well i beg to differ, the main culprit is the rear wing and additional winglets just like in the article quoted by virgil. You see, a F1 car left a turbulence or dirty air at the rear of the car. As a result, the following cars' aerodynamic setup is compromised.

this is all because of FIA's own doing ... of finding ways to slow F1 cars ... now they face such problem.

let them have slicks again ... let them build cars that almost touch the ground again .... let them reach 400kmph on the straights ... aHaHhAhAha.

F1 is too safe nowadays IMHO.

^yep, i agree...

The ground effect, if I'm not mistaken, was banned long long time ago, before the front/rear wings was intro to F1. They are so effective that time that it was ban to make sure F1 is not too technical and lose the driver factor... Now they will ban TC too, for the same reason.

No TC + slick would have been great

Wings first appear on a F1 car in 1968 season. Ground effect was introduced in Formula One mid to late 70's.

oh.. my mistake then... must have mix up the time line. The site I read talk about ground effect right to it being banned before talking about wings, lol...

Valencia will host a Grand Prix from 2008 after agreeing a deal with Formula One supremo Bernie Ecclestone.

The race, to be called the European Grand Prix, is scheduled for late in the season on a newly-designed circuit around the Spanish port's streets.

The seven-year agreement is conditional on the People's Party holding power in local elections to be held this month.

The new deal means Spain will have two Grands Prix next year, with Barcelona staging the other.

Ecclestone has previously said that no European country should have more than one race.

The Valencia circuit will be between 4.1-4.3km (2.5-2.7 miles) long and its harbourside location is bound to draw comparisons with the Monaco Grand Prix.

According to Spanish media, Ecclestone insisted the race must be on a street circuit rather than the nearby Ricardo Tormo track in Cheste which hosts a round of the MotoGP and is also used for F1 testing.

Valencia's willingness to pay an estimated 26m euros (£17.5m) to stage each race as well as the boom in popularity of F1 in Spain, sparked by the emergence of double world champion Fernando Alonso, are seen as major factors behind the decision.

Barcelona's Circuit de Catalunya, where the Spanish Grand Prix will be held this Sunday, has an agreement to stage a race until 2011.

"Ecclestone has previously said that no European country should have more than one race."

ha ha ha... its all bout the money...

mclaren to use b-spec car in barcelona...new chasis,gearbox, front wing, side pod, floor, no winglet,no enjin cover,no rear wing...

lol... no more air turbulence

virgil : the san marino circuits' pit complex is still under construction, right?

It was taken off completely for the 2007 season. And i dont think it is under construction, maybe there is.... due to frequency of accidents that happen there and the history behind it.

But one thing for sure, it initiates the 1 country 1 GP. So if Spain were to have the Valencia GP, then that means that there is some conspiracy going on..
