Home favorite Nico Rosberg completed a timely practice double over his championship rival Lewis Hamilton ahead of Sunday's German Grand Prix.
Rosberg trails Hamilton in the title race for the first time this season after watching his Mercedes teammate win five of the last six races.
But the 31-year-old appears to hold a slight advantage over his rival in Hockenheim after topping both practice sessions during Formula One's return to Germany after a one-year absence.
Rosberg was comfortably faster than Hamilton with his best lap of one minute and 15.614 seconds in the afternoon, nearly four tenths of a second faster than his teammate.
Four-time world champion Sebastian Vettel was best of the rest in his Ferrari, more than half-a-second adrift of Rosberg in third.
The Red Bull duo of Max Verstappen and Daniel Ricciardo were fourth and fifth respectively.
Jenson Button was eighth fastest for McLaren while teammate Fernando Alonso was 10th quickest.
