Hockenheim, Germany - Sebastian Vettel was fastest for Ferrari in opening practice for his home German Grand Prix on Friday with team-mate Charles Leclerc completing a one-two at the top of the timesheets.
The four times world champion lapped the 4.5km Hockenheim track, located just a half hour’s drive from his boyhood home in Heppenheim, in one minute 14.013 seconds on a sweltering morning.
The German, who crashed out while leading last year's race and is in danger of being upstaged by the younger Leclerc, was 0.255 faster than the Monegasque.
Championship leader Lewis Hamilton, his Mercedes painted in a special livery to celebrate 125 years of motorsport involvement for the German marque, was third and 0.302 seconds off Vettel’s pace.
The Briton, who leads team-mate Valtteri Bottas by 39 points and has won seven of 10 races so far, has expressed concern that the European heatwave could sap his bid for victory on Sunday.
