“It won’t be easy to do that again, the Ferraris will be quick, the Red Bulls, the Astons. I just hope we are in the mix and with the shake-up of the whole weekend, it’s probably the most exciting weekend so far.”
The exact developmental direction Mercedes has taken will be revealed when the cars take to the track on Friday.
However, with only one practice session available to gather data, Miami may be the more likely venue to see just how big a jump they have made.
