World premiere: Mercedes-Benz presents the X-Class
six-cylinder engine and permanent all-wheel drive
by Jim Davis | 01 March 2018
At the Geneva Motor Show in early March, the Mercedes-Benz X-Class with a powerful six-cylinder engine and 4MATIC permanent all-wheel drive will celebrate its world premiere. The X 350 d 4MATIC (provisional figures: fuel consumption combined: 9.0 l/100 km, combined CO2emissions: 237 g/km) delivers 190 kW (258 hp) and a maximum torque of 550 newton metres. The top model sprints from zero to 100 km/h in 7.9 seconds. The permanent all-wheel drive of the X 350 d 4MATIC ensures a high level of driving stability and dynamism under a wide range of conditions – including wet and wintry roads. As standard the X 350 d 4MATIC is equipped with the 7-speed automatic transmission 7G-TRONIC PLUS with steering wheel shift paddles and the ECO start/stop function. The DYNAMIC SELECT transmission mode switch for individual driving pleasure is also included as standard. This top-of-the-line model will be available in Europe from mid-2018, in the equipment lines PROGRESSIVE and POWER. In Germany it is available at a price from Euro 53,360 (incl. 19 percent VAT). To suit the X-Class to customer wishes even more individually, Mercedes-Benz has expanded the extensive range of accessories. New items include three rim designs, the Sports Bar, the Rollcover in black and the Softcover.
The performance of the X-Class is not only thrilling off-road, but also on the road. The wide track, the long wheelbase and the sophisticated design of the comfort suspension with a double wishbone front axle, the multi-link rear axle with a rigid section and coil springs at both axles ensure plenty of on-road driving pleasure and driving dynamics – with no compromises when off-road.
Superior performance and fast gearshifts
The 190 kW (258 hp) 3.0-litre six-cylinder diesel engine with common-rail direct injection impresses with its muscular power delivery. The maximum torque of 550 newton metres is available over a wide engine speed range of 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 guarantees 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 operates with no interruption in tractive power during gearchanges. This leads to better handling characteristics on uphill gradients, when driving off-road and when towing a trailer. Other advantages of 7G-TRONIC PLUS are fast gearshifts and low rpm. This has a positive effect especially with regard to efficiency and noise levels. Steering wheel shift paddles also allow the driver to engage gears manually.
DYNAMIC SELECT for an individual choice of driving characteristics
The X 350 d 4MATIC features a driving mode switch as standard that is rarely encountered in the pickup segment. The DYNAMIC SELECT system has five driving modes for very individual driving pleasure – from relaxed and comfortable to sporty and dynamic. These modify the engine characteristics, the automatic transmission’s shift points and the ECO start/stop function:
- Comfort (C): This mode is activated automatically when the engine starts. It provides comfort-emphasising, harmonious accelerator characteristics as well as early shift points.
- ECO (E): 7G-TRONIC PLUS changes the gears at particularly low engine speeds.
- Sport (S): The engine responds more immediately to throttle input. The automatic transmission makes use of the entire engine speed range to change gears, and shifts at higher engine speeds.
- Manual (M): The automatic transmission can be manually operated using the gearshift paddles on the steering wheel. This appreciably shortens the shift times compared with the Comfort and ECO modes.
- Offroad (O): This mode is suitable for driving on challenging terrain. It offers higher switch points and a flatter, and therefore more precisely adjustable, accelerator characteristic curve.
The ECO start/stop function is active in all driving modes except Offroad (O) mode.
The DYNAMIC SELECT switch is located in the central control panel on the centre console. The selected program is shown as a status and, when the program is changed, appears for a short time as a pop-up display on the instrument cluster’s multifunction display.
4MATIC permanent all-wheel drive for a wide variety of surfaces
The 4MATIC permanent all-wheel drive with low-range reduction gear and an optional rear axle locking differential ensures excellent performance and traction on a wide range of driving surfaces. The all-wheel drive system features a two-stage transfer case which is flange-mounted to the 7G-TRONIC PLUS main transmission. It is fitted with a central differential of planetary design which distributes the drive force between the front and rear axle with a fixed torque distribution of 40:60 percent. This rear-based configuration ensures improved vehicle dynamics and higher lateral acceleration on the road, and better traction during acceleration. Optimum traction on any off-road terrain is guaranteed by a continuously adjustable longitudinal differential in the transfer case, in the form of an electromechanical multiplate clutch. This ensures that the traction potential of all four wheels is fully realised on demanding terrain.
There are three different all-wheel drive modes: 4MAT for increased vehicle dynamics and 4H for improved traction off-road. 4L mode (low range) is also selectable, with a reduction gearing of 1:2.9. In addition, a 100 percent differential lock is available for the rear axle if desired. The combination of a controlled longitudinal differential lock (0–100%), rear-axle locking differential and reduction gear delivers good performance both on and off-road.
The all-wheel drive system and the suspension with its long spring travel and ground clearance of up to 222 millimetres together ensure outstanding off-road capabilities. The X-Class effortlessly climbs gradients of up to 45 degrees, fords water courses with a depth of up to 60 centimetres and maintains its poise on inclines of almost 50 degrees.
