New York preview: ethanol-powered, aluminum Saleen S5S Raptor goes 200 MPH
Ethanol and aluminum technologies are green and, importantly, accepted by the super car community. Ethanol has lower energy and gets lower mileage than gasoline but a car can be tweaked to take advantage of the higher octane in ethanol to get more horse power. Use of lightweight aluminum saves fuel and it allows for higher speeds which is why sport car companies like Lotus, Ferrari and Tesla are using aluminum today.
We are still looking for a good, green reason why a car would need to go 200 MPH, though.
