Major changes included:
Mercedes-Benz leaped into the luxury compact SUV segment with the 2010 release of the GLK350, which featured a relatively boxy body and the signature grille. Under the GLK350's hood was a 3.5-liter V6 engine that produced 268 horsepower and 258 pound-feet of torque through a seven-speed automatic transmission. The GLK350 came standard with rear-wheel drive, but 4MATIC all-wheel drive was an option. In 2013, Mercedes pushed the V6 engine in the GLK350 to 302 horsepower and 273 pound-feet of torque.
