Mercedes-Benz SL has been produced for the first time almost entirely from aluminium and weighs up to 140 kilograms less than its predecessor. Other new features include the unique Frontbass system, which turns the luxury sports car into a concert hall regardless of whether the top is open or closed, and the highly efficient adaptive windscreen wipe/wash system MAGIC VISION CONTROL; it supplies water from the wiper blade as required and depending on the direction of wipe.
The new V8 in the SL 500 develops 320 kW (435 hp) from its displacement of 4663 cc and thus around 12 percent more than its predecessor despite some 0.8 litres less displacement. The fuel consumption has been reduced by up to 22 percent. At the same time, the torque has increased from 530 Nm to 700 Nm – a gain of 32 percent. Although the displacement remains the same at 3499 cc, the new V6 engine in the new SL 350 develops 225 kW (306 hp) and delivers 370 Nm of torque. It uses just 6.8 litres of fuel per 100 kilometres, making it almost 30 percent more economical than its predecessor. Both engine variants come with a standard-fit ECO start/stop function. The 7G-TRONIC PLUS automatic transmission, which has been optimised in relation to fuel consumption and comfort, also contributes to the exemplary, low fuel consumption. The fuel economy of the BlueDIRECT engines takes nothing away from the roadster’s raciness. Quite the contrary: the SL 350 accelerates from 0 to 100 km/h in 5.9 seconds, making it three tenths of a second faster than its predecessor. The SL 500 takes just 4.6 seconds – eight tenths less than the previous SL 500.
