Mercedes-Benz SLR McLaren — TIMING CHAIN OR BELT?


| Home / Mercedes-Benz / List of Mercedes SLR Models without Timing Belt

The Mercedes-Benz SLR McLaren is a high-performance Grand Touring car. It was developed between Mercedes-Benz (which was within the DaimlerChrysler conglomerate at the time) and McLaren Automotive. The SLR McLaren was first introduced in 2003 and was produced until 2010. A little over 2,000 units were put into circulation, and only one generation existed.

One of the most outstanding features of the SLR McLaren is its sleek, aerodynamic design, developed with the help of F1 engineers. The car is powered by a 5.4-liter supercharged V8 engine that produces a whopping 617 hp. In addition to its impressive performance, the SLR McLaren also boasts a luxurious interior, with leather seats, as well as a dihedral door opening, which is a trademark of the German brand in this type of flagship models.

Despite its impressive specifications, the Mercedes SLR McLaren also received critics. Some car enthusiasts beeived that it was too heavy and not as agile as other high-performance sports cars, while others complained about the high price tag. Even so, the SLR McLaren remains a highly sought-after vehicle by collectors and motorheads due to its rarity and iconic status.

Mercedes first started working on the SLR McLaren in 1998. It hit the market with two body styles available: Coupe and Roadster. Years later, the brand released a limited edition of 722 units with a supercharged engine of 722 hp. In addition, the German brand presented a concept in 2009 at the North American Motor Show called Mercedes SLR McLaren Stirling Moss.

Mercedes SLR McLaren Edition (2010)

More than a year after the SLR ceased to be sold, McLaren Special Operations (MSO) announced a custom program for the SLR in December 2010. The McLaren Edition is based on all SLR models (with the exception of the Stirling Moss), and comes with updated exterior bodywork (such as front and rear bumpers, grilles, upper housings, side grilles and rear diffusers), interior parts and new titanium sports exhausts. No two cars were the same, since modifications were made exactly to the owner’s specifications. A total of 25 units were customized for more than 200,000 euros, making these cars even more coveted by collectors.
