Start your engine and feel power and control. Choose from two powerful turbocharged 4-cylinder diesel engines or opt for the range topping V6 diesel engine. The 4-cylinder engine has a capacity of 2.3 litres, and is available with a choice of two power outputs: 120kW or 140 kW. Alternatively, the 3 litre V6 generates 190kW of power and will provide exceptional performance when cruising, towing and overtaking. The range of X-Class engines mean you’ll never be short on performance.

In changing city traffic conditions or on the open road, the X-Class seven-speed automatic gearbox combines driving dynamics with driving pleasure. And the result is fast, efficient gear changes and fuel-efficiency, even when overtaking at highway speeds*.

_{*7G-TRONIC PLUS auto transmission is standard on X 350 d V6 variants. A different 7-speed automatic transmission is optionally available on the X 250 d. The X 220 d is available with a manual transmission only.}    

Whether you’re chasing off-road adventure or looking for on-road performance, the X-Class’ permanent all-wheel drive system provides stability and control under a range of conditions. With a choice between engageable all-wheel-drive on 4 cylinder variants or the permanent all-wheel-drive of the V6, you’ll have no problem dealing with demanding terrain. For added off-road confidence, all 4MATIC variants feature a locking rear differential, low range transmission and Downhill Speed Regulation that consistently adjust to the conditions.

The X-Class has the security of an extra pair of eyes for the driver, watching the road carefully. Lane Keeping Assist (4-cylinder variants) vibrates several times to alert the driver if they’re veering out of a marked lane. Active Lane Keeping Assist (V6 variants) further enhances this feature via selective braking, actively guiding the vehicle back into its lane.

_{Various safety systems and features included in Mercedes-Benz vehicles are driver assistance aids only and the driver at all times remains solely responsible for maintaining proper control of the vehicle, ensuring safety and monitoring the driving environment and complying with all applicable road rules.}

The X-Class keeps you in control. With a choice of five driving modes on V6 variants, the driving characteristics can be changed by fingertip control – from relaxed and comfortable to sporty and dynamic. These modes modify the engine response, the automatic transmission's shift points, and the ECO start/stop function.
