This delivers powerful torque at low revs and more output at the top end of the rpm range. Immediate response times, good pulling power and strong acceleration are thus guaranteed.
The large turbocharger is designed for high throughput and kicks in when the revs are going up. This evens out the acceleration right through to the upper limit of the rpm range, creating the ideal prerequisites for a dynamic driving experience as well as for transporting heavy loads and for trailer operation.
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.
