Sergio Pérez previews Spa-Francorchamps: ‘Your heart beats faster’ ahead of Belgian GP

Sergio Pérez has warned that the Spa-Francorchamps circuit will push the Cadillac team to their limits this weekend as Formula 1 returns to the Belgian Grand Prix.

The Mexican driver called the Ardennes track a ‘completely different challenge’ to any other on the calendar ahead of the 28th race of the season. Spa’s mix of high-speed sweepers, blind crests and the iconic Eau Rouge-Raidillon sequence demands precision and nerve in equal measure.

What makes Spa so special?

Pérez pointed to the circuit’s length and relentless flow as the main hurdles. The track stretches 7.004 km and is packed with full-throttle sections where drivers rarely lift. The Eau Rouge-Raidillon complex alone combines a steep drop into a blind crest followed by a brutal uphill climb, producing negative G-forces that test both car and driver.

“Your heart always beats a bit faster there,” Pérez said. “It’s a very fast circuit and unusual in that you experience negative G-forces when going through the Eau Rouge sequence.”

Why this weekend matters for Pérez and Cadillac

The Mexican’s team has struggled with reliability issues in recent races, particularly with the brakes. Cooler Belgian temperatures could ease that pressure, but the bigger test lies in energy management. Cadillac’s Ferrari-sourced power unit packs more electric assist this season, forcing drivers to balance aggressive deployment with recovery in Spa’s few slow corners.

Pérez added: “It’s going to be interesting in terms of energy management, handling and tyre management. We’ll focus on that on Friday while also analysing the further developments we’ve brought with us.”

Team-mate Bottas echoes the challenge

Valtteri Bottas, Pérez’s team-mate, stressed the need for confidence in the car to attack Spa’s fastest turns. The Finn said the track rewards drivers who trust their machinery through the kerbs and blind exits.

“We’ll have to work hard this weekend to fully realise our potential,” Bottas said. “Spa is often seen as all about speed, but it’s more balanced. The driver really needs to have confidence in the car to go flat out.”

What to watch in Belgium

With new parts arriving for Cadillac and the circuit’s punishing demands, Friday practice will be critical. The team must dial in the energy strategy fast, because once the race starts on Sunday, mistakes in deployment or tyre choice could cost vital positions.

Pérez arrives at Spa with the championship fight still wide open. A strong result in Belgium could keep his hopes alive, while a misstep risks handing rivals crucial momentum.
