I was enjoying a recent discussion with some kid who works in Europe for Monroe - in particular with suspensions for luxury cars. We got talking about different types of suspensions and i mentioned Toyotas 'active suspension' in the UZZ32. I was shocked by his reply saying there is no such thing and that Mercedes is the closest to developing this 'active' technology. I was swift to say, ummm dude its been in Lexus/Toyota since 1991 and it is 'ACTIVE'!! He replied, no its a semi active system for active only refers to a system which can predict uneven road surfaces. I.e Bose and magnetic suspensions.

So it got me wondering, what defines active and what do you think about this persons responses.

He has updated his definitions. Back in 1955 Citroen released hydro-pneumatic suspension which is the basis of active suspensions, and by the 80s they had passive anticipation where the rear wheels could prepare for a bump sensed by the front ones.

Active suspension itself is ordinarily regarded as active control of roll and pitch to keep the car flat during cornering, braking and acceleration, and the UZZ32 has it although it was not the first.

Your mate seems to be talking about anticipatory technology, which would involve something like "seeing" the road surface and steering inputs to prepare the suspension for a bump or a bend. That may be the new active but not active as it has been understood for the last twenty years. He needs a new word, something which rolls off the tongue more easily than anticipatory.

David, i think you hit the nail on the head. I was disappointed at his attitude as he seemed very arrogant and cocky.

I understand that a number of F1 teams in the early 90's had Active suspension. On F1 cars the active suspension computer would make 120,000 plus calculations in a single 4km lap. (about 30 calculations per metre)
Rolls Royce uses a similar set up and I have been told that the struts are cheaper to repair than a UZZ32.

Lotus was first in F1, in case anyone wants that settled.

He can be cocky as he likes, he still works for a company that makes struts.

I saw a film all about the Bose active set up ,the test car was a lexus..and the test track was lines of dips all out of phase ,.it was unbelievable
But they felt it would be unsafe as there were no feedback for the driver to know if he was close to the limit .

Dave i saw the same clip and it was very impressive !
Either way, im certainly not going to change my views on the uzz32 ACTIVE suspension because of some punks opinion.

Take a look at the Kiwi Corner thread about the dipshit who ripped all the active suspension out of his UZZ32, replaced it with adjustable coilovers, and took all the irreplaceable parts to the dump.

Matt, please, we need to give the poor idiot a break-he thought it was broken. Never mind the fact he had easily one of the best cars in the world and destroyed it.
It'd be nice if 32s had some pre-requisites before buying. Like "do you know what a 32 is?" and "can you be bothered fixing/getting it fixed"

Hey Matt,
That story nearly brought tears sic
Adam Brockman a newbie from perth WA only found out he had a 32's when he turned up at a club meet.
His story is in Say Gday -any other 32's out there.
Here is the BOSE clip

and
my all time favourite clip, 32 vs TT

Right there Joe, accept we can't give the guy a break! No way in hell - ignorant people like him piss me of to a good extent, I mean... 32 Shocks taken to a dump since they needed rebuilding.. NO!

As Matt says, they are irreplaceable. :-(

Well i was intending to buy a local 32 only recently but changed my mind at the expense of the possible repair bill should they break down. I also realised they're heavier and less fuel effecient than the standard Uzz31.

Mike, some people just dont know and innocently make mistakes. Im sure if he knew the value of his parts then he would have thought otherwise.
When i bought my first V8 over 3 years ago now i didnt know about the 32 and who knows i 'could' have ended up with one without knowing. I just bought the car because it looked nice :-)

Trust me Mike, if I knew this guy I'd give him bollocks till the cows came home, but sh1t happens. And 32's are a quiet achiever, so no wonder he didn't know

Yeah I know, thats the sad thing with 32's some people that own them don't know what they are actually dealing with.

Happens with a lot of special rare cars I guess out there.

Got to agree with David on this one, there is no current technology that can see the road surface and anticipate/calculate the suspension travel required for a given surface change.. just not going to happen, we will be riding in hover cars before that occurs, Anyone who owns a 32 is driving in the end result of a push to develop active suspension technology through the early to late 90's and up until recently was the only full active system ever produced in a production vehicle. BMW produced this
http://www.youtube.com/watch?v=wl2m5f16iyM
I do not know a lot about the system but it appears to active dance just like a 32 anyone know anything about its suspension system?
The more I work on the suspension and the more we learn about the 32's the more I am in awe of the technology involved and the execution, once the suspension has been o'hauled and good accumulators fitted etc these cars are smooth quiet and superb handling cars..

Just think, those poor old struts will be crushed by tons of old rubbish on top of them by now....

So sad, even though I have no need for them, it's just I find theres sentimental value in the 32's unique suspension system.

I actually need to check out John Lucas' immaculate UZZ32 when I get the chance. Probably some time next year once my Soarer is back on the road. Currently the engine is in a thousand bits! The starter motor is coming out tomorrow... shall be a very fun productive summer!
