Red Bull has work to do before Miami. Verstappen finished eighth — seven places behind his teammate Hadjar, who took twelfth. The car wasn't just slow through Sector Two. It was losing time everywhere except the straights.
Mercedes, meanwhile, found something in Japan. Antonelli led 32 laps and controlled the race after taking it from George Russell on Lap 21. Russell finished fourth.
If the W18 has this kind of edge through technical sections, Miami's going to be uncomfortable viewing for Milton Keynes.
