Champcars never had paddle shifting. It was only sequential gearbox with a
gear-lever.

I never got the real difference between semi-automatic, which is often
mentioned as being paddle-shifting, and sequential gearboxes. I think
semi-automatic systems automatically activate the clutch and blip the
throttle. Is that right?

Traction Control, stay legal for F1 are you serious???

Paul Tracy at 257mph:

I'll have to look again for the 265mph speed reached during qualifying
at California. It was mentioned a few times as the reason for slowing
the cars down.

No reduction in power, just that strip. Apparently the teams figured out
how to divert air flow around the strip, and/or used more effeicient air
foils / nose cones. CART was one of the few series where a different nose
cone and wing size were used depending on the speed of the track.

Other differences between CART/Champ/IRL versus FIA is that the
USA series allow underbody tunneling for more efficient downforce (FIA
uses skidboards), CART/Champ cars use turob-charged *** burining
engines, and the CART/Champ cars are more crashworthy than F1 cars
because they were over 200mph so often, which is why they are 200lbs
or more heavier than F1 cars. Now with the high speed ovals gone, I'm
suprised there isn't a trend in the rules to allow lighter cars.

Yes, I should have written "reducing boost". I am quite sure that boot was
reduced over the years. Power might have stayed about the same because of
heavy development from the engine manufacturers.
As you wrote the rest will be aerodynamic optimizations and maybe
tyre-development.

Yeah I allready knew all of that. Formula 1s underbodys with their "wodden"
plates are ***compared to the champcar ones.

Well there is only one chassis manufacturer left and the financial situation
of the teams is not the best. So no argument for lighter cars.
I think I heard a new chassis will be used from 2007 on.

Yes, of course. Formula 1 is all about hightech and too many things have
already been banned. People who want to see powerslides, manual shifting
etc. should better watch V8 Supercars, NASCAR and similar series.

They are also supposed to be the best drivers in the world...  It's set
to get banned anyway I think in 2008.  F1 is lossing both circuit
attendance and tv viewing figures.

Being hi-tech is all well and good, but when the racing is ***it doest
mean much.  Admitadly(sp) its mainly down to the cars dependancy on areo
dynamics that is causing the ***races but I would say most fans want to
the driver drive the car, not driver aided by the car driving the car.

WRC cars have three active diffs (but some teams don't have an active
centre diff), which do help to distribute power to wheels
electronically, but they certainly ain't 'no slip differentials'.

Ah, ok, thanks for explaining. I confounded those.
