Red Bull believes a hydraulic failure caused Max Verstappen's car to stop on track during second practice for the Mexican Grand Prix and does not expect to take a engine-related grid penalty as a result.
Verstappen set the fastest time in both Friday practice sessions and finished the day with a 0.153s margin over teammate Daniel Ricciardo in second. The next fastest car was Carlos Sainz's Renault, 1.233s off the pace of Verstappen, while both Mercedes and Ferrari struggled for performance. As a result, Mexico could be Verstappen's best chance to win since his shock win in Austria earlier this year.
