The W639 Viano underwent a facelift in 2010, bringing updated styling, improved interior features, and enhancements to the engine range. This iteration of the Viano aimed to solidify its position as a luxurious and practical MPV, appealing to customers seeking a vehicle capable of handling diverse needs, from transporting passengers to carrying cargo. The CDI 2.2 model, with its automatic transmission, was a common configuration, providing ease of use and convenience for everyday driving.
Engine & Performance
The heart of the Viano CDI 2.2 is a 2.2-liter inline-four cylinder diesel engine, designated OM 651 DE 22 LA. 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 turbocharger with an intercooler and a diesel commonrail fuel injection system to optimize performance and efficiency. Power is delivered to the rear wheels via a five-speed automatic transmission – G NAG. This configuration allows for a 0-100 km/h (0-62 mph) acceleration time of 11.1 seconds, and a 0-60 mph time of approximately 10.5 seconds. The Viano CDI 2.2 achieves a maximum speed of 182 km/h (113.09 mph). The weight-to-power ratio is 12 kg/Hp, and the weight-to-torque ratio is 5.4 kg/Nm, indicating a reasonable balance between power and weight.
