Forget power, space, and speed: Volkswagen AG’s latest idea-on-wheels does not address the requirements of the average American family driver. What it can do is travel more than 100 kilometers on a single liter of fuel. Translation: 235 miles per gallon.

The car’s designers combined highly tuned aerodynamics, exotic materials, and a 0.3-liter diesel engine to achieve 0.99 liters per 100 kilometers. The project, the brainchild of engineer Thomas Gänsicke, is an engineering exercise and therefore has rather whimsical features. Most noticeable are the car’s canoe-like proportions: It’s 4 feet wide and 11 feet long. Occupants sit tandem, the passenger straddling the driver’s seat, both wedged under a 4-foot-long gullwing canopy. More here.
