The idea is to take the research and technology that went into the XL1 and apply it something a bit more exciting. So use the carbon fiber body and try to maintain the .189 coefficient of drag but stretch and widen the platform a bit and give it the 2.0T out of the Golf GTI with some tweaks.
Combine the targeted 1873 pound curb weight with horsepower in the mid 200's and now you have something interesting. Porsche 911 Carrera Performance but with diesel Golf efficiency. That is a hell of a lot more exciting than praying you can pick up enough speed to merge onto the freeway.
Oh, the price is expected to drop to from the 1XX,XX rance for the XL1 to something around $60,000. That sounds ambitious but if they can pull it off it would be amazing. Will it get approved for production? Probably not, but out of these two cars we all know which one should.
