Mercedes-Benz Unimog U 5000 (series 437.4): four-cylinder engine rated at 160 kW, rear-wheel drive with switchable four-wheel drive, built 2002 to 2013, top speed around 90 km/h.
The Unimog U 5000 of the 437.4 series was built between 2002 and 2013 by Mercedes-Benz at its Gaggenau plant as one of the modern, deep-off-road Unimog lines. Vehicles of this series frequently served as the base for expedition and living bodies, and in disaster relief work, where extreme off-road ability is required.

The water-cooled four-cylinder engine displaces 4,801 cm³ and produces 218 hp (160 kW) at 2,200 rpm. Drive runs through the rear axle with switchable four-wheel drive, shifted through an eight-forward, six-reverse gearbox. Fitted with 14.5 R20 tyres front and rear and a 3,250 mm wheelbase, the U 5000 reaches a top speed of around 90 km/h.
At around 90 km/h the U 5000 is well above the 60 km/h limit of the T tractor licence class and is registered as a lorry. Portal axles combined with a pendulum rear axle give the vehicle the wheel articulation and ground clearance typical of the Unimog in demanding terrain. The 14.5 R20 tyre size is matched to exactly this kind of use.
When buying a used U 5000, the history of the body matters, since many vehicles served as a base for living or expedition bodies whose mounting to the chassis needs checking. The portal axles need their own oil in the hub reduction gears and should be checked for leaks. The rear pendulum axle and its bearings should be checked for play. Spare parts are available through Mercedes-Benz's Unimog programme.
