Volvo Cars is introducing the Volvo ReCharge Concept, a plug-in hybrid with individual electric wheel motors and batteries that can be recharged via a regular electrical outlet, the company reports. Recharging allows the car to be driven about 100 kilometers (about 62 miles) on battery power alone before the car’s four-cylinder Flexifuel engine is needed to power the car and recharge the battery. Volvo ReCharge Concept makes its debut in a specially designed Volvo C30 at the Frankfurt Motor Show. When driving on electric power only, operating costs are expected to be about 80 percent lower than that of a comparable petrol-powered car. When driving beyond the 100 km battery range, fuel consumption may vary from 0 to 5.5 litres per 100 km depending on the distance driven using the engine, according to the company. The Volvo ReCharge Concept features a so-called “series hybrid” where there is no mechanical connection between the engine and the wheels.
