Heavy-duty trucking: The Actros SLT and Arocs SLT


Mercedes-Benz SLT: a purpose-built heavy-haulage truck with a massive amount of torque. The new SLT is a high-calibre specialist developed by Mercedes-Benz to meet the requirements of a highly demanding transport segment.

The basic SLT truck is manufactured at the Mercedes-Benz Wörth truck plant and completed by the subsidiary CTT (Custom Tailored Trucks) in Molsheim, France.

Mercedes-Benz is producing the new SLT in numerous variants. An outstanding choice on all fronts is the air-sprung Actros SLT with the spacious GigaSpace and BigSpace cabs measuring 2.5 m in width. The steel-sprung Arocs SLT based on the particularly robust Arocs Grounder is also available with the BigSpace cab as well as the StreamSpace cab measuring 2.3 m in width.

The air-sprung Actros SLT is available as:
Actros SLT 6×4, wheelbase 3400 mm or 4000 mm
Actros SLT 8×4, wheelbase 4000 mm

The steel-sprung Arocs SLT is available as:
Arocs SLT 6×4, wheelbase 3300 mm or 3900 mm
Arocs SLT 6×6, wheelbase 3900 mm
Arocs SLT 8×4, wheelbase 3900 mm
Arocs SLT 8×6, wheelbase 4200 mm
Arocs SLT 8×8, wheelbase 4850 mm

The Mercedes-Benz SLT is powered by the Mercedes-Benz OM 473 in-line six-cylinder engine. 15.6 l displacement, maximum 460 kW (625 hp) of output and up to 3000 Nm of torque are the credentials of the BlueTec 6 engine.

OM 473 in three power ratings

Output
Maximum torque
380 kW (517 hp) at 1600 rpm
2600 Nm at 1100 rpm
425 kW (578 hp) at 1600 rpm
2800 Nm at 1100 rpm
460 kW (625 hp) at 1600 rpm
3000 Nm at 1100 rpm

The engine brake attains an impressive output of up to 475 kW (646 hp). This enables the driver to keep even the biggest masses under control on downhill gradients without incurring any wear.

The engine power is transferred by the Mercedes G 280-16 transmission with PowerShift automatic gearshift – the only automated transmission with 16 gears on a heavy-duty tractor.
