Montreal: Force India driver Adrian Sutil is relying on the new updates, including the blown diffuser, in his car for a good result in Sunday's Canadian Grand Prix.

Last year both the Force India cars had made it to the Q3 with Vitantonio Liuzzi qualifying fifth on the grid and Sutil on ninth.

The team, though, could earn only three points and Sutil is hoping for a better performance this season at the circuit, which he terms as his favourite.

"We are still trying to improve our upgrade package that we took to Barcelona. It is not easy to make it work, the blown diffuser, at the moment, the way it should be. In Monaco I think we ran it for the first time in the race. We are not sure if it really was a big advantage but I am sure it was a little. But there is still more to come.

"We need now just time on the circuit to understand a lot of things and we also have some other updates on the car, not only the diffuser, especially for this race here. It should be good for us," Sutil said at the pre-race press conference.

Sutil said the team was keen that it improves in qualifying session and is hopeful of doing that, saying that the low downforce circuit here suits them.

"We have a big straight-line speed. It is a very fast car on the straights. This circuit has fast straights and a few slow speed chicanes and hairpins so it is not such an aerodynamic circuit here.

"Last year was a very good performance here and very strong qualifying with both cars. Hopefully it will be a little bit better here as qualifying is our main issue. The race is always a bit better but still we want to be somewhere else in the field," he said.
