BMW has released photos and more info on the development of the Vision EfficientDynamics concept which the brand is now saying it will take to production. The latest iteration of the Vision EfficientDynamics will also be put on display at the Leipzig trade fair taking place this month.

The Vision EfficientDynamics is a 2+2 sport coupe which runs on BMW's ActiveHybrid technology. The low slung car, at just 1.24 m tall, is designed for maximum aerodynamic flow and has a drag coefficient of just 0.22. It's a 2-door but BMW promises easy access to the rear passenger seats.

The core of the ActiveHybrid technology in the Vision EfficientDynamics is the hybrid set-up which couples a 3-cylinder turbocharged diesel engine with a 'hybrid synchronous' electric motor at the front and a "full-hybrid" engine on the rear axle, as BMW explains it in the press release. In the concept study, there were two electric motors, and one assumes that is what they mean for the "full-hybrid" engine on the rear axle. The electric motors run on lithium-polymer battery pack fitted longitudinally in the belly of the car.

Total output is a hefty 328 PS (241 kW / 323 bhp). The 0 to 100 km/h sprint takes just 4.8 seconds and consumption on the EU test cycle comes in at 3.76 liters/100 km (62.5 mpg US). CO2 emissions are 99 g/km.

Range on the Vision EfficientDynamics is 50 km (31 mi) on electrical power alone but a 24 liter tank for the diesel fuel extends that aplenty to 700 km (434 mi).

Speculation is that the Vision EfficientDynamics will come to be called the i100 or the i1.

The model is due for launch in 2013.
