The common will of winning in the formula 1 bands together McLaren and DaimlerChrysler. Besides, DaimlerChrysler holds 40% of stocks in McLaren. The cigarette company West is their main sponsor since 1997, introducing the typical color of the racing cars, including the typical silver color which is also historically interesting, because of Daimler's racing history. This is also the color of the first SLR McLaren which is planned after 1999 because of the successes in the brand world championship and designer world championship. On top you may also see a black 2007 model.

The 'SLR' relates back to the famous racing version of the 300 SL. At that time the engine featured eight cylinders in line, this engine has them in a V shape. However, the double charged engine has very few in common with a real F1 engine. The nose does bring up reminiscences with the formula 1 and the extensive use of coal fiber material.

It takes until 2004 for the production of the limited edition to start and it is still not finished in 2007. The design and construction take place exclusively in Great Britain, supervised by Gordon Murray who is also responsible for the formula racing cars. Interesting are its upwards opening doors, another reminiscence of the 300 SL. The Mercedes star on the nose is assigned another task: through its openings air is sucked in for the combustion in the engine.

A pity that the SLK has a V8 engine, at which Daimler Benz wants to try out, whether it does not even go with less effort. An overhead camshaft per cylinder bank and two intake and one outlet valve should actually also be sufficient. One did not stand it.
