In the latest episode of the BMW Unscripted series we have one of the automaker’s top engineers, Juergen Greil, giving insight into the development process and the general feeling towards the Vision EfficientDynamics green supercar concept, a vehicle that’s due for sale in 2013.

Hearing Greil speak, we get a real sense of the passion that’s going into the project, despite its green connotations and all that goes with it in the luxury and performance field.

You can also see a previous episode of the series, which features ‘Ring Queen Sabine Schmitz and details her life as the primary driver of the BMW "Ring Taxi" experience.
