British GP Practice

Posted on Friday 19 Jun 2009 and tagged with britain, silverstone.

Objectives P1
•   Analysis of new aero components
•   Mechanical set-up work

Objectives P2
•   Performance evaluations with low and high fuel loads
•   Further mechanical set-up work and tyre comparisons

Conclusions - Sam Michael, Technical Director
“That was a good Friday session. We ran through lots of checks with the new parts we‘ve brought here for this race. We’ll go through the data tonight, but everything is working well. We also completed our usual tyre evaluations and cooling checks.”

Nico Rosberg
Runs P1: 1 install (new prime), 8 (scrubbed prime), 6 (scrubbed prime), 11 (scrubbed prime)
Runs P2: 3 (scrubbed prime), 11 (new prime), 11 (new option), 4 (new option), 3 (scrubbed option)
“We tried a few things, especially with the car’s aerodynamics, and we definitely learned a lot. The wind made things quite difficult though so it wasn’t so straightforward to find the right set-up direction today, but we made the best of it. It’s always a compromise between the quick corners in the first sector and the slow corners in the last sector. Tyre-wise, maybe the option isn’t quite as good as we would have hoped, but it’s still the better tyre here.”

Kazuki Nakajima
Runs P1: 1 install (new prime), 8 (scrubbed prime), 6 (scrubbed prime), 5 (scrubbed prime)
Runs P2: 4 (scrubbed prime), 6 (new prime), 8 (new option), 10 (new option)
“Today’s sessions went well for us. I was caught up in quite a bit of traffic in the early runs, but managed to get some clear air later on. We tried many different set-ups with the car; some of which were quite interesting, so we now need to look at the data in preparation for tomorrow’s qualifying.”
