Narain Karthikeyan has made matching his HRT teammate Pedro de la Rosa in qualifying his major aim for the second half of the Formula 1 season.
The 35-year-old Indian is yet to outqualify de la Rosa this year and, while he feels his race performances have been strong, he concedes he has to raise his game on Saturdays.
"I think that my race performance has been very strong, with my 15th place in Monaco standing out, but in qualifying I've been a bit weaker," said Karthikeyan. "Right now I'm about three tenths [per lap] behind Pedro and that's something I have to improve in this second half, no doubt about it."
Karthikeyan admitted that he is still trying to adapt to Pirelli's tires, of which de la Rosa has more experience.
"The tires have been quite difficult to get used to and Pedro has a lot of experience with Pirelli and McLaren. He's a very good driver who hardly makes mistakes and I must learn from him to improve," he said.
The HRT driver said that finishing ahead of his team-mate in the championship standings would mean a successful season for him, given the Spanish squad's current form.
"From where we are now, it would be great to match and beat my teammate Pedro, who has been a good benchmark. Added to that, if we finish ahead of Marussia in the championship standings that would be a successful season."
