium. For this reason, I feel that my displays and options were limited. At least I hope so because our 2010 Fusion Hybrid had better displays than the 2013 Energi I test drove.

The driver controls the display of the dashboard screens with arrows mounted on the steering wheel. There are two sets of arrow buttons: right thumb for the right side and left thumb for the left side. For the most part, using these buttons with your thumb is okay. Unfortunately, the [up] button is curved around the top of the steering wheel post making it almost physically impossible to easily push with your thumb without adjusting your grip on the steering wheel. Even once you get comfortable with the arrow buttons, changing the screens can be a navigational nightmare. After a while, I came to know where the screens were located in the maze of levels and sub-levels. It made me wonder whether you’re supposed to simply pick a screen and stick with it. Switching is certainly discouraged. I found the audio entertainment navigation on the right side much easier to navigate than the vehicle information displays.

2013 Ford Fusion Energi Steering WheelEasier to reach are the cruise control buttons on the left and phone controls, voice controls, and volume controls on the right. The greater scheme of the layout becomes apparent when you consider the left side of the dash is vehicle information and the left side of the steering wheel is car-related. The right side of the dash is infotainment and the right side of the steering wheel controls media. Once you get it, you get it.

The dashboard coloring is very easy on the eyes. Ford has employed shades of red and blue to create a nice, strain-free ambience. To offset the cool, relaxing hues, there is a “Ready” indicator, which lets the driver know the car is started and ready to be driven. If the overall dashboard can be described as relaxing, the “Ready” light, by comparison, can be described as “highlighter-green LED shone directly into your eye.” I can understand the need for a “Ready” light since powering on the car rarely includes starting the engine. However, once the car is shifted into Reverse or Drive, the “Ready” light becomes moot. Ford is not alone in the “Ready” indicator, of course, but it is the only car I’ve driven that left a blind spot on my retina.

2013 Ford Fusion Energi Capacitance ButtonsMy first impression of the overall cockpit and center console was underwhelming, but not in a bad way. The lines are clean and capacitance buttons replace most of the conventional air conditioning buttons and knobs. This means they use the electrical capacitance of your fingers to trigger the buttons. When you remove the push buttons and dials found in most cars, you are rewarded with a cockpit that is clean and sleek.

A word about capacitance buttons. These function on essentially the same principle as smart phones in that the small electrical current in your finger closes the circuit and activates the button. The idea of capacitance buttons in a vehicle was clearly conceived in warmer climates. One morning, it was 8°F. The car had been sitting outside all night. After knocking the fresh snow off the car all I wanted was warm air and heated seats. But what really warmed my heart was taking solace in the mental image of a Ford executive somewhere outside Dearborn, Michigan, being forced to remove his gloves – just like I had to – in order to use the buttons that heat his car.

And don’t even try to tell me about those gloves with the special fingertips so you can use your cell phone. I shouldn’t have to buy new gloves just to heat my car. I was 8°. A couple months later, it was -12° with a wind chill of -40° and I’m scraping ice off the windshield. That’s not special capacitance glove weather; that’s hockey glove weather.

Once engaged, the cabin heats quickly and efficiently. I base the heating of the cabin on a couple things: when I can remove my gloves (voluntarily) and when the engine will shut off. These factors tell me that the cabin is warm, the engine is warm, and the A/C is no longer drawing huge amounts of heat off the engine. In the Fusion Energi, I had reached both qualifications within about a mile and perhaps ten minutes. Granted, when you’re sitting in a cold car, this seems like a long time but it’s faster than other cars I’ve tested. Heated seats, as always, help.

I tend to adjust the dashboard illumination quite a bit based on natural lighting. I bump it up during the day and tone it down in the evening. Rather than a rheostatic wheel seen in other cars, the Fusion Energi uses up and down arrows to allow specific stepped adjustments. I personally prefer this; it just feels more precise.

In my wife’s 2010 Fusion Hybrid, the headlights do not automatically turn off when the car is powered off and locked. Rather, it reminds the driver to turn them off with a series of chimes. I normally admit when I am being petty but in this case, how hard is it for the car to know that it is parked and powered off? For the cost of the Fusion Energi, in the 21st century, headlights that turn themselves off should be standard.

The headlights controls themselves left me a little baffled. Employing a dash-mounted dial to the left of the steering wheel, I found it neither easy to see, reach, or understand. I am one of those drivers who uses the headlights as a communication method with other drivers. On one commute, I wanted to blink my lights to indicate that I would yield right-of-way to a car wishing to turn in front of me. This requires only a twist of the stalk in my current car; in the Fusion Energi I couldn’t figure it out and ended up snubbing the poor guy.

Under the center console, Ford has taken advantage of a dead spot by building in a storage cubby. Due to its height, location, and depth, I found it considerably easier to put things into this cubby than to fish them out again. One little gem was the cigarette lighter power plug which could be used as a phone charger.

In the center armrest console, Ford has fitted 2 USB ports, audio/video ports, a cigarette lighter power port, a pen holder(!), holder for business cards, and removable tray. Fortunately, Ford redesigned this area: it’s oddly oriented and nearly impossible to access the USB in the 2010 Fusion Hybrid; in the 2013, the ease of access is impressive. Topping it off is the cord minder and the ability to close the armrest without pinching the cords.

2013 Ford Fusion Energi Aux AudioI plugged my phone into the USB to see if it could access my playlists. Within a few seconds of plugging in, the active playlist started playing though the stereo system. This is as expected, of course, but some cars do not play well with Apple’s iOS 7. The phone quickly appeared as a media source on the central screen and all steering wheel controls were active. It started indexing my phone for the voice-activated commands.

I’ll finish my interior review with a feature I hadn’t seen in a while: individual driver presets. Once you find the seat position and side mirror combination that works for you, push and hold one of the buttons to program it. Up to three presets can be stored allowing multiple drivers to have the car return to their perfect settings the next time they get in. Or you could do what I did: program one of the buttons to move the seat to a position that makes it easier for you to get in and out.

Drivability

So many times people ask me about the differences of driving a hybrid versus a conventional car. No doubt a plug-in hybrid would make their heads spin. Rest assured, the accelerator is still on the right, the brake is still on the left, and the steering wheel still makes the car change direction.

One thing I noticed immediately was the amount of engine noise. I’m familiar with continuously variable transmission (CVT) systems generating high RPMs and sounding like they are working harder than they actually are. All that is not new to me. What surprised me was the volume at which the Fusion Energi engine came in and operated. Though it was hard to feel the transition from EV to engine, there was no mistaking the sound when the transition occurred. Case in point: I was near the front of a line of waiting cars being held by a construction flagman. When he waved for us to start moving, the Fusion Energi spun up and the flagman gave me a look as though I was intentionally revving the engine.

Engine noise aside, I did enjoy the overall drive. There were two separate snow storms during my time with the car. At no time did I feel concerned or unsafe. The Fusion handled very well in deep and falling snow. It was extremely capable in turns on slippery roads. My wife was not too pleased with the flashing traction control light on the dash, but that’s how you know it’s working. And work it did.

(OK, I admit that I was playing around and testing the traction control. Don’t tell my wife.)

The Fusion Energi has a push-button parking brake. It’s just a sign of the times, I know. But there’s just something about yanking that hand brake or stomping the foot brake that really lets you know it’s engaged. Pushing a button seemed too removed from the process. The same could be said for push-button start, I’m sure. No doubt we’ll see this in more and more cars in the near future.

The car I drove didn’t have a HomeLink button allowing the driver to program the garage door code into the car. Something like this eliminates the need for a separate and bulky garage door opener. As I said before, I didn’t have the top-of-the-line Fusion Energi but my wife has the top-end 2010 Fusion Hybrid and her car doesn’t have HomeLink either. Is this a Ford thing? Are they convinced people would rather have an ugly garage door opener hanging from their visor? Respectfully, I disagree.

Hybridability

As expected, getting excellent mileage in a plug-in while it’s running on electricity is easy. I don’t have the tech to calculate the amount of energy consumed to convert grid power to wheel power so I can’t speak to the MPGe. Some people might be a little disappointed in that; this makes it easier to identify the people who worry too much.

As I mentioned previously, I didn’t want to take advantage of fully recharging every night. I didn’t want to start each day with a full pack. What I wanted was to get an impression of how the Fusion Energi would perform for those people who only get to charge intermittently. To that end, I plugged in only two of the six nights. Also, it was Chicago in December. It was cold. I only parked in the garage on those nights I charged the batteries. Most mornings, the car was starting cold with a fully discharged battery in below-freezing temperatures.

First, I want to talk about charging. Ford uses what they call “My GO Time” scheduled charging. This is amazing! Not only can you schedule when to charge the batteries, you can tell the car to preheat the cabin to a preset temperature. Let’s discuss each of those components. There is ongoing debate whether it’s best to charge the car as soon as you get home or right before you drive it. Using “My GO Time”, the Fusion Energi will start charging when it needs to in order to be ready when you need it. Thus, it uses the ‘right before you need it’ philosophy. Also, preheating the cabin while the car is plugged in not only saves you from sitting in a cold car; it saves you from having to run the engine to generate heat. It’s part creature feature and part efficiency. One last thing about this: one morning I was running about ten minutes late. The heater was still engaged maintaining the designated temperature. I was in love.

2013 Ford Fusion Energi Included PlugThe Fusion Energi uses the standard J-1772 plug and comes with a 25-foot cord. I was concerned that it might not be long enough but it was fine. Even though the placement of my garage’s plug was nowhere near where the car’s plug port is, there was plenty of cord to spare. One point Ford stresses: Do Not Use An Extension Cord! This point is stressed repeatedly just about everywhere there’s a mention of plugging in the car. Just don’t do it. Most of the time, the car will be plugged in unsupervised; you won’t be there if the extension cord fails; you won’t know until your garage is burning down. Just don’t do it.

Driving the Fusion Energi, the car rolls surprisingly well. Why am I surprised? Because you can normally tell when a car is using regenerative braking or just capturing energy from spinning the wheels. There is usually a feeling of drag when you take your foot off the accelerator. The display screen indicated that regeneration was taking place, but I couldn’t tell which made me wonder just how much energy was being captured.

fusion_energi_EV_ButtonWhen I wanted to use the EV button, I found it awkward to reach. It’s located to the right and of the center-console shifter. In other words, exactly opposite the driver. It’s as though it’s hiding behind the shifter and my morning mug of coffee. Seriously, it’s inconvenient enough to be discouraged. I can understand that it’s not a good idea to overuse the EV button for multiple reasons, but this placement just felt like an afterthought. As though someone at the last minute realized they didn’t have a location for the EV button. Finally, someone said, let’s make it easier for the passenger to use than the driver. On the grand scheme of things, though, if this is what I’m complaining about, I’m just whining.

You might be wondering why I was reaching for the EV button so much anyway. Well, the Fusion Energi just didn’t seem to use EV Mode very aggressively on its own for my taste. I’m willing to conceded that this might be weather and temperature related, but I know my route and I know where a hybrid should be able to shut off the engine. Including my wife’s 2010 Fusion Hybrid. After a couple days, I realized the Energi just wasn’t going to shut it off so I took matters into my own hands. This is where I want to drive this car again in the summer to see if the lack of EV was indeed temperature related along with my desire to heat the cabin.

The gauges I used the most were the ones that showed the amount of demand I was placing on the car versus the amount of demand it could support before disengaging EV mode. Using this gauge, I could adjust pedal pressure to stay in EV mode as long as possible to minimize the use of the gasoline engine. The same gauge provided real-time MPG results. In a nice touch, Ford has the battery charge level nestled up next to the gas level in an unassuming manner. Simple arrows point up when charge is being added to the battery and down when charge is consumed. I’m guessing the average driver isn’t going to dwell on the battery state of charge as much as I do and this minimalistic approach provides information without over-exaggerating its importance.

2013 Ford Fusion Energi Dash - Collage

These displays are easy to read and very informative. I feel as though they provided the right blend of information for me to really work the car for maximum mileage. Speaking of which, let’s look at the numbers.

I’m going to be throwing around mileage numbers so keep in mind that the 2013 Fusion Energi is rated at 44mpg city and 41mpg highway for a combined 43mpg.

The average temperature on my morning commutes was about 16.5°. I did not shy away from using the heater and the heated seats. On the mornings when I started with a fully-charged pack, I achieved 180.2 mpg at 14° and 81.5 mpg at 8°. The difference between the two drives was the route: one is slightly longer but more conducive to hypermiling; the other is highway almost the whole way. On the mornings when the car sat outside and started with a dead plug-in battery, I averaged 38.4 mpg. Considering the circumstances, I consider this a commendable mileage number representing manageable drop in mileage. Shoot, I know Prius owners who see sub-40 mpg in the winter.

Ford claims the Fusion Energi should be able to travel up to 21 miles on a fully-charged pack. Perhaps it was the temperature, but the farthest I was able to travel on plug-in charge was 14.4 miles. I expected a hit to the range; it’s very well documented that every battery pack loses performance in cold temps. But from 21 miles to 14 miles is a 33% drop. That’s rather significant, in my opinion.

The evening commutes were usually warmer than the mornings though twice it was snowing and one evening I was hurried. Because my morning commute is far enough to completely drain the plug-in charge, my evening commute was always just as a normal hybrid. Five commutes, averaging 15.5°, gave me an average 38.3 mpg. This is just slightly less than my morning commutes but due to terrain, I see this in my own car and am not surprised.

For the entire week, my average mpg was 42.2, elevated by those two days when I fully charged. Let’s pretend I charged every night and averaged 130 mpg every morning (the average of 180 and 81). Perhaps I could expect to see close to 170 mpg. This should be above 200 mpg in the summer months. I shouldn’t have to tell you how excited I would be to see those numbers.

Familability

The Fusion, in my opinion, is a really good family sedan. I’m not just talking about the Energi; I’m talking about the Fusion in general. Ford has had many years to get the dimensions correct and, as far as I’m concerned, they’ve done a good job.

You can easily fit a family of four; each person gets their own cup holder. There are two in the front and two in the back. All are located in the center of their respective rows making for easy reach for all. Additionally, each of the four doors has a bottle holder built in. The placement of the cup and bottle holders keeps them within reach but also out of the way.

It seemed to me as though the back seats were just a bit stiff. It would be fine for hauling some coworkers to lunch, but as a kid I wouldn’t want to sit back there for a long drive. I drive to my folk’s home a few times a year: 375 miles each way. The kids are only as well mannered as their butts are comfortable.

The general slant of the back half of the roof seems to encroach on headroom in the back. I’m 5’9” and my hair was lightly brushing against the ceiling.

And then there’s the trunk. Let’s put it this way: the trunk comes preloaded with a 7.6 kW battery. That’s my best effort at putting a positive spin on it. Seriously though, it’s a plug-in hybrid. The battery has to go somewhere. Every plug-in hybrid makes the same – or similar – trade-off. There’s no getting around it. The Fusion Energi is no different. So, in my opinion, to complain about the battery encroaching into the trunk is just silly. If it bothers you that much, just buy the Fusion Hybrid.

Bags in the Trunk - 500I found that the trunk has room for five paper shopping bags. Maybe six if you cram. It measures 39” wide, only 13” deep, and 20” tall. Officially, the trunk is around 8 cubic feet. This is about half that of the regular Fusion. If trunk space is your biggest concern, due to kids activities, golf outings, tailgating, etc., then you might not have much luck here. The battery shape makes for some interesting trunk dimensions including a “shelf” on top of the battery that is 7” tall and 18” deep.

The 12-volt battery is located in a cubby just to the side of the trunk. I’ve seen this in other cars and assumed there’s a jump point under the hood. If this is new to you, it simply means there is a terminal under the hood that you can use with jumper cables and it’s as though you were connected to the 12v directly. Unfortunately, I couldn’t find the button or lever to pop the hood so I never found out. Seriously. I searched for several minutes in all the expected places then I searched in oddball places. Then I looked for the manual in the glove box but there wasn’t one.

Overall Conclusion

There is no denying that I honestly enjoyed driving the Fusion Energi. It seems to have an easy grace and comfort level that is difficult to explain. The exterior is well designed but also seems understated. With such an established line, the Fusion doesn’t really have to try very hard to be taken seriously in the marketplace.

The layout of the dash is very well thought out. The placement of the displays clearly follows a well thought out, logical design approach. This makes it easy to find what you’re looking for without taking your eyes off the road to search for it. The red and blue hues of the displays are easy on the eyes. My only critiques can be on the placement of some buttons and switches. No doubt, once you get accustomed to them it’s no longer a problem.

My cold-weather testing revealed that the Fusion Energi is capable of pretty good mileage even in relatively difficult situations. Without plugging in and charging the batteries, I achieved a respectable mileage of 38.4 mpg. This is what my wife averages in her 2010 Fusion Hybrid in good weather. I’m anxious to see how the Fusion performs in the summer. I predict I could come close to 50 mpg with minimal effort. But, of course, the power of the plug-in is the 21 miles of EV, which should stretch your gas money substantially. Depending on your situation, 21 miles might get you through a whole day.

Fitting a family of four into the Fusion Energi is a snap. The kids will be comfortable in the back except, perhaps, on long trips where I feel the seats might be a bit too stiff. Taller back seat occupants might get claustrophobic when their heads hit the ceiling. Half of the trunk is dedicated to housing the plug-in battery, which severely limits the amount of stuff you can fit back there.

Let’s say you have a minivan or some other vehicle for long road trips and hauling the kids’ soccer gear and whatnot. The Fusion Energi is a very nice and comfortable daily commuter car. Using “My GO Time” you can start every morning with a full battery and a conditioned cabin. With 21 miles of EV and decent pure hybrid mileage, my conclusion is simple: there’s a very high probability this will be my wife’s next car.

Know Your Route

28 May , 2016  

-Tony Schaefer

So many times, when it comes to achieving higher mileage, people focus on their car and how they drive. Most times, they just assume the commute is an unavoidable variable. A predefined route that some days has good traffic while other days has bad traffic. This article will explain why the route you take and how you drive it plays as much a role as all other variables. When it comes to improving, never consider anything to be predetermined. The goal is to scrutinize everything.

Find a Mileage Friendly Route

If you happen to live in a large city, there’s a very good chance there are multiple options when it comes to the daily commute. Personally, I have three choices that I will call “Fastest”, “Easiest”, and “Hypermiling”.

“Fastest”: I have the opportunity to hop on an interstate for about ¾ of my commute. Doing so would save about ten minutes and is an attractive option when time matters. The downside is that the interstate maintains a relatively constant 70 – 80 MPH except when it comes to a screeching halt for no particular reason before slamming back up to 70 MPH. In other words, exactly the opposite of hypermiling.

“Easiest”: There is a state highway that runs is literally a straight shot from town to town. Albeit, one with multiple stoplights. Like the interstate, traffic is either racing along (though closer to 50 MPH), stopping for the red light, or accelerating Grand Prix style at the green light. It’s a multi-lane stop-and-go early-morning ball of stress. In no way do I look forward to starting or ending my day on this drive.

“Hypermiling”: This drive is 5 miles and 9 minutes (on average) longer than the “Easiest” route. This drive has longer stretches without stoplights and some stoplights are timed. It passes two schools and one nature preserve. The highest speed limit sign is 45 MPH. It is on this route that I see joggers, walkers, and the occasional wildlife. On nice days, I drive this route with my windows down enjoying the sights and sounds. All the while, the speed is conducive to attentive hypermiling and plays into the capabilities of my car.

By selecting a different route, I can not only achieve better mileage, I can choose how my day starts and ends. If you find that you arrive at work already stressed and you return home mentally ragged, do yourself a favor and seek out a more casual and hypermile-friendly route.

Memorize Your Route

Here is an analogy parents can appreciate. Let’s say your son goes to the first day of school and is presented with a difficult, lengthy exam. How would you expect him to score on that exam? Probably not very good. On the second day, he is presented with the exact same exam. Should he do better than the day before? Perhaps. Let’s pretend your son is presented with the exact same exam every day for the entire 180-day school year. You would expect him to be acing that exam with absolutely no effort, wouldn’t you?

Now what about people working an average 250 days per year? Most of them drive the exact same route every day, to AND from work. Even after all this repetition, it has been my experience that people drive their daily commutes as though it’s their very first time. Every time.

You are a human (I hope). You are preprogrammed to identify and memorize patterns. It’s what we do.

  • Does your commute have a string of fast food joints all next to each other? If so, every evening there’s a strong chance a hungry driver will stop and turn without signaling. Expect it.
  • Do you cross railroad tracks? Make a mental note of when the commuter train comes through. Don’t forget to consider school busses stopping at the tracks during the school year.
  • Timed stoplights? If you didn’t make it from one light to another yesterday, or last week, or last year then you’re not going to make it today. Stop accelerating full-bore as though you have a chance. On the other side of that coin, memorize the speed at which the light will change from red to green as you approach.
  • I have a round-about. I know exactly at what speed I can make that round-about without braking (on a clear day and dry pavement). Coupling this with how far back I let up on the accelerator allows me to coast to the round-about, pray for no cars, and roll through without once touching my brakes.

If you drive a hybrid, consider basing battery usage on drive segments. Pick up some charge during the fast segments in order to run farther on battery during the slow segments. Or vice versa: consider going deep into the battery pack if you know an upcoming faster segment will allow you to recharge. Recharging will impact the instantaneous mileage. Ignore that; it’s the average that matters.

It’s all about driving the same route every day, figuring out what works best, and repeating it.

Summary

If you have the opportunity, drive a route that returns the highest mileage. If it turns out to also be least stressful, then it’s a double-win. The only way to know which route is the most fuel-efficient is to document each pass in order to develop an average and recognize patterns. Once the best route is identified, memorize how to handle each segment with the intent of getting better with each day.
