[Saba Sports News] The mystery behind George Russell’s sudden power outage during the Monaco Grand Prix has finally been resolved. Mercedes Technical Director Ross James Brawn exclusively revealed to British media before the Spanish Grand Prix that the cause was a short circuit in the power unit wiring harness, a millimeter-level defect that led to the W16 car being rendered powerless. Russell recalled the qualifying session, noting that when the car suddenly lost power in the tunnel, he initially suspected a cyberattack. At that moment, he had just improved his personal best sector time by 0.1 seconds before losing full power in the tunnel. This industrial precision “butterfly effect” cost Mercedes a critical qualifying position, dropping Russell from a potential front-five start to 14th place. Moreover, there was a risk of the issue spreading. Overnight, Mercedes initiated emergency maintenance, conducting reverse electrical scans on all current power units, with a focus on checking the connection points of the same batch of wiring harnesses. Over 300 connection rings were inspected. As a result, the production line has added three new anti-short circuit designs. This malfunction was deemed an unprecedented isolated incident, yet the team still replaced the wiring harness components of all spare engines for the Spanish Grand Prix. With rivals like Max Verstappen and Lando Norris introducing aerodynamic upgrades, the resolution of Mercedes’ electrical problems will significantly impact the championship’s outcome.
