Adrian Sutil led in Australia before finishing in seventh place, narrowly ahead of the sister car of Paul di Resta.
"We have scored points in Sepang the last three times we raced there, including a double-points finish last year, and I believe we can build on the early-season momentum to bring home a valuable result," he said.
"Last weekend’s race in Melbourne was a great demonstration of how far the team has come lately: to race against the established front-runners on merit shows the quality of our car, of our driver line-up and of the work everyone in the team is producing every day, whether at the factory or at the circuit. We have led the last two races and hopefully soon we will have a special result to repay all that effort", he added. "It is important not to get carried away with enthusiasm: we will need to channel this positive energy into consistently good performances and continue to improve. We are on a good road, and we must all keep progressing."
Paul di Resta believes the team has reasons to be optimistic but is cautious about the unpredictable nature of the event.
"You never know what to expect! It could rain, or it could be dry. Temperatures are going to be high, degradation is going to be high, but I think our car is going to suit the warm weather," he said. "We’ve had a reasonably strong performance for the last couple of years in Malaysia, so I think we should go there feeling quite optimistic. We have a few days to conquer the jet lag and hopefully be fighting fit."
Sutil concurs with his team-mate's view.
"I finished fifth in 2010, so I have some good memories. It’s not my favourite track, but it depends on the car. If the car is quick and stable, you enjoy it more, but sometimes you really struggle with the balance, and then it’s a real challenge – the corners are so long, you need a lot of aerodynamic grip," said the German. "It’s a track I like to drive, but it’s not like a Monaco or a Spa. I don’t really know what effect the high temperatures will have because we haven’t had them during testing. I think the weather in Australia suited us quite well, so let’s see how Malaysia is."
