Compact retarder brakes during gearchange
Volvo's compact retarder is a gearbox-mounted hydraulic retarder that effectively supplements the vehicle's standard braking system. It suits most manual gearboxes as well as I-Shift. Since the retarder is attached to the propeller shaft, braking effect is also utilised during gearchanges.
Together with the latest generation of I-Shift, Volvo's compact retarder provides extremely high braking capacity.
Maximum braking effect with the compact retarder combined with EPG is about 670 kW, and with VEB+ it is about 865 kW.
