At the L.A. Autoshow, Volkswagen unveiled a concept car with 3 wheels. VW claims it can get 46 mpg in the city, and can do 0-60 mph in 5.7 seconds. Yes, it is a concept car, but VW claims they are seriously considering production if customer interest is sufficient. They would go for about $17,000 or less.
Wonderful. But where's my damned Microbus?
actually, TDI's all get better than 46mpg highway, generally.
if it's gas powered it will be a little easier on greenhouse gasses, though.
