What was all the fuss about?
It was unclear what to expect from Sauber at the second test, where they became the final team to launch their 2016 car in a year the pre-season schedule has been reduced from three tests to two.
Memories of Force India's recovery from a slow start to 2015 to secure their best-ever championship position of fifth were still fresh in the mind, yet so too were those of Lotus, who missed the first test of 2014 and spent the rest of the season regretting it.
Any fears that the C35's late introduction would leave Sauber stranded at the rear of the field evaporated as soon as the first day, however, when Felipe Nasr rolled out of the garage and instantly completed 103 laps.
If it seemed too good to be true, it was.
Marcus Ericsson endured a rotten Day 2, completing just seven laps in the morning session due to technical problems before losing his rear-right wheel in the afternoon, leaving the Swede with a tally of 55 laps.
With a maximum of four official testing days until the Australian Grand Prix, Sauber couldn't afford any more days like that and very quickly got back on track, with Nasr setting 116 laps on Day 3 before Ericsson more than made up for his earlier disaster by completing 132 on the final day.
With a total of 406 laps in the second test, Sauber racked up just 24 fewer laps than they did with their tried-and-tested 2015 car at the opening test, proving the gamble of delaying the C35 was worth taking.
Per Sauber's official website, team principal Monisha Kaltenborn claimed the Swiss outfit must re-establish themselves as solid midfield runners in 2016.
And while the team are likely to begin the season in the lower regions of the midfield—quicker than Haas and Manor but just behind Renault and McLaren Honda—Sauber appear to have a good baseline with the C35.
