Mercedes-Benz V-Class V300d (V447) Overview
The V-Class, introduced in 2014, aimed to elevate the standard for large passenger vans. The Extra Long variant, denoted by the V447 chassis code, extends the wheelbase and overall length, maximizing interior space. The V 300d trim level, equipped with the OM 654 diesel engine, represents a balance of performance and fuel economy within the V-Class lineup. The 4MATIC all-wheel-drive system provides enhanced traction and stability, while the 9G-TRONIC automatic transmission delivers smooth and efficient gear changes. This model is designed to accommodate between six and eight passengers comfortably, making it ideal for larger families or group travel.
Engine & Performance
The heart of the V 300d is the OM 654 2.0-liter inline-four cylinder diesel engine. This powerplant produces 237 horsepower at 4200 rpm and a substantial 390.91 lb.-ft. of torque between 1600 and 2400 rpm. The engine features bi-turbocharging and an intercooler, contributing to its responsive performance and efficiency. The 9G-TRONIC nine-speed automatic transmission is standard, providing seamless gear shifts and optimizing fuel consumption. The 4MATIC all-wheel-drive system distributes power to all four wheels, enhancing traction in various driving conditions. Acceleration from 0 to 62 mph (0-100 km/h) takes 8.6 seconds, while the vehicle achieves a maximum speed of 132.97 mph (214 km/h). The engine meets Euro 6d emission standards, incorporating a particulate filter and Start & Stop system to minimize environmental impact.
