Mercedes’ Kimi Antonelli secured victory at the 2026 Belgian Grand Prix, extending his championship lead to 45 points. Teammate George Russell retired on the first lap following a collision with Ferrari’s Lewis Hamilton, a race incident that left Russell questioning the reliability of his car’s power unit after a loss of electrical deployment.
Power Unit Failures and First-Lap Chaos at Spa
The Belgian Grand Prix at Spa-Francorchamps proved to be a difficult outing for George Russell, whose race ended in the gravel trap on the first lap. According to Roadandtrack, Russell attributed his early exit to a critical power unit malfunction rather than the collision itself. The driver reported that his battery failed to recharge at Turn 1, leaving him with significantly reduced power as he climbed toward Eau Rouge.
“I made a good start, I made a great first corner, and I was tucked up right behind Verstappen. But for whatever reason, the battery decided not to recharge at Turn One. So I went around the first corner, the battery didn’t charge, and I exited the first corner 35% down. And because of that, because it didn’t charge, I also had a boost problem; the turbo didn’t sort itself out, so I had no power. I got to the top of Eau Rouge with 0% battery. Quite frankly, it was dangerous.”

George Russell, Mercedes driver
While Antonelli managed to overcome the deficit, the technical instability impacted the team’s overall performance during the weekend.
Antonelli’s Championship Surge and Ferrari’s Pit Incident
Kimi Antonelli’s win at Spa marks his sixth victory of the 2026 season, solidifying his status as the championship favorite. As reported by TSN, he now holds a 45-point lead over Lewis Hamilton, who finished fourth. Hamilton’s race was complicated by a five-second penalty for his role in the collision with Russell and a separate post-race investigation regarding an unsafe pit release.
During his pit stop, Hamilton was signaled to exit his box while a mechanic was still positioned near the car. The mechanic was struck by the front-right tire and knocked to his knees, though he was reportedly unhurt. As Sky Sports reported, Ferrari was fined €30,000 for the incident, with some of that amount suspended for a 12-month period.
Technical Insights from the Mercedes Floor Design
The retirement of George Russell provided an unintended look at the underside of the Mercedes W17, revealing design choices intended to maximize downforce. According to Motorsport, the crane lift at Spa exposed the car’s diffuser, skid block, and outer floor edge—components that aerodynamicists typically keep hidden.
This follows our earlier report, Verstappen Dominates, Perez Struggles: How Stroll, Ricciardo & Mercedes Stack Up in a Predictable but Nuanced F1 Season.
- Diffuser ‘hole’: An addition implemented this year to manage airflow expansion and reduce flow separation.
- Skid block: A resin-based plank used to monitor ride height; wear exceeding 1mm is grounds for disqualification.
- Outer floor edge: Positioned higher than the main body to comply with FIA downforce limitations.
These components are part of an integrated aerodynamic package designed to provide the rear-end stability necessary for drivers to maintain confidence through high-energy corners.
Looking Toward the Hungarian Grand Prix
With 11 races remaining in the season, the championship battle is entering its final stage before the summer break. The series moves next to the Hungaroring for the Hungarian Grand Prix.
