Rookie Esteban Gutierrez will head to the first race of the 2013 season with more pre-season mileage under his belt than any of his 21 rivals.
Gutierrez, along with team-mate Nico Hulkenberg, also ensured that the Sauber C32 will head to Melbourne as the car with the most running during three pre-season tests in Spain.
Sauber completed 5307 kilometres across the three tests, slightly more running than Mercedes, who bounced back from a shaky start in Jerez.
At the end of the spectrum was Davide Valsecchi, whose 16 laps in place of Kimi Raikkonen during the final pre-season test equated to 74 kilometres around the Circuit de Catalunya. Out of the regular race drivers, Adrian Sutil completed the least running.
