(MENAFN - Muscat Daily) Audi presented a truly special show car at the Geneva Motor Show.
The Audi TT quattro sport concept embodies the dynamic potential of the new Audi TT in its purest form.
Its two-litre TFSI supplies 420hp, which the car puts on the road via the quattro all-wheel drive. ''With our Audi TT quattro sport concept show car, we wanted to demonstrate what the new TT's technology can do if you take it a step further,'' said Prof. Dr Ulrich Hackenberg, board member for Technical Development. ''This car is designed for racing “ an extreme driving machine for the motorsports enthusiasts among our customers.''
The engine in the Audi TT quattro sport concept makes a powerful statement. The 2.0 TFSI has a power output of 420 hp at 6,700 rpm “ a new benchmark in the two-litre category. Its specific output is 210 hp per litre of displacement “ that's more than even 2001's victorious Le Mans R18 racing car, which was the first time Audi combined turbocharging with FSI direct gasoline injection.
The four-cylinder engine has 450 Nm of torque available in the engine speed range from 2,400 to 6,300 rpm. with over 300 Nm already available at only 1,900 revs. At a curb weight of 1,344kg (without driver), the Audi TT quattro sport concept is an athlete in peak condition. Each hp supplied by the two-litre FSI, which itself weighs under 150 kilograms, needs to shift less than 3.2kg.
The four-cylinder engine catapults the show car from 0 to 100 km/h in just 3.7 seconds. Dr Stefan Knirsch, head of powertrain development, said, ''This high-performance power unit is an impressive demonstration of the power reserves available in our EA888 engine range. This power unit has received numerous awards all over the world and it already lives up to its claim in many Audi sporty models. In the TT quattro sport concept, it demonstrates its full power potential. The 35 years of experience we've gained in the field of turbocharging are manifested in this engine's unique combination of maximum performance, dynamism, and fuel efficiency.''
The engine is once again based on the successful EA888 technologies such as the Audi valvelift system (AVS) variable valve timing, dual camshaft adjustment, and dual injection system (FSI plus MPI). A wide range of modifications are featured, including special aluminium pistons with integrated cooling channels and an ultra-highstrength forged steel crankshaft.
The EA888's familiar, highly compact thin-wall cylinder crankcase is here made of a highstrength cast alloy. The also newly developed exhaust-gas turbocharger features optimized mixed-flow technology and produces up to 1.8 bar of charge p
