Mercedes surprised the rest of the pack by topping the second practice at the Miami Grand Prix.
Having struggled to match the pace of the Red Bulls and Ferraris in the opening four rounds it was a welcome sight to see for the race fans though it remains to be seen if this will translate into on-track speed when the inaugural race starts.
It was Geroge Russell once again who outshone his teammate Lewis Hamilton to set the fastest time in FP2 with 1:29.938s a time 0.106s faster than FP1 leader Charles Leclerc.
Drivers opted for medium compounds for FP2 with track temperatures 10 degrees Celsius cooler than in FP1.
Carlos Sainz set the early benchmark on those tires (1m 31.463s) with championship leader Leclerc 0.167s back in P3.
Red Bull’s Sergio Perez, who spun at Turn 8 before setting his early flyer, split the two Ferraris.
Sainz then brought out the first red flag of the session, spinning and crashing into Turn 14 and ending his session in the wall with just over 40 minutes remaining
The stoppage left drivers 31 minutes to experiment.
Five minutes later, Max Verstappen – who had a new gearbox fitted to his car after a clash with the wall in FP1 limped the RB18 back to the pits with a hydraulics issue setting no time in the process.
With soft tires coming on Russell then displayed the strength of the hinted upgrades to the W13 as he shot to the top with a time of 1m 29.938s.
Perez took third for Red Bull, two-tenths off the pace, while Mercedes’ Lewis Hamilton was P4 and 0.241s behind his teammate Russell.
Alpine’s Fernando Alonso rounded out the top five (with a 0.434s gap to P1) as he looks to lead the midfield.
McLaren’s Lando Norris took P6, 0.597s down on Russell, with AlphaTauri driver Pierre Gasly a whisker behind in P7.
Zhou Guanyu took P8 with his Alfa Romeo teammate Valtteri Bottas having sat out the session after his FP1 spin.
In ninth was Alpine’s Esteban Ocon, with Haas’s Kevin Magnussen rounding out the top 10.
The teams will get another go at the layout of the new track tonight before qualifying for the race takes place on the same night.
