Qualifying in MotoGP is always important, but at the Termas de Rio Hondo track in Argentina, it matters just that little bit more. That would seem odd at such a fast and flowing track, but the problem is that the circuit doesn't get used much. That leaves the surface dusty, and without much rubber on the track to provide grip. Over the three days of the Grand Prix weekend, the three classes gradually clean up the track and put down a layer of rubber, adding to the grip.
The trouble is, because it is practice and qualifying, most of that rubber gets laid down on the racing line, as everyone tries to find the quickest line around the circuit. Stray from that line, and you are quickly back in green, dusty tarmac, with nary a hint of rubber on it. The grip is gone. "That's an important thing, because if you go 1 meter wide, you feel the bike like it is floating," is how Danilo Petrucci describes it.
That's why qualifying matters so much. If you start from the first couple of rows, you stand a chance of getting in the leading group, and biding your time until a safe opportunity presents itself. But if you don't qualify up front, or you mess up the start, then you have to take your chances out on the dirty part of the track, and hope your luck holds.
Run wide at your peril
