Bose don't just make speakers!

Insightful watch, and wait for it...yes, the car did an ollie!

That does look incredible. When I saw it jumping I was thinking April 1st though.

And perfect demonstration to all those budding inventors out there that just being technically brilliant doesn't make your idea worth anything!!

ie. these days, pretty much anything is actually technically possible, but being viable is about soooo much more than that............

It would be interesting to know what the weight penalty of the system is.

Do we think they used a 20yo car for the demos...? Or have Bose been trying to flog it since the mid '90s and not got anywhere yet...?

Yes, Bose really have been at it for 20 years.

I suspect the fuel economy penalty would be massive too (as it's presumably using power the whole time to suspend the car)

Technically interesting yet practically useless..... lol

I think the overall effect will be neutral - by the time they've substantially lightened the driver's wallet! smile

These systems will become commonplace with GPS enabling cars to prepare the suspension for a bend as you arrive at it. All part of the autonomous experience.

You'd hope it's not constantly using power. There's no reason the car shouldn't be suspended at normal ride-height by steel springs with the EM forces being used only when there's a reason to do something different. That way it should also be possible to use back-EMF to recapture some of the energy as the springs return to their natural state.

Your probably right, as on the "Bunny hop over the pole" in slow mo you can see the car first pull itself down against it's springs before leaping upwards maybe??


There is also the fact that cars that don't lean are HORRIBLE to drive, as the driver gets very little feedback of wheel loadings. Most road cars with active chassis are programmed to lean progressively.
