Sergio Perez says Sauber's strong early form in 2012 a boost for the team

The team has endured some tough times in recent years, coming close to dropping out of Formula 1 after BMW quit the sport in 2009 before being saved by founder Peter Sauber.

But this year, it lies fourth in the Constructors' Championship and has been a strong top 10 contender in all three races.

"It's great when you come to the circuit and you know that you have got good potential to make Q3 and to score points," said Perez.

"It's a good feeling and motivation, not only for myself but for the whole team.

"They have done an incredible job. They have been so motivated to make a good car and we have that."

Sauber scored only one point in China courtesy of Kamui Kobayashi's 10th place, with Perez finishing just behind him.

Despite the disappointing result, Perez is confident that the team will be able to improve on that in Bahrain, having shown strong pace in China last week.

"Our pace in Shanghai was very real," he said. "I didn't have the problem in the race [a loss of downforce produced by the front wing] I'm sure I could have fought for a podium.

"Bahrain is going to be a very different race weekend. I'm very confident and really looking forward to this race. I think we can have a good weekend."
