Test day 1 Perez did a 21.1 that he cut the chicane but earlier today (10th of march) he sat a 21.7 that wasn't cutted. Thats some proper qualli pace. Best time for a sauber last year in the race weekend was a 1:21.672 in practise session 2.
and also true about the sponsor thingy, they need some. And same as last year.
On the live text commentary for the testing days:
"Before the Sauber fans get too excited, remember this time last year the Swiss squad also ran an 'aggressive' testing programme, we all tipped Sauber as a dark horse and then Bahrain came..."
Yeah, I thought the same, when they are trying these crazy things it must mean they are desperate for some performance, most likely trying to copy redbulls 0.00001m off the ground front wing :P
