Nicolas Prost said he was confident in his own ability after a solid A1GP debut for Team France at Chengdu, despite failing to finish the feature race in China.

Called into the team for the weekend to replace Zandvoort race winner Loic Duval, Prost qualified in sixth place for the sprint race - taking the flag in eight after losing two places early on.

From twelfth on the grid for the feature race, Prost was making solid progress up the order but when he tried to go outside John Martin into turn one mid-way through the race, a lack of grip saw him spin off into retirement.

"Of course, I'm frustrated at not having scored more points this weekend," he said. "This being said, there are a lot of positive elements to be taken from what happened.

"I really didn't know what to expect on arriving in Chengdu, and I was very happy to see that I was able to lap in the times of the front-runners straight away. Our two races were really decided yesterday in qualifying. If things had worked out better we'd have started from the front row, and the result would have been very different.

"By starting from twelfth spot in the Feature event, I had to drive an aggressive race and take risks. It's better to end up in the gravel trap than to come home in an anonymous tenth place!

"I've learned a lot this weekend, and I'm reassured in my ability to get the very best out of the new A1 GP single-seater."
