The news is sort of old, but I didn't find it on CR anywhere--sorry if it's a repost.
The Volkswagen L1, scheduled for arrival on U.S. shores in 2013. One liter diesel hybrid twin, two seater, gets around 160 mpg, range of over 400 miles, top speed of 100 mph.
Unveiled last fall as a concept car, VW reports it is production-ready. The prototype got over 180 mpg, but VW has backed-down on that claim for the production version. This is going to be looking especially appealing if gas is $5/gallon by then.
Link has photos and a nifty 2-minute video:
