Are they driving with dry weather tires? Also what exactly did they change?

[daFt]

The only significant changes I can see are the side pod fronts are now cut in like Ferrari, Renault, and Sauber and the engine cover/airbox looks like it is extended a bit like Renaults.

Does anyone see anything else?

[TOPCAT]

I;d say we need a decent shot of the backend. Although given all the rain today I don't think that will come any time soon

great find perfectelise.

[daFt]

I'll stick with what I said above and add that it appears that the flip ups now have two elements as seen in the picture below. Although to be honest I'm not sure they weren't like that before.

Wonder why it took them so long to copy the red car's undercut sidepods. They just look right.

[zfh10]

thanks perfectelise.
the new Mac LOOKS the business....looks awesome. I just hope the performance can match the looks.

[Chevy II Nova]

Didn't the new Mac 'look like a winner' when it was the 18? And the 19?

[zango]

Looks like the car has a rather large gaping hole on top of the sidepods. I presume this is to vent hot air from the engine - sort of like the gills we have seen on the Ferrari, Renault & Sauber cars. Only in the McLaren case it is hole that points towards the little winglets on the sidepods: question is are they expecting the hot air to feed into the winglets and create downforce?

The winglets in turn have two wings vs. the one every one else has been using upto this point.

That is the Fire Marshall Access Panel!

It looks that the lamp on the rear end of the car a bit bigger than the curved shape what's in front of that. So the little piece of bodywork can behave as a little wing (as before) and the oversized lamp's edge can behave as a little guarney-flap?

Thoughts?

Looking at this picture , the rear tyre is completely worn out on the inside, but is relatively intact on the outside. Could this be a sign of some problem, with the suspension perhaps? Or has is something to do with the nature of the track and/or characteristics of the tyre?

That's a rain tyre, completely worn out. The inside of the tyre wears quicker than the outside, possibly due to camber. Nothing special.

I understand why - but wouldn't you be trying to maximise the contact patch of the rears for traction? Isn't that what opt is all about?

[VresiBerba]

Here's a little comparison.

[J. Edlund]

I wonder if they have done anything to stiffen up the chassi as this is rumored to be one of the reasons to the engine problem.

[Nav-D]

Here's a close-up of the rear wing.

Agreed.

I'm not technical, but feel that if they were trying to optimise the contact patch then they would want as much rubber on the road as possible, the picture shows wear on the inside of the rear tyre - wouldn't this mean that the contact patch is not optimised?

Where's scarbs?

Wouldn't that just be the case of not a perfect setup, they had run less than 50 laps on that day and less when the photo was taken, not enough time to get a good setup on a new car.

[scarbs]

I posted my knowledge on the MP4-19B in the subscribers magazine section. Overall very little externally has changed, the chassis has been laid up differently but externally is much the same. the sidepods and the detail of the bargeboards have changed, while the nose has been refined from the interim version used with the curved front wing. This is alot of work but result is probably only a small step for the team.

Heres a pic missed from the tech review...

Yeah, there was a suggestion above that McLaren were running OPT. It did not look like it to me either but then I am not an expert by any means and wanted second opinion.

I wasn't suggesting OPT was being used - just that I though the general idea for rears was to run them as 'flat' as possible in almost all circumstances. Maybe the flexy Michelins need some camber to optimise cornering? Can't be good for straight line traction and longevity with a pattern like that.

Isnt the engine cover changed ? I mean its alot longer until the drop towards the rear of the car compared to the MP4-19.

[Pong]

Have any off you seen the pictures of the engine cover on the mp4-19b?
It has a serious number of top-facing holes in it.
I do suppose they are intended to let air heated from the radiators out in places where the pressure drops on the top side of the car. Letting air out in these places will reduce upforce in this area and so increase total downforce.

Or am I wrong ?

[sblick]

The way to optimize the tires in the corners is to run some negative camber. This would account for the wear especially if they haven't optimized for the rain. Look at any Formula car and they run a lot of negative camber. If the track was pretty dry that tire would wear out very quickly also.

[TOPCAT]

After a serious amount of mileage, and some respectable times yesterday hopefully the package is looking a little more competetive. < Ever the pessimist.

[ScottL]

You know, that exhaust pipe tip just doesn't look right - like an afterthought or a piece missing.

Does Ferrari still blend the pipe tip into the top contour of the side pod? I remember hearing they had some heat problems with that design but it had aesthetic appeal.
