Last updated August 4, 2026

The 2012 Mercedes-Benz GLK-Class is a carryover with no major changes. It keeps the same two-trim lineup, V6 powertrain, styling, safety equipment, and cabin technology as the 2011 model.
About the 2012 Mercedes-Benz GLK-Class
1st generation (2010-2015 U.S. market), pre-refresh year; third U.S. model year before the 2013 facelift.
Mercedes-Benz positions the GLK as a compact luxury SUV with the road manners of one of its sport sedans. The pitch centers on upright SUV usefulness, a strong V6, and a solid, tailored cabin rather than maximum cargo room or soft-riding isolation. Against rivals, the GLK leans into boxy styling, a planted feel, and traditional Mercedes hardware, especially for shoppers who want a smaller SUV that still feels substantial and premium.
The 2012 GLK-Class is a compact luxury SUV with a solid cabin and road-focused handling. The rear-wheel-drive GLK 350 emphasizes sedan-like road manners, while the GLK 350 4MATIC adds all-wheel drive for better traction in poor weather. Both use a 268-hp 3.5-liter V6 and seven-speed automatic, with Bluetooth, power front seats, and dual-zone climate control.
