In line electric motor in drive shaft?
So coming up with the idea that an in line electric motor may be able to be beneficial. My idea is to incorporate an electric motor on the driveshaft of a transverse engine layout with haldex awd.... regenerative braking to help with range would be all 4 wheels turning it.... is there a good choice of motor I could do this with? Just to help take the load off the engine a bit on acceleration?

I have only been aware of a similar project meant for longitudinal-engined RWD and 4WD.

Example? Two hub motors?

No I'm thinking a motor in the center of the driveshaft |

On a vw with haldex, you could put an in line motor in to drive assist the front all the time and the rears when the haldex unit is engaged.

Never seen anything that could relate to that. |

One issue I forsee is one of RPM. Electric motors tend to be more efficient and compact when they can operate at higher RPM with a stepdown. You'd probably want a gear or chain drive to the driveshaft, with the motor off to the side.

How to combine the output of both the ICE and the electric motor built-in to the driveshaft is what might be the most confusing part of it.

It's a ft/lb thing with the added effect on generating more back EMF at higher speeds. Won't see many hundred pole motors that run at 10,000 plus rpm.
