Improvements for Volvo’s first long-haul hybrid truck concept

Volvo has unveiled its redeveloped concept for its first long-haul hybrid truck.

The Volvo Concept Truck was first announced in May last year, but it has since been adapted to make improvements to its aerodynamics and rolling resistance.

It also features reduced weight and a hybrid powertrain - which Volvo describes to be “one of the first of its kind for heavy-duty trucks in long-haul applications”.

It works by recovering energy when driving downhill, which is then stored in the vehicle's batteries and used to power the truck in electric mode on flat roads.

These improvements have helped achieve a 30 per cent reduction in fuel consumption and C02.

The trucks’ driver support system, I-See- has also been developed specially for the powertrain. It will analyse upcoming topography to calculate the most economical choice between the diesel engine and the electric motor.

In long haul transportation, the powertrain is estimated to allow the combustion engine to be turned off for around 30 per cent of driving time. This should save about five or 10 per cent of fuel. For up to around six miles, the truck is expected to have the ability to drive in full electric mode.

Lars Mårtensson, director for Environment and Innovation at Volvo Trucks, said: “today, long haul transport accounts for a significant share of the total energy consumption in the transportation sector.

“Using hybrid technology, the potential reduction in fuel and emissions is considerable and an important step towards reaching both our and society’s environmental goals for the future.”
