The Ducati 1199 Superleggera has the best power-to-weight ratio of any production motorcycle in history. In the world of the motor car, the Volkswagen XL Sport achieves something similar. In this case it is the ratio between weight (890 kg), power (147 kW / 200 PS) and aerodynamics (cd x A = 0.44 m2) that currently makes this concept car the fastest 200 PS car in the world. No other sports car has ever reached a top speed of 270 km/h with 200 PS. One stand-out feature in this is the vehicle’s aerodynamics. As indicated above, the coefficient of the drag coefficient (0.258) and the vehicle’s frontal area (1.7 m2) is 0.44 m2. This is one of the best values ever achieved and a major triumph for Volkswagen’s aerodynamics engineers and designers, made all the more impressive due to the fact that as a thoroughbred sports car, the concept’s design brief demands wide tyres, a high requirement for cooling air and optimal downforce. There are a number of individual features that contribute to the XL Sport’s arrow-like performance in addition to the uncompromising aerodynamic styling of the body. These include special air curtains that direct the air in the frontal area into specific channels, wheel arch ventilation, a further optimised underbody, lift-reducing air ducts in the bonnet, an extendible rear spoiler (powered by the same unit as in the Lamborghini Aventador) and adaptive waste heat vents incorporated in the rear hatch (louvre that opens and closes automatically as required to conduct excess engine heat away).
