Aerodynamics – formerly winglets, now “aero fairings”; specificity important – are another key component that teams must make a final decision on during the Qatar Test. This year it’s a simple choice of two fairings for the year, one of which must be decided upon before the season begins, the other mid-way through, and neither of which can be changed once homologated. And this time around, they also have to fit in a specially designed homologation unit that judges the legality of the fairing – if it doesn’t fit, it doesn’t race. At Sepang, Danilo Petrucci (Mission Winnow Ducati Team) and Jack Miller (Alma Pramac Racing) crashed on their different aero fairings they were trying so they’ll want to get a little more track time under their belts in Qatar before decisions are made, and past Ducati, traditionally the masters of aero innovation, we saw plenty of different options up and down pitlane. “There are always positives and negatives,” said Viñales of aero, and the Qatar Test is the last chance for teams to decide which positives outweigh which negatives.
