Audi is presenting the A3 clubsport quattro concept at this year's Wörthersee Meeting in Reifnitz from May 28–31. The concept study is based on the S3 Sedan and has a five-cylinder TFSI engine under the hood producing 525 hp.

Based on the S3 Sedan, the show car is equipped with a powerful five‑cylinder TFSI engine. The 2,480 cc five‑cylinder produces 525 hp for a specific output of 211.7 hp per liter. With a total weight of 3,366.5 lb, this corresponds to a power-to-weight ratio of 2.9 kilograms (6.4 lb)/hp. Maximum torque of 442.5 lb‑ft is available between 2,300 and 6,000 rpm. The Audi A3 clubsport quattro concept accelerates from 0 to 100 km/h in 3.6 seconds and reaches a top speed of 310 km/h.

Extensive modifications make this extreme performance possible. These include a large turbocharger with up to 1.5 bar of relative boost pressure and a modified intercooler.

The Audi A3 clubsport quattro concept features a seven‑speed S-tronic with a compact three‑shaft layout. Its tall seventh gear reduces fuel consumption, and the final gear ratio has been modified accordingly. The driver can allow the dual‑clutch transmission to work fully automatically in modes D and S or choose to change gears manually using the paddles on the steering wheel or the shift lever. A launch control function manages starts with maximum power and controlled wheel slip.

Its advanced chassis enables the Audi A3 clubsport quattro concept to deliver its tremendous power to the asphalt dynamically and safely. Aluminum components in the front McPherson suspension reduce the weight of the unsprung masses. The four‑link rear suspension can process the longitudinal and transverse forces separately. The steering rack of the progressive steering system is designed so that the steering ratio becomes more direct with increasing steering input. In addition, steering boost decreases as speed increases.

Compared to the production Audi S3 Sedan, the body has been lowered 10 millimeters (0.4 in) and both the springs and dampers are very taut. All three parameters can be adjusted via the struts of the coilover suspension so that the show car can be perfectly adapted to the task at hand, be it on the road or the race track.

The lightweight body lays the foundation for the show car's low curb weight (without driver) of just 3,366.5 lb. The result is a race car‑like power-to-weight ratio of just 6.4 lb per hp. The spectacular appearance of the Magnetic Blue body immediately reveals the dynamics of the Audi A3 clubsport quattro concept. The Singleframe grille up front is framed in matt aluminum. A quattro badge adorns the grille's high-gloss black honeycomb insert, which has been optimized for high flow. The engine hood, whose front edge extends slightly over the grille and the LED headlights, sports the four rings.

A distinctive element at the front of the show car is the continuous blade of exposed CFRP below the Singleframe grille. Like the winglets on a model airplane, its ends are bent upward to structure the large air inlets framed in massive edges. As with a race car, a splitter at the bottom of the front skirt increases the downforce on the front axle.
