I think it was Car and Driver in which I read about this today. Though I'd share. Typical suspension systems react to bumps in the road, The bose system is designed to be an active suspension.

The linear electromagnetic motor is used as a telescoping suspension strut along with a two-piece lower control arm.

A torsion bar spring connected to one end of the lower arm supports the weight of the vehicle.






Two vehicles of the same make and model are driven over a bump course. The vehicle on the left has the original factory-installed suspension and the vehicle on the right has the Bose suspension system. Both vehicles are being driven at the same speed.


Two vehicles of the same make and model are driven over a bump course at night. The vehicle on the top has the original factory-installed suspension and the vehicle on the bottom has the Bose suspension system. Both vehicles are being driven at the same speed.


Two vehicles of the same make and model are shown performing an aggresssive cornering maneuver. The vehicle on the left has the original factory-installed suspension and the vehicle on the right has the Bose suspension system. Both vehicles are being driven at the same speed.

Since this system still uses a torsion bar to support the load of the vehicle. Can we essentially think of these "actuators" to act like an adjustable shock? With the exception that the pitch and roll and various sensors eloctronically adjust the stiffness? I guess the question is do these motors have any dampening properties, or are they solid.

How far away could the electronically controlled air ride systems such as ART stuff, be from this "similar" style concept. If you can electronically set ride heights, could some sensors be added to allow the air springs to slightly inflate and deflate based on the movement of the vehicle?

Similar to some high speed trains which can "lean" into corners.

Just some food for thought, kinda rhetorical questions, but anyone got any input?
