Mclaren, Aston Martin and Alfa Romeo have made the most changes to their cars for this weekend's Spanish Grand Prix in Barcelona. McLaren's updates cover the front and rear wings, front and rear corners, front suspension, floor body, diffuser, engine cover, cooling louvres and sidepod inlets. At Aston Martin, a new floor body, fences and edges have been introduced, along with changes to the engine cover, cooling louvres, rear wing, sidepod inlets and Halo. Aston Martin's modifications, particularly in terms of the sidepods and engine cover, have already drawn comparisons to the front-running Red Bull RB18. Meanwhile, Alfa Romeo have brought new front and rear wings, along with changes to the front and rear suspension, floor body, engine cover and cooling louvres.
What about the rest of the F1 field?
Elsewhere, F1 title contenders Ferrari and Red Bull have both brought various parts in what is becoming a fascinating development race. Ferrari have a new floor body, rear corner and rear wing at their disposal, with Red Bull unveiling an updated front wing and floor body. Mercedes will roll out a new front wing endplate, floor edge, floor body and rear corner, as they bid to get on top of their porpoising issues and join the fight at the front. Williams have developed new front and rear wings, and an updated rear corner, Alpine a new front wing endplate, rear wing and rear corner, and AlphaTauri a modified rear wing. Haas, as outlined by team boss Guenther Steiner earlier this week, have not brought any upgrades to their car this weekend.
