2013 Mercedes Benz GLK350
Mercedes boosted the power and fuel economy of the 3.5-liter V-6 to 302 horsepower and 273 lb-ft of torque, increases of 34 hp and 15 lb-ft over the outgoing model. The seven-speed automatic transmission gains an ECO stop-start system, lower-slip torque converter, and new fluid to improve efficiency. Mercedes’ 4Matic all-wheel-drive system is split 45:55 front to rear. Electromechanical steering assist with speed-sensitive assist and a variable ratio replaces the previous model’s hydraulic setup. Fuel economy for all-wheel-drive models is now rated 19/24 mpg city highway, improvements of 3 mpg for both figures.
On the road, the 302-hp V-6 and seven-speed automatic combo moves the 2013 GLK350 with authority. Stomping on the throttle from a stop launches the 4183-pound SUV hard and without tire chirp, thanks to its four-wheel grip. The seven-speed offers a sport mode that holds gears longer and quickens response time when accelerating. Steering column-mounted paddle shifters allow for more control over shift points.
