VIDEO: Bose suspension in action
Bose is most commonly known for its stereo systems and other home entertainment gear. The truth is that the company holds tons of patents, which it licenses to shrewdly fund research and development in a wide variety of areas, seemingly following the whims of Dr. Bose himself. The company has been working on electromechanical suspension systems for years now - I was even passed by one of their tricked out Lexuses while on my way up the hill to their Framingham, MA headquarters once. The video we've embedded after the jump shows the system in action, and compares it with a conventionally suspended LS400 with nifty split-screen footage. The results are dramatic, but we're curious if the cars were being driven at the same speed through the course. Be sure to watch to the end, where engineers let loose and jump the thing.
Thanks for the tip, fooman!

HOLY SH**
What the F***
Mutha FU**er
Is this for real? no details on how the mechanism works or is this a prank?

It's a pretty standard linear electro-magnetic actuator. Basically a coil and a magnet. This has been posted on auto-blog several times (although I'm not sure if this exact video has) and, like dan says, has been in development for years, which is how old this story is.

Yeah this video is pretty old...

I have been seeing this stuff for over a decade (maybe 20 years now) but nothing ever reaches production.

My prediction: it'll be a long time, if ever, before the system makes it to production. Like other commenters have said, linear actuators require gobs of juice - producing current weighs a lot when you factor in uprated alternators, heavier gauge wiring, and the weight of the actuators themselves. The cars do look weird in person, you glimpse one and immediately know that what you're looking at is one of their mules. The R&D on this system has likely already paid significant dividends to the rest of the company through technology sharing. Speakers aren't very different from linear actuators - now if they could just get their audio gear to sound like there's not a wool blanket over the speakers, they'd be all set.

Agreed Dan. There's the old saying: "No highs, no lows, must be Bose!".

Ugh, this is so old. Now that AB reposted it, that means an influx of people posting it all over forums...again.

why not the LS2/LS7? 7:19PM (9/21/2007)
GM started working on stuff like this (linear actuator suspension) in the 80s.
If you replace springs with linear motors (as they seem to have), do you realize how much power it will take to hold up your car against gravity? LOTS. And that power comes right out of your gas tank.
I think GMs ferrofluid suspension stuff is a lot more promising. Ferrari seems to agree.

No, they didn't.
The had to fit longitudinal torsion bars, and keep the dampers, while fiting the big actuator.
There was a cutaway drawing in motortrend a long way back. This was a hack to show off cool Bose tech.

So old... Unless we convert to 42 volt electrical systems like they have in Japan, I don't see how it would ever be possible...

You'd still need amperage Joe.
Joe K. 7:54PM (9/21/2007)
Hey thanks... I'm sure they thought of that... Now tell me about the risk of creating arcs with higher voltage. I'm just saying the more and more we start liking having all of these electric goodies in the cars with navs and touch screens and headrest screens and LED lighting and all of the goodies the more we need either multiple batteries or extra juice....

They have 42V electrical systems in Japan?! In their cars?! I remember when they thought this was the next big thing in the '90s, but it seems like manufacturers have all but obandoned the 42V car for the near future. I forget if it was batteries, or the complication of having redundant electrical systems at 12V and 42V while all the electronics suppliers catch up.
When I first read about the Bose suspension in Motor Trend or Road & Track 5-10 years ago, they said the people from Bose told them, "Watch how close we can stop to this plank." And then they did the last demonstration where they jumped it. That must have been a major surprise to see.

Woot, sorry I suggested it, I had not seen it before, sure it is old but it is pretty dynamic demo of a very effective active suspension. And the jump is pretty cool.

The Bose suspension on the LS400 has been around for years. This particular compilation may be new but some of the clips have been around for a while. More importantly, did anyone notice that the damn thing looks like a 4x4 from the side in order to accommodate all of the extra wheel travel needed to keep the body of the car static? It might be an amazing system but the car looks like holy hell.

My thought exactly. This would be a great set up for a SUV or a Truck. Great handling and off road performance.

That is simple amazing, I was laughing like a girl when it jumped over that small obsticle. Also Lotus was one of the first to make an active suspension except I believe it was pnuematic and was canned because of its weight. This would be awesome in larger cars but I can't see this being used in a sports car for many reasons.

HA, Ohh man thats priceless! The jump is amazing!!!
