Ferrari reserve driver Antonio Giovinazzi says the squad’s SF71H has improved “dramatically” since his most recent outing in the car in Spain.
Giovinazzi piloted Ferrari’s SF71H at the post-race Barcelona test in May and returned to the cockpit for Tuesday’s in-season running at the Hungaroring.
Giovinazzi set an unofficial track record of 1:15.648 at the Hungarian venue as he used Pirelli’s Hypersoft tyres – that were not available at last weekend’s Grand Prix – to good effect.
“I had tried the car in the Barcelona test rookie, and I must say it has improved dramatically,” said Giovinazzi.
“It’s a big step, last time was in May and now we’re in the end of July.
“It was a big step, it’s really good to see this improvement from the car. It showed the team and drivers are doing a fantastic job to improve the car.
“My main programme, we did a few long runs in the morning and a quali run in the afternoon.
“The rain was coming and we delayed the end of the programme with a lot of long runs.
“It was a good day, positive for me and for the team and this is really important.”
When asked whether the test day was another chance to prove himself for 2019, Giovinazzi responded: “The goal was to do well and try to confirm that you are up to the task.
“But I do not feel under pressure, it has been a positive test and I'm satisfied.”
Giovinazzi will pilot Sauber’s C37 on the second and final day of in-season running at the Hungaroring, having carried out FP1 sessions for the team across the past two Grands Prix.
