2007 Mercedes-Benz SLR McLaren (R199) Roadster Dimensions, Size & Specs

The curb weight of the Mercedes-Benz SLR McLaren (R199) Roadster is 1750 kg (3858 lbs), which represents the vehicle's weight including standard equipment and fluids but excluding passengers and cargo. Its maximum weight, which is the highest permissible total weight including passengers and cargo, is 1980 kg (4365 lbs). This balance allows for both high performance and stability.

The Mercedes-Benz SLR McLaren (R199) Roadster offers a luggage capacity of 204 liters (about 7.2 cubic feet). While this is modest compared to typical sedans or SUVs, it is fairly practical for a high-performance roadster, suitable for small bags or a set of luggage for weekend trips, but not large items or heavy cargo.

This roadster is equipped with a variety of rim sizes: 11.5J x 18 inches, 9J x 18 inches, 11.5J x 19 inches, and 9J x 19 inches. Corresponding tire sizes include 295/35 R18, 245/40 R18, 295/30 R19, and 255/35 R19. These wide rims and tires contribute to superior grip and handling performance, essential for a sports car of this caliber.

The Mercedes-Benz SLR McLaren Roadster, with a length of 4656 mm (183.3 inches), width of 1908 mm (75.1 inches), and height of 1281 mm (50.4 inches), should fit comfortably in a standard garage. Typical garages range around 2400 mm (94.5 inches) wide and 4800 mm (189 inches) deep, providing adequate clearance. However, the owner should consider additional space for opening doors and maneuvering, especially given its wide profile.

The SLR McLaren (R199) Roadster was the first and only generation of this model, thus it does not have a predecessor for direct size comparison. As a specialized supercar, it was designed from the ground up with distinctive dimensions emphasizing performance and style, unlike other Mercedes-Benz models that evolved incrementally within their classes.

When compared to rivals like the Ferrari F430 Spider or Aston Martin V8 Vantage Roadster, the Mercedes-Benz SLR McLaren Roadster is relatively longer and wider. Its length of 4656 mm (183.3 inches) and width of 1908 mm (75.1 inches) provide a commanding road presence and stability. While its height of 1281 mm (50.4 inches) is low to the ground, enhancing aerodynamics, the curb weight at 1750 kg (3858 lbs) is heavier, reflecting its grand tourer characteristics alongside supercar performance.

The aerodynamic dimensions—length: 4656 mm (183.3 inches), width: 1908 mm (75.1 inches), and especially the low height of 1281 mm (50.4 inches)—contribute to excellent high-speed stability and cornering ability. The wide stance and low center of gravity enhance grip and handling, while the somewhat substantial curb weight at 1750 kg (3858 lbs) balances performance with luxury features, resulting in a compliant yet exhilarating driving experience.

Although primarily a high-performance roadster focused on speed and style, the SLR McLaren Roadster offers modest interior space suitable for two occupants. With a luggage capacity of 204 liters (7.2 cubic feet), it can accommodate small bags or a light weekend's worth of gear, making it surprisingly reasonable for occasional longer trips. However, its low-slung design and compact dimensions prioritize sportiness over everyday practicality.

While both versions share the same basic platform and dimensions—length 4656 mm (183.3 inches), width 1908 mm (75.1 inches), and height 1281 mm (50.4 inches)—the roadster features a retractable soft top that adds slight complexity in construction but does not significantly alter its size. The roadster’s roofless design offers an open-air experience at the expense of marginally increased weight versus the coupe. Overall, both versions have similar driving dynamics with the roadster emphasizing the pleasure of open-top motoring.
