Engine choices: SLK55: The new SLK 55 AMG now sets a new benchmark in terms of power (265 kW/360 hp), torque (510 newton metres) and acceleration (0-100 km/h: 4.9 seconds). The V8 power unit is twinned as standard with the recently developed 7G-TRONIC seven-speed automatic transmission controlled by the driver using gearshift buttons on the steering wheel. SLK 350: Mercedes-Benz has developed a new six-cylinder engine with around 25 percent more power (200 kW/272 hp) and 13 percent more torque (350 newton metres) for the SLK 350. The four-valve engine is one of the most powerful V6 units in its displacement class and its sporting character can be clearly distinguished by its powerful, vibrant engine note. Maximum torque is available from an engine speed of just 2400 rpm and remains constant across a wide rev band extending up to 5000 rpm. This allows the car to be accelerated hard and permits rapid bursts of power. From a standing start, the SLK 350 reaches 100 km/h in just 5.6 seconds (with the 7G-TRONIC: 5.5 seconds) and accelerates from 60 to 120 km/h in 8.7 seconds (with the 7G-TRONIC: 5.1 seconds). Also there will be an SLK200 Kompressor with 163hp. Check out Germancarfans for the full release.
