Mclaren Mercedes MP4-25

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

On a more serious note, I know its highly unlikely to happen, but I'd absolutely love to hear what Jense thinks of the MP4/25 at this stage in comparison to what he thought of the BGP001 at the same point last year. I've heard stories (Mika Hakkinen in 1998 & Jense in 2009 are the most notable to me atm) of drivers setting out of a car very early in testing and just beaming with confidence in the car, they can just feel it's a winner. I wonder if, over the next few weeks, we can gain an insight into this fro Jense - obviously he won't be saying "This car feels better than my car last year" but maybe his body-language might give us some clues?

The flo-vis doesn't really worry me too much atm. They aren't running random parts from last year's car to try and workout what's wrong with this one, their times aren't appauling, and on long stints I hear the times are fairly good. To me, having used flo-vis so much last year, it could well become a valuable tool this time around, just to look out for any tell-tale warning signs from last year. On the issue of using UV sensitive flo-vis, I reckon the only reason they might not be doing so is because when trying to look at the whole flo patters it must be easier to just look at very obvious lime-freen paint, than to run around with UV flashlights looking at one area at a time. Just my thoughts, I could be totally wrong lol!
Been thinking about the whole UV sensitive flo-vis thing and I think it may be because they're photographing the car for analysis at Woking. Might be harder to get a good photo of the UV paint.

That's a very good point...in order to get a decent picture of UV sesitive flo-vis paint/oil I guess you'd need a dark room with good UV lighting...guess you don't come across those all too often at F1 race track pit garages lol

Yeah, the 2 upper-stacked elements in conjunction with the camera winglets sure look like they're about to connect and become a bridge wing :o

I don't think they're going to attach to the camera winglets and not sure what advantage that would bring anyway.

From a few of the pics, it looks like the exhause fumes might just glance or miss the rear tires. Wonder if they are considering playing in that regard like Renault was.

The exhausts themselves go straight back directing air under the rear wing. The outlets themselves are shaped in the way they are because of the slope in that part of the car, and not to direct the exhaust flow.

Ahh thanks, so it was the angle in a few pics and the angle the pipe is cut at that makes it look like it exits sideways a bit.

Yup - got me at first, but from the right angle you can see the pipe itself buried in the bodywork, angled straight back.

So are we 100% sure the McLaren sharkfin is hollow and sending air to (or behind) the wing?

Nope, but it is definitely thicker than the other sharkfins, there are places on the car where air could be collected from, and there appears to be a slit in the back of the rear wing (that they also used flow-vis on). So whilst no one here is 100% sure, it is a logical guess from what we know.

so... would the driver's head/helmet be considered a movable aerodynamic device?

Think about it... He could move his head to the side on the straights which would "open the valve" to provide bleed air to behind the wing. And then, at brake onset, bring his head upright, shutting off bleed air providing maximum downforce.

I know it's nuts but think about it...

Interesting thought, but I doubt there is enough range of motion for the drivers helmet to make much a difference. They can just barely move their helmets to lean into a turn and look through it. Also, having a driver adjust their normal flow of head movement would have a big negative impact on their driving. Head position sets up a frame of reference for a driver's visual cues.

@ Fizzer... I get your point. But Barrichello does it now. IIRC, Schumacher and Irvine (?) did the same thing years back with the Ferrari to get more intake air.

Like I said, it's nuts but could be exploited if legal...

too lazy to look it up: do the fia regs say anything about helmets? i can just picture a newey-designed helmet with its own little front and rear wings :lol:
Best regards. I guess this explains why I'm not at my post!
