London: Formula One world champion Lewis Hamilton and team mate Nico Rosberg gave their 2015 Mercedes race car a `shakedown` test at Silverstone on Thursday before a snowstorm forced an end to proceedings.
Mercedes said the F1 W06 hybrid car, due to be formally unveiled at the first pre-season test in Jerez on Sunday, took to the track in icy conditions for a limited mileage promotional event.
"Driven first by Nico Rosberg, then Lewis Hamilton, the car completed a total of 18 laps (47.2 km) before a blizzard brought filming to a halt," the team said in a statement.
Mercedes won both championships last year, with Hamilton taking 11 victories to Rosberg`s five.
The team are expected to set the pace again this season, with Britain`s Hamilton chasing his third title, although rival engine makers Renault, Ferrari and Honda hope the performance gap will have narrowed.
The season starts in Australia on March 15.
