add a turbo diesel hybrid plug-in and that car would get crazy gas milage in the southwest. not to mention they are working on making carbon fiber way more affordable, and there is a form of graphite they are working on that is close to carbon fiber. if they get the weight down on the cars that will help out a ton as well. as long as the car companies can offer a car with a decent range and a fun to drive factor hybrid/alternative energy cars will catch on.
