Until a few months ago, a lot of the F1 statistics and data were split across pages on the main Autosport site and Forix. We decided to consolodate all of them on Forix as it makes sense for them all to be together, though I realise that this has made things a bit more tricky if you were used to knowing where to go to find certain stats...
From the main Grand Prix page (here for the last race in Brazil), select any driver from the participants list on the left hand side. Once you're in that driver's page for the Grand Prix, there will be a link on the left which says, "laptimes". This will take you to a page like this.
From the race page, you can also access the other data that was previously showing in AUTOSPORT+ rather than on Forix, including the detailed gap chart and the ability to see the classifications on every lap of the race.
