Mercedes has completed the maiden shakedown of its 2015 car during a promotional event at Silverstone.
The world champions debuted the W06 Hybrid at the Northamptonshire circuit on Thursday, with both Nico Rosberg and Lewis Hamilton completing 18 laps between them before the icy conditions brought running to a halt.
The W06 will officially be unveiled in the Jerez pitlane on Sunday, ahead of the start of the first pre-season test.
Rosberg will drive the car on the opening day, before handing over to reigning champion Hamilton on Monday.
The German will be back in the car for the third day of running, with Hamilton driving on the final day of the test on Wednesday.
The Mercedes is the second 2015 car to run on circuit, after Toro Rosso debuted its STR10 at Misano on Wednesday.
