The aerodynamics of the XL1 are superb, thanks to the sports car design principles that Volkswagen have adopted. The car weighs just 1753 pounds and has a drag coefficient of 0.19 which helps the car cruise at a constant 62 mph while using as low as 8.4 PS. When running on batteries alone, the car requires 0.1 kW to travel more than a kilometer. With such less amount of power being used, the XL1 emits just 21 g/km of CO2 and the credit is to be given to its lightweight design and aerodynamic efficiency. The plug-in hybrid’s powertrain consists of a 35 kW two cylinder RDI diesel engine and a 27 bhp electric motor. The power is transferred to the wheels via a seven-speed DSG® dual-clutch automatic transmission. The XL1 can achieve a top speed of 99 mph and accelerates from 0 to 62 mph in 12.7 seconds. While vehicles of XL1’s category are not meant to offer everyday utility, Volkswagen engineers and designers successfully came up with a body design that made the XL1 more of an everyday car. Compared to the previous prototypes where the driver and passenger sat in a not so convenient arrangement, the XL1 offers a more conventional side-by-side seating arrangement. In Volkswagen’s words, the XL1 is a car of the future built for today.
