BMW not in bad shape, says Kubica

The German squad were on of the few who got significant mileage in their first test, thanks to staying at Valencia, where the weather allowed them to work properly despite strong winds.

The majority of their rivals have been hampered by poor weather in their tests.

Kubica reckons BMW are looking good so far, although he is aware that they will need to maximise their opportunities in order to beat the opposition.

"I think we are not in bad shape," Kubica said after testing at the Bahrain circuit on Wednesday.

"But as always to find the results we have to make sure we use our maximum potential of the car, the drivers, everything, to beat everybody, which will be not easy for sure, because in the end, if you go up against top teams everything has to work 100% or even better.

"If you want to win you have to be better than them. I think we are working well, but as I said it is difficult to say where we are."

The Pole admitted, however, that is it very hard to judge who is strong and who isn't so far, especially with the all the new rules introduced.

"I think, as always in testing it is very, very difficult to grasp, especially at this early stage. So nobody knows what other teams are doing, so I don't know," he added.

"In the end we will see the full potential and the true story of where we are only in Australia. But of course we can some, more or less, idea of where we are, but still it is more guessing than true information."
