Mercedes: Good feeling with the car 5 February, 2013 Nico Rosberg began the first pre-season test for Mercedes AMG Petronas today, following the launch of the team’s new car and a filming day in Jerez yesterday. Nico completed three runs this morning before an electrical problem caused the car to stop on track Unburnt fuel in the exhausts subsequently ignited but did not cause any serious damage Further investigation identified that the fault originated in a wiring loom The necessary modifications are now taking place ready for tomorrow Nico Rosberg: “At the start of winter testing, you often encounter small issues because the car you’re running is a brand new design. We had an electrical problem this morning and, once we had found the root cause, chose to modify the parts to make sure it didn’t happen again. Of course, at this time of year all you want to do is spend time in the car and get a feeling for how it’s working, but these hiccups are just part of the game. During the laps I completed this morning, I had a good feeling with the car and it felt solid.” Lewis Hamilton is due to drive on Wednesday for his first day of track testing with the team.
