2012 Mercedes-Benz R-Class: What's New, Specs & Features
Last updated August 4, 2026

About the 2012 Mercedes-Benz R-Class
First-generation R-Class (W251), refreshed for 2011; 2012 is the second year after that update and the final U.S. model year.
Mercedes-Benz pitched the R-Class as a three-row luxury family vehicle that blended sedan comfort, wagon cargo room, and SUV-style all-weather traction. The brochure emphasizes first-class travel for six or seven people, standard 4MATIC grip, advanced safety, and quiet long-distance comfort rather than off-road image. In practice, it was aimed at buyers who wanted more passenger space than a typical luxury crossover but did not want a traditional minivan experience.
Mercedes positions the gas R 350 as the familiar family-focused version, with six seats, standard all-wheel drive, sliding second-row captain’s chairs, and a fold-flat third row. The BlueTEC pairs the same three-row cabin with a turbo-diesel V6 producing 400 lb-ft of torque for stronger low-speed pull and relaxed highway travel.
