Lotus Renault GP team boss Eric Boullier has said 'his' team has already put Singapore behind them.

The Enstone-based approach was way off the pace around the Marina Bay Street Circuit, with Bruno Senna and Vitaly Petrov eventually finishing in 15th and 17th respectively - and somewhat alarmingly split by the Team Lotus car of Heikki Kovalainen.

Despite that disastrous weekend though, Boullier believes the Japanese Grand Prix will be better as it is a much faster track - and he also added that next year's car definitely won't be so feeble in the slow stuff.

"Yes [Singapore is a painful memory], but to be honest we've all put this experience behind us," Boullier noted ahead of the 15th round in the F1 2011 World Championship. "We fully understand why we performed so poorly and the explanation is simple: slow corners in the 60-100km/h range just don't do it for the R31. It is written in its DNA.

"We could have worked three weeks on the set-up but we would not have found a second in laptime.

"This is what we know, and our mid-term mission is to make sure that we solve this issue with the R32 which should not be a problem.

"Things should get better for us on quicker tracks and Suzuka is one of them. In Japan, we expect to return to the level of performance we saw in Belgium and Italy. Our mission will be to focus on getting both cars into Q3. From then on, the weekend should be pretty straightforward."

Technical boss James Allison meanwhile also reckons that the Japanese Grand Prix will be more fruitful.

"I expect us to be much more in the hunt than we were in Singapore," he continued. "There are just two slow corners at Suzuka, and the R31 is much more at home on flowing, faster tracks.

"I will be disappointed if we are not in the top 10 cars in qualifying to give us an opportunity to exorcise the disappointment of Singapore.

"We ought to be able to get the car back into the points. We need to - Force India F1 is starting to breathe down our neck and we need a few good results to stay ahead," he concluded.
