The Mercedes-Benz Viano (W639), particularly the facelifted version introduced in 2010, represents a significant offering in the premium multi-purpose vehicle (MPV) segment. While not officially sold in the United States, the Viano was a popular choice in Europe as a more luxurious and versatile alternative to standard vans. Positioned above the Vito, the Viano catered to buyers seeking a blend of passenger comfort, cargo capacity, and refined driving experience. The 3.5-liter variant, producing 258 horsepower, was a top-of-the-line offering, emphasizing performance alongside practicality. Production of this generation spanned from 2010 to 2014, with the W639 platform eventually superseded by the Mercedes-Benz V-Class.
Mercedes-Benz Viano (W639, facelift 2010) 3.5
The facelifted W639 Viano, launched in September 2010 and continuing through March 2014, brought styling updates and refined features to the already capable MPV. The 3.5-liter engine option distinguished itself as the performance leader within the Viano range, offering a compelling combination of power and space. This model was primarily marketed towards families, businesses requiring executive transport, and individuals desiring a vehicle capable of both comfortable long-distance travel and practical cargo hauling.
Engine & Performance
The heart of the Viano 3.5 is the M 272 E 35 engine, a 3.5-liter naturally aspirated V6 gasoline engine. This powerplant delivers 258 horsepower at 5900 rpm and 340 Nm (250.77 lb.-ft.) of torque between 2500 and 5000 rpm. The engine features multi-port manifold fuel injection and a longitudinal front engine layout. Power is delivered to the rear wheels via a 5-speed automatic transmission (NAG). This configuration allows for a 0-100 km/h (0-62 mph) acceleration time of 10.4 seconds, and a 0-60 mph time of approximately 9.9 seconds. The Viano 3.5 boasts a maximum speed of 217 km/h (134.84 mph). The engine’s specific output is 73.8 horsepower per liter, demonstrating a relatively efficient power delivery for its displacement. The weight-to-power ratio stands at 7.7 kg/Hp, and the weight-to-torque ratio is 5.8 kg/Nm, indicating a respectable power-to-weight balance.
Design & Features
The Mercedes-Benz Viano W639 is a five-door minivan designed to accommodate up to six passengers. Its body style prioritizes both passenger comfort and cargo versatility. The 2010 facelift brought subtle but noticeable changes to the exterior, including revised front and rear fascias, updated headlights, and a more prominent grille. Inside, the Viano offered a spacious cabin with configurable seating arrangements. Features focused on comfort and convenience, including climate control, premium upholstery options, and an advanced audio system. Safety features, typical for the era, included ABS (Anti-lock Braking System) and electric power steering. The Viano’s dimensions are substantial, measuring 4763 mm (187.52 in.) in length, 1901 mm (74.84 in.) in width, and 1875 mm (73.82 in.) in height, with a wheelbase of 3200 mm (125.98 in.).
