BMW B58TU1 with 48 Volt Mild Hybrid: A closer look... 

I believe currently it does not, and this is upcoming for the models with the B48TU2 engine.

That's a good question and the honest answer is I don't know. Any added complexity over the standard internal combustion engine can be a factor.

Hi, there's no 48V mild hybrid system on pre-TU B58s. The regen indication of "Efficient Dynamics" on the instrument cluster is for the 12V battery and refers to BMW's now quite old system "Brake Energy Regeneration" (which charges the 12V battery with the alternator during braking, coasting or decelerating).

@@NoBrainerTalk So there's no power assist on launch then.....?

@@rodmanser7573 correct.

Hi there, do you mean in respect to cylinder deactivation system? If so, I do not.

@@NoBrainerTalk Yes, last time I doscovered a very interesting actuator on the cylinder head near exhaust cam consisting of two pushrods that act on rocker arm pin via som sort of pushbar.

Hi, do you mean trickle charging the 12V battery? If so, this is possible.

Not impressed ha? :)

Yep, its to save the world //politicians with subsidies
