Volvo ReCharge Concept.
It's called the ReCharge, a concept car from Volvo to be unveiled officially next week at the Frankfurt Auto Show, it's a plug-in hybrid with a battery-only range of 100 km before you need to have the car's four-cylinder 1.6-liter Flexfuel engine kick in to power the car and recharge the battery. The ReCharge is built off a specially designed Volvo C30, meaning it's got a platform that doesn't need to be built from scratch -- boosting the possibility we could see something like it really hit the streets. The best news would be for the environment which would see "about 66% lower emissions of carbon dioxide compared with the best hybrid cars available on the market today."
Four electric motors, one at each wheel, provide independent traction power. Four-cylinder 1.6-litre Flexifuel engine drives an advanced generator that efficiently powers the wheel motors when the battery is depleted
