Sebastian Vettel of Ferrari went past Lewis Hamilton of Mercedes in a straight fight as Formula 1's new era started at the Australian Grand Prix.
Vettel's first win since the Singapore GP in September 2015 cut down Mercedes' domination after the introduction of faster cars.
Hamilton started in pole but Vettel had an advantage on pace and tyre wear.
The German pressured Mercedes into an early pit stop and benefited when Hamilton was held up by Max Verstappen.
Ferrari were simply quicker in Melbourne and the world champions were forced into a position where they had to make a decision that did not work out.
Mercedes were telling Hamilton he needed to up his pace to build a gap before his pit stop. The Briton was complaining his tyres were going off and he had no more pace.
Mercedes had the choice of leaving him out and risking Vettel passing him by and stopping earlier, or bringing him in and hoping Red Bull's Verstappen would stop soon afterwards or that Hamilton could pass him.
Mercedes accepted that the Ferrari was simply a faster race car on Sunday - something that was clear from Vettel's ability to stick close to Hamilton in the opening laps despite the turbulent air from the Mercedes
