Mercedes fitted George Russell’s sixth internal combustion engine (ICE) of the 2026 season at the São Paulo Grand Prix because earlier power-unit problems had left him needing another engine before the season ended. The planned change brought a five-place grid penalty. Russell said Interlagos felt like a suitable place to take it, though the available reports do not detail Mercedes’ full circuit-selection calculation.

Earlier failures made another engine necessary
Russell’s power-unit failure in Malaysia led to extensive component changes at the following Singapore round, where he served a 60-place penalty. Mercedes and Russell already expected another grid drop later in the season; São Paulo was his second grid penalty in four races.

The Brazil change was therefore presented as scheduled, not as a response to a newly reported failure at Interlagos. Mercedes fitted a sixth ICE, and the resulting penalty moved Russell back five places from his qualifying position.

Why take the penalty at Interlagos?
Russell said, “We felt like this was a good place to take it,” and said the team would try to make up ground. He also pointed to Lewis Hamilton’s recovery after a major grid penalty at Interlagos in 2021 as an example.

That explains Russell’s stated confidence about the venue, but it does not reveal every factor behind Mercedes’ decision. The key trade-off was clear: take the expected penalty at a circuit where Russell believed he could recover, rather than avoid the engine change.

What the penalty means for his starting position
The penalty is five places from Russell’s qualifying result, not a fixed starting position. If he qualified on pole, for example, the drop would put him sixth; from any other qualifying spot, the same five-place reduction applies, subject to the final grid order.

The engine change also came amid a difficult season for Russell. Mercedes teammate Kimi Antonelli had clinched the drivers’ title in Mexico City at age 20, while reporting described Russell as “a bit exhausted” after a campaign marked by repeated problems. That context helps explain the significance of another setback, but it is not evidence that it caused the engine decision.
