Vettel is set to start his home race last after failing to set a timed lap in Q1, while Leclerc looked a hit favourite for pole until he was forced to abandon his efforts at the start of Q3, taking 10th on the grid as a result.
Mercedes had been on the back foot for much of the weekend, with Ferrari take one and two in all of the practice sessions, prompting a change of bodywork on Hamilton's car as they desperately sought more pace.
In the end, things fell into the Silver Arrows' lap as the Scuderia dropped like flies and Max Verstappen's Red Bull was just unable to match pace with Hamilton.
The Dutchman took second, with Valtteri Bottas third, but the heavy threat of rain for Sunday's race ensures thrills and spills remain guaranteed.
Ferrari should move their entire operation to the UK.
