VW-XL1

Some spy photo's of vw's high-efficiency XL1- "one liter" car.
Prototype was called "one liter", referring to the design criteria that it should use no more than 1 liter per 100 km.
Aerodynamic coefficient of 0.186, two cylinder diesel and 27hp electric motor.

Makes one think of a much earlier attempt at lower aerodynamic coefficient... (At higher constant speeds, sometimes more than 90% of the power needed to keep a vehicle moving is used to fight aerodynamic drag).
The "Pillbug", designed by professor Schlor around the early-mid 1930's. It had seating for 7 people. Aerodynamic coefficient was around 0.13 and a rear-engined Mercedes 170H chassis was used. (The beetle chassis was not available at the time).
