Heading to the Worthersee show later this month (May 2015) is this Audi TT Clubsport Turbo. It features Audis innovative electric turbocharger technology but is mostly about making sure the VW and Audi lovers get a suitable concept to be excited about.
Electric turbocharging is a smart solution to eradicating turbo lag at low RPM. When there is not enough exhaust gas to spin the turbocharger adequately, it calls on the cars secondary electric compressor to provide boost. This allows instant boost and engineers can focus on ensuring high power and high revs from the power unit.
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.
The Audi TT Clubsport Turbo makes use of the 2.5-Litre, five-cylinder unit complete with two turbos that enable a massive power output of 441 kW and 650 Nm of torque. Better yet the power unit is hooked up to a six-speed manual gearbox. Zero to 100kph takes just 3.6 seconds and will roar on to a top speed of 310kph.
The design takes an AudiTT to an extreme. The fenders of the show car painted in the exterior colour Ferro Titanium are open at the front and rear. Air from the cars slipstream flows through them to cool the brakes. The manually adjustable rear wing is a development from the Audi Sport TT Cup with which the brand very recently launched a dedicated race series. It is now 20cm wider, and the side flaps were given a new geometry. The wing consists of carbon-fibre 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 diffuser at the rear whose lateral segments reference the motif of the air inlets.
Its unlikely Audi will unveil its TTRS performance model with the five-cylinder turbo unit under the hood. More than likely it will be redeveloped version of the 2-Litre turbo that sits in the Golf R and current TT.
