Inside Kimi Raikkonen's Monaco office

[satishsays.com]

On a track as tight and twisting as Monte Carlo’s you would expect a driver to have to put every ounce of concentration into steering his car. However, in reality he has far more to think about - the steering wheel doesn’t just steer the car, it also houses controls which he must constantly adjust to keep his car running at peak performance. When you see just how many controls there are, it seems incredible that he can remain focussed on negotiating the streets of the Principality without hitting the wall at the very first corner.

Ahead of this weekend’s race, former Monaco winner Kimi Raikkonen explained exclusively to us how he operates the numerous switches and buttons on the wheel of his McLaren MP4-21. See the image and follow us on an amazing tour of Raikkonen’s office:

From top:

+1 and +10 (green, far left and far right)

Used in conjunction with the MSG OK button (marked with a cross, right) to flick through car function menus, allowing the driver to override certain functions in the case of malfunction. The MSG OK button changes the respective menu of each of the two buttons.

PLS (yellow, with P, left)

Activates the pit-lane speed limiter when entering the pits.

PTT (red, left)

Pit radio button. Used to call the pit crew via radio communication.

DRINKS (grey, left)

Provides drinking fluid to the driver. Operates an electric pump to bring the liquid from a reservoir in the cockpit through a tube to the driver’s mouth.

TC OFF (blue, left)

Switches off the traction control. Mainly used during the formation lap to allow the driver to spin the rear wheels and generate heat in the tyres. Also used when exiting the driver’s pit position, allowing wheelspin, which deposits rubber on the tarmac, providing more grip during pit stops.

A and B (black/purple, black, left)

Used to change the traction control setting ,for hi revs and low revs. The various positions enable the driver to find the correct level of traction control interevention. The optimum level changes due to numerous variables, including the level of grip provided by the tarmac, the track temperature, the amount of rubber deposited on the track etc.

Lower left switch (with positions 2 through 8)

This presets the lowest gear for each corner, allowing the driver to change down through the gearbox quickly, without fear of selecting too low a gear.

C, D and E (black/red, black/white, black/blue, along base of wheel)

These switches adjust the car’s differential setting. These depend on various factors related to the overall set up of the car, the fuel load variation, low gear revs and high gears revs.

F (black/green, bottom right)

This button - a very important one - operates and changes the engine braking settings. As the race progresses and the car’s brakes become gradually less efficient, it is useful to be able to increase the amount of engine braking action.

G (black/yellow, right)

This button sets the rev limit for the engine - the highest revs it can reach in each gear before changing up. A higher setting allows the driver to extract more performance; a lower setting puts less stress on the engine.

H (black/orange, right)

This switch changes specific traction control and differential settings in accordance with the tyres being used - grooved, intermediate or wet - to account for the different levels of grip provided by each type.

R (red, right)

Allows the driver to select neutral and reverse gear.

OT (yellow, right)

The overtaking button. This temporarily increases the engine’s maximum rev limit when extra power is needed for a short period. When the button is released the rev limit returns to its default setting.

good info..

[Galley]

Don't most of them have an LCD screen?

[KzR]

Great info! The most used buttons are the gear changing ones, I think. The others like pit-line speed limiter are used at most 3 times a race only.

[Jimmy0]

Nice read, thanks for the info! :D

[SaLiVa]

So the big Mercedes logo in the middle is the honk/horn?

[Shibby]

The merc logo is mostly likey holding all the boards for the steering wheel.

Because don't most of the drivers when they get out take the steering wheel off and take it with them?

[Kerm]

I had no idea they have an 'Overtake' button..

Wow.

[S.MULLA]

last time i checked (ITV pre-race chat) one of those steering wheels cost near the 20k mark. and that was like 2-3 years ago- its probably in the 50k mark now.

Because don't most of the drivers when they get out take the steering wheel off and take it with them?

The wheel is removable because that's the only way the driver can get in and out of the tiny cockpit! Actually, if they don't replace the wheel immediately after they exit the vehicle after going off they are fined. The exception is if the car is on fire.
