ClearMotion Bringing Bose-Developed Active Suspension To The Market

More than three decades ago, the audio specialists at Bose developed a revolutionary suspension system dubbed ‘Project Sound.’ Unfortunately, the technology never made it to production, but it may see the light of day after all.

The Bose system useds a modified MacPherson struct assembly complete with magnets, motors and controllers. Whereas traditional suspension systems use springs, shocks and control arms to react to surface changes in the road, the proactive suspension from Bose could read the road ahead and react accordingly. The result was an almost perfect-smooth ride over rough surfaces and virtually no body roll when cornering.

Last year, Massachusetts startup ClearMotion purchased all of this suspension technology from Bose and intends on making it viable for production. The company has already raised $100 million and is currently tweaking and reducing the size of Bose’s system to be only slightly larger than a traditional set of shocks. Dubbed ActiValve, the suspension uses magnets, motors and controllers just like ‘Project Sound.’

ClearMotion has been working with the likes of Bridgestone and Qualcomm to make the technology viable for production, and sees a world where autonomous vehicles will use its suspension.

That’s because the firm believes customers of fully-autonomous vehicles will demand smooth rides to allow them to do other things, such as work, while commuting.

    i remember seeing these videos back when this tech was first introduced. Kind of strange that Bose didn’t pursue further and release this developed tech themselves. I am looking forward to this for sure!

      I think they pitched the idea to several automakers back in the day but they deemed it to be too expensive.

        It was pretty expensive, too big to fit in current cars and much more havier. But it was the cost of having the best suspension in the world. Probably McLaren’s cars get kind of level of Bose’s one but begin smaller, lighter and expensive as hell. They can afford using that suspension but in 7 series or A8 it would be too expnesive.

    Good news. This is an incredible invention.

      And what do you consider the Delphi MagneRide suspension to be, after its been on cars and now trucks for 10yrs.

        The world is full of ‘incredible inventions’. Some more impressive than others. That said… I think the Bose system is more impressive.

        I’d considering it nothing next to this.

        Hope it doesn’t actually suck though.

          And no wind noise.

    I too remember when this Bose suspension came out. It was incredible stuff! Even had the ability to “jump” over bumps, keeping the body of the car completely smooth. But like others have said, it was too expensive. I also think it might have been a bit on the heavy side. With quite a few years past and huge improvements in computers, sensors and light weight materials and improved manufacturing, I think it’s more viable now. It’ll probably start in high end vehicles for lux and sport applications and trickle down from there. I really hope it catches on this time.

    … it is a fully electrified sytem. What’s the power consumption? I think in electric cars…
