Nasr urges caution over Sauber's major upgrade

Felipe Nasr says Sauber's major aerodynamic upgrade at the Singapore Grand Prix may take a few races to show its full potential.

Sauber has introduced limited new parts to its car so far this season, but has scored in each of the last three races thanks in part to a power unit upgrade in Belgium. The team has been working on a new aerodynamic package to introduce in Singapore and Nasr says it is an exciting step but warns it may take time to get on top of.

"It's difficult to predict how much of an effect it will have but it's something to look forward to," Nasr said. "I'm really looking forward to it, I've been waiting so long for this update. The team as well has put in a lot of effort in to this. It's not an easy track, Singapore, so to validate all the numbers will be important on Friday and we'll take it from there.

"Sometimes you need time for the upgrades to work properly. After Singapore we have Suzuka, a track where you really need the car to be working well on the aero side. So that will be another decent step for us to validate all these numbers."

With Sauber introducing a front wing earlier this season which did not work as expected, Nasr is hopeful there will not be a repeat next weekend.

"There was a lot of work done on that so I'm confident we should be in the right direction. As I said, we cannot predict what is going to happen, we have to validate the numbers. As we did in China we validated the numbers, we saw they didn't correspond with what we expected and we have to do the same in Singapore. Then we'll see if it's better or not."
