Volvo plug-In hybrid concept includes flex-fuel engine

The ReCharge Volvo concept car is a plug-in hybrid with motors in the wheels, eliminating the need for a drivetrain. This increases efficiency. In addition, the small flex-fuel engine serves only to recharge batteries. This means it can run at a constant rpm and be tuned for optimum efficiency and fewest harmful emissions when running on ethanol fuel. This is perhaps the best application for biofuels such as ethanol.
