SPIELBERG, Austria — Formula One world champion Lewis Hamilton posted the fastest time in the first two practice sessions for the season-opening Austrian Grand Prix on Friday.
The British driver twice finished ahead of his Mercedes teammate Valtteri Bottas on the 4.3-kilometer (2.7-mile) Red Bull Ring circuit in Spielberg nestled at the foot of the Styrian mountains in southern Austria.
Bottas was .356 seconds behind Hamilton in the damp and overcast morning run and improved to .197 back as the track dried and became warmer in the afternoon. Late in that session, however, he had to return to the pits because of a braking issue.
Red Bull driver Max Verstappen, who has won the past two races here, was third quickest in the first practice but slipped to eighth in the second session and encountered oversteering problems.
Ferrari struggled for speed in the morning with Charles Leclerc 10th quickest and Sebastian Vettel only 12th, but improved in the afternoon with Vettel pushing up to fourth behind Sergio Perez in third. Perez's Racing Point team uses Mercedes engines.
Although Vettel showed good cornering speed, he was still a somewhat distant .657 seconds adrift of Hamilton's time in the second session.
Ferrari is racing with the same car it used in preseason testing in February and has not made any upgrades, while Mercedes and other teams have.
After making a late strategy decision in terms of aerodynamic development this week, Ferrari is not upgrading its cars until the third race in Hungary, where practice starts on July 17.
Austria is hosting back-to-back races as part of an eight-race European swing, after the season was postponed for four months because of the coronavirus pandemic.
There are no fans allowed at races until further notice.
