Alpine's Fernando Alonso capped off Pirelli's three-day test in Bahrain during which F1's supplier continued the development of its 2022 18-inch tyres.
Ferrari's Charles Leclerc and Carlos Sainz were in action on Tuesday, the pair completing 141 laps at Sakhir onboard the Scuderia's mule car before Alpine took over testing duties on Wednesday and Thursday.
Esteban Ocon notched up a trouble-free 100 laps for Pirelli while Alonso racked up a massive 144 for the tyre manufacturer on Thursday.
"It was a great day of testing at the Bahrain International Circuit and the new tyres feel good already," said the Alpine charger. "It is at an encouraging stage of development.
"Hopefully with all the laps we did today we can help Pirelli develop and help understand the tyres even better.
"It was a well-executed day by the team and Pirelli with some useful information."
Save for Williams which does not have the ability to field a mule car for Pirelli, the remaining six F1 teams will all have the opportunity in the coming months to sample the tyre manufacturer's 2022-spec product.
Pirelli's next 18-inch tyre test is scheduled to take place at Imola on April 20-21 with the Mercedes team.
