The Ferrari F430 Spider Bio Fuel
Fast high-end sports cars are generally not considered to be eco-friendly, with their gas guzzling turbo engines and energy-sucking luxury features. But that's not to say they aren't trying -- Ferrari for example, revealed their F430 Spider Bio Fuel model earlier this week in Detroit. It burns a mix of 85% natural ethanol and 15% gasoline, which results in +10hp (meaning its got a solid 500hp to work with) and a 5% increase in gas mileage over its gas-only counterpart. As for now the F430 Spider Bio Fuel is only a concept, but Ferrari says they'd like to put it into production as part of their efforts to cut emissions by 40% by the year 2012. Like the looks of it?
