Valtteri Bottas of Cadillac and Gabriel Bortoleto of Audi will face grid penalties at the upcoming Mexico City Grand Prix. Bottas has received a 50-place grid penalty, while Bortoleto will incur a five-place grid drop for Sunday’s race at the Autódromo Hermanos Rodríguez.
Bottas’s substantial penalty stems from the installation of multiple new power unit components. His Cadillac car has been fitted with a new internal combustion engine, turbocharger, MGU-K, energy store, and control electronics. This cumulative penalty ensures Bottas will start from the back of the 22-car grid.
Bortoleto’s penalty is for exceeding the permitted allocation of control electronics units. His Audi will use a sixth control electronics unit for the season, resulting in a five-place grid penalty after qualifying. Under 2026 regulations, drivers are permitted three control electronics units, with an additional bonus unit provided due to the new power unit formula.
The 2026 Formula 1 sporting regulations stipulate that exceeding the allocation for any power unit component initially results in a 10-place grid penalty. Subsequent breaches for the same component incur five-place grid drops. Any driver accumulating more than 15 grid places in penalties is mandated to start from the back of the field.
Bottas’s season with Cadillac, a new entrant in 2026, has been challenging. The team currently holds no points in the Constructors’ Championship. Bottas has recorded eight retirements this season, frequently due to suspected power unit issues. His best finish to date is 13th at the Chinese Grand Prix.
The Finn’s future with Cadillac beyond 2026 remains unconfirmed. While teammate Sergio Perez recently extended his contract until at least 2029, Bottas is believed to be on a one-plus-one deal, with the team holding an option for 2027. Colton Herta is considered a potential candidate for the seat.
Gabriel Bortoleto’s Audi team, which debuted as a works squad in 2026 after taking over Sauber, sits eighth in the Constructors’ Championship with 23 points. Bortoleto has contributed significantly to this tally, securing points finishes including two eighth-place results at Silverstone and Spa.
This is not Bortoleto’s first grid penalty of the season. At the recent United States Grand Prix, he received an 80-place grid penalty for multiple power unit component changes, including a fifth internal combustion engine, turbocharger, energy store, and control electronics.
The Autódromo Hermanos Rodríguez circuit presents unique challenges due to its high altitude, situated at 2,250 meters above sea level. This results in a significant reduction in air density, impacting both aerodynamic downforce and engine cooling.
While turbo-hybrid power units do not suffer a direct loss of power at this altitude, the turbochargers must work considerably harder. This increased strain often leads to a higher rate of power unit attrition during the Mexico City Grand Prix.
Overtaking at the circuit can be difficult despite the 1.2-kilometer main straight. The reduced air density diminishes the effectiveness of DRS, and cars become less stable when following closely through the high-speed final corner. The first braking zone after the main straight remains a primary overtaking opportunity.
