This car is not as boring as it looks.

As we have written about at length, ethanol fuel is gaining momentum as a possible alternative to gas.

The Saab BioPower E100 concept vehicle, which is at the New York Auto Show, runs on E100 (100 percent bioethanol fuel). The BioPower E100 would be a turbocharged 2.0 liter engine that offers 300 horsepower and runs on bioethanal.

While the BioPower E100, which debuted at the Geneva Auto Show, is only a concept, Saab does sell the Saab 9-5 BioPower, which runs on E85.

The Saab 9-5 BioPower, which is sold in Europe, is part of Saab's flex-fuel lineup.

Flex-fuel vehicles, are just what they sound like: vehicles that are flexible regarding the kind of fuels they can use, so you can still fill up on ordinary gas if you find yourself in a place where ethanol is not an option.
