Mercedes-benz SLR Used Parts Online

The Mercedes-Benz SLR McLaren is an Anglo German super car jointly developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England. Daimler AG, owner of Mercedes-Benz, also owns 40% of the McLaren Group. Due to the presence of the automatic gear box, front mid engined arrangement and its driving characteristics lead some commentators to classify the SLR McLaren as a GT whose rivals can be considered to be e.g. the Aston Martin V12 Vanquish and Ferrari 599 GTB Fiorano. The Mercedes-Benz SLR McLaren is inspired by the Mercedes-Benz 300 SLR of 1955, based on the W196 F1 car, yet named after the road going 300SL Gullwing. On 4 April 2008, Mercedes announced they will cease production of the SLR. The last of the coupes rolled off the production line at the end of 2007 and the roadster version is due to be discontinued in early 2009. The SLR features Sensotronic, a type of brake by wire system. The brake discs are carbon ceramic and provide better stopping power and fade resistance than steel discs when operating under ideal working temperature. Mercedes-Benz claims these discs are fade resistant to 1,200 °C (2,200 °F). The front discs are internally vented and 370 mm (14.6 in) in diameter. 8 piston calipers are used. Rear discs are 360 mm (14.2 in) in diameter with 4 piston calipers. During wet conditions the calipers automatically skim the surface of the discs to keep them dry.

The SLR features active aerodynamics; there is a spoiler mounted on the rear integral air brake flap. The spoiler increases downforce depending on its angle of elevation (angle of attack). At speeds above 95 km/h (59 mph) the spoiler brake automatically raises to 10 degrees, when demanded via the driver's switch, the elevation can be increased to 30 degrees (35 in 722 version) for increased rear downforce, at the cost of increased steady state drag. The SLR sports a 232 kg (511 lb) hand built 5.4-litre (5,439 cc (332 cu in)), supercharged, all aluminium, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 millimetre (3.82 in) and 92 millimeters (3.62 in), respectively. The Lysholm type twin screw supercharger rotates at 23000 revolutions per minute and produces 0.9 bar(13 psi) of boost. The compressed air is then cooled via two intercoolers. The engine generates a maximum power of 626 bhp at 6500 revolutions per minute and a maximum torque of 780 N-m (575 lb-ft) at 3250 revolutions per minute. Unlike most of its contemporaries, its engine is front mid mounted. McLaren took the original concept car designed by Mercedes and moved the engine 1 metre (39.4 in) behind the front bumper, and around 50 centimetres (19.7 in) behind the front axle. They also optimized the design of the center firewall.
