The high-torque common-rail diesel drive system with a displacement of 2.3 litres is available with a choice of two power outputs.
In the X 220 d with single turbocharger it generates 120 kW/163 hp and in the biturbo X 250 d no less than 140 kW/190 hp.
The X 200's petrol engine outputs 122 kW/165 hp. All engines are characterised by quiet, low-vibration running and excellent power delivery coupled with low consumption figures.
In mid-2018 the top-of-the-range high-torque V6 diesel engine will be released, ensuring even greater agility on- and off-road.
Six-speed manual or seven-speed automatic transmission
Both diesel variants are available as left- or right-hand drive vehicles with purely rear wheel drive or with engageable all-wheel drive.
Due to very specific market requirements, for example in Dubai and Morocco, the X 200 petrol model is only available as a left-hand drive vehicle with rear wheel drive.
Power is transferred via a six-speed manual transmission. Its special feature is the wide transmission spacing, with a short first gear for maximum torque and a long sixth gear to keep rev speeds down.
This design makes allowance for typical situations such as hill starts with a horse or boat trailer in tow and long-distance comfort on motorways.
Furthermore, the manual transmission combined with a diesel engine can be equipped with the ECO start/stop function as an option in various markets.
This makes an important contribution to the X-Class's moderate fuel consumption. As soon as the driver brakes, disengages the gear and releases the clutch, the engine switches off automatically when the vehicle is at a standstill.
When the clutch is engaged, the engine immediately starts again. This saves on fuel, particularly in urban traffic.
A seven-speed automatic transmission is available on request for the 140 kW/190 hp X 250 d and X 250 d 4MATIC models.
