Overview
- Mercedes acknowledged a fleet‑wide software fault that triggered the energy‑harvesting limit at Turn 1 during the Belgian Grand Prix, producing zero electric boost down the Kemmel Straight and leaving George Russell vulnerable to an opening‑lap clash that ended his race.
- Strategic development director Simone Resta said telemetry first showed deployment differences at Silverstone and that subtle driving‑style factors contributed, but the Spa failure was specifically caused by a software issue that affected both Mercedes cars and is still under investigation.
- Team principal Toto Wolff publicly defended Mercedes’ power output, saying he believes Mercedes has the most powerful power unit, comments that have prompted calls for scrutiny of the FIA ADUO engine ranking that placed Red Bull top and Mercedes second.
- Kimi Antonelli converted the weekend into a win and extended his championship lead to around 50 points, while Russell left Spa with a DNF and a furious team radio tirade about losing battery power on the straights.
- Under the 2026 rules the cars must balance an internal combustion engine with a 350kW electric system, so software or harvesting faults directly cut straight‑line speed; Mercedes must patch the code before Hungary to limit damage to its drivers’ title bids and constructors points.
