Every year in summer, the Volkswagen Group presents new technologies and sporty derivatives from Volkswagen, Audi, Skoda and Seat in in the lakeside town of Reifnitz, in the state of Carinthia, Austria. Following the teaser of Golf GTI Clubsport, VW’s contender for Worthese 2015, the Group has now revealed the Audi TT Clubsport turbo concept for the Wörthersee GTi-Treffen or in English, the “Worthersee Meeting”. It will be on display from 13 to 16 May.
The concept makes use of a 2.5-litre TFSI five-cylinder petrol engine featuring an electric biturbo. The 2,480 cc engine produces 600 hp and 650 Nm of torque. The engine sends power to all four wheels via a 6-speed manual transmission and the compact sports car weighs 1,396 kg (unladen). It can sprint from standstill to a speed of 100 km/h in just 3.6 seconds, and go further to hit an unrestricted top speed of 310 km/h.
The company is close to production readiness in using TDI engines with electric turbocharging. It is reportedly testing the TDI diesel engine-powered SQ7 with electric turbocharging. The technology essentially aims at filling in the turbo lag. Thanks to this new technology, the conventional turbocharger can be designed specifically for high charge pressures and consequently for high engine power. The electric turbocharger handles the job of ensuring spontaneous response at low engine speeds. The electrically driven compressor boosts torque by up to 200 Nm.
The electric turbo isn’t the only exclusive feature of this beastly TT. Audi has made adjustments for a “throaty sound” from the exhaust system which is designed in a way that ensures there’s minimal back-pressure; a side pipe to the ambient air is located immediately after the racing-type muffler. The engine is cooled by a racing-type radiator.
The large splitter at the front, air inlets, side panels, side sill trims, rear diffuser as well as the manually adjustable rear wing is an advanced version of the one seen on Audi Sport TT Cup – are all made of carbon-fibre reinforced polymer (CFRP). The Singleframe grille and the air inlets are are optimized for maximum air passage.
Inside, there’s a protective cage made of ultra-high-strength titanium tubes in the rear. CFRP and black Alcantara are used for interior elements. There are two race car bucket seats with four-point harnesses. The seats feature coral orange Alcantara upholstery with contrasting stitching and piping. There are four satellite buttons on the multifunction steering wheel to control primary functions, including engine start-stop and drive mode selection.
