Mercedes shows lightweight, 400-hp SLK 55 AMG
Affalterbach, Germany – The Mercedes-Benz SLK 55 AMG two-seater sports car is now even sportier, says Mercedes-Benz. With an AMG 5.5-litre V8 engine enhanced to 400 horsepower, numerous lightweight construction components, a carbon fibre hardtop, 19-inch AMG forged wheels, AMG height-adjustable torsion sports suspension and AMG high-performance composite brake system, the SLK 55 AMG has a power to weight ratio improved from 4.3 to 3.7 kg/hp.
The front of the car has a restyled AMG front apron with large air intakes which supply the additional transmission oil cooler and the high-performance steering gear oil cooler with sufficient fresh air. New side air outlets of black carbon ensure an effective flow through of the larger engine oil cooler. The front fenders which are now wider are made of the ultra-light carbon-fibre-reinforced-plastic (CRP) and have black out-lined air outlets.
The non-retractable hardtop of the two-seater is also made of CRP. By discarding the vario roof and the complete roof hydraulics, Mercedes was able to lower the centre of gravity, and reduce weight. The new SLK 55 AMG is 45 kg lighter than the basic vehicle.
