The Mercedes-Benz Viano, specifically the W639 generation with the 2010 facelift, represents a significant offering in the mid-size multi-purpose vehicle (MPV) segment. While not officially sold in the United States, the Viano was a popular choice in Europe as a premium alternative to vans like the Volkswagen Multivan and Ford Galaxy. Positioned between a standard passenger van and a luxury SUV, the Viano aimed to provide a comfortable and versatile experience for families and businesses alike. This article focuses on the CDI 2.2 (163 Hp) 4MATIC Automatic variant, produced between September 2010 and March 2014.
Mercedes-Benz Viano W639: A Detailed Overview
The W639 Viano, launched in 2003, was a successor to the Vito and V-Class models. The 2010 facelift brought cosmetic and technological updates, enhancing its appeal. The Viano distinguished itself with a focus on passenger comfort and a more refined interior compared to purely commercial vans. The 4MATIC all-wheel-drive system, as featured in the CDI 2.2 variant, further broadened its usability, particularly in regions with inclement weather. The Viano served as a flexible platform, available in various configurations, including passenger vans, cargo versions, and even specialized models for accessibility.
Engine & Performance
The Viano CDI 2.2 4MATIC is powered by the OM 651 DE 22 LA, a 2.1-liter inline four-cylinder diesel engine. This engine produces 163 horsepower at 3800 rpm and 360 Nm (265.52 lb.-ft.) of torque between 1600 and 2400 rpm. The engine utilizes a diesel commonrail fuel injection system and is equipped with a turbocharger and intercooler to optimize performance and efficiency. Power is delivered to all four wheels via a five-speed automatic transmission (G-NAG). This combination results in a 0-100 km/h (0-62 mph) acceleration time of 13 seconds and a maximum speed of 174 km/h (108.12 mph). The weight-to-power ratio is 12.5 kg/Hp, and the weight-to-torque ratio is 5.7 kg/Nm, indicating a reasonable balance between power and weight for its class.
Design & Features
The Viano W639 is a five-door minivan with seating for up to six passengers. Its body style is characterized by a relatively long wheelbase (3200 mm / 125.98 in.) and a spacious interior. The 2010 facelift included revised front and rear styling, updated interior trim, and improved safety features. The 4MATIC system provides enhanced traction and stability, making it suitable for various road conditions. Key features of the Viano CDI 2.2 4MATIC include an anti-lock braking system (ABS), electric power steering, and comfortable seating arrangements. The vehicle’s dimensions are 4763 mm (187.52 in.) in length, 1901 mm (74.84 in.) in width, and 1875 mm (73.82 in.) in height. The Viano prioritized practicality and comfort, offering a versatile space for passengers and cargo.
