Mercedes-Benz Trucks has responded to customer feedback by introducing more powerful versions of its 4×4 Unimog UGE implement carrier.
Now available for order by UK operators, the U435 and U535 produce 260 kW (354 hp). This represents an increase of 40 kW (54 hp) on the highest output previously available from the Euro VI Step E 7.7 litre in-line six cylinder engine. Maximum torque is up by 180 Nm to 1,380 Nm, which is available from 1,800 rpm.
Daimler Truck engineers have also purpose designed and built an automated manual transmission 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. As a result, it is expected to prove popular with UK operators as an alternative to the standard-fit manual gearbox.
In other developments, the Unimog implement carrier can 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, offers 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 delivers a ‘feel’ that 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 in January 2022.
The latest round of product enhancements cap a memorable 75th anniversary year for the Mercedes-Benz Unimog. Although it offers many of the attributes of both, this unique vehicle is neither a truck, nor a tractor. It enjoys an unrivalled reputation as the ultimate off-roader, but also achieves impressive on-road speeds of up to 56 mph (where applicable).
Unimogs are chosen for the most arduous applications by a broad spectrum of operators, particularly those engaged in the agriculture and arboriculture, utilities, municipal and emergency services sectors. They are also engaged in highly specialised roles such as railway infrastructure maintenance– the vehicle can even be adapted to run on rails.
