Fernando Alonso has insisted that Aston Martin will not repeat last season's mistakes in their upgrade programme.
The Silverstone-based team took a huge leap forward at the start of last season, with Alonso grabbing three consecutive third place finishes in the opening three rounds and a total of six podiums in the first eight races.
However, Aston Martin took the wrong direction with their development around the halfway point and results began to fade.
"If not, I could not maybe sleep for the last two months! But I think we did a lot of experiments and a lot of changes back and forth in terms of understanding the problems and the direction and the paths that we need to follow this year on the car.
"I think we understood a lot of things, and with this year's car we intend to improve some of those weaknesses that we saw in terms of developing the car last year that we maybe got into the wrong direction a few times, and we understood a little bit too late.
"Hopefully we have that knowledge, those difficulties from last year were lessons that we took on board for the '24 car, and we will see the result.
"I think we had a good step forward this winter, maybe not as big as last year, because last year the baseline was very poor. And this year, the baseline was very strong already last year's, which is understandable."
