Despite evidence that the production of ethanol may actually increase carbon emissions as opposed to reducing them, almost every major auto manufacturer either has or is working on options that are capable of running on E85 (a combination of 85 per cent ethanol and 15 per cent gasoline).

GM Ceo Rick Wagoner claims that if all GM, Ford and Chrysler flex-fuel units currently on the road, as well as the ones in the works, ran on E85, it would add up to a savings of 109 billion litres of gasoline each year. Furthermore, if all vehicle manufacturers in the U.S. worked to do the same, that number would jump to 200 billion litres, which accounts for about one-third of worldwide annual fuel usage.

As the cost of fuel rises and talk of global warming spreads, automobiles capable of running on alternative fuel are rapidly gaining a reputation amongst those seeking fuel efficiency and environmental safety. The concept has caught on enough for producers to start looking into offering ethanol-capable luxury vehicles. Even Ferrari has jumped on the bandwagon, unveiling an ethanol-capable F430 Spider at the recent Detroit Auto Show. The vehicle reduces emissions by five per cent, however it may take multiple corn fields to power it if driven to its full potential.

Biofuels are being considered as a short-term solution, but it is the hybrids these manufacturers expect to see stick around. The new two-mode technology will make it possible for those who love their gas-guzzling monstrosities to keep driving them while mitigating the risk to the environment. Regardless of longer-term answer, the key message seems to be that auto manufacturers recognize the need to step up their game and offer drivers the luxury, quality and convenience they're used to in an eco-conscious way.
