This may seem like sacrilege to some but I've been thinking about doing this for sometime.
I love my 400SE but the one big issue I have is what do I replace it with at some point in the future?
A newer S Class seems to be the obvious choice but... Imagine an absolutely silent W140 with a 600 kilometre range between charges!
The idea of converting a W140 to full electric intrigues me. The car has plenty of room for batteries and the second hand Tesla parts are becoming commonly available.
I've got a background in computers and electronics so I'd be doing the work myself.
But to do a full conversion it would cost about $25,000 AUD (Using Tesla motors and batteries with an after-market controllers and monitoring equipment)
What do you think?
I saw a video of an Audi that was converted to full electric using Tesla batteries and motors.
Here's a screen grab...
I wondered who was going to want to do this
I was not about to turn-off everyone here ( Just like forcing you to here the music I like ) . I researched this about six years ago, but I did stay on top of this as I'm electronics guy buy trade. I tinker with everything even if it is not economically practical, but it is for my practical satisfaction. I will spend days weeks or months trying to figure things out-That is things get created or fixed- It was how I figured out to stuff our old 722.6's with new 722.6 internals-It is how I fixed my P0455 " Gas Cap Code".
I did figure out when these "Teslas" were under $10,000 USD, but then our buddy Rich-Rebuilds on YouTube let the whole world know how to rebuild a crashed for "Small Money". Well, those days are gone as these Model S Teslas are fetching $30k/$40k/$50k and the prime customers are Eastern European.
And in the USA their is some serious fraud with these Teslas from the two largest crash car brokers which is Copart and IAAI.
Read about the fraud :
The skinny with real auto crash auctions :
Good guy info
My take to make any conversion it would be to use as much Tesla components as it is just smart money
The EVTV guys had figured out to decode the CAN bus signals to drive the motor controller, and Damien Maguire out of the UK decoded the Tesla charger, so no need to buy extra stuff.
EVTV Motor Verks - Custom Electric Car Conversion Instructional Videos
The EVTV guys have piles of videos, and they have a two-week starter DIY class on how to make a conversion.
No need to get fancy with custom built stuff
I would find a way to use the entire rear sub frame from a Tesla, but one has to reverse engineer the dimensions of the W140 and Tesla, and model-it with Autodesk Fusion or similar software. You can get a two year trial with all the capabilities :
Training from this guy is excellent:
This can be done a smart way.
I'm not ready to try it yet, but I want to try it with a R129 as it is a smaller lighter car, yet has the weight carrying capacity identical to a W140 as both carry the identical engines all the way up to a M120. I would use Chevy Volt batteries as they are more safe than Testla cells, and more available without that high price because if I had to buy the individual parts, but I rather buy the whole crashed car...
Anyways, lots of info and video on this stuff. I spent months...
I'm taking little steps to get there. I'm going to learn to weld next fall to learn 3G/4G/Aluminum too.
I want to do it before I'm put horizontal in the box in the ground
Hope it helps,
