Sauber team principal Monisha Kaltenborn insists that the Swiss team hasn't given up hope of taking fifth in the constructors championship from Mercedes despite failing to score in the USA.
Mercedes' failure to pick up any points for the fifth successive race gave Sauber the chance to bring down the twelve point gap between the pair but Sergio Perez and Kamui Kobayashi were both unable to bring home a top ten result.
Perez had the stronger run of the pair in the race but braking issues meant be could only take the flag in eleventh spot.
“My start worked really well and the first laps were good too,” he said. “I had a good pace, and the car was really quick, but then around lap ten I had a problem with the brakes. The pedal became very long and I had big difficulties before every corner. This cost a lot of time and so we didn't manage to get any points here.
“Regardless of the result it was a great experience to race here in front of so many Mexicans. The COTA is a great track and I hope we can have this Grand Prix on the calendar for many years. Now we will get ourselves together for the final attempt to improve to fifth place in the Constructors' World Championship next week.“
With Kobayashi down in 14th having struggled with tyre temperatures all weekend, the team was left to wonder what might have been, although Kaltenborn said Sauber wasn't giving up as it looks to beat Mercedes in the title race.
“For our team it was a weekend with ups and downs, which was also reflected in the race,” she said. “Sergio made a very good start and was eleventh after lap one, with a chance to fight for points, but later he reported a brake problem and, as a result, lost positions. Kamui was never able to recover from his grid position.
“We have not given up the fight for P5 in the constructors' championship, but we will have a lot of pressure in Interlagos. However, we are taking this as an extra motivation. Congratulations to the people responsible at the COTA for building a great track and organising a great event for the many fans who were present today.”
