Mercedes Unveils Luxury‑Styled Unimog to Mark 80 Years, Featuring a New 7.7‑L Six‑Cylinder Engine

Breaking: Mercedes unveils luxury Unimog concept as eight-decade model milestone approach

mercedes-Benz is signaling a bold shift for its rugged Unimog lineage by introducing a luxury-oriented show car. Created in collaboration with Hellgeth Engineering, the special edition fuses the Unimog’s legendary all-weather capability with premium materials and upscale styling for both muddy trails and upscale settings.

Technical core and power

At its heart remains the Model U 4023 unimog platform, featuring portal axles, a flexible frame, and three locking differentials. The standout upgrade is a 7.7-liter inline-six OM 936 diesel engine producing about 300 horsepower, replacing the usual 5.1-liter inline-four. Mercedes says the six-cylinder setup enhances traction and smoothness of shifting while preserving the truck’s renowned off-road performance.

Exterior design and tech upgrades

The exterior blends rugged strength with refined styling. Design tweaks draw on SUV cues, including a revised grille, new bumper and side skirts, plus tailored cargo-area panels. The finish leans matte gray with 20-inch wheels and a distinct LED headlight package. MirrorCam technology replaces conventional mirrors with digital displays, a feature Mercedes highlights for both off-road use and tight urban driving.

Interior impression and purpose

Inside, the cabin seats four in premium leather with contrast stitching and ambient LED lighting. The ambience aims to merge luxury ambiance with practical utility, though official interior photos are limited, giving the impression of a rugged truck rather than a limousine.

Heritage, testing, and potential future

The Unimog lineage dates back to postwar Germany, with production eventually taken over by Mercedes in 1951. Over decades, the model has served utility providers, rescue services, the military, and even Dakar Rally teams, prioritizing capability over luxury. Mercedes emphasizes this concept is more than a styling exercise: a customer will test the show car next year to gather real-world data for potential future advancement.Strong demand could pave the way for a new sub-branch within the unimog family.
