Lewis Hamilton called for more changes to his new Ferrari SF-25 after the car’s shakedown at Fiorano earlier this week, it has been claimed. And the fixes are expected to arrive in time for the start of pre-season testing in Bahrain next Wednesday (February 26).

Lewis Hamilton says Ferrari’s F1 car is “completely different” to the Mercedes and McLarens he has driven in the past. The seven-time world champion is gearing up for his first season with Ferrari after completing a blockbuster transfer from F1 rivals Mercedes.

With F1’s current regulations now in their fourth year, the performance gaps that gave front-runners comfortable advantages are shrinking fast. Teams that were once struggling to keep pace have had enough time with these cars to catch up on the learning curve. (See: Ferrari and McLaren’s surge last year .)
