The Audi TT Coupe Quattro 2.0 TDI and the Audi TT Roadster 2.0 TDI quattro is the first production sports car with a diesel engine as a drive.
A connection that convinced: The new two-litre four-cylinder provides 125 kW (170 hp) and 350 Nm output torque for dynamic jacking. It consumes the TT Coupe and The TT Roadster in the Middle only about 5.3 liters or 5.5 liters of fuel per 100 km - an unrivalled low value in the sports car segment.
Since its 1989 debut, the TDI engines of the brand with the four ring the way for the successful efficiency technology in the world and also a trendsetter for the entire automotive industry. The triumph of diesel racing car Audi R10 TDI at the 24 Hours of Le Mans and in the American Le Mans Series has the potential of high technology impressively demonstrated.
Also in the series fascinate the diesel engine from Audi, with its dynamics - now even in a sports car. The TT Coupe Quattro 2.0 TDI with the speed up at 7.5 seconds from zero to 100 km / h and reaches 226 km / h top.
The Audi TT Roadster, with the permanent all-wheel drive Quattro equipped need for the standard sprint only about a tenth of a second longer, his head is 223 km / h. With consumption levels by 5.5 litres per 100 km - according to a CO2 emissions of only 144 g / km - shipping both outstanding examples of the success of the strategy of efficiency Audi.
The new four-cylinder TDI with its 1,968 cm 3 Displacement completely convincing interprets the qualities of TDI concept to a new level. The two-liter with its two camshafts builds the great strengths of its predecessor, most of the diesel engine in the world, continues - driving pleasure, economy and culture course. The system pressure in the plant is located at 1800 bar, the resulting possible fine atomization of the fuel stands for a precise, highly efficient combustion.
The turbocharger is also part of a new generation. It operates torque for rapid design with adjustable guide vanes. The intake manifold sitting swirl flaps and electric motors to control their position to the air intake of each load and speed. On the engine, the piston in its geometry modified and the tooth belt drive acoustically revised.
As with the previous two aggregate compensation reduce the vibration waves in the crank drive. The raw emissions of nitrogen oxides drop dramatically. The 2.0 TDI already met the limits of the future Euro 5 norm.Dynamic: The driving performance
The 2.0 TDI in the Audi TT Coupe and Audi TT roadster is 125 kW (170 hp) at 4,200 1/min and 1,750 to 2,500 1/min a rich torque of 350 Nm on the crank shaft. It works quietly and vibration, he pulls out of the cellar speed out by weighty and depends closely on the gas.
The Audi TT Coupe Quattro 2.0 TDI does the sprint from zero to 100 km / h in only 7.5 seconds. Only at 226 km / h ceases to be boring. The TT Roadster accelerates in 7.7 seconds on country roads and on pace to 223 km / h.
In the Middle consume the first two diesel sports car in the world only 5.3 or 5.5 liters of fuel per 100 km - in accordance with an output of only 140 or 144 grams CO2/km. To set a benchmark in the field of sports cars an absolute quantum leap. With the TDI engine in the TT series, Audi its leading role in the diesel sector once again demonstrated.
In the spirit of sporting performance consistently Audi combines his two self-igniter sports car with six-speed manual gearboxes, based on short distances quickly, easily and accurately, and to turn a high degree of efficiency. Their housing is made of the lightweight high-tech materials magnesium cast.
Given the high torques are two new Audi TT variants of the permanent all-wheel drive as standard with Quattro. His heart is an electronically controlled and hydraulically operated clutch slats for the benefit of the distribution of weight in the stern sits. These clutch distributes the engine power normally 85 percent on the front axle and 15 percent to the rear axle, in extreme cases can be up to 100 percent on an axis guide.
To effectiveness of the brand strategy includes the consequent reduction of the weight. Both sports cars built very easily - 2 - 2-seater TT coupe brings empty only about 1,370 kilogram on the scales, while two TT roadster with its fabric, there are about 1415 kilograms. The reason for this is the innovative hybrid design of the body, the Audi has developed - in the front area is the construction of aluminum in space-frame construction, in the rear of steel are used. This solution guarantees maximum rigidity and an ideal distribution of the axle loads.
The Audi TT coupe and the TT Roadster are dynamic, emotional sports cars. Like their predecessors fascinated her powerful design, interior space, its momentum flowing. The cockpit cited the classic circular motif on several occasions, the sports steering wheel with a flattened bottom circle is perfectly in the hand. The sports seats are mounted low, they convey an athletic position and solid lateral support. When coupe can be lean seats to turn down the fund, thereby increasing the luggage space from 290 to 700 litres of volume. The roadster has a luggage capacity of 250 litres.
Even the sports chassis offers the highest dynamic. The front wheel suspension, an axle made of aluminum applications, has a wide track of 1,572 millimetres. A directly translated, high-precision steering rack connects the driver to work closely with the street. Their servo support decreases with increasing speed. Generates will not by a hydraulic pump, but more efficiently, by electromechanical actuator.
In the four-handlebar rear axle, the coil springs and shock absorbers structurally separated. The three arms per wheel, however, are stiff connected to the lateral forces accurately in the body.
The Audi TT Coupe Quattro 2.0 TDI and the Audi TT Roadster 2.0 TDI Quattro roll on 16-inch wheels made of aluminum castings in which tires the size 225/55 R 16 are raised. Behind them sit large disc brakes, the high friction surfaces.
The standard equipment for the two new variants TT reflects the sporty character and the fine style of the series. The interior decor shines gray deposits and various components in aluminum optics. The - when TT Coupe standard - automatic climate controls the heating and ventilation depending on the sunshine state. The driver information system and the audio system "chorus" complete the standard equipment.
Among the extras is a wide range of high-tech options - such electrically adjustable front seats, the dynamic cornering light adaptive light, two navigation systems, which operate at the MMI-oriented approach of Audi, and an advanced generation of audio devices.
