Sauber has beat its rivals to the race track, running its new C36-Ferrari in Barcelona during a shake-down at the Spanish venue.
The Hinwill-base outfit posted a short video of the run, with Sauber's Marcus Ericsson doing the duties.
Team mate Pascal Wehrlein will still be in recovery mode next week when pre-season testing kicks off at the Circuit de Catalunya as a result of a back injury sustained at last month's Race of Champions in Miami.
