After more than a decade of research and development, VW engineers made the 1-liter car possible, as the German carmaker unveiled the production version of its ultra-economical XL1 car.
The XL1 by Volkswagen is the most efficient of all production cars with a fuel consumption of 0.9 l/100 km. Thanks to its plug-in hybrid system, the two-seater can also be driven for up to 50 kilometres locally in pure electric mode, with zero emissions at point of use.
The XL1 follows pure sports car design principles to achieve maximum fuel efficiency: low weight (795 kg), perfect aerodynamics (Cd 0.189) and a low centre of gravity (1,153 mm high). This gives the XL1 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 car’s excellent fuel economy is due to systematic lightweight construction (among other things, monocoque of CFRP), perfect aerodynamics and the plug-in hybrid system – consisting of a two-cylinder TDI (35 kW / 48 PS), the E-motor (20 kW), a 7-gear dual-clutch gearbox (DSG) and a lithium-ion battery (capacity: 5.5 kWh). All these enable the XL1 to emit only 21 g/km CO2.
The XL1 has a top speed of 160 km/h (electronically limited) and accelerates to 100 km/h in just 12.7 seconds. The car will be built in limited numbers.
