In this weekend's Chinese Grand Prix, Mercedes driver Lewis Hamilton fended off an early challenge from Ferrari's Sebastian Vettel to take a commanding win. The pair now lie tied for points at the sharp end of the standings.
But aside from the fact we've a healthy title battle on our hands, what else did we learn during the weekend's action? We run through the key things the racing in Shanghai revealed.

Last time out, this promise made by the FIA didn’t quite come to fruition, but that was because the Australian Grand Prix is held on a quasi-street circuit.

This year’s, set by Mercedes’ race-winner, Lewis Hamilton, was a 1:35.3.
