I've copied the relevant bit of their press release below:

Brake Energy Regeneration (not available in all markets)

This technology ensures that the output from the engine is converted primarily into drive power, with electricity being generated for the on-board network only when the engine is on overrun or during application of the brakes. To achieve this effect the alternator is automatically disengaged from the engine while under power. Accordingly, the power the alternator would consume in the conventional mode now remains fully available for even faster and more dynamic acceleration.

An adequate supply of electrical energy to the on-board system is nevertheless ensured at all times, since the alternator is activated again as soon as the MINI returns to overrun or the driver applies the brakes.

The Bosch press release about stop/start is on their website here if anyone wants to explore that further.

Do all the new R56's have Brake Energy Regeneration (that are coming off the production line now)?
