Mercedes-Benz has confirmed full details for the newly-engined flagship version of its X-Class pick-up, which will go on sale in November priced at £38,350 excluding VAT.

The manufacturer’s new 3.0-litre V6 diesel unit, branded as 350d, produces 258hp and 550Nm of torque.

Like all X-Classes, those fitted with the new engine will have double-cab bodies but the new addition comes with 4Matic permanent four-wheel drive. The models Mercedes launched in January 2018, which are powered by the 2.3-litre diesel engine inherited from the X-Class’s donor vehicle, the Nissan Navara, come with 4Matic selectable all-wheel drive.

The new engine, paired with a seven-speed automatic gearbox, will only be available with range-topping Power trim, with entry-level Pure and mid-range Progressive specifications only available with the existing 220d and 250d derivatives of the 2.3 engine.

Exterior design features with Power trim include painted bumpers with simulated underguard in chrome, a chrome rear bumper with integrated step, chrome foglight surrounds, chrome shoulder line trim strips, LED headlights with cleaning system, LED tail lights, electric door mirrors, 18in grey alloy wheels and heated washer fluid jets.

Inside there are eight-way adjustable driver and front passenger seats, which are also heated, along with a leather steering wheel with gearshift paddles, cruise control, keyless go, leather and microfibre upholstery and a leather dashboard.

An Audio 20 CD infotainment system is standard, with a 7in screen, rotary controller with touchpad, Bluetooth, DAB digital radio and pre-installation for Garmin Map Pilot.

Safety systems include active lane keep assist, autonomous emergency braking, traffic sign assist, hill start assist and downhill speed regulation.

There’s also a Thatcham anti-theft security package and a load securing rail system.

Drivers can chose between five different drive modes – eco, comfort, sport, manual and off-road – and three four-wheel drive settings – 4MAT mode, which automatically manages torque distribution, 4H, which presents a low locking effect of the interaxle differential, and 4L, a low-range setting for difficult off-road terrain.
