It looks like Mercedes-Benz kept their promise of introducing a beefier powetrain for the Nissan Navara-based X-Class pickup. Revealed ahead of its debut at this year's Geneva International Motor Show is the X350d 4MATIC which gets a high-output turbo-diesel V6 engine.

The six-cylinder turbo motor displaces 3.0-liters and benefits from common rail direct injection (CRDi) and variable turbine geometry (VTG). It puts out a healthy 258 PS along with a massive 550 Nm of torque available between 1400 – 3200 rpm. 0 – 100 km/h is achieved in 7.9 seconds while top speed is rated 205 km/h. The V6 also benefits from Nanoslide cylinder coating technology which makes for a smoother running engine, as well as better fuel economy.

Power is then sent to a 4MATIC all-wheel drive system and seven-speed 7G-Tronic Plus automatic transmission. According to Mercedes-Benz, the drivetrain has a fixed torque split of 40:60 which allows the X350d to have better acceleration as claimed by the automaker. In addition, the X350d has three different settings; 4MAT for a sportier drive on-road, 4H for improved traction off-road and 4L which acts as the low-range mode with a reduction gearing of 1:2.9. 4L also allows drivers to lock the rear differential.

Beyond the new V6 and upgraded 4MATIC all-wheel drive system, the X350d also has Dynamic Select driving modes which can modify the engine's characteristics, transmission shift points and Eco Start/Stop function. The modes include Comfort, Eco, Sport, Manual and Off-road.

As for the X350d's design, it pretty much remains the same as with the four-cylinder X200 and X220d and X250d models. However, Mercedes-Benz introduced new wheel designs that are available in 17-, 18- and 19-inches. Also available are the new sports / style bar, bed covers, bed linings, anchor rails and even underbody protection.

Two models will initially be available for the X350d, Progressive and Power. The former comes with 17-inch alloys, electroplated silver chrome air vents, leather steering wheel, black fabric seats and an 8-speaker infotainment system.

The 2018 Mercedes-Benz X-Class X350d will be shown in the metal at this year's Geneva International Motor Show.
