What is it?
Audi’s experimental lightweight version of the A5 coupe. The standard A5 is built around a conventional steel monocoque chassis, but this car is built around an aluminium spaceframe chassis, clad in aluminium panels. The boot and bonnet are made from carbonfibre-reinforced plastics.
Under the skin of the prototype is Audi’s familiar 2.0 TSI turbocharged engine, wound up to 208bhp and driving all four wheels.
Audi says this car points the way forward for the company. Aluminium construction will become more common, allowing future cars to benefit from all-round ‘downsizing’.
