London - Lewis Hamilton is awaiting an email explaining the lack of performance that cost him a shot at winning his fifth world title in Texas on Sunday.
After speaking to his team, the world champion hinted at a mystery glitch behind Mercedes’ slight dip. Sportsmail understands there was, in fact, a set-up problem with his car - it was not put down square - so he was not as fast as expected.
Hamilton finished third behind Ferrari’s winner Kimi Raikkonen and Max Verstappen of Red Bull.
Mercedes has been looking into the set-up concerns, which also impacted team-mate Valtteri Bottas.
Hamilton’s race engineer Peter Bonnington will report back to him in an email before the Formula One circus arrives at the Mexico City track on Thursday.
