The Mercedes-Benz Viano (W639) is a luxury minivan produced by Mercedes-Benz from 2003 to 2014. The W639 generation, specifically the 2.0 CDI variant with 115 horsepower and an automatic transmission, was available from 2007 to 2010. This model occupied a niche market, primarily in Europe, offering a more premium and versatile alternative to standard passenger vans. While not officially sold in the United States, the Viano represents Mercedes-Benz’s approach to a multi-purpose vehicle, blending passenger comfort with commercial practicality. It served as a competitor to vehicles like the Volkswagen Multivan and the Chrysler Voyager in the European market.
Mercedes-Benz Viano (W639) 2.0 CDI: An Overview
The Viano W639 was designed to bridge the gap between a traditional passenger van and a luxury MPV (Multi-Purpose Vehicle). It offered a range of seating configurations, from five to seven passengers, and emphasized comfort and features. The 2.0 CDI engine variant, equipped with a diesel particulate filter (DPF), aimed to balance performance with environmental considerations, meeting the increasingly stringent Euro 4 emission standards of the time. The automatic transmission provided ease of driving, particularly in urban environments. The Viano was often chosen by families, businesses requiring executive transport, and individuals seeking a spacious and well-appointed vehicle for leisure activities.
Engine & Performance
The heart of the Viano 2.0 CDI is a 2.1-liter (2148 cm3) inline-four cylinder diesel engine, designated OM 646 DE 22 LA. This engine produces 115 horsepower (Hp) at 3800 rpm and 290 Newton-meters (213.89 lb.-ft.) of torque at 1600 rpm. The power-to-liter ratio is 53.5 Hp/l. The engine utilizes a turbocharger with an intercooler to enhance performance and efficiency. Power is delivered to the rear wheels via a five-speed automatic transmission. While not designed for outright speed, the Viano 2.0 CDI offers adequate performance for everyday driving and long-distance travel. Acceleration from 0 to 100 km/h (0-62 mph) takes 17.3 seconds, and 0 to 60 mph is achieved in approximately 16.4 seconds. The vehicle has a maximum speed of 153 km/h (95.07 mph).
