Lewis Hamilton Is Pacesetter in Practice for Japanese Grand Prix

The teammate nearest to Hamilton is Valtteri Bottas, who managed to beat Hamilton's morning times in the afternoon, but remains more than four-tenths down. Sebastian Vettel of Scuderia Ferrari led the other frontrunners by almost another four-tenths down on Bottas in the second session. This was a major improvement in Vettel’s morning times, which were slower than that of his subordinate Kimi Räikkönen.

Speed trap data suggested Vettel may have experimented with a low-drag setup for the first session, as his top speed reached 302.1 kph (187.7 mph) versus Räikkönen's 298.5 kph (185.5 mph), despite posting slower lap times. Adoption of a setup closer to Räikkönen's brought Vettel ahead by more than four-tenths. The drivers for both Ferrari and Red Bull Racing were staggered in FP2 standings with Max Verstappen between the two red cars, and Daniel Ricciardo behind, his pace slipping between sessions instead of improving.

Representation of the midfield teams in the top ten was limited to four drivers, each from different teams. Force India's Esteban Ocon was down more than a half second on Räikkönen, but enjoyed a healthy four-tenths gap to Haas's Romain Grosjean. Less than a tenth separates Grosjean from Alfa Romeo Sauber's Marcus Ericsson and Scuderia Toro Rosso-Honda's Brendon Hartley. Hartley appeared to be another setup experimenter, scoring sixth-fastest in the FP1 speed trap at 299.4 kph (186 mph), but his lap times were down with the Williams’ and McLaren’s teams. Changes to his FP2 program saw him cut more than 1.4 seconds and slip into the top ten—important for Honda at its home race.
