Audi TT RS vs BMW Z4

Audi TT RS


Audi is once again producing a five-cylinder motor - and a very special one at that. Arriving at dealers this summer, the Audi TT RS has a turbocharged 2. 5-liter motor with direct gasoline injection; it produces 250 Kw (340 bhp) and 450 Nm (331. 90 lb. -ft. ) of torque. The blazing five-cylinder motor allows the Audi TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the motor makes the compact Audi TT RS a top-notch sports vehicle - available as a coupé or roadster.

Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2. 1-liter motor in the Audi quattro. The first version, which was launched in 1980, provided an cool 147 Kw (200 bhp). And the Audi Sport quattro from 1984, directly inspired by motorsport, provided a whopping 225 Kw (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.

Audi has resumed using this recipe. Developed from scratch, the five-cylinder motor features a turbocharger with FSI direct gasoline injection to elevate the Audi TT RS to a high-performance sports vehicle. The TFSI provides 250 Kw (340 bhp) from a displacement of 2480, cc (151. 34 cu in): a specific output of 100. 8 Kw (137. 1 bhp) per liter.

The power-to-weight ratio is also impressive. In the case of the Coupé, which weighs in at a mere 1450, kilograms (3196,. 70 pounds), the power-to-weight ratio is just 4. 3 kilograms per bhp. The Audi TT RS Roadster has a weight of 1510, kilograms (3328,. 98 pounds) and a power-to-weight ratio of 4. 4 kilograms per bhp - due to its extremely lightweight and largely aluminum body constructed as per the Audi Room Frame principle.
Combining classic proportions with modern sportiness, the new BMW Z4 has reached the top of its sphere segment almost overnight. And now this charismatic roadster is entering a new dimension in driving dynamics, the new BMW Z4 Sdrive35is product an even higher traditional of performance ensured both by the modified straight-six performance unit with BMW Twin Turbo Technology and High Precision Injection, on the one hand, and by BMW's seven-speed Sport Automatic with double clutch operation and the M Sports Suite including the adaptive M Suspension likewise featured as traditional, on the other. Appropriate optimisation in motor technology increases maximum output of the 3. 0-litre performance unit to 250 Kw/340 hp. Peak torque is 450 Newton-metres/332 lb-ft, increasing briefly with the Overboost function to 500 Newton-metres/369 lb-ft. The impressive performance and performance of the BMW Z4 Sdrive35is is expressed in particular by the significant increase in pulling performance and muscle to be clearly experienced in all situations. In conjunction with seven-speed Sport Automatic featuring double clutch operation, this new top-of-the-range.

At 9. 0litres/100 kilometres (equal to 26. 1 mpg US) and 210 grams in the EU test cycle, fuel consumption and CO2 emissions are the same as on the BMW Z4 Sdrive35i with Sport Automatic.

The BMW Z4 Sdrive35is is making its world debut at the 2010 North American International Auto Show (NAIAS) in Detroit. And parallel to the sphere release of this high-performance roadster in spring 2010, the M Sports Suite is being presented for all further versions of the BMW Z4.
