Marking the third-generation of its ultra efficient concept, Volkswagen has taken the wraps off its XL1 Super Efficient Vehicle at the Qatar Motor Show. The XL1 follows in the footsteps of the One-Liter and L1 concept cars.

Highlighted by its sleek body shape, the XL1 registers a coefficient of drag figure of just 0.186. The XL1 has an overall length of 156.3 inches and, at 46.6 inches tall, is comparable in height to the Lamborghini Gallardo Spyder. Hit read more for details and pictures.
Like the previous L1, the XL1 uses a 0.8L two-cylinder diesel engine mated to an electric motor. However, power has been increased from the previous concept, with the diesel engine generating 47 horsepower and the electric motor adding another 27 horsepower. Power is sent through a seven-speed dual-clutch gearbox.
That extra power is needed as the XL1 weighs in at 1,650 pounds – nearly double the weight of the L1 concept. Still performance is decent, with the XL1 able to hit 62mph in 11.9 seconds on its way to a top speed of 99mph.
As one would expect, the XL1’s plug-in powertrain delivers some eye-popping fuel economy figures. Whereas the previous L1 concept could “only” manage 170mpg, the XL1 is said to be capable of returning 313mpg on the European combined cycle.
Although “still very much a concept” according to VW, the XL1 previews a forthcoming line of Super Efficient Vehicles from the German automaker. No official timetable for a production version of the XL1 has been set, but previous reports suggest such a vehicle could come to fruition by mid-decade.
