Conventional drag racing is pretty much the furthest thing from a green sport, but that doesn’t stop me from enjoying the hell out of it. Yet even this tire-melting, gas-wasting sport is diving into the realm of alternative fuels for a variety of reasons.

Roush, a leading builder of aftermarket Mustangs, is developing two Mustangs for the drag strip powered not by gasoline, but clean-burning propane.

The new Volkswagen Scirocco is one of those cool cars America will never get (yes, I know we had it once, but the new one is sooooo much cooler). VW’s hot little hatchback has the looks and power to make most American small cars cringe in fear. Even cooler? They are working on a version that runs on carbon-neutral bio compressed natural gas.

Try saying that five times fast!

Many of the advancements made through racing and hot rodding have been passed down to the passenger car segment. Nothing quite stimulates innovation like pushing a vehicle to its limits. AFVTech, an alternative-fuels conversion company, is building a compressed natural gas (CNG) hot rod based on the classic ‘33 Ford coupe.

Equipped with a hand built LS7 engine (the same motor found in the Z06 but massaged to run on higher-octane CNG), AFVTech expects their Green Rod to make 600 horsepower.

Here’s one for the “surprising” list: a consortium of researchers and business partners at the University of East Anglia in Britain has found that they can convert diesel buses to run on either diesel or methane for a “small fraction of the cost” of purchasing a natural gas-only bus. The implications for Britain’s (and the world’s) fleets of already-existing diesel buses are huge.

The buses will run on biomethane — which is methane captured from landfill decomposition or other sources of surface biological decomposition and not derived from buried fossil sources. Methane is a large part of what makes up natural gas. According to the consortium, the converted bus will reduce emissions of pollutants and greenhouse gases by about half when compared to a standard diesel-only bus.

The converted vehicle was originally part of the local bus fleet run by the Anglian Bus & Coach company. After conversion of the standard Mercedes diesel engine, the bus now runs from 60-80% of the time on biomethane and the rest on diesel. Having the option to switch back and forth provides flexibility to the bus operator in the case of a shortage of either fuel.

Natural gas conversions don’t not have to cost that much: there is no technological problem driving what it truly needs to cost for auto mechanics to make a living at it. The true cost is only a few hundred dollars in parts and labor. The reason for this incredible difference is exceedingly interesting, as Robert Rapier notes in a well researched piece over at The Oil Drum on  the feasibility of switching from Gasoline to Natural Gas.

Not only is the reason interesting, but embedded in the reason is the simple way to solve it. Then converting cars to Natural Gas could cost what it actually costs; just a few hundred dollars - an hour’s work; a few parts.

We could cut our very hoggy national carbon footprint by switching to natural gas which we now have an abundant supply of if these new natural gas reserve numbers are even remotely accurate. So we could drive  less hoggy on somewhat cleaner fuel. And - (supposedly) in the carpool lane

The VP of The Auto Channel claims that this cost is unnecessary:

AT&T just announced that it will spend over half a billion dollars over the next 10 years in an attempt to reduce fuel usage and ostensibly, stimulate the economy. CEO Randall Stephenson stated that companies like AT&T have an “obligation to make investments that will drive the nation’s economic growth and productivity.”

To meet this obligation, AT&T will expand its alternative-fuel vehicle fleet from 100 to 8,000 vehicles by 2020. These vehicles will be U.S.-made compressed natural gas vehicles, amounting to $350 million worth of the total $565 million. Another 7,100 vehicles in AT&T’s passenger fleet will swapped out for electric-hybrids.

Waste Management of Seattle has begun construction on a new compressed natural gas (CNG) fueling station and unveiled a fleet of CNG-fueled solid waste collection trucks. The Seattle project is part of a larger national effort to cut the company’s CO2 emissions by 15% by 2020.

Waste Management is investing $29 million in 106 new vehicles and an additional $7.5 million to build a compressed natural gas fueling station in Seattle. When complete, the station will open to the public and within five years all 180 collection trucks in the Seattle fleet will be fueled by CNG.

Nationally, Waste Management already has 265 CNG and has 418 LNG (liquified natural gas) vehicles; and by the end of 2009, the company expects to have 500 LNG vehicles and 299 CNG vehicles in service.

As part of a broader national effort to convert trucks to CNG, the plan would seem to dovetail nicely with what has been proposed by T. Boone Pickens. In addition to advocating for more wind energy to power our light cars and trucks, Pickens supports converting the nation’s truck-fueling infrastructure to natural gas.

In California, the CNG conversion qualifies Carl Tankersley to drive solo in those highly desirable diamond lanes. Yet, although he prominently displays his carpool and CNG stickers as required by law, that doesn’t seem to be enough to stop the cops from disturbing his 30 minute commute on a fairly regular basis.

Four-door sedans continue to be popular vehicles for fleets and individuals because they offer the right amount of space for 4 or 5 passengers and enough cargo space for a taxi. With reduced greenhouse gas emissions becoming a priority for fleet managers and millions of conscientious consumers, finding new sedans that fit the bill can be confusing.

The following 10 four-door sedans have the lowest greenhouse gas emissions per mile of any vehicles available for volume commercial sale in 2009. In many cases, they also have the best fuel economy. Most are already selling in quantity. In a few cases, I am betting that the manufacturer will sell 1,000 of them to fleets by the end of 2009.

Buying these clean cars often gives fleets tax breaks and special funding opportunities.

Much of the attention surrounding the upcoming 2008 LA Auto Show (Nov. 21-30) has been directed at cars like the 2010 Ford Mustang and the 2009 Nissan 370Z. Yet, while glitzy, fast, and heart-poundingly desirable, these types of cars already seem like relics of a different era — a weird and surreal window on the past. To celebrate them feels mostly cheap and material, and does a disservice to the reality of our current world.

Given announcements last Friday that the American auto industry is on the brink of extinction, it seems to me that the more important cars at the show are the ones that, if they’re smart, the American auto industry will quickly turn to as the future of transportation. In honor of these sentiments, it’s only fitting for Gas 2.0 to do a preview of the cars and technologies you care about, and leave the relics to the pros.

I’ll be covering the LA Auto Show during press days on November 19-20, so stay tuned to Gas 2.0 for live coverage. Until then, check out the small taste of what’s to come below.

A decade after their first unpopular attempt at a natural-gas vehicle, Toyota says they are looking to CNG for the future.

High gas prices have made natural-gas vehicles more desirable, but Honda is still the only major carmaker currently offering a CNG vehicle. While their car is only available in California and New York, Honda says they can’t keep their Civic GX in stock due to popularity, and plans to build 2,000 more for 2009. Toyota wants some of the pie.

Despite claims to the contrary, it seems like General Motors is getting more and more involved in the refueling business. GM has already invested heavily in two different cellulosic ethanol companies (Coskata and Mascoma), and has now partnered with Clean Energy Fuels Corp. to open a hydrogen fueling station near the Los Angeles Int’l Airport (LAX). The station will be located at Clean Energy’s compressed natural gas (CNG) facility and should be operational by the fall.

Clean Burning Natural Gas Vehicles (NGVs) are hot commodities in some parts of the country, where fuel can sell for as low as $0.63 per gallon.

Unlike the world’s most fuel efficient car (VW’s 285 MPG bullet), the Honda Civic GX looks like a standard passenger vehicle. What makes it special is what you don’t see: tailpipe emissions that are often cleaner than ambient air.

The Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004.

And get this: in Utah, natural gas can be purchased for $0.63 per gallon.

While the national average price of gasoline is now $3.60, some residents of Utah are happily filling up on compressed natural gas (CNG) at $0.63 per gallon. That’s the country’s lowest price for CNG, which has understandably caused a surge in demand for vehicles running on a fuel that one man described as “practically free.”

So far, CNG vehicles haven’t made a blip on my radar screen, even though the group Natural Gas Vehicles for America (NGVA) estimates there are 150,000 NGVs on U.S. roads today and over 5 million worldwide. It took a phone call from sunny Southern Utah to clue me in to recent developments, which include a local refueling station overflowing with CNG-hungry vehicles.
