Overview
- George Russell lost complete electrical power and retired from the lead of the Canadian Grand Prix on Sunday, handing team‑mate Kimi Antonelli a victory that extended his championship advantage to 43 points.
- The FIA and Mercedes have opened technical checks after paddock reports and team engineers pointed to a possible inverter or MGU‑K electrical failure as the cause of the blackout.
- Mercedes faces internal pressure over intense wheel‑to‑wheel duels between Russell and rookie Antonelli, with team principal Toto Wolff saying he will review how the drivers are managed while defending strong competition in the cars.
- The incident has sharpened an already heated debate over F1’s engine rules, as CEO Stefano Domenicali backed exploring a return to V8s by 2030 and drivers called for a higher combustion share in the 2027 formula.
- Teams are watching the rule fight for its business impact, with McLaren’s Zak Brown saying the team would only consider building its own power unit if a financially viable engine formula is agreed.
