Gen 1 does it, but the system only engages after warmup for stop start, not from the beginning. It also appears like it is able to add more torque fill across the power range compared to the belt mounted.
According to what I’ve found, the HP remains roughly the same between Gen 1 and Gen 2 (low to mid 10s depending on the vehicle). Torque numbers were never given for Gen 1, likely because it was limited torque added across the range due to where it was mounted. Having Gen 2 be trans mounted means the ability to access more torque when needed is possible.
That said, others have stated the torque fill is fairly limited. A good post I’ve found from xlover : https://f30.bimmerpost.com/forums/sh...14&postcount=7 |
could be correct
the formula is HP = Torque X RPM plus some constant (1/5252 for ICE, no idea what it is for the mild hybrid motor)
so if decent torque at low rpm then low hp but ... yeah ... who knows ... it sounds like it needs to be at very very low RPM. which does make sense, if it's for getting the car moving from standstill.
