New BMW 3-series is imminent, previewing a new electric version of the long-running sports sedan.

BMW has revealed a new concept, the Vision Driving Experience , to hint at some of the systems that will be found beneath the sheetmetal of the electric Neue Klasse model.

The concept houses what BMW calls the "Heart of Joy ," an over-the-top nickname for the control unit that handles the drivetrain, braking, charging, regeneration, and steering functions.

The Heart of Joy is one of four central units in the car's electronics architecture and marks the first time drivetrain and driving dynamics functions have been combined into a singular unit.
