I think it had to do with the limitation on the number of forward gears a car
can have. The CVT has essentially an infinite number of forward gears,
easily exceeding the seven written into the regulations.

Inifinte, or one?

Ah, good point. My newsreader only shows 2 or 3 header lines (although if
I'm honest 'From:' is one of them <g>).

Is this what they call 'thread drift'?

As opposed to the Scots, with their "dread thrift".

Yup, that's exactly why I brought it up, because i remember that
Williams were about to introduce it back in the mid-90's, and that in
itself would've been quite a good development for road cars to benefit
from. A CVT that can withstand the torque of a race car could easily
work well with an economy car.

Depends whether you're steering into it, or controlling it on the
throttle.

Ta. Didn't know that.

Why banned?
Well, as somebody else said, it's because it violated the maximum seven
forward gears rule in F1. However, more specifically the real problem
was that it totally eliminated the gear-change pause, which would have
some tremendous competitive advantages for a team. In fact, earlier
this year, BAR was accused of having a CVT because their gearboxes had
some special mechanism that took the gear-change pause almost to
nothing too. So BAR had to show graphs to prove to the FIA that they
weren't using a CVT and in fact there was a pause between gear changes.

As an addendum to my original posting, I was thinking that in order to
accomodate things like 4-wheel drive, CVTs, electric motor assists,
they should increase the minimum weight limit of these cars by several
hundred pounds. I doubt they'll really need it, as the cars are so
light these days that they're actually adding lead ballasts to them to
make them come *up* to the minimum weight limit. Take some of the lead
ballast out, and put some real machinery in their place.

I really don't think all of the computer technology is the problem in
F1, rather I think it's going to be its saviour. Bring back all of the
launch control, active suspensions, traction control, ABS, etc. Get rid
of the wings!

I agree in some ways, disagree in others. F1 should be a leader in
technology, but I don't think it has to be relevant to a road car - some
of the technology you mention is already developed for the road and
would serve no purpose in F1 other than to increase weight and more
inportantly (apparently, according to the teams) costs.

What I want, is to see vehicles going as fast as possible,Man and
machine on the ragged edge and not artificially limited by Max for
"safety" reasons. Let them have TURBOCHARGED 3.5 litre V10s, massive
slicks, ground effect and small wings. Add a gearbox
that can be an auto, or semi auto controlled by a "real" gearknob (like
a Merc 1-series auto - real stick, no clutch) so at least the driver has
to change gear. Add ABS so they can brake even harder and later than
they do now.. then we'd see some serious speed and racing, because
they'd be able to overtake each other too!! 1500BHP, big slicks,
ABS...no traction control (it's already available on road cars,and takes
away some of the "spectacle" of F1) this is what we want, fast cars at
the forefront of technology!!!

As for the technology you mention, you make a good point but I disagree
- Take 4wd for example - what *is* the point in a road car in 95% of the
world? Unless you want a 4WD performace car - Scooby, Mitsu Evo etc -
and all these manufacturers have their 4WD systems pretty well sorted
from my own experience :-) For F1 it would just add more weight, a lot
more cost, and more pieces of strong metal to pierce tubs and people in
the event of a big accident..
I don't think active suspension adds anything to F1 either, or a road
car for that matter - again, those manufacturers who already supply
these options on road cars are top-end manufacturers who make cars 95%
of us will never afford:-)

Not too sure about CVTs though. I'm not sure any team would want to

One of the teams (I think it was Williams, cos I seem to remember Coulthard

it was banned by the FIA (I think).
