Wolfsburg, Germany – Volkswagen has unveiled its new XL1 plug-in diesel hybrid at the Qatar Motor Show. The concept car, which represents the third evolutionary stage of Volkswagen’s 1.0-litre car strategy, has a combined fuel consumption of 0.9 L/100 km.
The concept also attains a CO2 emissions value of 24 grams per kilometre, thanks to a combination of lightweight carbon fibre parts, very low aerodynamic drag, and a plug-in system of a two-cylinder diesel engine, seven-speed dual-clutch transmission and lithium-ion battery. It can be charged from a conventional household electric outlet and can be driven for up to 35 kilometres on electricity alone.
The XL1 uses a two-passenger side-by-side design, rather than the tandem arrangement in the one-litre concept cars presented in 2002 and 2009. Wing doors make it easier to enter and exit the car. Further progress has also been made by manufacturing body parts from carbon fibre reinforced polymer parts, a technique used in Formula 1 car construction, but with significant reductions in production costs through a new system, developed and patented by Volkswagen and its suppliers, known as advanced resin transfer moulding.
