Nico Rosberg today set fastest with 1m20.130s.
Lewis Hamilton says after his final day of testing, he believes that Mercedes can win a race in this season. Also he added today he is not completely satisfied with winter testing.
"We need to keep pushing on; I've got to apply the pressure. So has Ross [Brawn]; so has Toto [Wolff]. We've got to continue to apply the pressure in the most important areas. Hamilton was quoted as saying by Autosport.
"I've got to explain to the team here where the car is weak; where we can improve. Then next week, when we are at the factory, we'll do some simulator running and then we'll try to improve the simulator.
"We also need to give the guys back feedback about the wind tunnel, and they're also getting questions about what's going on with the car. Then, when we get our next upgrades, if they say it's coming for China, we want it to be on for Malaysia. We have to apply the pressure all the time."
"I won't say I'm completely satisfied, if I felt that I had a rocket underneath me, then maybe [I would be], but I feel like I have a good foundation to work on.” The Brit added
"I think we've had a step forward with our upgrade, but everyone would have made an upgrade for here, and I think it's just a small step forward and we need more."
