It’s a Game of Averages

11 Sep , 2016  

I’m in the process of recording these articles in a series of videos.  Click the image to the left to watch them.  While there, be sure to subscribe to the channel.


-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.

Hypermiling in the Social Media Age

28 Aug , 2016  

I’m in the process of recording these articles in a series of videos.  Click the image to the left to watch them.  While there, be sure to subscribe to the channel.


-Tony Schaefer

A lot of people are seemingly (or actually) addicted to Facebook, Twitter, SnapChat, InstaGram, and/or whatever new social media app / website just went online while I was writing this sentence. So much time is spent (some would say ‘wasted’) electronically interacting with people, the whole concept of social media has gotten a really bad reputation. However, it can be argued that there are  beneficial facets to social media interactions and the ability to instantly engage with multiple people regardless of time and distance.

This article will discuss ways in which you can use social media and internet communities to improve your fuel economy. When possible, links are provided to online sources; this is not a promotion of one site over another. If one of your favorite online resources is missing, let us know so we can include it.

Join a Hybrid / Car / Hypermiling Community

Have you ever heard of those car clubs or motorcycle clubs who just get together once and a while to talk about their cars or motorcycles. All they do is get together, hang out, talk car, and perhaps drive around. Sounds really silly, doesn’t it? Well, congratulations: now you can do all those things online!!

Thanks to Google, online car forums are really easy to find. In the forums, you can find information about driving techniques, how to perform regular (or not-so-regular) maintenance, or speculation about upcoming models and features. Some forums are broad in their scope while others are relatively granular. But they all have one thing in common: they are all sustained by a group of individuals with mostly the same interests and concerns as you. Because of that, it is usually pretty easy to be welcomed into the community and easy to form friendships with other forum members.

Here is a list of some online forums and communities. This is clearly just a partial list:

Send us links for your favorite online community or any other community you know of.

Create / Join a Fuel Consumption Challenge

A few years ago, a couple coworkers were curious about this whole hypermiling thing. The best way to get them personally invested was to set up a competition between them. Using a relatively simple spreadsheet, we used their car’s EPA numbers to gauge how their MPG improved by implementing some basic hypermiling techniques. The entire thing was based on the honor system so there’s really no way to vouch for its accuracy, but according to their self-reporting, each were able to achieve more than 10% above their EPA ratings. It’s hard to say whether they would have achieved these results had they not been competing.

When you know your results are going to be seen by others, you will try harder. This is why a little friendly competition might give you the push to kick your efforts up a notch or two. It’s not only competition that provides the incentive to improve; sometimes simply knowing others are watching is enough.

If you join one of the online communities mentioned above, see if they have a place where people can post their fuel economy averages. Many do. If you are using a spreadsheet to monitor your mileage, consider making it available online via Google Docs, DropBox, or any other online storage service. If that’s not possible, consider creating an account at Fuelly where you can enter your tank-by-tank averages. Then you can distribute the hyperlink to your Fuelly account.

Participate in Ride Sharing Programs

While this might not improve your individual fuel economy, it will reduce your overall fuel consumption.

Check around to see if there are any local web resources where neighbors can set up a ride-sharing program. You know, a good old-fashioned carpool. For example, check out NextDoor.com to find neighbors and start a chat. Find out if anyone works near you.   The best-case scenario would be if someone lives and works near you.

If you like your coworkers, at least a few of them, find out if they live near you or between you and your job. Some days, you can pick them up; other days you can park at their place and they drive. Either way, that leg of the trip is done with one car rather than two. Word to the wise: you have to really like that person because if it gets to the point that you can no longer stand riding them or if one of you gets a promotion and now it’s awkward, you will need to cancel the carpool. Of course, you’ll still see that person at work every day.

Use Waze

Waze is a free, real-time traffic service owned by Google (or Alphabet, whatever). It is primarily used via the phone app. As people drive, Waze uses geotracking to monitor their speed to provide everyone else real-time traffic information. Drivers can also manually provide information to the system such as backed-up traffic, a traffic accident, car stopped on the road, or even where the police are hiding today.

Once the user enters their destination, Waze evaluates all its information to determine the fastest and most trouble-free route. Unfortunately, Waze cannot apply hypermiling logic to calculate the most fuel-efficient route. But by directing you around stopped traffic, the amount of time you spend idling is greatly reduced. This will save gasoline and/or battery charge.

One note about Waze: you are providing your real-time location to the Waze application. As the adage goes: if the product is free then you are the product. If this makes you a little uneasy, just skip this suggestion.

Attend Driving Clinics or Seek Help from a Hypermiling Expert

In addition to the first suggestion promoting online communities, you might want to also look into local, real life groups. As a side note, it’s funny how we now have to distinguish things as being in real life (IRL).

These groups are usually formed and populated by like-minded people. Some of the events I’ve attended have been held in parks, parking lots, even car dealerships. In some states, it’s not legal to sell cars on Sunday but it is legal to have the service center open. This means a friendly dealership might welcome a group for a meeting.

At these meetings, technical car reviews might be provided, maintenance information, and tips from other drivers. It’s usually pretty easy to find someone who is achieving really good gas mileage and who is more than willing to talk with you about improving yours. Many of the meetings I’ve attended have include “ride alongs” in which the ‘expert’ hypermiler will ride with the learner, providing advice for improvement. I’ve performed several ride-alongs; trust me: people are happy to do it. Just ask.

Search your local area for car groups. Here are two groups on MeetUp.com that might help get you started:

Conclusion

In this day and age, it should be easy to find like-minded people which whom you can discuss fuel efficiency. Whether online or in real life, working with others – and maybe even competing – will certainly give you that extra boost to improve your overall mileage.

Pulse and Glide

17 Jul , 2016  

I’m in the process of recording these articles in a series of videos.  Click the image to the left to watch them.  While there, be sure to subscribe to the channel.


-Tony Schaefer

In this post, I will attempt to provide a simplistic overview of a hypermiling technique known as “Pulse and Glide” (P&G). Before we get started, you need to know that the application and technique for P&G is variable based on many factors such as the car, terrain, traffic, current speed limit, etc. For all those reasons, this will be an overview and not overly detailed. My concern is that if I provided any real details: 1) you would try to apply the details where they don’t fit, and 2) someone will argue the minutia of the details.

How Do You Pulse and Glide?

Many times, I compare hypermiling to riding a bicycle. This works because almost everyone knows how to ride a bike, which makes it a universal reference. Also, you most likely remember how tired you can become if you do not ride efficiently. Though neither you nor your car will get tired, you have to focus on the amount of effort being exerted; the goal is to travel farther with less effort.

The Pulse. Just like riding a bike, the intent of the pulse is to get up to speed. When accelerating from a dead stop, use a brisk acceleration: accelerate quickly but not stomp on the gas. Once you have reached a speed that is, perhaps, a little faster than the speed limit or average traffic speed, let up on the accelerator.

The Glide. Think about riding that bike. Once you have reached a decent speed, it requires only a minimal amount of effort to maintain it. In fact, depending on the situation, you might be able to coast for a long distance before needing to pedal again. In exactly the same way, the point of the glide is to “stop pedaling”.

The first and second generation Prius were exceptionally good at gliding because they had a “dead band”. This dead band is a spot in which there would be no power coming from the engine or batteries to drive the wheels and also no regeneration from the wheels to the batteries. A practiced driver could work the accelerator into that dead band and let the car roll.

Unfortunately, this type of “free wheeling” is nearly impossible in almost all modern hybrids. And so it is with modern hybrids that the glide is an attempt to reduce the energy flow to a point as low as possible.

Pulse Again. As you can imagine, after coasting for a while, you will start to slow down. Once you’ve slowed to a speed you are no longer comfortable with, pulse again. Unlike the dead-stop pulse, this time you want to use just enough acceleration to get back up to speed. Just like riding that bike, it’s not a sprint back up to speed but rather just enough.

And then you glide again. Then pulse, then glide, repeat.

Why Does it Work?

The concept is simple: the entire intent of P&G is to glide more than you pulse. The following image provides a sort-of representation starting from a dead stop, accelerating up slightly above the desired speed, gliding, pulsing, and then gliding again. As you can imagine, the farther you can glide the better. The black line in the following image might represent the average traffic flow, the speed limit, or simply the speed you want to average. Your situations will vary.

Pulse and Glide Image

It works because gliding is essentially free. It’s the pulsing that costs you. Therefore, rather than paying to constantly maintain a steady speed, you allow your speed to vary. The trick comes in making sure the pulsing uses less effort than would otherwise be used maintaining a steady speed.

Situational Considerations

  • As with all hypermiling techniques, obey all posted traffic signs and do not impede the flow of traffic for your selfish desires.
  • If you have rolling hills, that is awesome. Pulse up the hill and glide down the other side. They key is being able to gauge the most efficient time to transition from pulse to glide and vice versa.
  • One hypermiler told the funny story of being pulled over because the policemen observed he was “incapable of maintaining a steady speed” and assumed he was drunk. I didn’t say it was funny for him. He said that once he explained what he was doing, the policemen didn’t bother writing a ticket.
  • If you see a stoplight up ahead, consider modifying your pulse and glide timings to either glide into the stop or pulse a little faster to ensure catching the green light.
