It does come with BER. From my post on press release:

Power units: opening up a new dimension of Efficient Dynamics.
Depending on the specific engine involved, the various models in the new BMW 5 Series come with a range of technologies and features serving to minimize fuel consumption and emissions. For example, one such technology is Brake Energy Regeneration, which concentrates the generation of electricity for the on-board network on the car’s overrun and brake phases.

Operating on-demand, the electrical coolant pump in the new BMW 5 Series 6-cylinder engines consumes significantly less power than a conventional pump and helps the engine reach its normal operating temperature earlier. The Varioserv steering assistance pump, varying the curve ring as a function of pressure and volume flow, avoids the usual increase in drive losses as a function of higher engine speeds. And when the driver and passengers do not require the air conditioning, the a/c compressor is disconnected to reduce drag forces to a minimum.
