EV conversion Dual Tesla model 3 drive train front / rear motor swap ??

Post by hansvwtesla »

Hi Guys,

I am on the verge of starting a VW splitscreen 4x4 project and connecting some of the last dots...

I am not looking for endless horse power but I am looking for driving the Splitty on the beach and off-road so that the main reason for 4x4.

I think i can put it al in the van but I will need to use the Tesla model 3 front-motor in the rear and the rear motor in the front....
This is because the direction of the motors are mirrored and in this way I have the 'electric motor' in the position where I can create space.

So now my question !!
What could go wrong ?
The front motor will be more powerfull and most likely drive 70% of the car... and the rear motor will assist the car when driving offroad (losing traction ) and when I want to be ridiculously fast...

But wil there be problems in cornering or at high speeds... Having the rear motor in the front.... should make it a front wheel powered car... which it not really a problem i believe.... ?
My Last rear wheel powered VW with a tesla model 3 motor in the rear... was pretty dangerous to drive in the rain... a bit of heavy foot would make the back break out.... This should be better with front wheel drive...

Love to hear you thoughts

Hans

I don't think there's any real concern here - especially if you're waiting to use OI/EVBMW control for the M3 drive units, as you'll be able to tune/adjust power as needed. I'm not sure how the commercial Model 3 controllers would handle this situation - if you're using those, probably best to reach out to them. I reached out to one regarding their Model S 2021+ controller with technical questions for a planned build and they were helpful.
If at first you don't succeed, buy a bigger hammer.

I intend to use the EV-controls or ingenext controller.. So I can also manage the Battery pack. I can adjust the power but not individually per motor... I contacted these 2 companies but they did not have experience with this before... and they are a bit scared of making statements....
