Mercedes risks losing touch with the battle for the runners-up position in the 2013 constructors championship, if they suffer a second successive slump following on from the Japanese Grand prix, where Nico Rosberg rescued just two points for the team after Lewis Hamilton's early retirement.

Hamilton's fifth place the previous week in Korea was the best result of either driver in the last two outings, meaning that the team's chief rivals Ferrari have moved away to a ten point lead in second place in the championship standings. More worryingly, Lotus are rapidly approaching from behind thanks to the double podium the team won in Korea followed by both drivers also finishing in the top five again in Japan.

Unfortunately for Mercedes, India isn't historically one of the team's better tracks - they ended up out of the points here in 2012, which could prove disastrous to the squad if it were to happen again this weekend.

"The last three races have shown us that we have a real fight on our hands to secure second place in the constructors championship," admitted director of motorsports Toto Wolff. "[But] we have the performance to achieve our goal if we consistently deliver the full potential of the car. We quickly put the disappointing weekend in Japan behind us and are now fully focused on the final four races of the season."

"The last few races haven't been the best for us so I am hoping for a good weekend," said Rosberg. "We are all determined to finish the season strongly and to continue our challenge for second place in the constructors championship."

It's Lewis Hamilton's first visit to India with the Mercedes team, and he's finished in the points on both previous outings with McLaren giving him reason for optimism of performing strongly again at Buddh International Circuit this weekend.

"I have really enjoyed our two visits to India so far. It's such a vibrant country and the support that we've received from the fans there has been fantastic," he said. "They love sport and the knowledge that some of the fans that I've met have had about F1 has been great to see. I really hope that we can see the country take F1 to heart in the future.

"We're hoping for a strong weekend after a couple of difficult races and I know that everyone has been working really hard to make sure that we can get all of the performance possible from the car over the last four races," he continued. "We know that we have a good car and, if we can put together a good race weekend, then we have the potential for some great results before the season is over."

"I also really like the Buddh International Circuit. The layout has a great rhythm and I love the fast turns and high speeds," Hamilton added.

Team principal Ross Brawn agreed that Buddh was "a good challenge" for both drivers and engineers, with its combination of low-speed corners and long straights resulting in one of the highest average speeds of the year.

"There has been a great deal of analysis and hard work taking place at Brackley and Brixworth since we returned from Japan," continued Brawn. " I am pleased with the continued work ethic of the team and the determination to achieve our goal of second place in the championship.

"Both Nico and Lewis have been in the factory this week to assist with our preparations for the next two races and we are all looking forward to the challenge of securing strong finishes for both drivers."
