Smaller and lighter than its well-known SUV siblings, the 2013-model GLK is also equipped with a new direct-injection 3.5-liter V6 engine with 302 horsepower and 273 lb.-ft. of torque, an innovative ECO Start/Stop system, a more fuel-efficient seven-speed automatic transmission with Direct Select and electromechanical steering. A fuel-sipping four-cylinder diesel model, the GLK250 BlueTEC, will arrive early next year.
A new option for the 2013-model GLK, Blind Spot Assist uses dedicated radar sensors to monitor both blind spots behind the vehicle. Whenever a turn signal is activated with a vehicle in the blind spot, the driver gets visual and audible warnings. A separate option, Active Blind Spot Assist incorporates an intervention feature, in which ESP braking automatically helps correct the car’s course if the driver doesn’t heed the initial warning.
For the first time on the GLK, an optional DISTRONIC PLUS adaptive cruise control system uses radar sensors to help maintain a pre-set following distance behind the vehicle ahead. The system can actually brake the car to a full stop and accelerate it again. DISTRONIC PLUS works at speeds up to 125 mph and can be especially helpful in stop-and-go traffic.
Short-range 24-gigahertz radar sweeps the first 66 yards in a fan-shaped 60-degree pattern, working in tandem with a narrower 18-degree beam of 77-gigahertz radar. The two radar frequencies complement each other to cover a full range of more than 220 yards – longer than two football fields.
All cars equipped with the optional radar-based DISTRONIC PLUS system reap the benefit of another revolutionary Mercedes-Benz safety feature – PRE-SAFE® Brake. To reduce accident severity, the latest version of PRE-SAFE Brake applies full braking automatically in emergencies.
