There is also 600Nm of torque courtesy of a 2.5-litre, five-cylinder TFSI engine as seen in the RS Q3. With a kerb weight of 1,527kg the A3 Clubsport quattro concept travels from 0-100 km/h in 3.6 seconds on the way to a top speed of 309km/h. Extensive modifications make this performance possible. These include a large turbocharger with up to 1.5 bar of relative boost pressure and a modified intercooler.
In addition to its distinctive sound and technology, the 2.5 TFSI also looks stunning set beneath its carbon fibre-reinforced polymer (CFRP) bonnet. The Audi A3 Clubsport quattro concept features a seven-speed S tronic transmission with a compact three-shaft layout. Its tall seventh gear reduces fuel consumption, and the final gear ratio has been modified accordingly.
The heart of the quattro all-wheel-drive system is a hydraulically activated, multi-plate clutch on the rear axle that has been specially designed for the high torque of the powerful five-cylinder.
Aluminium components in the front MacPherson suspension reduce the weight of the unsprung mass. The four-link rear suspension can process the longitudinal and transverse forces separately. Compared to the production Audi S3 Saloon, the body has been lowered by 10mm and spring and damper settings have been adjusted to suit the increased performance.
The A3 Clubsport quattro even features an air brake, the rear segment of the boot raises from its standard spoiler setting to a near-vertical position. At 250kmh it is said that the air brake reduces the stopping distance by around twelve metres.
The cabin features racing seats with high side bolsters await the driver and front passenger. The backrests are open-worked below the integrated head restraints and CFRP shells cover the backs
Black is the dominant colour in the show car's interior. The upholstery features light grey piping and contrast stitching in Sepang blue. The headlining and the pillars are covered in black Alcantara, and the decorative inlays are brushed aluminium.
