 And what about the morality of using TC?  If the series uses TC, then
shouldn't those aids be allowed for online and hotlapping?

dave henrie

So yes you can enable that aid now inside NR2003, even online.

FIA - F1 allows traction control but not via a braking system, it has
to be done at the engine. It also doesn't allow an computerized
differential that would apply more force to the outside wheel (it
can take more force because of the increased downforce on the
outside wheel during cornering). Unlike a limited slip differential,
this would be a no slip differential, complex and not allowed
in any racing class I'm aware of. Last season F1 allowed fully
electronic control (clutch, gear box, ECU) for auto shifting
and launches.

FIA - GT1 class - unlike F1 which states what can't be done, is
a bit more clear that traction control is done at the engine (via
the ECU).

FIA - GT2 and lower classes, traction control not allowed.

ACO - Lemans LMP1, LMP2 - traction control at the engine (ECU) allowed.

IRL - not allowed.

Champ car (CART) - not allowed

The reality is that if that any race car with an sophisticated ECU could
implement some type of traction control, by limiting how fast rpms can
increase in each gear. Unless ECU's are banned by a certain series,
traction control is a possiblity.

I think such differentials are used in the WRC-cars.

True for last year as you wrote, but Auto-shifting and launch control were
banned in 2005. Traction control must not be used at the start until the
cars reaches 100 kph.

Yes, TC allowed.

Yes, no TC here.

Correction/addition:

LM900/675/GTP: no TC
LMP1/2: TC
LMGT1:  TC
LMGT2: TC

No differences in the ALMS!

Yes, TC was banned before the 2004 season I think.

Yes, TC was banned since Cosworth was the only engine.

Who could possibley check the ECU's to see if traction control being used
under 100kph / 62mph? Dumb rule anyway, hard to enforce, and do they want
a crash fest during the standing starts?. How many F1 tracks have sub
100kph hairpins anyway?

Someone's been doing their homework. It's hard to decipher this
information from the rule books, especially when in the cases where
the rules just specify what isn't allowed and don't mention what
is allowed.

The even brag about this, no traction control, (translation, we
crash more).

Champcars have never had driving aids, whether it be active suspension,
traction control, semi-automatic gears, etc.  I'm not a big fan of the
current NA Cosworths, but the older formulas with the turbo 4 bangers
coupled with the standard CART ground effect, low profile bodywork, and
actual stick shifts were some of the most exciting race cars ever made,
up there with GTX 5, GTP C, the Lotus 78/79, and the Mclaren MP4/4.

   Careful there JM.  Penske routinely ran TC it was finally allowed when
Toyota began complaining.  And the current Cosworths ARE TURBO.  Just de-
tuned turbos.  Same basic block that did 900+hp and 240+mph at California.  
Now with longevity and cost control, they are approximentally 750hp.    But
I agree, when Michael Andretti and Al Unser Jr were challenging the older
drivers like Emmo and Rahal and Mario...the racing was great.
dave henrie

That was 240+mph average lap speed during qualification. Top qualify speeds
were 265mph. During a race at Michigan, Paul Tracy recorded a trap speed of
257mph. They slowed them down after that year (1997?) with by adding a drag
inducing strip to the rear spoiler. There's no point in this anymore, as they
don't run on high speed ovals anymore. Down to just 2 ovals, mid-sized ones,
the rest being road and street courses.

Toyota Atantic series specifies a no lift sequential shifter, don't the
Champ cars use a similar type shift setup?

Yes, very hard to control that for the FIA. But they try to but I dont know
how.

When the full launch control was allowed we had much more cars that stalled
on green.

I think you misunderstood something. The rule that TC must not be active
under 100 kph is only for the start. After that TC is allowed at any speed.

Traction control was allowed at least for 2002.

The Cosworths are still turbo charged, but with reduced pressure and a rev
limit.

Full ACK

Stephan

Yes, that was fanstastic. I remember watching it on Eurosport. Mauricio
Gugelmin took the record in 1997 and was beaten by Gil de Ferran in 2000.

I was searching for those topspeeds for quite a while but could never find
them. I only knew they were above 400 kph but not more. So where did you get
the numbers from?

Yes, they slowed it down consistently after the 1997-season. But Gil de
Ferran beat Gugelmins record in the 2000 qualifying at Fontana. I still
dont know how they could go faster in 2000 with all those regulations
reducing power and increasing drag.

Thats bad I think. Champcar always was about the oval/road-course-mix. Too
many road-courses today.

Yes, in Champcars you dont have to lift.
