A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

Looks like it's coming from the central radiator outlet really.

Broken exhaust manifold is good explanation why smoke is coming out of the cooling outlet. And as I noticed the smoke is blue (maybe it's just picture effect). When smoke coming out of an engine is blue that usually means that engine started to burn oil and it's finised. Jenson said DIFF broke. So ehxaust plume could overhaeat that part. Also it could melt some other part of car in this area.

I think the tyres play a role on how where the exhaust flow . Working the sidepods , exhaust position and the tyres together is a possible way to direct the gases to the top of the diffuser.

well done, Richard. Now, back to technical matters. Has anyone got a reason for Button running different front wing and brakes at Bahrain? He did that last year as well, towards the end of the season.

There are also reports that Button was called in before the end of the race, so as to get a FREE gearbox change, when there was nothing wrong with his gearbox.

Button has traditionally run different brakes anyways. Brawn said that in 2009. He wants a more progressive setup that needs to warm slightly first before it starts braking. Maybe better suited too his easier, more gradual feeding of brakes.

Fwiw his car DID sound pretty sick - and they could've nicked 5th, so...i dunno.

Button ran a different front wing spec to Hamilton in 2010 Spa too... Lewis had a longer cascade and Jenson had basically an earlier version of this year's front wing, minus the r-shaped cascade. What caught me out is Button's front wing apparently generates more downforce and is less efficient in terms of L/D ratio, while Hamilton took the wing with less downforce and a better L/D ratio.

I wouldn't ever have guesed Button would use more downforce on his front wing. Maybe there is less of the front washing out when he's holding constant steering lock in a fast corner?

I think thats a very simplistic way of looking at it, the wings most likely have different characteristics that effect the whole car. They both struggled with oversteer in the race though.

I don't think the oversteer was a side effect of the front wings - more like cooked rears

Not arguing, but how do you know this?

I just read in f1 news that Michael Schmidt (no idea who that is) states that Macca has a new gearbox shape which will improve aero efficiency but requires a gearbox change. JB, by retiring, is able to use that new gearbox at the very next race, but LH will have to wait. 

Does anyone here know if they do indeed have a new gearbox for the car, and secondly, how long will LH have to wait to get that new gearbox as he just changed his recently? Will this place LH at a disadvantage to his team mate?

The gearbox casing is rumored to be for the Mercedes car, not Mclaren.

What's to say two cars can't have the same rumor?
