Dr. Thomas Gaensicke, Volkswagen AG, talks about the 1-liter car built by Volksagen. Billed as the most fuel-efficient car in the world, VW has created a two-seater made out of magnesium and carbon-fiber.

The tandem, single-cylinder naturally aspirated diesel fueled engine with direct fuel injection and a displacement of .3 liters. The 1-liter gets 238 miles per gallon, 8.5 horsepower and 13.5 lb/ft of torque at 2,000 rpm.

The one-liter car weighs 639 pounds, 49.1 inches wide, 43.7 inches high and has a drag co-efficient of .159.

Personally, the 1-liter looks like an airplane fuselage without the wings. The open-air canopy is reminiscent of a Thorp T-18 homebuilt airplane, which gives one a feeling of more room.
