New 2007 Dallara - what have they done?

[LeonBrooke]

It's silly for them to be adding all those small aerodynamic devices considering the fact that they'll be banned from F1 in not too long.

By the way, I think the IRL cars look cool. The Ferrari 248 F1 doesn't, in my opinion.

[Speedworx]

hey those cars look alright, it could be worse *cough*IRL*cough*

IRL road course car looks great, imo.

I can see them ruining GP2 soon. We all know overtaking in F1 is non existant because of all the winglets and things. Now they put them on GP2 cars.

Um......hello! Make F1 look like GP2

These extra flaps will have bugger all effect on the racing. The GP2 cars develop most of their downforce through ground effects rather than upper bodywork. Its why the racing is so damn good and why F1 should do the same.

...and it's why the 2007 Champcar will have most of its downforce produced by the ground effect. They've tried in F1 but the constructors won't play along.

Did they, when?

For 2005. Granted they reduced downforce from the underbody too, but let's not split hairs. Of course, it didn't quite have the effect of improving the racing...

If you look at the ideas for the regulations for 2007 and beyond they mention banning all winglets from the body, and reducing overall downforce by a significant amount.

It loos all right IMO, follow GP2 quite closly, and personally i don't see any problem with it, not major diffrences anyway.

The only changes for 05 that anyone talked about, as far as I know, were along the lines of what we ended up with: bigger rear wing endplates, bigger engine cowling, raised front wing, modified defusser design.Proper ground effects, like in CC and GP2, were never really mentioned and no one in the sport has really talked about it.

The new 2007 F3000 Lola looks pretty simialr.

The raised wing was supposed to reduce the downforce generated by it. The rear wing endplates weren't increased in size, what happened was they moved the whole rear wing forward. This reduced the downforce generated by it. Theoretically, a higher proportion of the total downforce was to be generated by the uderbldy in 2005 compared to 2004. However they managed to claw it all back so by the end of the year it was hardly different.

When they say "ground effect" in CC or GP2 all they're talking about is the diffuser and the venturi, same as F1 cars have.
