Day two of F1’s third pre-season test has come to an end in Barcelona, with reigning world champion Sebastian Vettel topping the times once more in Red Bull’s RB7.

Badger’s buddies Octane Photos were busy shooting the action once again, and have provided us with a proper look at the 2011 cars’ diffusers. Snapper Craig explains:

What would an F1 shoot be without a set of shapely rear ends…. okay, in this case it’s a comparison of the rear diffuser and wing setups on the grid. McLaren were spared the critique not by any kind of team loyalty, but because they were sat in the garage broken…..”

Check out the diffusers shots below, and see here for Octane Photos shots from yesterday’s test.
