Lewis Hamilton has revealed that Mercedes have not yet decided which aero package to run in Japan, the new one that Valtteri Bottas raced at Sepang or the old that Hamilton used.

Hamilton raced to second place at last weekend’s Malaysian Grand Prix after deciding to revert to Mercedes’ older aerodynamic package.

His team-mate Bottas stuck with the new one and finished down in fifth place, almost a full minute behind race winner Max Verstappen.

But despite the contrast in pace between their two drivers, Hamilton says Mercedes still haven’t made a call on which package to run in Japan.

“It’s not decided at the moment, it’s a constant discussion,” the Brit told Motorsport.com.
