Lewis Hamilton edged team mate Nico Rosberg by 0.024 seconds as hot conditions pushed track temperatures up to a blistering 58C.
Drivers were repeatedly warned to cool their cars during the 90 minute session. Brakes were a particular concern – Rosberg’s smoking heavily after he pulled up behind Hamilton in the pits at one point.
Both Caterhams suffered technical problems during the session. Marcus Ericsson came to a stop early on and Kamui Kobayashi had a small fire at the rear of his car which required attention from the marshals.
The two Red Bull drivers were urged to cool the left-hand side of their cars through Hockenheim’s fast right-hand turns. But Daniel Ricciardo was able to lap within a tenth of a second of the Mercedes drivers.
Kimi Raikkonen was fourth-quickest for Ferrari followed by a trio of Mercedes-powered cars: Felipe Massa sandwiched by the two McLarens.
