Cigar-Shaped Car Is World's Most Fuel-Efficient

VW says the car will get 261 mpg.

VW says their diesel plug-in hybrid car will achieve 261 miles per gallon.

The high mileage is achieved thanks in part to the car's incredibly streamlined body, which has a low drag coefficient of only 0.189. The average modern automobile achieves a drag coefficient of between 0.30 and 0.35.

The XL1 should reach 62 mph in 12.7 seconds with a top speed of 98 mph.

The cigar-shaped body looks like it's right out of the Jetson's.
