BMW just released these images of the Vision EfficientDynamics Concept, which will be unveiled at the Frankfurt Motor Show in a couple of weeks. Conceived with the idea of melding the performance of an M3 with exceptionally low fuel consumption, BMW claims a 0-62 mph time of 4.8 seconds while scoring 62.6 mpg (U.S.) on the E.U. combined test cycle.
At the heart of the concept car is an advanced diesel-electric hybrid system, based on a compact turbocharged 1.5-liter, three-cylinder diesel engine. Altogether, the combined diesel-electric powertrain is good for 356 hp and 590 lb-ft of torque.
Depending on the driving conditions, the Vision EfficientDynamics is engineered to run exclusively on its electric motors, the diesel engine or a combination of diesel and electric motors. Maximum range in pure electric mode is estimated at 31 miles, with the diesel engine offering an additional 400 miles. Electricity comes from plugging into to the grid, or from regenerative braking and coasting. Recharging is estimated at 2.5 hours at 220 volts, or just 44 minutes at 380 volts.
