Hybrid Rally Cars Are Being Forced To Make Artificial Noise In Electric Mode

The FIA (Federation Internationale de l'Automobile) has introduced new regulations that will force certain WRC teams to fit a warning sound to hybrid rally cars operating in EV mode, reports Autosport.

Toyota, M-Sport-Ford, and Hyundai will be required to fit the safety equipment into their respective cars, which include the GR Yaris, the WRC Puma, and the i20 N. As per the new rules, the warning must emit a sound of at least 80 dB at a distance of around 6.6 feet from the front and rear of the vehicle and about 3.3 feet from the ground.

The new regulation will come into play on May 1, 2023, and stipulates that the sound must be active when the vehicle is in electric mode. Once the car is traveling more than 18.6 mph, it can be shut off.

In an attempt to be more environmentally responsible, these hybrid rally cars - which race in the Rally1 category - were introduced in the 2022 season and run on sustainable fuel. Fitted with a 100 kW electric motor, it is now mandatory for these vehicles to operate in electric mode when driving within the service park.

The regulations are, of course, aimed at improving the safety of spectators and team members. Following relaxed COVID-19 rules, the service parks are more populated than they once were, so it makes sense that the FIA is taking precautions to prevent any unfortunate incidents.

The EV mode is also required when the rally route enters an HEV zone. This was done to minimize disruptions to residents in towns and villages the cars must pass through as they make their way to different stages.
