The new Mercedes W03 was revealed for the first time at Silverstone on Thursday, completing its initial run ahead of its first official test at Barcelona next week.
This spy shot of the car during a filming day shows it to feature a stepped nose, in common with almost the whole 2012 F1 grid and several other key differences from last year's machine.
Mercedes motorsport vice president Norbert Haug told AUTOSPORT: "The nose is the most discussed issue. It's a stepped nose as some have seen. It's a very nice solution, really, and a very dynamic one."
Michael Schumacher and Nico Rosberg drove the car. Filming days require that no more than 100km is completed and demonstration Pirelli tires are used.
