Power boost for Mercedes-Benz Unimog

Mercedes-Benz Unimog

Mercedes-Benz Trucks has introduced two new powertrains for the Unimog implement carrier, boosting power by 54PS.

The new U435 and U535 derivatives produce 354PS and 1,380Nm. They use a 7.7-litre six-cylinder diesel engine.

A new automated manual transmission has been developed to manage the higher outputs of the U435/U535. The Opti-drive system’s improved gear change co-ordination and clutch control produces quicker shifts that translate into a smoother ride and improved fuel-efficiency.

Mercedes-Benz Trucks says the new transmission is expected to prove popular with UK operators as an alternative to the standard-fit manual gearbox.

The Unimog implement carrier can also now be specified, for the first time, with self-levelling suspension for the rear axle. This new set-up, which employs gas storage tanks and hydraulic cylinders, instead of the usual coil springs, promises benefits in terms of comfort and operational efficiency.

As well as providing a constant driving level irrespective of load status or any rear attachments that may be fitted, the hydropneumatic system contributes to handling stability and assists operators when coupling and uncoupling implements.

A new Comfort steering option, meanwhile, makes it easier for drivers to turn the wheel at low, manoeuvring speeds, or when stationary, and is particularly helpful when the vehicle is fitted with large-volume tyres or heavy front implements such as mowers. The electrohydraulic steering adapts to the driving situation.

The U435 and U535 have maximum gross weights (with relevant special equipment) of 14 tonnes and 16.5 tonnes respectively. The first examples are expected to reach the UK next month (January).

Ross Paterson, head of special trucks at Mercedes-Benz, said: “Mercedes-Benz Trucks is committed to the continuous improvement of its range. This, of course, applies every bit as much to the Unimog – a vehicle first seen in 1946 and that now enjoys legendary status – as it does to other, more mainstream products.

“Many of the innovations and developments we’ve introduced have been in direct response to feedback from those, here in the UK, who buy and operate our vehicles. We listen to what they tell us, and wherever possible we deliver what they need.

“That’s certainly been the case where the U435 and U535 are concerned. Farmers and arboriculturalists in particular, wanted that little bit more power and torque at the wheels for in-field operations, as well as for trailer work.”

The Mercedes-Benz Unimog team will be exhibiting at the LAMMA 2022 agricultural machinery, equipment and technology show, which takes place on January 11-12. On its stand at the NEC, Birmingham, will be a U530 and a U430, as well as a UHE extreme off-roader with crane.
