Valtteri Bottas completed the first laps of a Formula One car since preseason testing in a Mercedes test at Silverstone on Tuesday.
In the first of two days allocated to the reigning world champions, Bottas took the team's 2018 title-winning car (decked out in the 2020 livery) around the circuit set to host two races in August -- the British Grand Prix on August 2 and the 70th Anniversary Grand Prix on August 9.
F1's regulations allow two days of running an old-spec car at private tests, limited to 100km of running each and usually reserved for filming and sponsorship .
