They are coming off two extremely difficult race weekends, but McLaren are confident their MP4-30 package will be better suited to the Marina Bay Street Circuit.
Having claimed a double points finish at the Hungarian GP, the Woking-based squad slipped backwards at the high-speed Spa and Monza circuits as they left those venues empty handed and with plenty of grid penalties.
However, McLaren always knew they were going to struggle at those venues, but the high-downforce Singapore track should give them a better chance of being higher up the grid.
"There's always a lot of anticipation in the build-up to this race, and for us it's no different," Jenson Button said. "We've had a couple of really challenging races, but we've said for a while that some of the circuits we go to towards the end of the season should be a bit better-suited to the stronger elements of our package.
"There's no denying it'll be hard work, and we aren't expecting miracles overnight. But, Singapore is a fantastic circuit, it's one of the longest races of the season in terms of time, and we quite often we see a Safety Car there.
"So, anything can happen; we're hoping to learn a lot about how our car works in this configuration, and take as many positives from the weekend as we can."
Although McLaren racing director Eric Boullier is refusing to make any predictions, he is confident they will put on a good show.
"There is no denying that Spa and Monza were incredibly tough races for McLaren-Honda," he said. "We expected it, and it was no surprise when the results came, but it doesn't make it any easier to bear. Saying that, we are entering a phase of the season where the circuits rely less on pure power and more on balance, characteristics that tend to suit our package better.
"Together, McLaren and Honda are constantly striving to improve our package and we have faith in our collective abilities to analyse our weaker areas and continue pushing forward.
"We won't make any promises or predictions, but we love this circuit and hope to put on the best show possible under the incredible floodlights of Singapore. It is truly a spectacular location to host a grand prix and fully deserves its status as one of the flagship races on the Formula 1 calendar."
