Lando Norris will start the Belgian Grand Prix with a 10-place grid penalty after McLaren fitted a new power electronics unit — the fourth of the season and one more than regulations permit.
Team strategy ahead of upgrades
McLaren opted to take the sanction at Spa-Francorchamps on Sunday, calculating the long, fast Belgian circuit where overtaking is commonly easier poses a smaller competitive hit than suffering a penalty at circuits where passing is scarce. The timing also precedes a pair of major aerodynamic upgrades planned to debut around the Hungarian and Dutch Grands Prix that the team hopes will close a recent performance gap to rivals.
The replacement unit is a fresh specification of Mercedes-supplied power electronics — the control computer for the car’s battery — and was installed alongside the latest specification of Mercedes power unit because Norris’ previous component lacked reliability fixes added after a sequence of failures this season. Mercedes-supplied teams have experienced multiple issues linked to the part.
Reliability problems have dogged McLaren
McLaren’s decision follows a difficult run of reliability setbacks. Norris missed the start of the Chinese Grand Prix in March after a terminal failure of a power electronics unit. Another unit was removed after problems in practice at the subsequent Japanese round; although that Japan unit was repaired, it suffered a terminal issue in practice at Monaco.

The partial McLaren statement emphasises the team’s evaluation of the Japan-sourced unit but stops short of elaborating further in the text provided.
Championship context and consequences
On the standings front, Norris sits fifth in the drivers’ championship, trailing leader Kimi Antonelli by 82 points. McLaren have slipped behind their recent rivals in the pecking order as competitors introduced upgrades; the team hopes the incoming aerodynamic package will restore their competitiveness.
- Penalty: 10-place grid drop at the Belgian Grand Prix
- Component: Fourth power electronics unit of the season (one over the permitted allocation)
- Reasoning: Take penalty where overtaking is easier and avoid compromising Hungary ahead of upgrades
| Detail | Value |
|---|---|
| Drivers' championship position | 5th |
| Points behind leader | 82 |
| Number of power electronics units used | 4 |
| Grid penalty | 10 places |
McLaren judged that installing the upgraded Mercedes components now — accepting the grid drop at Spa — best preserved their chances to run a stronger package where overtaking is limited, such as at the Hungarian Grand Prix. The team’s recent reliability track record makes the move a calculated gamble: suffer a one-off track position penalty on a circuit friendly to passing, rather than risk impaired performance when upgrades are due to arrive.
The penalty reshuffles McLaren’s tactical approach for the weekend and adds a strategic wrinkle to Norris’ bid to climb back into contention. How the team and driver manage traffic and tyre strategy at Spa will be critical if they are to minimise the damage and preserve momentum ahead of the summer break and the promised upgrade cycle.
