Although it could be one of the ugliest car hacks I’ve ever seen, Mike Turner of Hodges, SC, modified his 1992 Honda Civic to get 70 MPG.

As you can see in the picture and video clip, the modifications are relatively simple use of aluminum siding and plastic, which decrease wind resistance (vaguely reminding me of Aptera’s Typ1 electric car) and lowering the vehicle’s drag coefficient. It’s a much more extreme version of the modification seen on Ernie Rogers’ 76 MPG VW Beetle. Read the rest of this entry »

There’s been a lot of buzz on the internet and on TV about ecodriving, hypermiling, ecomodding, or  other techniques for saving fuel. EcoModder.com, a site dedicated to modifying cars and driving habits for fuel economy, recently released a list of 100+ hypermiling tips.

These tips are definitely worth a look for anyone interested in saving a few dollars at the pump, but before diving in, you should take a few cautions. This list seems pretty exhaustive, but that doesn’t mean you need to do every single thing. Practicing more techniques will save more gas, but they’re not all appropriate to every driver, car, or situation, so exercise this advice with care.

Does anyone do any of these things already? I wouldn’t call myself a hardcore EcoDriver, but I definitely practice quite a few.

VW’s Jetta BlueTDI: 60 MPG, 90% Emissions Reduction for NOx

VW’s ultra-low emission 2009 Jetta will be coming to the US mid-summer, according to an announcement made late last month at the Vienna Motor Symposium.

This newer version of the Jetta will meet the strictest emissions standards in the world—BIN5/LEV2—which are enforced by 5 US states: California, Massachusetts, Maine, New York, and Vermont. BIN5/LEV2 standards severely cap nitrogen oxide (NOx) emissions (0.05 g/mile), one of the two tailpipe pollutants that have given diesels a bad rap (that and particulate matter).

There’s been talk about the VW 1L concept for years. Since VW built the original, fuel economy, safety, price, and release date has been speculated upon and argued about, and I’d finally stopped thinking it was ever going to happen. However, according to VW’s CEO, it should hit the market in 2010.

The VW 1L is so named because, in theory, it only consumes one liter of fuel per 100 kilometers traveled. For those of us in the US, this translates into about 235 MPG. Definitely far and above anything on the market currently. The concept, developed in 2002, actually got better fuel economy, scoring a sweet .89L/100km in VW testing. It’s likely to use more fuel in real world use, but with that kind of mileage in testing it’s unlikely that anyone would complain about an “unsatisfactory 200 MPG.”

As has happened before, with gas prices continuing to climb, the demand for improved fuel economy will increase as well, and all manner of improvements and upgrades that promise to help get better mileage will be touted. Some offer real benefits; others are pure snake oil.

An improvement that offers both improved mileage and increased horsepower seems counterintuitive at first. After all, the tradeoff that hybrids and other economy vehicles offer seem to be one of reduced horsepower and acceleration in exchange for improved fuel economy. So how can you have both?

As the automakers scramble to make plans for achieving 35 MPG by 2020, it seems that our suspicions that the task is entirely possible without fancy hybrids or hydrogen cars has been confirmed. The manufacturers been achieving high mileage in Europe and Japan for years now, so I expect to see it in the US eventually. Luckily, there are six exciting new technologies that are going to make it possible in the US.

These technologies are interesting because they come without the paradigm shift that seems to accompany buying a hybrid or a small economy car. Cars equipped with this green tech will be just like any other car, just more efficient.

More on the six new engine technologies after the break.

The White House has outlined their plan to increase fuel efficiency standards to 35 MPG by 2020, a move that will save Americans an estimated $100 billion in fuel costs.

The mandate was outlined in last year’s energy bill in December, but this proposal gives a boost to the timeline by requiring the mileage of passenger vehicles to average 31.6 MPG by 2015. That’s up from today’s average of 25 MPG (which I can’t help but mentioning is identical to the mileage of the original Model T Ford). Read the rest of this entry »

How much gas money would you save if you didn’t have to make a lot of left turns?

UPS, the delivery people, decided to re-structure the delivery routes taken by drivers to eliminate as many left turns as possible. Now that may sound weird, but how long have you sat in a left turn lane waiting for oncoming traffic to pass, and how many times have you dreaded crossing into oncoming traffic?

The results have been dramatic. UPS says its 95,000 vehicles shaved nearly 30 million miles off its deliveries in 2007, saving the cost of 3 million gallons of gasoline and reducing truck emissions by 32,000 metric tons.

Makes sense to me. Sally and I both plan our drives with right-hand turns in mind, rarely adding an inch to the overall length of the drive, and feeling a lot safer.

Recently Darin at EcoModder dug up a Car and Driver article from the middle of the US gas crisis in 1974. It may be a little dated, but considering recent gas price increases these kinds of DIY hacks are becoming relevant once again.

The material prices may be a little different, the cars may be a lot different, but surprisingly little has changed in terms of fuel economy and gas prices. The Car and Driver article is interesting because not only is it old, but it’s still relevant today.

As someone who has been around ecomodding for a while, I can vouch for the efficacy of many of these modifications, and have done some of them myself. So, if you’re really interested, I encourage you to get out there and do some yourself. None of them are engine modifications, or particularly difficult, so don’t feel intimidated by them. Some of the biggest fuel economy gains can come through aerodynamics and rolling resistance modifications.

Read about the modifications after the break.

This is what a team of engineers can do when challenged to push the limits of fuel efficiency and technology. You may have already heard of VW’s 1-liter car, but take a closer look. It’s a sports-economy concept car produced a few years ago by VW engineers, to answer one big question: could they build a car that consumes less than 3 liters of fuel for every 100 km traveled?

It turns out they could, but they didn’t stop there. Instead, VW blew by that goal to create a car that uses only 1 liter of fuel for every 100 km. That’s 285 MPG.
