The Mercedes-Benz Viano (W639), particularly the facelifted model produced from 2010 to 2014, 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 sophisticated features. The CDI 3.0 variant, equipped with a 224 horsepower diesel engine and automatic transmission, was a flagship model within the Viano range.
Mercedes-Benz Viano (W639) CDI 3.0: An Overview
The W639 generation Viano underwent a substantial facelift in 2010, bringing revised styling, improved interior appointments, and updated engine options. The CDI 3.0 model, powered by the OM642 DE 30 LA engine, focused on delivering a balance of performance and fuel efficiency. Its rear-wheel-drive configuration and available seating for up to six passengers made it suitable for both family transport and executive shuttle services. The Viano’s design emphasized a more car-like experience compared to traditional commercial vans, appealing to a broader customer base.
Engine & Performance
The heart of the Viano CDI 3.0 is its 3.0-liter turbocharged diesel engine, designated OM 642 DE 30 LA. This V6 powerplant produces 224 horsepower at 3800 rpm and a substantial 440 Nm (324.53 lb.-ft.) of torque available from a low 1400 to 2800 rpm. This broad torque curve provides strong acceleration and effortless cruising, even when fully loaded. The engine utilizes a common rail direct injection system and an intercooled turbocharger to optimize combustion and power delivery. Paired with a 5-speed automatic transmission (NAG), the Viano CDI 3.0 achieves a 0-100 km/h (0-62 mph) time of 9.1 seconds and a top speed of 201 km/h (124.9 mph). Calculated 0-60 mph acceleration is 8.6 seconds. Fuel consumption is rated at 8.5-8.6 liters per 100 kilometers (27.7-27.4 US mpg) combined, with CO2 emissions ranging from 224-226 g/km.
Design & Features
The Mercedes-Benz Viano boasts a minivan body style with five doors and seating for six occupants. Its exterior design, particularly after the 2010 facelift, features a more refined and contemporary aesthetic than many of its competitors. The interior is characterized by a spacious cabin, comfortable seating, and a focus on practicality. Key features include a well-appointed dashboard, ergonomic controls, and ample storage compartments. Safety features, typical of Mercedes-Benz, include ABS (Anti-lock Braking System) and a robust chassis designed for stability. The Viano’s dimensions – a length of 4763 mm (187.52 in.), a width of 1901 mm (74.84 in.), and a height of 1875 mm (73.82 in.) – provide a generous interior volume. A wheelbase of 3200 mm (125.98 in.) contributes to a comfortable ride. The kerb weight ranges from 2055 to 2080 kg (4530.5 – 4585.62 lbs.), with a maximum permissible weight of 2800 kg (6172.94 lbs.) and a maximum load capacity of 720-745 kg (1587.33 – 1642.44 lbs.).
