Quartararo's final improvement came with just over an hour to go, with his 1m55.616s ensuring he would his 78-lap test programme on top.
Vinales – who only briefly tried the prototype 2020 engine Yamaha brought to the test – threatened Quartararo late on but came up just short with his 1m55.628s.
Teammate Valentino Rossi did run the new engine, and a late surge moved him up to his race finishing position of sixth.
Franco Morbidelli on the sister SRT M1 made sure all four Yamahas would occupy positions inside the top six after going third quickest with a 1m55.755s in the closing stages.

He headed Marquez by 0.073s, the Honda rider trying a new aerodynamic fairing which he may homologate and race this week in Austria.
