Maybe the thing to solve this will be individual electric motors that are mounted to subframe as to not add unsprung mass but articulate with the wheel somehow.

Maybe the thing to solve this will be individual electric motors that are mounted to subframe as to not add unsprung mass but articulate with the wheel somehow. Or more realistically instead of huge angle on undriven wheels, a bit of an angle on all wheels. It’s been done for a while, in the 90s on Japanese sports cars and now German luxo barges.
- SigmundA 4y agoSomething like Ree [1] drives will probably be the future, minimizing unsprung while moving the drivetrain out to the wheels. I could see a top mounted motor driving a splined shaft that is also the kingpin with a sliding pinion driving wheel and you would have full 360 ability just have to keep friction down on the sliding pinion. Basically sliding pillar suspension with the pillar also being the driveshaft. Or just rotate the whole drive with suspension unit, just needs a much larger wheel well. 1. https://ree.auto/technology/ https://ree.auto/technology/

- _carbyau_ 4y agoThe Ree auto thing seems pretty cool. I hope they - or similar - comes to market. Having a car that can four wheel drive and steer with all the traction/anti-spin/abs etc smarts based on a modular component that can be replaced as required sounds great. Imagines upgrading to smart height adjustable suspension by replacing wheel modules. Though it'd be interesting to see what the aftermarket comes up with and the consequences of that.
