Red Bull always expected the Singapore Grand Prix to represent one of its best chances to score a strong result over the rest of this Formula 1 season. The Marina Bay F1 circuit is a street track, so lacks the sort of lengthy straightline sections that expose the power deficit of Red Bull's Renault engine.
That's why the team deliberately incurred so many grid penalties for engine component changes last time out at Monza, to ensure it came to Singapore with the freshest and most reliable combination of power unit elements it could run without incurring further sanction.
The Red Bull has also improved drastically since a major front wing update was introduced for July's British GP. That aerodynamic step dramatically improved the feel of the car for the drivers, and further tweaks over the next three races have helped turn the RB11 into something that Daniel Ricciardo now reckons is basically as decent to drive as last year's race-winning RB10.
