Prius light cycle
At the Geneva Motor Show earlier this year, Toyota revealed the Tron car. No, wait, I mean it revealed a Prius concept car that looks an awful lot like a four-seater light cycle.
More recently, Toyota has shown off another concept car, the 1/X, so-called because "it weighs 1/Xth the weight of other similar sized models." Which is to say, it's about 1/3 the weight of a Prius; its frame uses carbon-fiber reinforced plastic. And it gets about double the gas mileage of the Prius.
But of course these are just concept cars; there's no indication that they'll ever go into production.
