Sauber driver Sergio Perez has conceded that the Swiss-based outfit will have its work cut out in the final four races, if it is to score enough points to haul in Mercedes and secure fifth place in the Constructors' championship.
Perez was frustrated not to be able to add to his tally in Korea last weekend and felt sixth would have been possible had he had a clean run.
However he is optimistic that the Ferrari-powered C31 will go better at India's Buddh International Circuit, and as well as looking to add to the team's 116-point score, he will also want to add to his own.
“I cannot believe we have only four races left, so the season will now end quite soon. To make up 20 points to finish fifth in the Constructors' World Championship means we have quite a job to do. But the race in India should be a bit better for us than in Korea, and our car will be quicker there,” he said.
“I like the fluent sections of the track [in India]. Outside the circuit I haven't seen anything of the country yet and I know that, unfortunately, I won't have time for a trip this year either,” he added.
Sauber team principal, Monisha Kaltenborn, meanwhile will be in demand as it is her home event and and she has called on the squad to make sure it 'maximises' its potential.
“For me the second F1 Grand Prix of India certainly will be a very special race. Going to my home country, not for private but for business reasons, and for the team to race in front of my fellow countrymen is exciting. This is the emotional part of it,” she continued.
“Looking at it in a more sporting way though, it is clear we want to score a lot of points, be it in India or at any of the remaining four races.
"Technically the track in Greater Noida should not be a problem for the C31, but it isn't our favourite either. We have to stay focussed and maximise our potential there.”
