Charles Leclerc produced Ferrari's best laptime of the week on the final morning of Formula 1's first pre-season test, with an effort that puts him close to the overall benchmark set by Mercedes.
During a busy morning of track action, as eight cars ran at the same time, Leclerc completed decent mileage, with his best effort being a 1m16.653s.
This is just two tenths of a second slower than Mercedes driver George Russell managed on Thursday to set the fastest time of the week so far.
While testing times are heavily influenced by fuel loads, run programmes and car settings, Leclerc's delivery of a lap that is in the range of Mercedes - which completed its final day of running on Thursday - caps a week where Ferrari has been encouraged by a strong level of reliability.
McLaren's Oscar Piastri was second fastest as he got back to work after being forced to sit out Thursday afternoon because of a fuel system problem. The Australian completed 79 laps and set a best time of 1m17.446s, which is one second slower than Russell's best effort.
Max Verstappen was finally able to get testing again for Red Bull, with the squad having received spare parts from its Milton Keynes base to replace those broken by Isack Hadjar in his sizeable accident on Tuesday.
Despite a small off at Turn 10 in the morning, the four-time F1 world champion was third quickest with a lap of 1m18.285s.
The main interest in the morning surrounded Fernando Alonso as he got his first taste of Adrian Newey's bold AMR26 car.
Aston Martin had no repeat of the early reliability drama that stopped Lance Stroll on Thursday, as Alonso completed a series of short runs - although it was noticeable that he was keeping his speed limited on the main straight.
Even so, Alonso set a best time of 1m20.795s as he completed a total of 49 laps - with the two-time world champion due to stay in the car for the rest of the day.
Ollie Bearman completed the most laps of any driver (105) as he and Haas made up for lost time following two issues on the team's second day of running on Wednesday.
Pierre Gasly (Alpine), Gabriel Bortoleto (Audi), and Valtteri Bottas (Cadillac) were also in action.
