The Mercedes-Benz GLK was introduced as a subcompact luxury SUV for the 2010 model year. This first-generation GLK features a 3.5-liter V6 engine with 268 horsepower, mated to a seven-speed automatic transmission, and it's available with either rear-wheel or all-wheel drive. Inside, the GLK offers a finely crafted cabin with top-notch materials and a wide array of high-tech features. Notable safety equipment includes nine airbags and Mercedes' PRE-SAFE system, which tightens the seat belts and closes the windows when a collision is imminent. The COMAND infotainment system, complete with a 7-inch display, and other amenities like Bluetooth and an 8-speaker audio system are standard.
