N only eleven curves instead of 73, only 4.113 instead 20.832 kilometers, only a maximum of eight instead of 17 percent incline - the Spanish Parcmotor de Castellolí race track is not a substitute drug for the Nordschleife either. But just at that moment, when the new Audi TT Cup racer plunges down the asphalt strip and the run-off areas are as stingy as in Fuchsröhre, Kessel and Co., it tingles almost like in the Green Hell.

Welcome to the racing car for the new Audi Sport TT Cup junior brand cup, which will be launched for the first time in 2015 as part of the supporting program for six DTM events.

In December 2014, 165 applications were turned into over a two-day period Racing driver castings filtered out the best 18 drivers from 13 nations. “There were also inquiries from people in their mid-fifties who said they had once raced in the Audi 50. We charmingly explained to them that offspring is not a very flexible term. The average age is 21 ', says Rolf Michl, project manager of the TT Cup. The starting field is complemented by six guest starters in each of the twelve races of the season.

It is not without reason that the muscle TT feels so comfortable on the slopes in the Catalan hinterland today. “The cars are assembled by our partner Seat Sport in Martorell, Spain, but the entire development was carried out at Audi,” explains Detlef Schmidt, technical project manager of the Audi Sport TT Cup.

Audi TT Cup with only 1,125 kilograms

The Bavarian-Spanish racing car project tastes just as delicious as the combination of wheat beer and tapas when braking for the first corner. 200, 150, 100 meters - the brake pedal is only hacked at the 100 meter sign. The steel braking system bites with commitment and enables surprisingly late braking points for this vehicle class. The TT Cup shines with similarly harmonious ABS coordination as its series brother TTS.

Speaking of series: The new brand cup racer is based on the TTS street model, but it will start with front-wheel drive. All-wheel drive was not an issue for weight reasons and before the extensive ban on circuit racing. “After we receive the series body shell, we first remove some sheet metal. For example, we also move the seat 60 mm to the center of the vehicle. This gives us space for side impact protection. In addition, every load-bearing seam is re-welded, ”says technician Schmidt.

Despite thewelded-in safety cell made of around 35 meters of chrome-molybdenum steel, the body of the TT Cup weighs around 20 kilos less than the standard body. The minimum weight of the vehicle is 1,125 kilos. No wonder that the emptied novice stirs up curves much more lightly than the 1,438 kilo series TTS.

“I was really surprised at how precisely the car can be driven,” said racing professional Markus Winkelhock to the guest driver made the mouth watery before the track test. The ex-Formula 1 driver and current Audi GT works driver supports the youngsters as a coach in the TT Cup.

Two-liter TFSI with 310 hp in the TT Cup

With temperature-controlled slicks, the TT Cup storms around the course with an impressive level of grip and largely neutral handling. The well-balanced chassis has multiple setting options. The basic set-up is determined by the cup line for each route, while the young drivers are only allowed to change the stabilizer on the front and rear axles and the tire air pressure.

'There is also a button on the steering wheel with which three settings for traction control and the electrohydraulically controlled VAQ-Haldex transverse lock can be selected. Position 1: dry track, new tires, a lot of grip, position 2: rather worn tires, little grip, position 3: wet, ”Detlef Schmidt explained earlier. With good traction, the TT racing car now turns the corner in the most aggressive setting of the barrier. It acknowledges an all too digital accelerator pedal, especially in tight bends at full load, nevertheless with a slight slip on the drive axle.

If you start with a smooth driving style, you can concentrate on the yellow button on the top right of the steering wheel. Thanks to the push-to-pass function, the engine output can be increased by 30 hp at the touch of a button. But even without an activated boost button, the 310 hp two-liter TFSI pushes powerfully.

Audi TT Cup with a maximum of 239 km /h

'The engine and transmission package are classic series components. Exactly one part of the crankcase ventilation was changed on the engine in order to counteract the higher G-forces “? (if change in the quotation is allowed). The gears are series gears, but they have been paired differently so that we have a shorter overall gear ratio. At 6,800 revs, we reach a top speed of 239 km /h, ”technician Schmidt had previously revealed.

The transmission electronics were specially applied, but at the limit, the six-speed dual clutch transmission cannot hide its series origin. When downshifting, the S tronic does not change gears quite as quickly as, for example, the sequential racing transmission in the Audi R8 LMS GT3 racing car.

GT3 is a good keyword:Audi GT3 program. Our goal is to qualify young drivers for higher tasks and then develop them further in the Audi family, 'says project manager Michl.

But the Audi TT Cup racer should also be entrusted with higher tasks in the future will. 'We have designed the tank for 100 liters so that the TT can also be used for other purposes, for example for long journeys,' adds Schmidt, head of technology. Which brings us to the Nordschleife mentioned at the beginning.
