Electric "conversion" of a VW Westfalia using a Model S platform

[Otmar]

Since the Model S needs to operate properly even in the case of faulty items, such as door locks, sunroof, etc. the propulsion system is probably quite isolated and should function in the absence of those items.

I'm pretty sure this is the case and the car will do its best to run and charge if it can do so safely.
On the other hand, I'm hoping to get over the air system updates and the current one is failing to stick. I'm guessing it's failing since I have a number of systems disconnected (SRS, HVAC, Stability control). It seems the simplest solution is to use all the original systems, even if the door handles just sit wired up in a box at first.

Zextraterrestrial: By early summer I hope to be meeting up with people at my Supercharger stops!

Is it possible that car is disabled in the Tesla database from getting updates to install since it's been totaled? The car may get the signal that an update is available but when it "phone's home" to get it Tesla doesn't send it, or something?

...Re TEG's point about too tall a gear ratio, this would certainly apply to an ICE where you have to optimize torque & power curves. With the MS these aren't really curves anymore, more like straight lines. Plus tremendous power/torque compared to Westfalia engine...--

But it would be like trying to accelerate in 4th or 5th gear all the time. I worry about stress on the gears in the gearbox at lower speeds under high loading conditions.

 

[JRP3]

It wouldn't be quite that bad, the gear reduction is still something like 9:1 I think, it would just be like pulling a trailer with some weight on it, which the S should be able to do easily.

Otmar, any updates? It's looking interesting so far.

Thanks,
Look for a new video entry on the blog in the next day or so, I just need to edit it.

Interesting progress; sadly, I can't help you with your parts troubles. BTW, how do you order parts from Tesla? Is there a parts listing you use? As far as I know, there is currently no service manual (and there might not be one ever released) and with missing parts, what can you do for finding part numbers?

You don't really need part numbers, because most parts are sold as complete assemblies. There are no individual parts sold like by most manufacturers(other than fasteners).

So far I've just called the local SC and spoken with the parts person. I hope to visit there soon.
I also have a list of part names, numbers and prices that was created for the body shop in NY that did the original estimate.

Otmar, when you get it finally completed, a picture of it charging at a SuperCharger should go viral
I'm not sure how Tesla corporate will react, but it is just a Model S with a different body.
Definitely tweet it to Elon, he'll love it

Just saw your blog; great project and I wish you best of luck. I spent six years in Corvallis so its cool to see that it is still a hub of tinkering and creativity.

How's it going Otmar? No updates for a while

How's it going Otmar? No updates for a while

It feels a bit slow but things are moving some, I am hoping to release a video update later this week.
Let's see, I got fresh 19" wheels with Michelins, Stripped down the passenger seat (I'll be able to lower it quite a bit), am working on spoofing the LIN bus that controls the front shutters and I plan my first visit to the SC in Portland tomorrow to order suspension parts.

Your project is one of the most interesting ones I have seen! I can't wait to see more progress, but at the same time I know how much work this is. I hope you find some sponsors and help. I really want to see this come alive!

Hello fellow Tesla fanatics. There have been quite a few cool updates to Otmar's blog if you are not following it directly. Check out the "Wreckla" below, it is now street legal and running around - complete with Vanagon Westfalia lights and indicators. I have to say that even the "Wreckla" is a cooler drive than most ICE cars :biggrin:

Here is the blog link:

Cheers!

I've been following this project... great stuff.

Even though I'll likely never do a conversion... or have a chance to see your awesome Stretchla, you are doing a great service to the Tesla community by sharing what you're learning. I already have several insights in to how my Model S works that I never would have had before...

Thanks for taking the time to blog up the whole project... really fascinating...

"Stretchla" ... sheer genius, or total nutjob???

I stumbled across this guy on YouTube ... apparently he enjoys camping so much that he spliced 2 Volkswagen campers together, limousine-style ... he also really likes electric vehicles, and would like to take advantage of the Supercharger network in his many cross-country trips ... so as anyone who's ever eaten a Reese's Peanut Butter Cup can tell you, when you're passionate about two things, the obvious solution is to combine them ... he bought a damaged Tesla, and is going to strip off the body and graft the camper shells onto the Tesla drivetrain ... gotta admire his ambition

Genious.

I've known Otmar's efforts over the years and I come down firmly on the genius side. Looking forward to seeing this vehicle in July.

I come down on the crazy side but then without those crazy people there would NEVER be any progress. We never advance unless we push the envelope and get our of our comfort zone. So my hats off to all the crazy one, and yes my wife would say I too am crazy. Who else would convert a 97 Jeep Wrangler to all electric drive or convert a 2004 Avalanche into a plug-in hybrid.
