Keels (the difference)

Do you have any close ups of that? Would be great. Thanks.

Not really, but you can kind of see it in this photo:



They've basically taken the same suspension geometry as McLaren and raised the front of the chassis up a bit.

Very interesting. Thanks

I don’t get as to why all the teams in 2007 switched to Zero except Renault. I can see as to why Renault didn’t due to the previous year’s winning chassis, but as for the other teams I’m confused about the switch to Zero.

Renault's '07 chassis IS basically the '06 one. I'd expect them to make the switch for 2008.
Judging by the mess they've found themselves in, they assumed that the winning car from one season would still be good enough the following season - it wasn't and pretty much everyone ahead of them this season knew this well in advance of the boys at Renault.

As for the other teams:
Red Bull / Toro Rosso's car was designed by Adrian Newey - who came up with the Zero keel for McLaren.
Everyone else will have seen the 2005 McLaren, put it on their wind tunnel model and obviously seen the benifits and thus changed for the '06 or '07 season.
