Mercedes boss Toto Wolff is curious to know whether his team has fixed the problems it suffered at the Singapore street circuit last year.
Singapore proved to be an anomaly in an otherwise dominant season for Mercedes in 2015, with Lewis Hamilton qualifying 1.4s off pole position in sixth and Nico Rosberg (the only Mercedes finisher) crossing the line 24s behind race winner Sebastian Vettel. The team addressed the car's set-up at the following rounds of 2015, but Wolff says the only way to know if the problems are solved for sure is to return to the track this weekend.
"We weren't competitive there last year and I think we understood why," he said. "We made some conclusions that helped us in the following races and throughout the season, and in Singapore [this year] we are going to check if we were right.
"There is no silver bullet or one thing that went wrong, but many things probably related to each other. This is why I'm really curious and excited to see how Singapore is going to work."
Wolff said Mercedes aims to have a car that is as good as possible at as many races as possible during the season, but admitted there are always going to be weaker tracks.
"You can see where we got it right is that our car is the best compromise over 21 races and you need to have a chassis, engine and aero combination that works well on average. And then you have outliers and there are teams that are doing extremely well on circuits like Singapore because they are high downforce, but they are not competitive on a circuit like Monza."
Wolff went on to draw a comparison with Red Bull, which struggled at Monza this year.
"You can play the blame game and say the engine is not good enough, the car is draggy and has a rake like you are doing a handstand - but then you can't expect it to go fast on the straights. It's about finding the best compromise, so let's see what happens in Singapore."
