What Happened
Mercedes did not bring its revised engine to this weekend’s United States Grand Prix at Circuit of the Americas in Austin (23–25 October 2026). Reports say it is also unlikely to be ready for the Mexican Grand Prix, which leaves the São Paulo Grand Prix 2026 as the earliest likely debut.

Mercedes has not confirmed that the upgrade will be available at Interlagos, nor that Russell will take any related grid penalty there. Reports describe the engine as not yet ready, and the team has given no new date.
Who Is Affected
The team is Mercedes-AMG Petronas Formula One Team, and the driver chiefly affected is George Russell. Russell has already used his permitted allocation of engine, turbo, energy store and control electronics, so any new component would bring a grid penalty.
The circuit is Autódromo José Carlos Pace, Interlagos, São Paulo. The race is the Formula 1 MSC Cruises Grande Prêmio de São Paulo 2026, Round 20 of the championship.
Dates And Times
The official Formula 1 schedule lists Practice 1 on Friday, 6 November 2026, from 12:30 to 13:30 Brasília time, which is 10:30 to 11:30 ET. Practice 2 follows the same day from 16:00 to 17:00 Brasília time, or 14:00 to 15:00 ET.
On Saturday, 7 November, Practice 3 runs from 11:30 to 12:30 Brasília time, or 09:30 to 10:30 ET, with qualifying from 15:00 to 16:00 Brasília time, or 13:00 to 14:00 ET. The race starts Sunday, 8 November, at 14:00 Brasília time, which is 12:00 noon ET.
Strategic Context
The Mercedes upgrade is being developed under Formula 1’s Additional Development and Upgrade Opportunities framework. Mercedes has not named a race for the debut.
For Russell, combining the upgrade with a planned component-related penalty could make São Paulo strategically attractive, but that remains speculation rather than a confirmed team decision. The Race reported in September that Russell’s penalty is being deferred to coincide with the upgrade.
What It Means for US Readers
For US viewers, the São Paulo Grand Prix starts at 12:00 noon Eastern Time on Sunday, 8 November 2026. Qualifying is at 13:00 ET on Saturday, 7 November, after US clocks go back on 1 November.
The race remains on the official Formula 1 calendar as Round 20 of the season. Practice 1 begins on Friday, 6 November.
What Is Not Known
Whether Mercedes will actually debut the upgraded engine at Interlagos remains unconfirmed. The team has not announced a decision on Russell’s power-unit components or any associated grid penalty.
No live prediction-market odds or named-institute poll specific to the São Paulo Grand Prix were identified in the available recent reports. The team has also not announced a date for the debut.
