I think this has been done in VW buses, sand rails, and a Cobra - could be neat in a 914. And it would likely be a massive improvement over the rear suspension geometry as well.

Rear Track of a Model S is 67", Factory 914 is 55" - nothing some wide flares can't accommodate.

Wow! What is the piece in front that looks like a transfer-case? Does that need to go in?

Where are the dampers? I'm not seeing anything to control suspension motion?

Or some high offset wheels.

The model 3 rear end will probably be considerably narrower and cheaper in a couple of years when the market is flooded with them. NOT a bad idea! Looks like it'll fit under the rear trunk and there will be lots of space in the engine bay for a couple racks of capacitors or llithium batteries and the rest of the hardware and have room for storage on top of it.

That is the rear of car and Tesla motors have individual electric motors for rear wheels. So in Tesla cars there is no differential, but an electronic controller recognize that the vehicle is turning and adjust the speed of the electric motor.

I had a Tesla model S very early on was on the list for a long time as number 125 got my car in Jan 2014.
Eric and the boys from PMB got a ride in it when they picked up my 6 to go to Utah.
A bunch of guys going wee! (IMG:style_emoticons/default/aktion035.gif) and big smiles as well. Very impressive car, massive torque for days.

So this would take massive battery storage as you would need to go with a custom set up in the 914 Eng. area and up front to get any life out of it and what would you do for the power mamagement. You would need some real electrical talent to get it to run.
It could be done. Weight really does not mean anything to an electrical motor.

An early Tesla sport car that was a Motor in a Lotus with battery may be a better fit for 914s but where would you get one. I guess there have been some totaled Tesla's

Sounds fun but not an easy job to build. Did I say you need to be brilliant to work out the electrical part of this conversation? I have seen things from our member that is unreal as far as their talent.

That's the "transmission". Just a single speed "direct drive" to reduce the motor speed.

> Where are the dampers?

No shocks pictured. Easy to see where they would attach though.

AFAIK that has been solved now and there are controllers available to talk to the Tesla electronics now.

I wouldn't even try to. Just mount the motors in a cradle >> hybrid CV axles >> stock 914.

Probably need the Tesla ecu to run the dual motors correctly.

Lots of space for Li battery packs since you won't have a stock trans and huge Mach9? motor taking up space.

OK how much more for the batteries and the rest if you have a perfect 74 body reinforced for the torque?

I may be a player!

Cheaper than a 3.6 conversion, hahaha


I still have not gone for a ride in any model Tesla (IMG:style_emoticons/default/sad.gif)

I did get a ride in Otmars killer 914 electric conversion. Lot's of smiles in that car.

I can't really imagine 4000 lbs of motor, drive, batteries etc stuck on a 500 lb 914 chassis. I am sure those numbers are off, but still... doesn't seems like a good match.

But if somebody builds it, I wouldn't say no to a ride!
