2006 Mercedes-Benz R-class Long (V251) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz R-class Long (V251) ranges from 2175 kg to 2385 kg (approximately 4797 to 5257 pounds), which accounts for the vehicle's weight without occupants or cargo but with all necessary operating consumables. The maximum permissible weight, which includes passengers, cargo, and fuel, varies between 2810 kg and 2950 kg (around 6197 to 6503 pounds). This weight range indicates the robust build quality and capability for carrying substantial loads, characteristic of a large luxury station wagon.

The Mercedes-Benz R-class Long (V251) offers a ground clearance of 148 mm (approximately 5.8 inches), providing reasonable clearance over uneven road surfaces and retaining a low-slung sporty profile typical of luxury station wagons. Its roof load capacity is rated at 100 kg (about 220 pounds). This means it can support roof racks or cargo carriers within this weight limit, allowing for extra luggage or sporting equipment, ideal for family outings or long trips.

The luggage capacity of the Mercedes-Benz R-class Long (V251) is 550 liters (about 19.4 cubic feet) with all rear seats in use, offering enough space for everyday luggage needs such as shopping, groceries, or sport gear. When the rear seats are folded down, the cargo capacity expands dramatically to a range between 1950 liters and 3215 liters (approximately 68.9 to 113.5 cubic feet), making this vehicle highly versatile for transporting large items or accommodating more considerable family travel with bulky gear or furniture.

Most standard residential garages typically have dimensions around 2500 mm (98 inches) in width and 5000 mm (197 inches) in depth, with heights commonly around 2100-2200 mm (83-87 inches). The Mercedes-Benz R-class Long (V251) measures up to 5165 mm (203.5 inches) in length, 1922 mm (75.6 inches) in width, and up to 1674 mm (65.9 inches) in height. Its width and height are within typical garage limits, but due to the length slightly exceeding 5 meters, parking can be tight or require precise maneuvering in standard garages. It comfortably fits width and height-wise but may be a tight fit length-wise, especially in smaller or older garages.

The predecessor to the R-class Long (V251) was the original R-class (W251) launched in 2005, generally slightly shorter and with less expansive rear passenger and cargo space. The V251 Long version increased length marginally to enhance interior flexibility, particularly for rear legroom and cargo capacity. Overall, the V251 Long is longer by a few hundred millimeters compared to the standard predecessor version, maintaining a similar width and height but offering improved internal comfort and storage space, which was a key selling point distinguishing it within the series.

Compared to other luxury station wagons produced around the same period, such as the Audi A6 Avant or Volvo V70, the Mercedes-Benz R-class Long (V251) is generally larger in length and height, reflecting its unique positioning as a large multi-purpose luxury vehicle rather than just a wagon. Its length of over 5.1 meters surpasses many competitors, offering additional interior passenger and cargo space. The width at 1922 mm and generous luggage capacity when seats are folded also ideate a more spacious cabin environment, making it ideal for families who prefer luxury combined with multi-functionality.

The Mercedes-Benz R-class Long (V251) comes equipped with various rim sizes including 17, 18, 19, and 20 inches, with corresponding tire sizes like 235/65 R17, 255/55 R18, 255/55 R19, and 265/45 R20. Larger rims and lower-profile tires usually enhance sporty handling and aesthetics but may slightly reduce ride comfort due to stiffer sidewalls. The 17-inch tires provide a softer ride with better absorption of road irregularities, suitable for comfort-focused driving. These size options offer flexibility to customize balance between ride comfort, handling, and appearance.

The Mercedes-Benz R-class Long (V251) features a ground clearance of 148 mm (about 5.8 inches). This moderate clearance strikes a balance between a sporty stance and practicality, sufficient to clear typical urban obstacles like speed bumps and curbs comfortably. However, it is lower than traditional SUVs, so while it offers better handling and a lower center of gravity, it might be less ideal for rough off-road conditions. It is well-suited for paved roads and light off-road use, appealing to buyers wanting a vehicle with a luxurious feel combined with practical height.

The Mercedes-Benz R-class Long (V251) from 2006 to 2010 was designed as a luxurious large station wagon with emphasis on versatile passenger and luggage space. It typically featured three-row seating configurations, plush interiors, advanced safety features, and high-end materials. It was aimed at families and individuals seeking a premium vehicle capable of long-distance comfort and practical cargo hauling, with enough room for 6 or 7 passengers. The extended length allowed for additional legroom, making it particularly attractive for European and American markets requiring spacious multi-person transport without resorting to bulky SUVs.
