A series hybrid configuration was chosen as the most appropriate for the rally. A single 235 kW / 800 Nm permanent magnet electric motor was coupled directly to a 6-speed transmission which produced enough torque to negotiate the huge sand dunes as well as allowed a satisfactory maximum speed of 120 km/h on off-road terrain. A 60 kW range extender was in constant operation during the rally to maintain the charge level of the 52 kWh Li-ion battery pack from Winston Battery. Range extender’s petrol tank was sized at 240 litres, giving the overall autonomy of up to 1000 km. The team recorded 50% reduction in fuel consumption relative to the conventionally powered rally-raid cars. A significant contributor to this economy was the regenerative braking function of the electric motor, operated by a dedicated hand-lever in the cockpit.
