Volkswagen has plans to produce a 1-liter car by 2010 that'll get a whopping 200 miles per gallon, making it one of the most fuel-efficient cars on the road. It's not going to come without its drawbacks, however, as reaching a figure like that isn't going to happen with a car with any substantial weight.
First of all, it'll be a two seater, with the passenger sitting behind the driver. As for trunk space? Forget it. And if you're hoping to jet around quickly, accept that this guy will top out at 75MPH on the highway. But hey, you'll have to stop for gas like once a month, which would be pretty great seeing how ludicrous gas prices have gotten. It's all about compromises, people.
