Paul di Resta endured a mixed day during practice for the Canadian Grand Prix.
The Brit was fastest in a damp first session but was only thirteenth in the afternoon session, which was cut short when his Force India VJM06 developed an electrical issue.
"We were quite cautious with the wet weather this morning and we only fitted the dry tyres for the last few minutes of the session," he said of his run during the first session. "Before that I had a good run on the intermediates and felt happy with the performance – probably the most comfortable I’ve felt on the intermediates this year. So overall we didn’t look too bad in the damp conditions."
"The afternoon was a case of getting through the dry tyre programme and trying to find the right car balance. Unfortunately things were cut short with the electrical issue, so I didn’t do the long runs we had planned for the final part of the session."
Adrian Sutil believes Force India has a good car for their 100th race this weekend.
"We had lots of different track conditions today, but the car was quick in both sessions. In the dry this afternoon the main issue was warming up the front tyres, especially the medium tyres. On the supersofts there was much better grip and the long runs seemed quite competitive so it feels as though we are at our usual level here. Tonight we just need to work on making the car more consistent," he said.
