Current 45e is 389HP/443TQ, the 50e will be 490HP/516TQ. This is going to be a very noticeable increase in power.
Those numbers are not what I was referring to but rather driving in electric.
Some analysis that has been posted from a European enthusiast:
Regarding the new E-Motor...don’t expect a big wonder. The new motor has just 20Nm more torque ( 265Nm vs 285Nm) .
That more power is just over 3000-5000rpm significant, as the new one can hold the torque up to 5000rpm ( old one up to 3000pm).
The question is how will BMW change the gear shifting logic. Currently the shiftpoint is at approx. 4000rm .
After that the torque is falling sharply down and it makes sense to shift into the next gear. It means, that if the ICE has to jump in ( e.g. kickdown) , then it hast to rev up to max. 4000rpm.
So if the new one will go up to over 5000, then it will be a huge jump for the ICE.
That range is currently not even accessible if the engine is cold ( max 5000rpm allowed).
I expect, the more electric power will be a game changer in the hybrid mode, but not in the EV mode.
Currently, the E-Motor could deliver up to 265Nm so it would be possible to reach the 700Nm in the range of 2-3000rpm, but BMW want a wide torque plateau, and therefore it's reduced to 150Nm ( which can be delivered at 5000rpm too).
The new one can put down 250Nm in the full range, and so you will have +100NM in Hybrid mode, which is more then noticable...
Yes, I meant that it won't make a big difference in the lower rpm range in EV mode.
265Nm at 3000rpm are 111hp and 285Nm at 3000rpm are 120hp. Shiftpoint is currently at approx. 4000rpm, so if you accelerate hard, the used rpm range is between 3000-4000rpm .
So in other words, if we would put that engine in the current 45e, we wouldn't notice a big difference. Above 3000rpm obviously looks better.
But in hybrid mode there is a 100Nm plus over the whole rpm range, and that should push down the 0-100 times by approx. 15% (4,7-4,8 sec)
