Valvetronic 6 cylinders <> iDrive

iDrive, the control for all entertainment and communication has been improved; now you can get to the main menu with a single button. Well, it still sucks. The Microsoft embedded operating system is not real time at all. Yes, it is very easy to use and learn, but requires too many actions from the user.

The 6 cylinders, on the other hand, has the fastest throttle response I ever experienced from a "non-M" engine. Quite frankly, that is a good move.
