That's just a gear reduction mechanism. Inside a wheel. :mind=blown:
now...is there a reason that in that video they put it on the rear wheels of a FWD car? How does it add HP if installed on the unpowered wheels? I didn't notice them being installed on the front wheels.

I too still have many questions about it. Still looking into it.

Here's more of a description


Looks pretty damn impressive to me, if those numbers are real.

Cliffs: 50hp motor in each wheel. Installing these as kits does require the addition of a few batteries, which apparently is no big deal.

cuz it provides power lol, motor driven.

oh, I didn't realize they had their own motors, lol. But so...again, installing on a FWD car that doesn't have any kind of switching AWD system (like what Audi does), I assume you need some additional transmission work so that the car now "knows" that it's kinda/sorta AWD, at times?

What happens when you hit a rim shattering pothole?
I'm guessing a straight swap with another kit is the best option, but I'm sure in some cases only a handful of things might need to be replaced. The original install is apparently something you can do in under 2hrs.

I doubt it will last. what with road debris getting in there and chewing up everything.

the first video shows the motor mounted on car.

Uh, they are independently controlled electric motors - so no transmission coupling.

regardless, please explain to me like I'm an idiot how adding independently-powered rear wheels to a FWD car with a front LSD (exactly like that Type R in the video) doesn't completely fuck with the driving dynamics? I don't see how you can just pop these on without putzing around with the ECM and suspension and all of that whatever to make the car drivable. It's got to be more complicated than simply "I added power to the rear wheels!"

Is this just good for straight line speed or something? does it have its own computer that shuts off as soon as you turn the steering wheel or something?

It has it's own controller and gets info from the car's ABS system, most likely. Think of it as a one-way integration. OBD puts out ABS info if needed.
Sounds good. I imagine it probably is simpler than I think it needs to be, but I'm a dummy.

You are not a dummy. We can talk genetic engineering later so you can kick my ass. :p
As pointed out above; the sensor data and integration on modern cars is pretty impressive - that just needs to be forwarded back to the rear motors & brakes. I assume the motors are also connected for synchronization and possibly traction control. I would think this kit includes some sort of additional control pad to select some optional driving modes.

My bad. Didn't see they had a motor. Watched the videos, pretty cool stuff. I want to see how they cope with dirt on those rollers that support the rim.
