Pierre Gasly believes he has found the strengths and weaknesses of his new Alpine after just one session of pre-season testing.
The Frenchman made the switch from AlphaTauri over the winter to replace new Aston Martin recruit Fernando Alonso.
With F1's Bahrain pre-season test beginning on Thursday [February 23] for the first of three days, Gasly was given the honour of driving the A523 first, finishing ninth quickest with 60 laps under his belt.
"Obviously everyone is excited wanting to know how the car was - in 60 laps in these conditions, it is all sort of relevant to others and engine mode and fuel etcetera.
"Based on my feeling, I felt comfortable, I could spot strengths and weakness straight away, what sort of direction I want to take in terms of car balance so it was very productive.
