Nico Hulkenberg said he was happy to score points for a second successive race at the Canadian Grand Prix, but held ambitions of challenging for the top six places.
Hulkenberg started from ninth place at the Circuit Gilles Villeneuve and ran a two-stop strategy to move into eighth position, earning four championship points.
However, Hulkenberg believes the VJM09 was more difficult to drive in race trim compared to its form across a single lap in qualifying.
"I’m happy to score points, but at the same time I was hoping for a bit more from the race because I really believed we could challenge the top six," he explained.
"For some reason the car didn’t feel as good in the race as it did during practice and qualifying.
"Maybe it’s because the conditions were so cold and windy, which meant we lost the sweet spot and the car was not easy to drive.
"That’s something we need to look at in more detail and understand."
Hulkenberg's result enabled him to draw level with Carlos Sainz Jr. in 13th place in the championship.
