Mercedes has revealed that its 2012 F1 challenger - currently codenamed the F1 W03 - is set to make its on-track debut during the second winter test in Barcelona in February.

The announcement came on the same day that the team announced that it would run under the Mercedes AMG Petronas banner for next season in order to help promote the German marque's performance brand.

"We are very proud to reveal our new team name today," team boss Ross Brawn said. "It adds another strong performance element to our team's identity and, by virtue of being shared between Brackley and Brixworth, will forge even stronger links within our team.

"At the factory, we have been focused for some time on the challenge of 2012, and our very clear ambition to move forward up the grid next year. As always, the winter development and manufacturing processes are a trade-off between time for finding performance in the factory, and time for delivering that performance during pre-season testing.

"We believe that the decision to run the car at the second winter test is the optimum compromise for our design and development programme with F1 W03."
