F1 in Miami: That's what it looks like when an upgrade works

Formula 1 returned in Miami after a five-week break, with teams arriving with major upgrade packages.

McLaren’s development process is translating well from simulation to track, helping it close the gap to the front.

Ferrari and Red Bull also made gains, while Mercedes’ early-season edge has faded.

The result is a tighter, more unpredictable championship fight that now looks like a four-way battle.
