WATCH: Vettel and Stroll put Aston Martin's AMR21 through its paces at wet Silverstone

Aston Martin kick-started their return to F1 on Thursday, with Lance Stroll and Sebastian Vettel giving the Mercedes-powered AMR21 an initial shakedown at a wet Silverstone.

The duo completed the maximum 100km allowed under filming day regulations, on Pirelli demo tyres, giving them the chance to get to grips with the new machine ahead of pre-season testing in Bahrain next week.
