For example, the XL Sport has a number of special aerodynamic tweaks including special air curtains, wheel arch air outlets, an optimised underbody, a diffuser that reduces aerodynamic lift and adaptive exhaust heat vents integrated in the rear lid.
The concept car is slightly longer and wider than the XL1 with a length of 4291mm, width of 1847mm and height of 1152mm. It has a 2424mm wheelbase, longer than the XL1, significantly wider wings and larger wheels.
The extendible rear spoiler is powered by the same apparatus unit as in the Lamborghini Aventador. It also has adaptive waste heat vents incorporated in the rear hatch – the louvres opens and closes automatically as required to conduct excess engine heat away. The air supply for cooling the Ducati engine is via vents in the rear wings.
It has a carbonfibre tub like XL1, with steel space frames at either end to hold the suspension. They are supplementary to the carbonfibre tub and aluminium crash structures. The suspension consists of a double wishbone front axle with the dampers connected below in a pull-rod configuration, and a double wishbone rear axle with the dampers connected above in a push rod configuration.
The tyres are 205/40 R18 at the front and 265/35 R18 and the rear, and the wheels are made from forged magnesium, which brings a total weight reduction of 23.9kg compared with aluminium wheels.
Like the XL1, many parts of the XL Sport's body are manufactured in carbon-reinforced polymer (CFRP), with a monocoque featuring slightly offset seats for the driver and passenger.
The interior boasts a number of changes over the standard XL1, such as a digital instrument cluster, with an individual lap time and oil pressure display. A flat carbonfibre part that extends the top of the instrument cluster covering to eliminate reflections in the windscreen.
“The XL Sport is based on the XL1, our lightweight efficiency champion with an extremely low drag coefficient and excellent aerodynamics. We’ve improved the aerodynamics but maintained the sporty look,” said a Volkswagen spokesman. “It has a heart made by Ducati.”
Volkswagen describes the XL1's interior as "highly influenced by motorsport". There’s no word on whether Volkswagen intends to put the striking car into production, but last year the manufacturer stated its intention to build one example of the car to gauge reaction.
The German manufacturer is expected to reveal more details of the concept at its Paris motor show press conference at 0850hrs tomorrow.
