I don't understand this. My Plaid Tesla has a motor on each of the rear axles, and it's direct coupled to the wheel. The already are doing torque vectoring.

Like all things in engineering, the trade-off's are critical. This article doesn't go at all into the pros/cons of the approach Tesla (and others) are doing as opposed to this approach.

As a general rule, if Tesla isn't doing it already I suspect it's either not economically feasible, difficult to manufacture, or otherwise has drawbacks they've judged signifigant.

... with that said, bring on the competition. The whole world wins with every improvement to transport and electrification!

I love this concept. It just makes so much sense in an electric vehicle to have Axial/Hub motors, something I'd expect Tesla to lead on tbh. should have been in the "Make it less dumb" step.

One motor her wheel but inboard like Rivian is a good idea. Hub motors on the other hand add a lot of unsprung weight and are not a good idea.

The idea of a motor on each wheel independent has obviously been considered, but what is often ignored is the sprung vs unsprung weight.

You could develop a pretty amazing off-road vehicle with independent electric motors in each wheel, but it would be a relatively bumpy ride.

Why do EVs of the current age look so douchie? I wouldn't be caught dead in one.

Tesla model S, X, and Y.

All Lucid models.

Mercedes and Ferraris.

Why can't they look neutral?

I want low-key, efficient, safe, and functional. And ideally more than 35 American miles of range.
