The 3.0-litre six-cylinder diesel engine of Mercedes-Benz X 350 d 4MATIC with common-rail direct injection impresses with its sheer assertiveness. Its maximum torque of 550 Nm is available over a wide engine speed range from 1400 to 3200 rpm. This means that high torque is already available from low engine speeds. Whether for a sporty driving style, comfortable long-distance touring, or off-road driving in difficult conditions – the V6 always ensures serene and efficient progress. Its special features include lightweight design, the single-stage turbocharger with variable turbine geometry for particularly agile engine response, and the innovative NANOSLIDE® cylinder liner coating also used in Formula 1.

The 7G-TRONIC PLUS automatic transmission included as standard, complete with steering wheel shift paddles, operates with no interruption in tractive power during gearchanges. This improves the handling on gradients, in off-road terrain, and when towing a trailer. Further advantages include fast shift operation and a low engine speed level. This has a positive effect especially with regard to efficiency and noise levels. The wide gear spacing allows an individual driving experience via the DYNAMIC SELECT system. Manual gear changes are also possible using the shift paddles on the steering wheel.
