Although it seems hard to believe, Volkswagen revealed today the production version of the XL1 a.k.a. the most fuel-efficient production car in the world, with a fuel consumption value of 0.9 l/100 km. Set to make its world debut in March at the 2013 Geneva Motor Show, the new Volkswagen XL1 uses a plug-in hybrid system consisting of a 0.8-liter two-cylinder TDI engine (35 kW / 48 PS), E-motor (20 kW / 27 PS), 7-speed dual clutch gearbox (DSG) and lithium-ion battery. The XL1 is able to sprint from 0 to 100 km/h (62 mph) in 12.7 seconds and has a top speed of 160 km/h (100 mph).
The big surprise is that the Volkswagen XL1 needs only 0.9 liters of fuel per 100 km, a record figure that has not been achieved by any other vehicle to date. Volkswagen XL1 has the ability to cruise on the road at a constant speed of 100 km/h using just 6.2 kW / 8.4 PS.
In all-electric mode, the XL1 requires less than 0.1 kWh to cover a driving distance of over one kilometer. The XL1 is an automotive hero that follows pure sports car design principles: low weight (795 kg), perfect aerodynamics (Cd 0.189) and a low centre of gravity (1,153 mm high).
Moreover, the XL1 emits only 21 g/km of CO2. In electric mode, the XL1 has a maximum range of 50 km. The XL1 is 3,888 mm long, 1,665 mm wide and just 1,153 mm tall. By usual automotive standards these are extreme dimensions.
