Day One of F1's second pre-season test in Bahrain saw Mercedes-powered teams, by-and-large, pick up where they left off at Jerez, leading the way once more as Red Bull and their Renault-powered cohorts again struggled.
Adrian Sutil managed 82 laps in the Ferrari-powered Sauber to wind up sixth fastest - the German albeit spinning his C33, as happened more than once in Spain - with Marussia's MR03 managing just three laps in the hands of Jules Bianchi.
