Electric Land Cruisers, yes, electric land cruisers.

First off, want to say thank you to everyone in the ih8mud community — been following closely and learning for 5+ years, and now that I bought a fresh-ish 200, decided it was time to join. Especially after I saw KDN165’s ongoing e-conversion project. So here’s the question/challenge: has anyone pulled off an electric conversion or hybrid conversion for a 200 series?

My gut says yes, because the folks on this forum have a ton of: (1) creativity; (2) will; (3) resources (whether money, elbow grease, connections, etc.). So would be very curious to learn the ropes.

A few crews are doing e-conversions on 70-series trucks, but they have relatively limited range and top speed. Tembo 4x4 in The Netherlands produces for the mining market (
Request for information about the Tembo 4x4 e-LV, the Electric Cruiser contact us)
; there’s a New Zealand team that’s working on an e-cruiser.

With a Tesla drivetrain, and a Model S or X battery pack, it should be possible to get range in the 200 mile window. Plus highway-level speeds — 70-80mph+.

Yes, a ton of work, a ton of money, etc., etc., but with DC charging (which includes possibility of solar arrays), one’s actual range ends up exceeding the 200-500mile range that’s possible on petrol/diesel currently (~200 if were talking stock 25gal tank; 500 if someone is running long ranger tank plus swinging jerry cans).

Before you’re tempted to write something “witty” like, “why don’t you buy a Model X instead?” — the answer is, the fun is in the challenge. Just ask the legion of modders who are doing various diesel converts in 80 series, 100 series, etc. So it’s not about, can it be done, but rather, let’s start working in this direction.

Tesla motor torque curves, 1million-mile motor over-engineered design, simplicity, etc. suggests a final rig that will weigh about the same as a current 200, but with lower COG, far more usable space, better handling, and potentially endless range.

How can we get potentially endless range? Just imagine a 6-pack stack of 4”x8” fiberglass or carbon-fiber sheets with solar panels mounted. At camp, they “unbox/unfurl” like a Martian rover’s panels, giving shade below, and netting 192 square feet of solar collection area. Depending on how long you break camp (2-3 days), it gives you enough juice to go another 100 miles or more.

Petrol is king today, but you can’t squeeze pine sap into your jerry cans when you’re high and dry. But solar charging, as insignificant as these trickles may seem now, is charging nonetheless. And charge = forward motion. Hence, potentially endless range.

I don’t know many other engineering challenges that are as faithful to the true spirit of the go-anywhere/tackle-anything machine we love and know as the ... Land Cruiser.

It’s 2018, so high-time we pooled our mental circuits together to show Toyota how to make the Land Cruiser as relevant and legendary in the 21st century as it was in the 20th. It’s time for a proper 200-300mile range, 80mph, 4x4 suspended, ultra-capable, E-Cruiser.

Let’s build it, folks.
 
Just to flesh out what’s meant by more usable space:

Imagine: (a) the Tesla battery pack sandwiched between the frame and the current body, acting essentially like a body lift; (b) Tesla battery modules detached from the Tesla battery pack and distributed into aluminum or carbon fiber boxes into the existing LC200 frame, including current tank mount location, etc.

This results in the engine compartment being freed of engine, tranny, radiator, air intake, etc. You’ll still need a small part of the engine bay for mechanicals (AC/Heaters, Transfer Cases, etc.). But the cubic meter/yard or so that’s freed up by the engine is one more cubic meter for your camping gear. Not too shabby.

Next, getting rid of the high-mounted tranny channel allows you to have more interior space in the cabin, if you want to reclaim it, including the possibility of a front bench seat, 3+3 riding configuration, a proper deep, functional console — instead of the puny console or San Pellegrino fridge many modern 200s come with.

What “remains” of the 200 with a build that’s this radical? Uhmmm, the LC’s legendary structural integrity in terms of frame/rolling chassis/suspension/geometry/cab — with only the drivetrain swapped out.

It seems daunting to think abt a build that’s this comprehensive, but, again, it’s not more or less difficult than so many of the diesel conversions, or heck, even suspension conversions folks have tackled on this forum — including custom fabrication of engine mounts, etc.

Long story short, it’s doable.

I like the idea, but redundancy tends to be part of my being... so I often ponder a Hybrid drive train. Running full electric in certain off road situations would make for great ability. Look further into the LS 600H and the Hino 195 Hybrids for more ideas.... I've got a few.

Thanks for joining in.
 
You're crazy. I love it. Subscribed.

An electric 200 is impractical for me unless it can recharge in a few minutes since one of the reasons I went with a full size vehicle was to pull a travel trailer across the country, but if it would work for you then do it!
 
A redundant electric “push” (FWD) or “pull” (RWD) motor would be a very smart addition to rigs like this. At tortilla-flat highway speeds, a little Civic/Prius motor would be able to easily *maintain* cruising speeds of 60-80mph at efficiency rates that are astonishing. So using standard gas power to get to speed, then switching to 2wd electric would be a really user-friendly range extending tactic.

Now, that being said, any sort of hybrid add-on and/or ECruiser conversion would be a whale of an engineering challenge, to add to the full-time 4wd capabilities of the LC, rather than just adding bulk/weight. But it can be done, it should be done, and by Jove, it will be done. So better to start thinking about “how” sooner rather than later.
 
I applaud anyone taking on a project like this. I myself would love to be involved, and only way would be to get paid to do it. Because the time and effort one would need to put in is tremendous! It will take a ton of engineering, along with integration. The latter being the hard part to get a useful and usable end product.

I've often thought about a strategy of siamese-ing a Land Cruiser with an EV, in 6x6 form. Keep the base rig, with full ICE drivetrain. Then an EV powered 3rd axle at the rear. Additional load capacity to handle the EV gear, along with more power from the EV powertrain. With some form of camper up top. This would be an incredible setup. Just think about the load capacity. Traction. EV augmented acceleration. EV regen braking down hill. All the pros of fuel powered long distance travel. The amount of juice from the traction battery for boondocking!

That's my dream beast.
 
See more photos starting at post 5126 in the forum sticky "200 Series Pictures Thread". I have no idea if the label means the LC is electric?

6x6 with the rear-most axle (the suggested electric axle) would be brilliant, especially if the third axle could be lifted if necessary, to give the standard LC200 departure angle, with the third axle’s tires serving as a de facto bumper. Done this way (with a swing-up third axle), it minimizes the need for balancing a full-fledged 6x6 suspension setup — which I imagine would be the most difficult task of an entire build of this caliber.

All-electric, all-wheel drive, off/ on road sport utility truck by Bollinger Motors, NY...

The Bollinger prototype rocks, Yes, but at $100K to $150K, this is pricey untested proposition. Versus $25K for a solid/straight used 200 series, $25K for salvage/restored/running Tesla two-motor axle assembly and controller, and another $5-10K for a functional battery pack. Plus a ton of elbow grease = $50-60K ECruiser.

Advantages of ECruiser versus Bollinger: Extremely tested/proven structural/frame/suspension setup, electronics and safety setup (ABS, Airbags, etc.). The ECruiser *proposed* build would be cheaper/safer/simpler than an entirely new model line. Then again, Tesla has been breaking that paradigm for the past several years, so nothing here is meant as a diss on Bollinger. They announced that when production pricing is revealed, most people would be “surprised” — if they can get it at the $50-$70K range, that would be a huge surprise indeed, though realistically we’re looking at $100K+ — which prices many would be ECruiser enthusiasts out.

What WOULD be a HUGE surprise and a huge boon to Bollinger brand and entire market presence is if they did what Tesla categorically refused to do — sell the infamous “skateboard chassis” directly to consumers.

IF Bollinger sells a working rolling chassis (frame/motors/battery/controller) NOT AS A CAR but as an enthusiast/experimental crate chassis — in the $25K-$40K range, that would be a HUGE market splash. Mudders would be tempted in droves. If you had a beaten/rusty but straight and reliable 100-series can that could just bolt on top of a brand new $25K Bollinger chassis, where the only thing remaining for you is to do suspension adjustments, you tell me you wouldn’t be tempted.

If Bollinger is reading this, and they release a rolling chassis for sale, they’ll have a Model T moment on their hands, akin to Tesla’s release of the original Lotus-based Roadster. Cruiser enthusiasts will be willing adopters, just because of the SMOOTH & POWERFUL torque curve, and the real (not theoretical) promise of endless range with solar charging.

Anyone have more info on the tracked 200 above, and can confirm whether it is, indeed, electric? Thank you.
 
Just looked at the Bollinger photos a bit more closely. A Bollinger (or other electric maker) rolling chassis + controller could theoretically serve as a base for 40, 70, 80, 200 etc. ECruisers — to say nothing of the thousands of 2000-era surplus Hummers that are cyclically coming to market.

The key point is to think of the ECruiser drivetrain in the most modable terms possible, going for plug-and-play component integration — keeping custom fabrication to the minimum possible. The closer the ECruiser is kept to its Land Cruiser DNA, the better will be the overall chance of further adoption, refinement, improvement, scalability.

We’ve all seen the photos of one-off creations like Arnold’s E-Humvee — those efforts are cool, but what seems much cooler is a closely-documented DIY demo-build for the ECruiser that will be accessible to the global Cruiser community. Replacing “twin-turbo-diesel” envy that some US-based mudders have towards global markets, and “big Petrol” envy that others feel towards the 5.7 motor in American 200s — with a shared appreciation for the intricacies, greater power and simplicity of electric drive.

If there’s ever been a motoring enthusiast community that can pull its collective mental and experiential power together towards a goal like this, it’s the mud-hating community here. A ton of potential.

Right now, the main goal is to see if anyone has already done this build using “off-the-shelf” Tesla motors/battery packs. If you know or can inquire about any stealth builds, even if the builder doesn’t want attribution/publicity (for registration/legal reasons) please do share any info.

What would be very helpful are any and all schematics, plans, wiring diagrams, photos, etc. — ESPECIALLY pitfalls, dead ends, and mistakes. With time, I’d be more than willing to start a separate website to aggregate all this info, so that it can serve as a central and well-organized knowledge base, but I hope this thread can serve that purpose right now.

Totally open to input, critiques, ruthless honesty, but please be open-minded and understand what’s motivating this. This thread is basically an attempt to build the Land Cruiser of the 2020s and 2030s, on a reasonable budget and a platform that we are all very comfortable tinkering on — and ultra-respectful of. Not trying to undermine the oil burners that have broadened our horizons and gotten us home safely. But the writing is on the wall: performance-wise, pound-for-pound, the ECruiser will beat out the Oil Cruiser, and it’s really fun to start thinking about the future e-powered direction of this legendary machine.

Some “big picture” strategic questions. The more input we can get on this from as many qualified tinkerers/mudders/mechanics/engineers the better, so please share this broadly.

Here’s another Tesla-based reverse engineered drive unit, appropriately named Alset (Tesla, spelled backwards):
EVTV Motor Verks Store: Tesla Drive Unit Kit, Tesla Drive Units, TeslaDriveUnit — this one has a Quaife Automatic Torque Biasing Differential — the EVTV crew is run by some hardcore coders who are always chasing the next big challenge, so it may be time to introduce them to the ECruiser concept. ;)
 
And a screengrab from our Aussie friends at Creative Conversions who seem to take special Down Under delight in chopping up perfectly good BRAND NEW 200-series Cruisers because, hey, they are Aussies and need that extra 650mm, 2 feet, of extra drivetrain/wheelbase/frame for their various “Ute” builds.

If you haven’t seen any of the builds put out by Jase and his motley crew of All4Adventure compadres, you need to make some popcorn and check out their YouTube channel (All 4 Adventure) WARNING: may inspire you to put an angle grinder or metal shears to your rig. I just love the audacity that crew brings to their build — they just go for it! Well done!!

For an idea of 6x6 capability — take a look at this video (
Patriot Campers’ 6x6 Land Cruiser 79 Series video review)
from minute 9:20 onwards. The whole vid is worth a look, but you can imagine the third axle as an independent electric axle adding push and added stability even in some challenging terrain.

For me personally, the 6x6 seems like overkill, but if it’s easier to “just” add on a fully electric axle by somehow figuring out an effective way to disengage the driveshafts on the regular 200 T-Case, so as to not destroy the tranny, then it may be the way to go.

Here’s another visual —

Pros of 3rd independent axle: (1) seems FAR more simple than decoupling the 4x4 and splicing electric motors to front and rear axles, and then somehow attempting to replicate the carefully balanced traction control mechanics/electronics that are standard fare on the 200; (2) original look; (3) more traction on rough stuff; (4) etc.

Cons of 3rd independent axle: (1) added weight; (2) registration hell if you intend to drive stateside depending on state; (3) being pulled over every time you get to new state by cops eager to “learn about your rig” and “educate you about local laws”; (4) etc.

So, for a true overland rig that’s going to be driven thousands of miles on family expeditions, it’s still a coin toss. On the one hand, the extra length and stability are always welcome. On the other hand, the cons are considerable.
