Thanks to the combination of 3.0-litre V6 biturbo engine and 9G-TRONIC sports transmission, the 36 horsepower (270 kW) roadster consumes just 7.8 litres of fuel per 100 kilometres (NEDC, combined). Consequently, the open-top two-seater not only uses 0.6 l/100 km less than its predecessor, the SLK 55 with V8 naturally aspirated engine, but is also the most efficient six-cylinder performance roadster on the market. The specially developed suspension and model-specific mountings for engine and rear-axle gear unit are designed for high lateral acceleration and low roll. Even greater driving dynamics is optionally available with the AMG Ride Control suspension with adaptive adjustable damping and the Handling package with mechanical limited-slip differential on the rear axle. The 3.0-litre V6 biturbo engine offers impressive performance with its 367 hp (270 kW) maximum power and peak torque of 520 Nm: sprinting from rest to 100 km/h in 4.7 seconds, its top speed is electronically limited at 250 km/h. The key factors behind the snappy, agile roadster driving experience are the newly developed front and rear axles, new engine/rear-axle gear unit mountings, stiff elastokinematics and highly precise steering. Even greater transverse dynamics is made possible by the optional Handling package with mechanical limited-slip differential on the rear axle. The standard-fit sports exhaust system comes with two automatically map-controlled exhaust flaps. In the "Eco" and "Comfort" transmission modes, the flaps remain closed most of the time, this resulting in an acoustically restrained note from the six-cylinder biturbo engine. In the "Sport" and "Sport +" modes, the exhaust flaps open earlier and more spontaneously, especially if the driver prefers a dynamic driving style. The effect: the typical, emotively appealing AMG engine sound. The statutory noise prevention limits are met in all transmission modes.
