Volvo is showing off a new type of hybrid concept car and it seems pretty promising. The concept is currently called "ReCharge" and will drive 62 miles only off of electricity.
Then, when the fuel cells are dry, a four cylinder flex-fuel engine starts up and drives on gas, while also recharging the fuel cells.
This is a great concept because it allows for short drives entirely on electricity, but allows drivers to take longer trips and recharge on the go with the engine.
No word yet on when this concept could become a real car, though.
