The heart of the Audi A1 club sport quattro is a classic Audi gasoline engine – a five-cylinder unit displacing 2.5 liters with turbo charging and straight fuel injection. Compared with the version used in the Audi TT RS and RS 3 Sportback on which it is based, the output of the TFSI has been augmented dramatically to 370 kW (503 hp) and 660 Nm (486.79 lb-ft) of torque. Maximum power is obtainable between 2,500 and 5,300 rpm.
The powerful engine catapults the car from 0 to 100 km/h (62.14 mph) in 3.7 seconds. From 0 to 200 km/h (124.27 mph) takes just 10.9 seconds, while the car goes from 80 to 120 km/h (49.71 to 74.56 mph) in fourth gear in just 2.4 seconds. A six-speed manual transmission and quattro permanent all-wheel drive, both taken from the TT RS and enhanced, deliver the power to all four wheels. Top speed is governed at 250 km/h (155.34 mph).
The Audi A1 clubsport quattro showcar rolls on 255/30 low-profile tires mounted on 19-inch alloy wheels with a sole turbine design. Sitting behind the wheels are large, inside ventilated disc brakes. Up front, six-piston calipers grab perforated carbon fiber-ceramic discs. Large steel discs are mounted on the rear axle. The coilover suspension of the A1 clubsport quattro features adaptable compression and rebound damping.
