Formula 1 juniors Charles Leclerc and Alfonso Celis Jr. continued their development by taking part in a two-day Pirelli tire test earlier this week at the Autodromo Hermanos Rodriguez, staying out in Mexico following last weekend’s grand prix.
Leclerc, 20, enjoyed more time with Sauber in the team’s C36 car after taking part in opening practice in Mexico, with the Ferrari’s youngster and Formula 2 champion’s program gearing him up for a race seat with the Swiss team next year.
Leclerc was joined on-track in Mexico by Force India development driver Celis, 21, with the drivers completing 115 and 114 laps respectively on Pirelli’s prototype tires for 2018.
Leclerc had the track to himself on Wednesday, where overnight rain allowed him to sample Pirelli’s intermediate tire before moving onto slicks later in the day, completing 104 laps in total.
Pirelli’s next 2018 tire test will take place at Interlagos following the Brazilian Grand Prix on November 14-15, with McLaren in action.
