"It's always very interesting to go out and see the cars on track, because you can compare the different cars, the way they handle, brake, corner, acceleration," he [Binotto] said. "From what I could see, our car looked well balanced in all kinds of corners, slow, medium and high-speed ones. It looked stable under braking, allowing the drivers to attack the corners in a very aggressive way. I'd say that's what pleased me most from seeing our car out on track."
It wasn't the same story for Mercedes. More than once Hamilton had to correct for a sudden snap of oversteer in high-speed corners -- a trait that was also a concern for the team throughout the opening week of testing. A significant upgrade for the second week helped smother the car in more downforce, but the balance front to rear remained biased towards the nose. Although that is a clear negative for Mercedes' single-lap pace last week, if the team can find a way to make the car's handling more neutral by Melbourne, the extra confidence found by the drivers could be worth a couple of tenths in qualifying.
