The Volvo Concept Truck is an update to its first such vehicle, launched last May, but it now has a hybrid powertrain, along with improvements to aerodynamics, rolling resistance and reduced weight.
The hybrid powertrain recovers energy when driving downhill or when braking, with the energy then used to power the truck in electric mode on flat or low gradients. In long-haul operations, Volvo reckons this powertrain could allow the combustion engine to be shut off for up to a third of the driving time. The truck can be driven in full electric mode for up to 10km.
An enhanced version of Volvo’s driver support system I-See has been developed for the hybrid powertrain. This analyses upcoming topography to calculate the most economical and efficient choice between the diesel engine and the electric motor, in addition to the optimal time to use the recovered energy.
The Volvo Concept Truck is “a platform for verifying several new technologies for increasing transport efficiency”, according to Åke Othzén, Volvo’s chief project manager.
“Some of these developments have already been introduced to our trucks, and some will be introduced in the near future. The hybrid powertrain is partly based on knowledge and experience from Volvo Buses’ hugely successful hybrid and electric bus.”
