Safety: newly developed protection system with adaptive airbags
An ultramodern design procedure, a 40 % increase in the use of high-tensile steel alloys and many other additional measures allow the new SLK-Class to surpass the high safety standards set by its predecessor. The occupant protection systems respond to the prevailing situation: for the first time, Mercedes-Benz is using adaptive airbags in this model range, which deploy in two stages depending on the severity of the accident.
The belt force limiters, now standard equipment, also function in two stages and adjust to the severity of the accident. In instances of side impact, recently developed head-thorax airbags spring into action and protect the occupants’ head and upper body. A special sensor also triggers the side airbags and both belt tensioners in the event of the vehicle rolling over. Robust steel tubes in the A-pillars and solid roll-over bars behind the seats offer additional protection in accidents of this kind.
Engines: Up to 25 per cent more performance with reduced fuel consumption
The range of engines available with the new SLK-Class is also unique for this market sector. Mercedes-Benz is the first carmaker in this segment to respond with an eight-cylinder engine to the wishes of performance-minded car drivers. The new SLK 55 AMG now sets a new benchmark in terms of power (265 kW/360 hp), torque (510 Nm) 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.
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 Nm) 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).
This is the first time that Mercedes-Benz has ever produced a V6 engine with variable camshaft control on intake and exhaust sides. The outcome is enhanced performance and torque combined with improved fuel economy. A two-stage intake manifold, "tumble" flaps in the intake ducts and an intelligent heat management system add to the technical distinguishing features of this new six-cylinder engine. When combined with the option of a seven-speed automatic transmission, the new SLK 350 only consumes a meagre 9.9 litres of fuel over a distance of 100 kilometres (NEDC total consumption figures) and therefore, despite a significant increase in performance figures, still manages to be some five percent more fuel-efficient than the previous SLK six-cylinder engine with a five-speed automatic transmission.
