The best part:

Exactly my point.. even fast, overpowered cars lose some oomph when the
A/C cuts on. Can you imagine losing even a third of that every time you
hit a pothole?

When you regain consciousness from having whacked your head on the roof, fumble
around for your dentures somewhere on the floor, you'll really enjoy the
ability to achieve a fast getaway from the rubberneckers lining the sidewalk --
all of whom will appreciate that brief but illustrious moment of comic relief
you have managed to bring to their dull, boring existences. Who says the era
of the Keystone Kops is over?

Uhhh I don't get it....does Bose think they invented active suspension
or something? Is this for real? Can you actually buy this setup?

I don't see how you can manufacture something like this without it
being specifically engineered for a vehicle.

Most higher cost/performance modern vehicles have reached a very good
compromise between cornering stability and ride quality, to me active
suspension is just another gimmick to fail when the vehicle gets
older.

Plus the calibrations for these things are all wrong when the next
owner of said luxury barge cans the stock wheels/tires and puts on a
set of 22" chrome dubs with 25 series tires anyway.

It doesn't matter if they think they invented it, if they can get other people
to think they invented it.

True, although with modern computer systems, it is possible that most of
the vehicle-specific stuff can be put into a replaceable ROM. But Bose
has a very good relationship with an auto maker as a result of supplying
sound systems to them.

But it was so wonderful on the Citroen, except when it was exploding or
spewing hydraulic fluid into the passenger compartment or suddenly collapsing
at highway speeds.

Just a matter of changing the control gains with fancy aftermarket ROM kits
that you can charge a fortune for!

I hear, few if any non-sales types who have been at a Bose salesmen's
meeting.

I recall seeing an article, probably in EETimes, that TI was doing
some sort of active car suspension with DSP's.

I noticed that a car's (1991 Toyota Corolla) suspension has a much
lower resonant frequency when the car is fully loaded than when it
just has a driver (not to mention the big reduction in uphill
accelleration), surely the code could dynamically handle this (though
perhaps not the lack of acceleration) without having to change ROM's.
And nowadays it should just be a flash upgrade, just plug this
programmer into the appropriate jack and push the button.

Now that's excitement no other vehicle can offer...

As if they didn't charge enough for the wheels and the "We Finance"
interest rates.
