From autosport article, more important parts:
"Basically to understand the new tyres," he said of the point of the test. "To get the basics right, we can obviously do cambers, pressures, and you can understand the tyres. Yes ideally you have the new car, but ideally you want to keep the new car in the windtunnel as long as possible.
"So it is this compromise, or this strategy in order to perform the best and we chose a different way than the others. Let's say how it pays out."
The German was happy with how the new rear tyres performed, and said they were more fun than last year's rubber.
"The rear end tyre is certainly better, a real comparison is not possible because we only had new tyres on. They are definitely more consistent and more fun to drive."
Jerez Test Day 1: Mercedes report
07.02.2012 Jerez, Spain - Nico Rosberg (GER), Mercedes GP Petronas - Formula1 World Championship Pre-Season Testing - Jerez de la Frontera +++ Â© Copyright: Stange / RACE-PRESS.com
Feb.7 (Mercedes) Mercedes AMG Petronas began its 2012 testing programme in Jerez today, using the team’s 2011 car, the MGP W02.
- Nico Rosberg tested during the morning while Michael Schumacher was in the car for the afternoon
- Both drivers completed a set-up programme which focused on learning about the behaviour of the 2012 Pirelli tyres
- The reliable 2011 car also allowed the team to accumulate valuable mileage on a number of test items for the 2012 season
-Michael will continue the test programme tomorrow, with Nico in action again on Thursday.
“We made a very good start to our testing programme today and completed 56 laps this morning. I was driving the 2011 car, so it felt comfortable straightaway. We tested some different things in perfect weather conditions and started learning about the 2012 Pirelli tyres and how they work. I was really happy to be out on track in my Mercedes and I know that, back at the factory, our development of the new car is running according to our plan.”
“After a long break, it feels terrific being back in the car and hitting the circuit again. Our main job was to get a first impression of the tyres for 2012 and to start understanding them. They feel like a step forward, more consistent and comfortable to drive, and the biggest difference is with the rear tyre. Thanks to everybody at Pirelli for their good job this winter. Let’s see what we can learn tomorrow.”
