sports five-cylinder petrol engines have a long history of Audi. The most famous is probably the 2.1 liter turbocharged engine in the Audi quattro. The first version, launched in 1980, offered an impressive 147 kW (200 hp). Audi Sport Quattro and 1984, directly inspired by motor sport, has delivered an enormous 225 kilowatts (306 hp). For 25 years, turbo and quattro was a dynamic formula for success.
Audi has chosen to use this recipe. Designed from the ground, five-cylinder turbo engine combines direct fuel injection to raise the FSI Audi TT RS high-performance sports car. TFSI produces 250 kW (340 hp), the transition from 2480 cc (151.34 cu): a special power of 100.8 kW (137.1 hp) per liter.
Power to weight ratio is excellent. In the case of the Coupé, which weighs just 1,450 kilograms (3,196.70 pounds), power to weight ratio is only 4.3 kg / hp. Audi TT RS Roadster weighs 1,510 kilograms (3,328.98 pounds) and power to weight ratio 4.4 kg / hp - thanks to the ultra-lightweight aluminum frame and largely built around the principles of Audi Space Frame.
The Audi TT RS coupe rockets from 0 to 100 km / h (0 to 62.14 km / h) in 4.6 seconds, the Audi TT RS Roadster needs only a tenth of a second. The speed limit of 250 kmh (155.34 mph) is the official figure of the two versions as an option, Audi can increase to 280 km / h (173.98 mph).
Almost more impressive is the attraction aggressive. Torque of 450 Nm (331.90 Nm) is available between 1600 and 5300 rpm. In addition, the Audi TT RS passes without the slightest effort. Last but not least, the engine makes the skin of the passengers' tingling again and again thanks to the rapid and effective response, inspiring free-roaming nature, tailpipes and his sore unequivocal: the five-cylinder Audi classical music!

And weighing just 183 kilograms (403.45 pounds), also set a record. The casing is made of vermicular graphite cast. This high tech material attaches the greatest strength with low weight, was also used for more Audi TDI engines. Perfectly located reinforcements improve the capacity for load. Light cylinder head, pistons and connecting rods are light weight and high strength.
The ultra-powerful engine with five cylinders is extremely fuel efficient, requiring an average of only 9.2 l/100 km [25.57 mpg] in terms Coupé (cabriolet: 9.5 l/100 km [24, 76 mpg]). switchable flaps in the intake manifold air mixture entering a configuration calculated. Injected with a pressure up to 120 bar common rail system, the gasoline intense vortices in the combustion chamber - which in turn cools the walls. This then facilitates a 10.0:1 compression ratio of which is very high for a turbo engine. The two adjustable camshafts, driven by chains, also to improve the charging efficiency of air-fuel mixture.
The turbocharger generates high as 1.2 bar boost pressure. The intercooler, fully supplied with air at the bottom of the inner grid, reducing the temperature of air compressed by over 80 percent at full load.
When the standard Audi TT RS Sport driver presses the button on the center tunnel, the flap installed on the left exhaust pipe exhaust system makes the noise even stronger and more powerful at the same time, increasing engine responsiveness. The optional sport exhaust system is available in matte black exhaust emissions and sound flip.

The Audi TT RS has quattro permanent all standard equipment. His heart is in the rear, an electronic control, hydraulic clutch blinds. If the situation requires it, the clutch directs most of the input torque of the front wheels to the rear wheels.
Within milliseconds, a powerful electric pump with battery weighs together through a hydraulic clutch. Four added power line falls at a constant speed, before the 'common propeller shaft and a compact rear axle differential - both are heavy elements.
Subsidies quattro, Audi TT RS outstanding fascinating dynamics and excellent stability. Dissolution of rural areas or a few laps on a circuit to allow top management to shine.

So that the heat dissipates quickly in front of all season tires are perforated. They in turn are connected to the cable pin aluminum brake discs, which are surrounded by black four piston aluminum calipers and features a logo-RS.
The Electronic Stabilization Program (ESP) can be disabled completely or partially. In Sport mode, the engine does not intervene to control traction and braking even later than usual. In the second mode ESP is completely deactivated.
Power Face The Exterior
Slightly 4.20 meters (13.78 feet) long, firm and compact Audi TT RS notes of his explosive power of first contact. Spoiler restricts the retailer, which is reminiscent of a racing car.
