A new 329-hp 3.0-liter V-6 combines twin turbos, stratified-charge combustion and numerous other advances to lower emissions and fuel consumption while increasing performance.
In a single millisecond, the rapid-multispark ignition can fire up to four times, while the high-pressure Direct Injection precisely tunes the ultrafine fuel spray. A lightweight diecast-alloy block, widely variable valve timing, reduced friction, and clever "on-demand'' ancillary components further boost efficiency.
ECO Start/Stop system
A fuel-saving ECO Start/Stop system automatically shuts off the engine at stoplights and other idle situations. As soon as the driver lifts off the brake, the engine instantly restarts, for immediate acceleration response. The ECO Start/Stop system can also be shut off by the driver at any time.
4MATIC all-wheel drive
In any season, on any road, 4MATIC all-wheel drive adds to your confidence and control. Always engaged and optimizing torque to every wheel, 4MATIC integrates with ESP, our standard Electronic Stability Program, for maximum effectiveness in corners and slippery conditions. It also incorporates our 4-wheel Electronic Traction System (4-ETS), which monitors for the first sign of wheel slip and responds to ensure torque is sent to the wheels with the best grip, even if that's only one wheel.
7-speed automatic transmission with shift paddles
Smooth, responsive and efficient, the 7-speed automatic offers the ideal response in virtually every driving situation, from relaxed cruising to quick acceleration. Two overdrive ratios enhances highway fuel-efficiency. An electronic selector and shift paddles on the steering wheel let you control all gear changes with your hands on the wheel. Adaptive logic paces automatic shifting to match your driving style. And the shift paddles let you enjoy manual control anytime.
