The Audi TT Clubsport Turbo impresses with its wide add-on parts, a huge rear
wing and electric biturbo technology.
"The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power," explains Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. "In our TDI engines, we are close to production readiness with this technology. We are now presenting it in a TFSI - here too, we are the first automaker in the world to do this. For our fans at Wörthersee, we have packaged the electric biturbo in a very sporty show car."
The Audi TT Clubsport Turbo has a power-boosted 2.5 TFSI engine with 591 hp (441) and 479 lb-ft (650 Nm) of torque, the latter available from 3,000 to 7,000 rpm. Power is transferred via a manual six-speed transmission.
Thanks to lightweight design, the TT Clubsport Turbo show car has an unladen weight of just 3,077 lb (1,396 kg). The car completes the standard sprint from 0 to 60 mph in 3.4 seconds, and its top speed is 193 mph (310 km/h). The TT Clubsport Turbo plays out its big advantage over the first few meters of a sprint. Its electrically driven compressor lets it cover up to 52.5 feet (16 meters) within the first 2.5 seconds - which is 20 feet (six meters) further than a comparable car without this innovation.
In front, there are lightweight race car bucket seats with four-point harnesses. The display and operating concept with the digital Audi virtual cockpit focuses on the driver, who can control all key driving parameters via four satellite buttons on the multifunction steering wheel.
Sporty materials such as CFRP and black Alcantara define the interior of the Audi TT Clubsport Turbo. The race seats are upholstered in coral orange Alcantara and feature contrasting stitching and piping. In the doors and on the center console, CFRP parts with their large surfaces create sporty accents, and the doors are closed by pulling on a tube-shaped grip with an Alcantara inlay. The air vents and gear shifter also have coral orange accents - the aluminum gear shift lever travels in an open shift gate.
An electrically powered compressor offers significant advantages: it revs up to maximum rpm rapidly and without any perceptible delay, and it continues to boost charge pressure when too little drive energy is left in the exhaust gas for the conventional turbocharger. This operating principle makes it possible to design the conventional turbocharger more specifically for high charge pressures and consequently for high engine power - the e-turbo assures spontaneous response and powerful sprints from low engine speeds at all times.
In an acceleration duel, the TT Clubsport Turbo effortlessly pulls away from a counterpart with an identically powered engine but no electric biturbo.
