Fernando Alonso is sure there is more to come from McLaren after the opening day of practice for the Austrian Grand Prix.
Alonso finished 11th in FP2, one place behind teammate Jenson Button, in a session disrupted by rain. The pecking order is still unclear going in to Saturday and Alonso is convinced the team will be more competitive come qualifying on Saturday.
"There's more to come from us because today was just a test day," Alonso said. "There were new parts to try, some worked in a positive way, others didn't work that well, so when we'll put the best parts in the car on Saturday I think we can be quite competitive. I'm quite happy with the way today went, all in all."
Alonso was running a revised McLaren rear wing on Friday and he says the day was useful for aerodynamic tests, although its data was restricted by the afternoon shower.
"We learned less than on a normal Friday because we had less track time, but it was the same for everyone. But we still did quite a few tests, with new aerodynamic parts on top of the normal tyre testing, so now it will be a matter of analysing all the work we did with both cars and choose the best solutions for tomorrow and Sunday.
"In the end we completed the entire program with the exception of the long run with the ultrasoft tyres, because of the time lost to the rain, so tomorrow morning we'll do a few laps with a heavy fuel load - I'm sure other teams will do the same - to learn a bit more."
