Audi wants to make his fans happy and joins the Worthersee Festival with a brand new concept, built on the current generation TT. The prototype is called Audi TT clubsport turbo and has a power-boosted 2.5 TFSI engine with an electric turbo.
From 2,480 cc of displacement, the five-cylinder engine produces 600 hp of power and 650 Nm (479.4 lb-ft) of torque, the latter from 3,000 to 7,000 rpm. This means that it produces 240 hp and 260 Nm (191.8 lb-ft) per liter of displacement.
Power is transferred via a manual six-speed transmission to an all wheel drive system, the traditional quattro. The TT clubsport turbo show car has an unladen weight of just 1,396 kg which helps the car to complete the standard sprint from 0 to 100 km/h in 3.6 seconds, and reach a top speed of 310 km/h (192.6 mph). 
“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.”
On the outside, the new Audi Tt clubsport quattro tries to be as aggressive as he can, with the addition of a new bodykit. The fenders of the show car – painted in the exterior color Ferro Titanium – are open at the front and rear. The wing consists of carbon-fiber reinforced polymer (CFRF) as do all other add-on parts: the air inlets and the large splitter at the front, the side panels and side sill trims as well as the voluminous diffuser at the rear.
