Cadillac’s improved pace at the Austrian Grand Prix was overshadowed by another reliability setback, as Sergio Perez and Valtteri Bottas both retired within the first four laps because of overheating brake failures. Bottas stopped on lap 2 and later returned to the pits with smoke coming from his car, while Perez’s race ended after four laps. Perez said the brake problem was unacceptable and the team could not have those kinds of issues, and both drivers said Cadillac needs to start finishing races.
The double DNF cut short a weekend that had pointed to progress for Cadillac after it brought a major upgrade package to the Red Bull Ring. The team showed stronger qualifying pace, with both cars knocked out in Q1, and Bottas said the new sidepods and floor made the car feel more consistent. Cadillac was still running nearly a second faster than Aston Martin, and Perez said the team had been competitive enough to be in the mix with Williams before the failures.
Reliability issues had already affected Cadillac from Friday practice onward. Perez lost track time after an electrical issue in FP1 and FP2, and Bottas had a sparking and then burning front floor tray caused by a build error. Perez said the problem did not appear in practice and seemed to worsen with race-day heat and traffic, while Bottas said there was no warning before the brakes overheated almost immediately. Team principal Graeme Lowdon said the car’s outright pace has improved, but the reliability problem must be solved before Silverstone, and Perez said he expects progress by then.
