Mercedes-Benz SLR McLaren Coupe
The Mercedes-Benz SLR McLaren was the result of the most ambitious collaboration in automotive history — Mercedes-Benz, the grand marque of German engineering, and McLaren, the Formula 1 constructors, joining forces to build a supercar. The result was a 208-mph grand touring missile that combined Mercedes' engine expertise with McLaren's carbon fiber and chassis knowledge.
The SLR was powered by the M155 engine — a 5.4-liter supercharged V8 derived from AMG's M113 engine but extensively modified with a Lysholm-type twin-screw supercharger, dry sump lubrication, and hand assembly. Output was 617 hp and a massive 575 lb-ft of torque — enough to propel the car from 0-60 mph in 3.4 seconds and to a top speed of 208 mph.
The body was constructed primarily of carbon fiber, manufactured at McLaren's Technology Centre in Woking, England. The distinctive long hood (housing the front-mid-mounted engine) evoked Mercedes' racing Silver Arrows, while the butterfly doors provided dramatic access to the cockpit. An electrohydraulic air brake (rear spoiler that angled upward under braking) added both function and theatre.
The SLR was positioned as a grand tourer rather than a track weapon. The interior was trimmed in the finest leather and carbon fiber, the boot was large enough for a weekend's luggage, and the ride was surprisingly compliant. It was a car for crossing continents at incredible speed in complete comfort.
Variants included the SLR 722 Edition (2007, 650 hp, named after Stirling Moss's race number), the SLR Roadster (2008), the SLR Stirling Moss (2009, 75 units, roofless and windshield-less speedster), and the SLR 722 GT (race car).
The SLR's reputation has evolved. Initially criticized as being too heavy and too soft compared to the Ferrari Enzo, it's now recognized as one of the great modern grand tourers — a car that combines extraordinary performance with effortless usability.
The SLR is a complex car requiring specialist maintenance. The supercharged M155 engine is AMG-derived and relatively reliable, but service costs are extreme. The carbon fiber body is expensive to repair if damaged. The 5-speed automatic gearbox is the car's weak point — it's adequate but feels dated compared to modern dual-clutch units. The air brake mechanism, butterfly door hinges, and electrohydraulic systems all require specialist attention. The 722 Edition is the most desirable for enthusiasts. Service history and low mileage are essential for investment-grade cars.
SLR Coupe: approximately 2,157 units (2004-09). SLR 722 Edition: 150. SLR Roadster: approximately 1,025. SLR 722 Roadster: approximately 150. SLR Stirling Moss: 75 (most expensive SLR at $1.2 million). Total all SLR variants: approximately 3,557. All cars were hand-built at McLaren's Woking facility.
