After several months of speculation and official teases for the past week, we now finally have all the details on the Vision EfficientDynamics Concept that BMW will show in Frankfurt in a couple of weeks. The speculation about the concept’s powertrain has gone in several directions, almost all of which were correct. The new concept is a plug-in hybrid with a three cylinder turbo-diesel engine. 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 EU combined test cycle.

There has been considerable speculation that future BMWs would go to smaller engines including a three cylinder. The concept uses a 1.5-liter turbodiesel that is essentially half of the fabulous 3.0-liter found in the 335d. The triple is rated at a hefty 163 hp with peak torque of 214 lb-ft. The engine is paired with a 6-speed DCT derived from the unit used in the M3 and Z4.

Adding fuel to the recent reports that BMW would not continue developing the two-mode hybrid system that will debut soon in the X6, the concept uses a new strong hybrid system. The new system is a further development of the mild hybrid that is debuting in the ActiveHybrid 7. As in the 7, a more powerful 33 hp electric motor is sandwiched between the engine and transmission. A second 80 hp motor provides drive to the front axle. The total net output of the drive system is 356 hp and 590 lb-ft of torque. Continue reading after the jump
