    At the first day of this week's Barcelona test, McLaren have surprised the paddock with a radical reshape to their car's floor.

    Rather than a flat continuous floor inside the coke bottle shape, the MP4-24 has appeared with a curious cutaway section: a triangular section of floor is missing between the forward part of the floor, which follows the curve of the sidepods and a squared off edge just ahead of the diffuser.

    The rules demand a flat bottom underneath the car, with no part of the car visible from below. In recent years this cut-out would have exposed the flip-ups, but the cleaner sidepod lines allows the team to try this new floor shaping.

    A diffuser creates its downforce at two points: firstly at the kick-line between the diffuser\floor, then secondly at its leading edge.

    By effectively moving this leading edge backwards, McLaren are also moving the downforce it creates towards the rear. This may be part of a McLaren strategy to focus downforce production on the front wing and diffuser, as both devices are efficient at creating downforce with little drag.

    If these two devices can create enough downforce, then the rear wing can be smaller reducing drag and gaining speed on the straights.

    With no question on the floor's legality, McLaren may have stolen a march on the opposition at a time that many observers have been questioning the team's testing pace.

    That is really interesting Ron, thanks and great to have you back. Also how about the Williams and Toyota rear diffuser, you think the rest of the grid will be copying them?

    I am not a betting man, but if I did, I would bet that Ferrari and McLaren may leave the first four races in shock. Shock of having their butts kicked.

    By the likes of Toro Rosso, Toyota, and even Brawn GP. I don't know what to think yet about the Renault. And I hope for the benefit of the independents existence that Williams is on the podium often.

    And this will be a good thing. Sure I want to see Ferrari win, but if Massa does not prevail I would be pleased if Williams won the Constructor's championship and one of their drivers took the WDC. Or Toyota, or Torro Rosso, you get my meaning.

    Despite all the criticism of Max and Bernie, they may have found the formula to bring F1 up to NASCAR competition standards with these 2009 rules. Tony, as for copying diffusers or missing floors, those items are part of the aerodynamic package of that specific car, so adding a diffuser to a different design may not work. Same with the McLaren floor, may not work on another chassis. Frankly, although I believe both of these design features are legal, I would like to see them banned before the first race. The last thing F1 needs is another Michael Schumacher dominent season. We have to see at least 8 different winners this season, otherwise, a lot more people will lose interest in the sport. Just my opinion.

    Tony, I am not totally back, just waiting to see if this returns to being a Ferrari chat site or not.

    Even though there are now several drivers in F1 that can win, I think 8 is a very large number.

    how would that be fair on teams who had stayed within the rules and built a car with aerodynamics and suspension to suit these features ?


    i see what you mean - but im not sure i agree.

    imo what F1 needs is closer racing, more overtaking etc etc.
    it doesnt really matter if one man wins all the races if theyre exciting to watch.

    All good points Ron.
    My stand is F1 first (this doesn't necessarily mean FIA/Bernie/Max ), constructors second, and the drivers bring up the end.

    That said McC's and Ferrari will still be dominant unless Williams can bag a few early victories with KERS despite their sponsorship woes.
    As such once again this year I'm behind Williams as constructor
    and Nico as drivers champs.I dont expect miracles but I like to pull for underdogs. More fun that way.
    IMO Realistically Lewis and McLaren will take it.

    Agreed I'd be perfectly fine with Massa winning all the races :) as long as it's not decided when the lights go dark.

    It's much too early to suggest that Ferrari and McLaren will dominate. The cars are very different beasts from last year and there's no way of knowing whether those two teams have been able to build the quickest cars within the parameters of the new regulations. BMW and 'Brawn' perhaps did more development on this year's cars than most other teams and may well reap the benefits. I think we could have a few surprises and an interesting season.

    Interesting looking at the front wheels, at the outer fairings that have a leading edge scoop that's probably for better wheel/tire cooling that allows them to run more down force on the front without giving up much in terms of tire wear.

    Kind of strange...Ferrari used this first...CO2 to transfer tire heat to the wheel and an ingenious wheel cap that allows for tuning of temperature transfer to keep front tire temps in range. I thought McLaren were to stop using this tech or banned from developing it further? On of the big issues with McLarengate was the stolen Ferrari braking/cooling system.

    There are a lot of smart cats on the grid that looked at what Ferrari was doing and thought..."hey that's really smart, let's try it out" A pretty big departure from having Ferrari's engineering documents as McLaren had that allowed them to bypass tens of millions in development money that Ferrari spent that they did not have to spend.

    Kind of a shame that McLaren didn't get banned for two years with a permanent ban on using any tech found in the stolen Ferrari documents.

    This year, McLaren should be Mercedes McLaren with Ferrari Tech.

    i disagree...while never the fastest, Ferrari has been consistantly 2nd...that tells me that they've never gone for a ' time ' but rather are just working methodically through their program...they've been reliable and very quick over their long runs and i have a feeling that right now everybody who counts is viewing them as the favourites.

    Mclaren on the other hand...big, big aero trouble. they JUST started running the 2009 rear wing last week and monday they were running a new front wing with flow paint to see what the effect was...and they're still so SLOW...this to me is trouble not sandbagging. the new floor and other bits are an effort to fix something that wasn't working, not just an effort to conceal some highly secrective new bit.


    Bimmer has been sandbagging again this year but they took the ' wraps ' off this week.

    i think the consistency of the Ferrari and the Bimmer go along way to telling the real story.

    No one sandbags anymore. With drastically curtailed testing, no single team can afford to waste a day or even precious hours pretending to be that which they are not...there's nothing to be gained from doing so.

    Pre-season testing and times thereof are not to be taken into consideration in light of in-season competitiveness.

    Testing is just that. Comparing track times of various teams means exactly nothing. Teams today test their cars not against other cars but against their simulation data; they go out and try to match real world result with computational models.

    By that rationale you might as well ban everyone bar Ferrari, if you think there the only ones that don't cheat, you are aware of course if you stand still in F1 your history!

    Show me concrete proof that other teams have cheated, other than the vague no consequence of the supposed Renault and Toyota cheating. Show me concrete proof of teams other than McLaren cheating. And don't give me some vague idea that Renault did it or Toyota did it.

    Beyond that, the only teams that advance and don't stand still cheat? That's what you are saying.

    Show me concrete proof Mclaren used the info, your only kidding yourself if you think it doesn't go on, all it takes is an engineer to move shop, info goes with him. It's part and parcel of racing, but take the p!ss and get caught with your pant's down it ironically cost's a few quid.

    This infact is a grey area of leveling the playing field, like it or not.

    i disagree...and perhaps "sandbagging" wasn't the perfect word for what i was trying to describe but certainly the practice of keeping one's 'cards' close to one's chest (in a variety of ways) is very much alive and well in contemporary F1, IMO. having said that, i believe Bimmer has put their cards on the table this week and Ferrari will follow suit over the next day or two.

    for what it's worth, i think Mclaren is behind the eight ball right now...

    Disagree all you want, there's no reason for any team to be bagging sand or holding their cards close to their chest. Severely limited test days rules out tin-foil hatted legerdemain and bad James Bondian plot twists. Test days are limited so much that teams need to find out if actual data gained via testing corresponds to simulation data. There isn't a single team out there that's willing to waste a single lap on pretending to be what they are not.

    Test times of one team or fastest laps mean exactly NOTHING at all in terms of predicting future performance when the rubber meets the road in actual competition.

    Winter testing tells us nothing, and nothing should be taken from the times set by various teams.

    You need to answer my question before tasking me with another one. Got no proof? STFU.

    Further, do you have any concrete evidence of engineers moving and taking info with them? I mean, outside of our original arguement. To task further, do you have any concrete evidence of such happening today?

    Believe what you like, I'am not wasting time proving anything, the fact remains you can't prove Mclaren used the data, so I suggest you take your own advice!! and keep your head buried in the sand, best that way!!

    your post is a complete contradiction from start to finish...and who said they're out there wasting laps ? obviously they're not out there wasting laps...but thanks for the 'heads up' on that...

    then you say that "Winter testing tells us nothing..." SO...if we agree that they're not wasting laps, then what are they doing ?

    obviously they are running various programs, and no, they don't particularly want anyone else to know exactly what they are doing...
