• The weather. Rain and early morning fog is possible both at Monza and in the mountains, while ice cannot be ruled out at Friday and Saturday’s higher altitudes.
  • Road conditions in the mountains will deteriorate with the passage of each car. Mud and leaves will be pulled onto the surface as drivers cut corners to save vital tenths.  
  • Driving in the dark. Friday’s Grand Prix and Saturday’s closing Sottozero tests are contested in darkness.
  • The Cinturato, Roggia and Serraglio tests at Monza include several sections of tricky gravel, which will become increasingly muddy and slippery.
  • Sunday’s Serraglio is a real rhythm-breaker. There are 22 surface changes in less than 15km.  


Car spec

  • Asphalt set-up. Pirelli’s P Zero hard compound tyres will be the primary option for top-tier competitors, with a soft compound version also available. Extreme wet weather could bring the Cinturato rain tyre into play, while a repeat of last year’s snow and ice will see crews calling on the Italian company’s Sottozero winter rubber.
