Jarno Trulli says he is looking forward to making his return to the Team Lotus for the Hungarian Grand Prix this weekend.

The Italian sat out the German Grand Prix last weekend to allow test and reserve driver Karun Chandhok to make his debut for the team, with Trulli now returning for the final race before F1's summer break.

With Lotus introducing a new power steering system this weekend, Trulli will hope to avoid a repeat of the issues that have plagued his campaign and the former Renault and Toyota man said he was looking forward to getting back behind the wheel.

"I'm obviously pleased to be back in the car and looking forward to getting on track in Hungary," he said. "The Hungarian Grand Prix is held on one of the typical modern Formula 1 circuits - it's pretty stop / start and has a lot of low speed corners with nothing really quick. It's very bumpy and hilly, and it's always very hot, so it's a big challenge for the cars and the drivers but I do enjoy the race there as it pushes the drivers physically, and getting a good lap requires concentration and focus.

"This year it's more difficult than any other season to predict how competitive we are going to be at any of the circuits we race at, mainly because there are so many new factors to take into account that comparisons with previous seasons are largely redundant. However, I think we can expect to be OK because we were competitive in Monaco, a circuit that's pretty similar to Hungary - relatively low speed with a need for good traction to push out of the slower corners and not so much reliance on aero performance."

Team principal Tony Fernandes said he was hopeful that the revisions to the steering system would allow Trulli to take a step forward in performance.

"Jarno will be back and it will be his first chance to try the new power steering system we have developed and tested over the last couple of months," he said. "We are not expecting miracles from that - it is obviously a small part but, for Jarno, pretty vital as the aim is to give him the feel he needs from the car to extract every ounce of performance he can. It will be good to see him back in the pack and I am sure he will be pushing harder than ever alongside Heikki on a track that rewards the best drivers out there."
