Axles

[bombmachinist]

PLEASE dont do IFS or IRS on the scout. Solid Axles provide such better performance while offroading (for the most part) and are normally way more durable when compared to independent suspension systems

Can’t divulge too much on this front at the moment. But… stay tuned, because we may or may not be dropping some forum-exclusive content here soon that would shed a little more light here.

And here I was thinking I could ignore the forums during Turkey Day... damn you guys! lol

Some like Rivian are doing "virtual" lockers using sensors and software to control multiple motors. Linked is a good (but long) review covering some light offroading in the Rivian R1T and R1S. The reviewer (Kyle Conner) pretty regularly says he would prefer a real locker.

Rivian R1S vs R1T

Not sure how finely rivian can control their pm ac motors whilst having vastly different loads on each, time will tell if they can improve things or not. Think switched reluctance motors would have been a better route for them as they are a stepping motor and should be more easily synchronizable, though rivian's future two motor variant may have physical lockers front and rear, hopefully that one will fair better in some of these situations but would lose torque vectoring. That may end up being the configuration some people are happy with.

The portal axle part, the reliability independent motor

Reliability in regards to independent motors or in-wheel motors? If the latter, keep in mind a traditional solid axle with a motor attached would be an unsprung mass as well.

There are types of off-roading independent suspensions excel at and losing the CVs will help them expand beyond those. A traditional solid axle EV on the other hand will suffer off road and in cost competitiveness (among many other things) because it will need a pretty large battery to have an acceptable range due to drivetrain losses, weight, and aerodynamic drag.

My guess is independent front suspension setup and ebeam rear setup like those from zf or magna.

If they're going IFS, give us a unique long-travel design with in-wheel motors, unencumbered by CVs and their inherent limitations.

That would definitely be an improvement. I don’t know Scout motors’ ethos, was only guessing ebeam and standard IFS because R&D effort would be low. I think if Scout motors wants to innovate and push the boundaries of what is possible in the off-road EV space, then going with all in-wheel motors (preferably switched reluctance in type) and a clean sheet suspension design makes a lot of sense.
