HOW TWEAKED LED LIGHTS NOW SHOW ENGINE STATUS ON 2026 F1 CARS

The FIA tested a new LED light system during Canadian Grand Prix practice, set to debut on 2026 F1 cars. This safety upgrade directly addresses driver feedback, as the old system's flashing patterns for the MGU-K's operating status were hard to differentiate at speed. With a more powerful 350kW MGU-K coming in 2026, clear communication of a car's energy deployment is critical for trailing drivers to anticipate speed changes and avoid potential incidents.

The previous system used single flashes for energy supply, double flashes for MGU-K disengagement, and continuous rapid flashes for energy harvesting. The revised system simplifies this by introducing specific colors: blue for the MGU-K supplying power below its maximum, purple when the electric motor is off and the car runs solely on the ICE, and yellow for super-clipping, where the motor harvests energy. This clearer visual cue will give drivers vital information on rivals' power unit status, enhancing overall track safety as F1 pushes towards its electrified future.
