Admit it. The words “hybrid-electric vehicle” don’t bring the Porsche 918 RSR concept car to mind. This car, a version of the 911 GT3 R hybrid race car that stores the energy from regenerative braking in a flywheel, really flies. The charge accumulator feeds twin 75-kilowatt electric motors on the Porsche’s front wheels, boosting the car’s maximum power output to 572 kW.
