The Audi TT Clubsport Turbo concept will make its in-the-flesh debut at the Worthesee festival in Austria, which starts on May 13.
Under the bonnet, the Audi TT Clubsport Turbo concept features a 2.5-litre twin-turbocharged five-cylinder engine with 441kW of power and 650Nm of torque.
Power goes to the ground via a permanent all-wheel drive system and a six-speed manual transmission. Tipping the scales at 1396kg, the Clubsport Turbo can race from 0-100km/h in 3.6 seconds and hit a top speed of 310km/h.
Rather than two exhaust driven turbos, the Clubsport Turbo features, what the company calls, an electric biturbo layout. At low engine speeds, air is forced into the engine by an electrically powered compressor — an electric turbo, if you will. An exhaust driven turbo kicks and replaces the electric turbo at higher engine speeds.
Power for the electric compressor is supplied via a separate 48V electrical system. Energy for this system is captured via regenerative braking and stored in a lithium-ion battery pack under the boot.
Last year Car Advice sampled a similar system on the track with the Audi RS5 TDI Concept.
It’s easy to tell the Clubsport Turbo from production versions of the TT. This is thanks primarily to the car’s wider and squarer wheel arches. Overall the concept is 140mm wider than the regular TT.
At the front, rear and sides, the concept features large vertical vents which help to keep the car’s brakes cool. There’s also a larger grille flanked by matrix LED headlights, redesigned air splitters, a side exhaust on the driver’s side, and a manually adjustable rear wing made from carbonfibre-reinforced polymer.
The Clubsport Turbo rides on 20-inch alloy wheels clad in 275/30 tyres. Stopping power is provided by carbonfibre ceramic discs at all four corners, with the front discs measuring 370mm in diameter.
Inside, the TT’s rear seats have been removed and replaced by a lightweight titanium roll cage. Also gone is the climate control system, while much of the door trim has been replaced by a carbonfibre shell and a simple metal door pull.
For the driver and front passenger there are racing-style bucket seats with four-point harnesses. In front of the driver is a revised steering wheel with prominent round buttons for the engine starter, drivetrain mode selector, traction control and pit lane speed limiter.
