Mercedes have just unveiled their design for the new F1 cars’ steering wheels and explained the changes made from previous seasons.
Here is Mercedes guide to the features of the 2014 steering wheel:
Left and right lights (FIA standard for red flag, yellow flag, blue flag) Top lights (Configurable, but generally used as gear shift lights)
There are a total of nine rotary switches on the wheel. Three are rotary dials, while the remaining six are configured as thumb wheels. The latter allow the driver to make changes to the settings without taking their hand off the wheel.
Menu Rotary (Middle) – Allows up to 15 different rotary switches to be able to change multiple configurations in one place, including tyre switches to adjust for the different compounds, for example
HPP Rotary (Right) – Used to control a large number of Power Unit settings, such as energy management during the race or MGU-K settings
Strategy Rotary (Left) – Enables adjustment of strategy settings during a session, including the way energy is recovered / deployed, for example
The right-hand thumb wheels are used for differential adjustment to change the locking torque at different phases of a corner: mid, entry and high-speed The left-hand thumb wheels are used as brake settings for both brake balance and engine braking: adjusting the pedal map and other settings
BB- / BB+ – Brake-by-wire management (adjusting the brake balance down / up) OT – The ‘overtake’ button
N – Neutral
+10 / +1 – Multifunctional switches, located in an optimal position
Radio – Activated the driver to engineer radio
DRS – Operates the DRS flap
Limiter – Engages the pit lane limiter
Marker – Used to identify a point of interest in the data as indicated by the driver
PC/R – Confirms pit entry by sending an automated alert to the garage.
This allows the crew to prepare for the arrival of a car, regardless of whether it’s been indicated on the radio that the driver is coming in
