The defending Formula One champion from Germany, seeking his first win at home, posted a time of 1 minute, 30.916 seconds around the 5.1—kilometer (3.2—mile) Nuerburgring circuit, under dark clouds.
The latest weather forecast predicts an 84 percent chance of rain for the start of the 60—lap race on Sunday.
