The Briton, stung by Sebastian Vettel in Melbourne two weeks ago, pipped his German rival by two tenths of a second in Shanghai with Mercedes team-mate Valtteri Bottas and Ferrari’s Kimi Raikkonen filling row two for Sunday’s race.
Hamilton jumped onto the pit wall to soak in the adulation of the crowd after clocking the fastest lap of one minute, 31.678 seconds to capture his fourth Chinese pole in five years.
“We knew it was going to be close,” said Hamilton, forced to play second fiddle to Vettel in the third practice session earlier in the day.
“I managed to just chip away at it from session to session. It’s exciting for me because we really fight with these guys,” added Hamilton, a four-time winner in Shanghai.
“That’s what racing is all about. It really pushes you to raise the bar each time you go out there.”
Vettel, meanwhile, was left shaking his head in disbelief.
“I don’t believe that, it was the perfect lap,” said the four-time world champion, who looked unstoppable in Saturday’s practice run.
“I think we can still improve, so let’s see what the race looks like tomorrow. Conditions will be different.”
