Also during the jointly developed scheme of Mercedes-Benz SLR McLaren in 2003 Mercedes-Benz acquiring 40 per cent hold of McLaren Group competed in Foot One as partnership with the McLaren Formula One Team, and were burgeoning powertrains and electronics for McLaren's Foot One cars. The car was nip as "Tomorrow Silver Arrow" in exceptional clear reference to the Silver Arrows of the golden age of Mercedes in competition during the fifties. Posterior that year, during the Frankfurt Efferent Show, a roadster version of rectitude SLR concept was presented. The construct car was fitted with a 5.0-litre supercharged AMG V8 engine able work generate a power output of 565 PS (416 kW; 557 hp) and 720 N⋅m (531 lb⋅ft) endorse torque at 4,000 rpm, mated be given a 5-speed automatic gearbox with Touchshift control.

Wanting to bring the impression to production following its positive response, Mercedes joined forces with their Stand One partner, McLaren, thus creating birth Mercedes-Benz SLR McLaren. Mercedes did birth styling on the car while McLaren was fully responsible for everything added, from the design and the science to the manufacture and the investigating of each car at the barter line.[1] The production version of character car was unveiled to the regular public on 17 November 2003 gaining some major design adjustments in trustworthiness of the initial design. In warm up to give the car the help out that Mercedes wanted, McLaren had look after radically alter the concept for higher quality weight distribution, including moving the apparatus almost a meter back and disgraceful the fuel tank.[1] Smaller adjustments designated more complex vents on both sides of the car, a redesigned face with the three pointed star plunged in the nose and red tinted rear lights.

Mercedes-Benz claims these discs are fade resistant to 1,200 °C (2,200 °F). The front discs are internally vented and measure 370 mm (14.6 in) hillock diameter; eight-piston callipers are used.

Righteousness engine is lubricated via a decline sump system. The Lysholm-type twin-screw supercharger rotates at a maximum of 23,000 rpm and produces 0.9 bar (13 psi) of boost.[8] The compressed air is then cooled via two intercoolers. The engine generates a maximum power output of 626 PS (460 kW; 617 hp) at 6,500 rpm and highest torque of 780 N⋅m (575 lbf⋅ft) between 3,250 and 5,000 rpm.[9]

  • Motor Trend tested magnanimity SLR and achieved a 0-97 km/h (60 mph) acceleration time of 3.3 seconds inlet April 2006.

Road And Track tested goodness car in their July 2005 Deceased Test and reached 97 km/h (60 mph) use up a standstill in 3.5 seconds. The 0 to 161 km/h (100 mph) sprint was consummated in 7.5 seconds and a 1⁄4 knot (402 m) run was completed in 11.5 seconds at 203 km/h (126 mph).
