Daniil Kvyat says he'll be better prepared for 'one of the most challenging races' on the Formula 1 calendar after a gruelling debut experience in Singapore last year.

The Russian driver endured an energy-sapping maiden Singapore F1 Grand Prix in 2014 while driving for Toro Rosso after his drinks mechanism failed during the race and had to suffer through the extreme heat.

On average drivers can lose up to three kilograms in weight during a race at the sticky street circuit and Kvyat says his performance was seriously hampered by not being able to take on fluids.

"It's definitely one of the most challenging races of the championship," Kvyat said. "It's the longest, one of the hottest and one of the most physically demanding races we face. Having said that I do like the track because although it's a street circuit, it's quite a bit quicker than Monaco. As GPs go, it tends to have more atmosphere than the average."

"Last year it was extremely tough because my water bottle didn't work, so it was a very difficult race. But this year I think I'm much better prepared from a physical point of view, so it should be fine. For example, Malaysia this year felt a lot more comfortable than last year and it's similar, so I think I will be OK."

Despite Red Bull's ongoing troubles with power unit supplier Renault the Singapore street circuit is expected to suit the RB11, with the team grabbing a double rostrum result in 2014.

Kvyat is also on a strong run of form having notched up four consecutive points finishes, with the standout highlight his maiden Formula 1 podium in Hungary, and the 21-year-old has been making serious inroads in the drivers' championship standings.

Kvyat currently sits seventh in the F1 championship and heads the pack chasing the dominant Mercedes, Ferrari and Williams drivers.
