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.

Interesting that McLaren seem to have switched from radioactive green to white flo-vis. Any ideas why this might be?

I believe what you are seeing is a recessed area under the central splitter/tea tray designed to produce a low pressure area, thus add'l downforce. Not a big contributor by itself, but the positioning is as optimal as you can get so why not go for it?

This picture shows the flat floorboard.

It goes all the way to the wishbone as, seemingly, a flat plank.

In this picture there is a duct starting just behind the leading edge of the plank. It seems to be an exit from a hole through to the upper side.

tok-tokkie - I can't see it, only scuff marks. Could you draw on the photo to shows where you mean?

Hearing that McLaren won't be running their new rear wing

Seems odd to go to massive hassle and fly one out for LH then with no running since Friday they decide they dont want to run it.

Hamilton 5 place grid penalty for a gerabox change . Damn :(
“On the days when Hamilton’s insane alliance of guts, skill and derring-do appear capable of delivering the world it is easy to forget he is only 25, an age when it is all too common for boys to believe themselves men.”

It may have something to do with possible defective construction. Look at the photos of the end plates. The carbon fibre has delaminated very very badly. It looks as if the layers did not bond to each other. I have never come across such delamination before, and Mclaren should have serious concerns about their lay-up process.
