Audi has released more pictures of the TT Clubsport Turbo concept car ahead of the Wörthersee tuning show.
Said to have been visually inspired by the Audi 90 IMSA GTO race car of the late 1980s, the Clubsport Turbo has a power-boosted 2.5 TFSI engine that delivers 592 bhp of power and 479.4 lb-ft of torque, the latter from 3,000 to 7,000 rpm. This means that it produces 239 bhp and 191.8 lb-ft per litre of displacement. Power is transferred via a manual six-speed transmission.
The car completes the standard sprint from 0 to 62 mph in 3.6 seconds, with a top speed of 192 mph. The TT clubsport turbo plays out its big advantage over the first few metres of a sprint. Its electrically driven compressor lets it cover up to 16 metres within the first 2.5 seconds – which is six metres further than a comparable car without this innovation, according to Audi engineers. That is a difference of around one and one-half car lengths.
“The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power,” explains Audi development boss, Ulrich Hackenberg. “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.”
A dedicated 48-volt electrical sub-system – another technology precursor from Audi – supplies electrical energy to the turbocharger. A lithium-ion battery in the luggage compartment stores the energy that is generated by recuperation when coasting. A DC/DC converter provides the connection to the 12-volt electrical system.
The sports car takes a full stance on the road with track widths of 1,736 mm in front and 1,729 mm at the rear. The car is 4.33 metres long and 1.97 metres wide, including the side mirrors – 14 cm wider than the technical platform upon which it was based. Its angular wings contribute a separate additive shape to the car body.
The wings of the show car are open at the front and rear, allowing air from the car’s slipstream to flow through them to cool the brakes. The ‘Singleframe’ grille and large air inlets – whose vertical fins form a continuation to the light signature of the Matrix LED headlights – are also optimised for better air throughput.
The manually adjustable rear wing is claimed to be an advanced development of the Audi Sport TT Cup with which the brand very recently launched a dedicated race series. It is now 20 cm wider, and the side flaps, which feature the four rings, were given a new geometry.
The show car’s wheels are size 9.5 J x 20. Their six twin-spoke design is finished in a bi-colour look – both gloss turn finished and matt black – and the tyres are size 275/30. Carbon-fibre ceramic brake discs are mounted behind all four wheels, with the front brake discs measuring 370 mm in diameter.

I was curious if you ever considered changing the layout of your site? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 pictures. Maybe you could space it out better?
