New technology would integrate navigation route planning with energy management systems that operate the regenerative braking system.

BMW is working on a new dimension to its EfficientDynamics technologies that will integrate smart energy management with navigation systems.

The way the technology would work is simple: when drivers enter a destination into the navigation system the computer plots the most energy-efficient route and also schedules its energy management activities accordingly. For example, it could wait for a downhill incline along the route to use the regenerative energy from braking to charge the battery - a point where the load on the engine is minimal.

Such a technology would make models such as the 320d EfficientDynamics, a mild hybrid whereby the car battery that powers the on-board electronics is charged through regenerative braking, even more frugal than they already are.
