A couple point for clarification:
-not in wheel motors but rather one motor for each wheel with a driveshaft...the trade off in ride and handling aren’t worth the ease of packaging
-I’m not necessarily going to reduce the rear track vs front track, however, narrowing the rear track won’t make the car inherently unstable. The rear will simply need to be balanced with the right roll stiffness vs the front to get good load transfer. Think of it as somewhere between a reverse trike and a car. The trike has no rear roll stiffness yet goes in a straight line just fine.
-longitudinal CG location affects load transfer front to read more so than straight line stability. Most stability is gained through caster and trail.
- for this car I’m aiming for as low a polar moment of inertia as possible to make the car more responsive to direction change.
