Should be "any front-wheel drive car." It looks to me that they replace the rear axle with 2 electric motors (one on each side). I don't think they could install this on a car with powered rear wheels.


I'm actually more concerned with how they've changed the design for rear drum brakes vs. rear disc brakes.

If I recall, that model Accord wagon had rear drum brakes.

edit: yep, it does have rear drums. I'm VERY curious to see how they intend to make this work for disc brakes, especially when the calipers have to wrap around that huge assembly.

The idea of rolling down the road and having a few magnets come flying off also scares the daylights out of me.


I don't see how the design could be adapted to disc brakes. The majority of vehicles sold have drum brakes on the rear, probably close to the 90% figure the person in the video mentions. Furthermore, cars with disc brakes on the back often have a cheaper trim version equipped with drum brakes, so reverting these back to drum brakes would not be overly difficult - swap out the mechanical bits and adjust the brake bias.


I would be very surprised if 90% of vehicles use drum brakes on the rear wheels (at least in the US). Every car that myself, my parents, my wife, her parents, have ever owned (except for one) has had disk brakes on the rear wheels. While I know I'm using proof by anecdote, I'm just saying I would be very surprised if it were even the majority.


Unless your parents are very young, or exclusively drove sports cars their entire life, that's almost certainly not true. Front disc / rear drum was a standard design for a long time.

You're more likely to notice disc brakes -- they are more visible from outside the car and require slightly more frequent maintenance -- so you may not be able to think of many cars with rear drums.


> The majority of vehicles sold have drum brakes on the rear

The majority of OLD cars. Modern cars are switching to disk brakes all around. The best design is actually a hybrid brake - it has a drum brake in the middle used only for the emergency brake, and the outer edge is flat for the disk brake.


In the video he said it should work on 99% of cars. The motor goes on the wheel hub; it should be able to go on a wheel powered by an axle, too.

To me it is the same idea as the electric bike retrofit kits by Bionx.
