2010 Mercedes-Benz R-Class: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2010 Mercedes-Benz R-Class is standard POST-SAFE, which responds after a collision by unlocking the doors, switching on the lights, and shutting off the engine. This is a light update rather than a redesign, with revised trim names and a few styling and equipment changes.
About the 2010 Mercedes-Benz R-Class
First generation (W251), final US model year before the 2011 front-end restyle and interior refresh.
Mercedes-Benz pitched the R-Class as something between a luxury wagon and a family crossover: lower and smoother on the road than a traditional SUV, but roomier than a typical wagon. Its core appeal was three-row seating, standard AWD, long-distance comfort, and Mercedes safety in a shape that felt more car-like than truck-like. For most shoppers, the R-Class was the choice for carrying adults in comfort without moving to a minivan or a taller full-size SUV.
Mercedes positioned the gas-powered R 350 4MATIC Sport as the all-around choice, with three-row seating, standard AWD, a 268-hp V6, and self-leveling rear air suspension. The R 350 BlueTEC Sport emphasized long-distance travel and stronger low-speed pull from its turbo-diesel V6, which produces 400 lb-ft of torque; both versions have a sunroof, a 6.5-inch infotainment screen, Bluetooth hands-free calling, and power front seats.
