Valtteri Bottas produced a stunning track-record lap to deny Lewis Hamilton pole position at the season-ending Abu Dhabi Grand Prix.
Mercedes driver Hamilton, who was aiming to level his personal-best tally of 12 poles in a single season, had dominated FP3 earlier on Saturday at the Yas Marina Circuit.
And when the Briton went quickest after Q2 it look like as though he was course to top the timesheets.
However, in a qualifying session that regularly saw the track record broken it was Bottas – who still has a slim chance of finishing second in the standings with victory on Sunday – that took top billing with a time of one minute and 36.231seconds.
Bottas consequently secures back-to-back F1 poles for the first time in his career, and Hamilton – who wrapped up a fourth world title in Mexico last month – will have to pass his team-mate to end the year with a victory.
