Mercedes Arocs Turbo Retarder Clutch (TRC) and Hydraulic Auxiliary Drive (HAD)

The tailor-made concept for the SLT includes the turbo retarder clutch (TRC) combining hydraulic start-off clutch and retarder in a joint component. The TRC facilitates sensitive moving off and manoeuvring even at the lowest of speeds and as a primary retarder generates 350 kW (476 hp) of braking power. Together with the High Performance Engine Brake generating an output of up to 475 kW (646 hp), the TRC offers the ultimate in safety. The radiator, hydraulic system, the fuel tank with a capacity of 900 litres, the compressed-air chamber and further components are housed in the elegantly trimmed rear cooling tower.
