Mercedes completed 100km of running on Friday during a shake-down of its 2017 car at the Silverstone circuit.
Nico Rosberg kicked off the day before handing the car over to current world champion Lewis Hamilton, who will be hoping to defend his title with the W07.
The car won't make an appearance again until the opening pre-season test which begins on Monday. Hamilton will be behind the wheel on day one, before handing the car over to Rosberg on the second day.
