Trying to extrapolate EV performance from hp based on ICE experience can be misleading. It's just a relentless, immediate hit. One of the companies at the SEMA show was using "eHP", which was some correction factor of their own devising. I think this motor in a Mini would be a really good performance level.
Junior rail dragster?
Is the q210 IRS or straight axle? If IRS would be cool to put into a f500 chassis. No gears, just like the snowmobile variant, all the torque. Only 67 ponies, but could this be grafted to a rear drive truck to power the front end for some kinda awd shenanigans? Race truck?
Cushman three wheeler of some sort?

How far do you think a 67 hp Power Wheels is going to go at full throttle before having some sort of catastrophic event?
The $50 Viper powerwheels I picked up to use for spare parts is body on frame. I think there's potential here
Driven5 said:I'm guessing there's a reason that when hooked to a 245v battery pack Toyota rates this rear end at 40kw, and when hooked to a 288v battery pack Toyota rates this rear end at 50kw. I'd like to see a proposal for how to get a 288v battery pack into a PowerWheels.
Ego outdoor power tools batteries are 56V, five in series gets you there, and you can use them to mow the lanw, blow leaves, etc when your kids aren't doing donut.
In reply to GIRTHQUAKE :
If you get bored enough to go look at it, could you take rough length width height measurements of the rear end assy?
I vote for craziest drift trike...
Won't whatever you are using to control the volts to the motor eat up power and efficiency?
In reply to the_machina :
Well, that at least ramps it up to like 4hp, from the 3/4hp (assuming zero losses) that a AA battery pack could provide. It still can't discharge anywhere near the stated 67hp rate though... In this case, that's probably a good thing.
Absolutely bonkers 2CV ?

The 1p batteries are good for 20 amps, the 3p batteries are good for 60 amps, so if you assume you're using the big boys, you get 60A x 280V = 16,800W. Fudge in some losses in the controller and you're at 20 horsepower.
Going to need some fat cabling for this thing. To get the full 67 horsepower it's going to need 180A of current (or thereabouts). BIG cables.
In reply to the_machina :
that's a good point. you're probably going to want to try and harvest the cables along with the rear end, if possible
In reply to the_machina :
I have not previously seen anything stating the big lawnmower batteries were good for up to 60A. Color me impressed. So it would take at least 15 of the big ones... While unlikely to fit in a PW, not that the rear end really would have anyway, still much better than I expected.
I've often contemplated picking up a write off hybrid Camry simply to create some kind of crazy 'AWD on demand' kind of project. Unfortunately, haven't seen one come up at the insurance auction locally, and the two spare LH body cars I have are headed for scrap to clean up the yard. One day...
Glad to see I'm not the only person with these thoughts though!
Thanks for the ideas everyone! I especially like the thoughts for drift trikes, autocross and special on-demand AWD systems. I'll go check it out in the hour.

Measurements? Sure!
In reply to the_machina :
Funny enough, a little while ago I pulled some hybrid cables out of a wrecked fusion that could work for ~$15; I think it's about 7 feet worth. Even the 12v is located in the trunk on the Fusion Hybrid, I easily got a hundred dollars in high-voltage cabling alone.
In reply to maj75 :
You're probably thinking of DC power; AC motors like this increase power and torque based on line frequency, which is why a 3-phase inverter is needed. Only brushed DC base speed off of voltage anymore, even Brushless DC (like in a power tool) use Pulse Width Modulation for efficiency.
In reply to maj75 (Forum Supporter) :
Modern motor controllers are something like 95% efficient.
In reply to dculberson :
And thanks to modern Silicon Carbide materials, it'll be hard to make them any more efficient than they already are- I think a Tesla Model 3 inverter is something like, 97-98% efficient.
Two of those motors in a toyota starlet would be a hoot for a commuter.
I have a strange desire for a manual transmission hybrid lately. I know it has been done dual motor & Honda had a manual transmission option on the crz. I don't think I want to deal with separate motors front & rear so that limits me to the crz system, trying to adapt one of the in Bell housing auto trans motors to a flywheel or using a belt drive setup like dodge does on the ram.
Any thoughts?
I've been eyeballing these rear ends for years trying to decide if it was worth going down the rabbit hole of installing one in the rear of my turbo escort. My turbo is a bit laggy for small-lot autocross, so this could be perfect supplemental power for an intermittent 30-45 seconds at a time. In theory I'd just kick it on anytime I'm at WOT and ramp down once I'm approaching full boost.
+100 ft lbs on demand could look something like this. Heck, maybe I could supplement my top end torque as well.
I got down to the yard a couple days ago- sadly I learned that the JY website is very slow to update, as the Lexus had already been crushed. Another will likely come around soon, but the best I found was a supercharger just lying on the ground.
I also saw RichardSIA posting small vintage racers, which might be a perfect chassis for it. Bugeye's also seem to come to mind as great chassis options for this. Hmmmmm
RichardSIA would LOVE it if you stuck an electric motor in one of his Sprites.
The Sprite used the same engine as the classic Mini, basically. I agree this sounds like a good option for those cars, they're light and weren't blessed with a lot of horsepower to start with. If you really want to get creative, get a Lotus 11 replica going.
Anyone have some photos and specs
How wide are they ?
And did the forklifts they came from use lead acid batteries ?
Thanks
OOOPS.......somehow I had forklift on my mind........better stop spiking the coffee.....
Picture of the forklift
Several pics of the motor here: https://www.diyelectriccar.com/threads/highlander-hybrid-and-prius-motors.86829/
