Alpine completed just 12 laps on the final day of pre-season testing in Barcelona following a fire at the rear of their car.
Alonso caused the first red flag of the day when he came to a halt on track with smoke pouring from his car. The car was swiftly recovered, but the Spaniard didn’t return to the track, with the team confirming it would be unable to complete the necessary repairs in time.
A “minor sealing issue” meant hydraulic fluid was ignited, causing damage to the rear of the A522.
“After further investigations in the garage following Fernando Alonso’s on-track stoppage earlier this morning, the team can confirm the issue was a problem with the hydraulics. A minor sealing issue led to a fire in the back of the car.
“The team has successfully completed 266 laps during the three days of the Barcelona shakedown. Repairs on the car will continue, and as a result we won’t be running for the remainder of the day. We look forward to be back in action at the next test in Bahrain.”
Alonso completed just 12 laps on Friday and had been due to hand the car over to team-mate Esteban Ocon for the afternoon.
The morning session saw five red flags in total. Alfa Romeo’s Guanyu Zhou causing two after spinning twice, whilst Pierre Gasly and Sebastian Vettel both stopped on track with issues.
