Sorry if this has been asked before if it has please point me towards the explanation. (thanks Andrew)

One point that Adrian Newey made about the RB cars is that they run with a lot of rake i.e. height increases from front to back (whilst the nose is also high at the front wheels).

I am not sure what he really means by this does he means the relative heights of the front and rear wings?

What is the advantage of the high rake, does allow a cleaner airflow for the rear wing?

Finally the RB6 nose section looks different to other cars is there something going on with the high nose section and the curve at the front after the front wing?

many thanks

I believe "rake" refers to the angle between the vehicle reference plane (effectively the "plank") and the ground plane. Rake (as well as ride height) can be used to control front wing height because it is some way ahead of the front wheels, but the range of adjustment might be affected by the "tea tray" unless it (the tea tray) can flex....

the regs give a bit of a tolerance for each surface i think it has been reduced to +-3mm for 2011 .The regs give a tolerance specifically for production inacurracies and one has to go a long way explaining he is unable to produce the two surfaces coincidating with the reference and stepplane -which have to be paralell - meeting the numbers but not the paralellism....but there you go.
this little numbers game could allow for a considerable wedge between reference surface and step(sidepod/Floor) surface...

Whats the sense of a wedge?
You go for minimal distance at every point. If you want to rise the rear any further (assuming front is close to touching the ground) you just increase the rake of the total car and by this get the front wing lower to the ground + increasing front and rear wing angle of attack.
