Audi has revealed the TT clubsport turbo concept digitally before its world premiere at Wörthersee Tour festival from May 13-16, 2015. The Audi TT clubsport turbo showcar is said to be the first application of electric biturbo propulsion in a TFSI engine. Almost close to being production ready, it churns out a massive power of 592bhp and peak torque of 650Nm, while doing a 0-100kmph in just 3.6 seconds.
The Audi TT clubsport turbo has a power-boosted 2.5L TFSI engine. From 2480 cc of displacement, the five-cylinder engine produces 592bhp of power and 650Nm of torque, the latter from 3,000 to 7,000 rpm. This means that it produces 237bhp and 260Nm per litre of displacement. Power is transferred via a manual six-speed transmission. Thanks to systematic lightweight design, the TT clubsport turbo show car has an unladen weight of just 1,396 kg. The car completes the standard sprint from 0-100kmph in 3.6 seconds, with a top speed of 309kmph. However, it is not just the power of the five-cylinder engine that is fascinating – so is its unmistakable throaty sound. The exhaust system is designed for minimal back-pressure; a side pipe to the ambient air is located immediately after the racing-type muffler.
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, which are extremely lightweight and wear-resistant. The front brake discs measure 370 mm in diameter. The compact 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.
The wings of the show car – painted in the exterior colour Ferro Titanium – are open at the front and rear. Air from the car’s slipstream flows 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 maximum air throughput. The manually adjustable rear wing is 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 wing consists of carbon-fibre reinforced polymer (CFRP) as do all other add-on parts.
Talking about the interior cabin, 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. 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 centre 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 aluminium gear shift lever travels in an open shift gate.
