Gas 2.0

We all know that fast cars are fun and fuel-sipping cars are environmentally responsible, but is there a middle ground?

Short of expensive electric sports cars like the Tesla Roadster, there may be a solution to be found in diesel. Not only can diesel cars be fueled with waste vegetable oil, biodiesel, or some mixture of these fuels, but diesel engines produce a lot of torque and get better fuel economy than their gasoline-powered brethren.

Update: VW announced this car will not be built because it was deemed “too expensive.” Sorry Folks, VW Diesel Electric Hybrid Not Coming to US.

Toyota may lose its high-mileage stranglehold on the U.S. auto industry, thanks to Volkswagen’s new Golf hybrid-electric diesel. At 69.9 MPG, the new model is a serious contender for high-mileage biodiesel usage with a ridiculously low-emissions profile, especially since it will meet the strictest emissions standards in the world: Europe’s Euro V and America’s Tier II Bin 5.

This makes it likely to be released in California, since the major impediment to U.S. diesel vehicle sales has been emissions technology. But VW doesn’t plan on releasing the vehicle in until Europe late next year, which means we’d optimistically see a U.S. version sometime in 2010.

Think you need a hybrid to get great mileage? Try a souped-down 1959 Opel T-1.

In another tribute to high-mileage car hacks, a man named Evan McMullen rediscovered a 1975 Guiness-World Record-Setting car that got 376.59 MPG.

It was wasting away in a museum in Florida:

That number doesn’t come from some manta ray-shaped, wind tunnel-vetted carbon fiber space car. No, it’s from a chop-top, steel-frame 1959 Opel T-1 (think melting jelly bean, but uglier). And the record was set in 1973 in a contest sponsored by Shell Oil Co.

Unfortunately, that contest-winning mileage number occurred on a closed track at a steady 30 mph. Not exactly highway speeds. Nonetheless, it makes you wonder about the evolution of automobile manufacturing in the last 50 years:

Imagine if you could eke more mileage out of your Prius. If you’re like me, you’ve already tried. What if you could get a decadent 100mpg? More? A group of Prius owners in Japan are doing just that - by hacking their Priuses.

According to this CNN report, the record holder among an underground group called “Mileage Maniacs” (Japanese language only) has managed to travel 1500 miles on a single tank of gas. That’s about 116mpg; I’m green with envy! Fortunately there is a similar push in the USA and Canada to feed the demand for more efficient cars. Numerous easter eggs , and hacks are available so an enterprising Prius owner can get more mileage. There’s even a solar company and those who will modify your car into an hybrid plug-in. Some plug-ins are already on the road. Voided warranty aside, extensive green modifications require a lot of green from the owner, ranging from a $40 kit to thousands of dollars.

Run your car on compressed air? Drivers in Europe may be doing just that by the end of the year, according to a report from the BBC…

Like to know more about the air car? Here’s their website.

Since last year, many of us have been eagerly awaiting the introduction of ‘clean-diesels’: the 2008-2009 models touted as having superior mileage and cleaner emissions than comparable gas models.

So where are they? Strangely, promised 2008 models didn’t materialize, and I had trouble finding more on the story. As far as I can tell, we’ll just have to look forward to next summer’s release of the 2009 VW Jetta TDI. The new Jetta gets similar mileage to older models, 50 mpg ( though VW engineers claim 30% better mileage under real world conditions). More importantly though, it’s the first diesel to meet the world’s toughest emissions standards, California’s Tier II, bin 5, earning it clean-diesel status. If you noticed the recent lack of diesel vehicles for sale (especially in CA), it was the direct result of reengineering emissions systems:

Although it won’t be wearing the “BlueTec” badge, the Jetta will be using emission-cleansing technologies developed under the cooperative formed by Audi, Mercedes-Benz and Volkswagen to make it 50-state legal. Most BlueTec vehicles control NOx emissions—one of the biggest environmental hurdles facing diesels, along with particulate matter—by injecting a urea-based solution into the exhaust system upstream from the catalytic converter, where NOx is then converted into nitrogen and water. The Jetta will instead use a NOx-storage catalyst, which is basically a reservoir that temporarily holds the noxious emissions, like a particulate filter, until they can be burned off during one of the engine cycles.

If you haven’ heard of the Motorhead Messiah, Jonathan Goodwin, let me introduce you: he hacks cars for a living, and he can get 60 mpg out of an H3 Hummer while doubling the horsepower and cutting emissions in half. Unbelievable? Yes, but this is no joke, and it’s doesn’t defy the laws of physics either. The hacked H3 is a hybrid with the gasoline fuel system removed. In its place, Goodwin installed a biodiesel-burning jet turbine to recharge the electrical system:

Goodwin leads me over to a red 2005 H3 Hummer that’s up on jacks, its mechanicals removed. He aims to use the turbine to turn the Hummer into a tricked-out electric hybrid. Like most hybrids, it’ll have two engines, including an electric motor. But in this case, the second will be the turbine, Goodwin’s secret ingredient. Whenever the truck’s juice runs low, the turbine will roar into action for a few seconds, powering a generator with such gusto that it’ll recharge a set of “supercapacitor” batteries in seconds.This means the H3’s electric motor will be able to perform awesome feats of acceleration and power over and over again, like a Prius on steroids. What’s more, the turbine will burn biodiesel, a renewable fuel with much lower emissions than normal diesel; a hydrogen-injection system will then cut those low emissions in half. And when it’s time to fill the tank, he’ll be able to just pull up to the back of a diner and dump in its excess french-fry grease–as he does with his many other Hummers. Oh, yeah, he adds, the horsepower will double–from 300 to 600.

The U.S. Senate has passed the new energy bill, which now goes back to the House for final approval before going to the president for his signature. But, as they say, there’s no free lunch.

While the legislation includes the landmark increase in fuel-economy standards for vehicles and a huge boost for alternative fuels, legislators caved in to oil and utility companies and stripped the legislation of a $13 billion dollar tax increase on those industries.

But that isn’t all, the bill also removed a requirement that utilities nationwide produce 15 percent of their electricity from renewable sources. Another example of the incredible clout of oil and utility company lobbyists in the nation’s capital.

The full legislation easily passed the House of Representatives last week, and that’s when the industry boys focused on Republican members of the Senate and the White House. President Bush has repeatedly threatened to veto the bill if the offending sections were not removed. Read the rest of this entry »

We don’t need new technology to save us, just a little ingenuity.

After a few minor tweaks, Ernie Rogers can get up to 76 mpg in his 2003 VW diesel Beetle:

He drove 1375 miles…[on] just 18 gallons of fuel– 1200 miles of which was accomplished on just one tankfull (15.5 gallons). His trip fuel economy was 76 miles per gallon. Rogers’ car included several small refinements that added up to the exceptional mileage: a drag reducing device he designed and built himself (pictures [here]), lower-rolling-resistance tires, low-friction engine oil, and use of a B5 biodiesel blend fuel to increase efficiency and improve emissions.

That’s right, it’s a non-hybrid that puts the Prius to shame. Granted, this test was at 55 mph, but the VW still gets between 57-65 mpg at normal freeway speeds. Read the rest of this entry »
