2012 Mercedes-Benz B-class (W246) Dimensions, Size & Specs

The curb weight of the W246 B-class ranges from 1350 kg to 1530 kg (approximately 2976 to 3372 lbs), depending on the specific configuration and equipment levels. The maximum permissible weight varies between 1900 kg and 2055 kg (about 4189 to 4532 lbs). This weight range indicates a robust build, balancing performance and safety with practical utility.

With rear seats upright, the Mercedes-Benz B-class W246 provides a generous 488 liters (17.2 cubic feet) of luggage capacity, which is considerable for its class. When the rear seats are folded down, the luggage space expands significantly to 1547 liters (54.6 cubic feet), making it highly versatile for carrying larger or bulkier items. This flexibility enhances the vehicle's practicality for families and those needing extra cargo room.

The B-class W246 offers multiple tire and rim size configurations. The popular rim sizes include 15-inch, 16-inch, and 17-inch options, specifically rims sized 6.5J x 16 or 17. Corresponding tire sizes are 195/65 R15, 205/55 R16, and 225/45 R17. These options allow owners to balance between comfort, handling, and aesthetic preferences depending on their driving needs.

The maximum roof load capacity of the 2012 Mercedes-Benz B-class (W246) is 75 kilograms (approximately 165 pounds). This means that when carrying roof racks, carriers, or any additional rooftop equipment, you should not exceed this weight limit to maintain vehicle stability and safety.

Given the B-class W246's length of 4359 mm (171.5 inches) and width of 1786 mm (70.3 inches), it fits well within the dimensions of a standard garage, which is typically around 6000 mm (236 inches) in length and 3000 mm (118 inches) in width. The width with mirrors folded is also comfortably less than most garage door openings, though drivers should be cautious of the mirror-opened width of 2010 mm (79.1 inches) when maneuvering. Overall, this car is well-suited for home garages in most urban and suburban settings.

Compared to its predecessor, the W245 generation, the W246 B-class has grown slightly in overall size. The 2012 model is longer and wider, offering more interior space and increased luggage capacity. This increase was aimed at improving passenger comfort and cargo versatility without significantly compromising maneuverability. The W246's modern design also helped enhance aerodynamics and aesthetic appeal compared to the boxier shape of the previous model.

When compared to similar premium compact hatchbacks, such as the Audi A3 Sportback and BMW 1 Series, the Mercedes-Benz B-class W246 tends to offer more interior space and cargo capacity due to its taller roofline and hatchback design. While slightly wider and taller, it may be less sporty but provides enhanced practicality and comfort. Its dimensions strike a balance between maneuverability and spaciousness, making it a strong contender in the compact luxury hatchback market.

The 2012 Mercedes-Benz B-class (W246) offers a combination of compact exterior dimensions, versatile interior space, and ample luggage capacity, making it ideal for daily commuting, family use, and weekend trips. Its manageable size facilitates urban parking and maneuvering, while the spacious cabin and flexible cargo area ensure comfort and utility. Added features like multiple tire and rim options allow customization for driving preferences, and a solid weight distribution enhances safety and driving dynamics.

The W246 B-class uses tire sizes 195/65 R15, 205/55 R16, and 225/45 R17, depending on rim selection and trim. Smaller tires, like the 195/65 R15, provide a smoother and more comfortable ride, ideal for city driving and efficiency. Larger tires such as 225/45 R17 enhance handling and cornering stability but may slightly reduce ride comfort and increase road noise. The choice affects fuel economy, grip, and overall driving experience, allowing buyers to tailor the car to their needs.
