Adrian Sutil says he can't wait for the F1 season to resume at Spa this weekend on a circuit that 'always puts a smile on a driver face'.

The German heads to Belgium keen to return to the kind of form that saw him take sixth place in his home race after a tough weekend in Hungary prior to the summer shutdown saw him trail in down in 14th.

Sutil scored his best result of the year at Spa twelve months ago when he finished fifth and he insisted he couldn't wait to return to the famous Ardennes circuit to get the second half of the campaign underway.

"I always say that Spa is my favourite circuit of the year," he said. "I just love the place. There's nowhere else like it and the range of corners feel so impressive in a Formula 1 car. I think all the drivers have a big smile on their face when they come back to Spa. I think we can have another competitive weekend because the last couple of races have shown what we are capable of. We seem to have a car that is working well everywhere and our qualifying and race pace has been strong. We just need to keep up the momentum and keep picking up the points.

"When you come to Spa you always have to keep an eye on the weather. For the last three races it feels like the rain has been following us and we should probably expect some more rain showers this weekend."

Team-mate Paul di Resta will be returning to Spa for the first time since his F3 days and the Scot insisted he too couldn't wait for the weekend.

"The result in Hungary was the best way to end the first part of the season," he said. "There have been a few races where things didn't go our way so it felt good to get the result we felt we deserved. It helped make up for some of the bad luck we've had over the last couple of months. Spa is a track that has historically been strong for us. And our recent form gives us every reason to believe we can carry on where we left off in Hungary.

"We know our competitors won't have stood still, but we're still pushing hard with development and determined to get as much performance from the car before the focus shifts to next year. Spa is not a track that I've raced at much before. I drove there in Formula 3 seven years ago, but I think it will be a completely different experience in a Formula 1 car. It's one of the best tracks in the world and I'm excited to be going back there."
