The new steering wheel was created to enable the mounting of an LCD screen, which shows the driver key information about the car for racing or diagnostics. It is a big step forward, as last year’s design was very simple and provided no added functionality. The wheel will give the driver more control over the car because it houses 2 shift paddles for changing gears without removing hands from the wheel. Also, it has 2 buttons on the front, which will allow the driver to toggle through displays, decide what key information they want to see, and activate launch control.
The front of the wheel is made from carbon fibre for light weight and rigidity. The rear enclosure, which contains all the sensitive electronics, adds strength to the wheel, and connects to the quick release for removing the wheel is made from a single billet of aluminium. Finally, the grips use foam tape to fill them out and add comfort.
The wheel is being designed by Antonio Brozičević and programmed by Charles Miller and Armaan Maniar Mohammed. The information it displays is read from the ECUs CAN stream, which gives us a constant stream of information to show the driver, from RPM to Water Temps. The decoding from the Data Stream is done by a microcontroller, which is on a custom PCB and is also designed by Charles.
