F1 organizers commissioned Hard Rock Stadium and Grand Prix managing director Tom Garfinkel to take over the relay track after the asphalt began to crack during last season’s opening race.
The well-known Tilke company was called upon to lay fresh asphalt.
This new surface helped Max Verstappen surpass FP2 with the lap record on Friday morning. His 1m 27.930s was 1.134s quicker than his 2022 pole time, although developments in the car also contributed to that.
Despite the improved performance, drivers complained of a lack of grip throughout Friday’s practice. Perez, who ran to fourth in the second quarter, likened it to running with an intermediate tire.
The Azerbaijan Grand Prix winner said: “The grip is very low there, especially in FP1.
“It feels like the interior conditions. We’re measuring the wet conditions and the interior conditions.
“I think the conditions[are why he’s struggling]. Knowing these low-grip conditions, especially what we’ve tried on FP1.”
Mercedes driver George Russell, who set the pace in the first practice, considered leaving Miami’s tarmac a “true outlier” unlike anywhere else on the calendar.
He said: “We’re going into an unknown track on Sunday and the track will be resurfaced.
“It still doesn’t perform as well as any other circuit. So, it’s a real outlier, which is cool in some ways.”
Drivers predicted the trend would continue in Miami as complaints about too few overtakes in the first round of the campaign led to spectator comments on a dull race.
At a track with 45 passes last season, drivers pointed to a lack of grip and Pirelli tires dropped marbles.
Russell continued: “The race is really hard because you can’t drive offline.
“You’ve seen some people, myself included, you take a wheel off and then you don’t have any grip.”

However, the drivers do expect the track to develop a lot faster and grip better throughout the weekend, but the situation remains “tricky and nasty” according to Nico Hulkenberg, who lost his rear bump into a wall in FP1.
Meanwhile, Lewis Hamilton added: “The grip on this new track is really low.
“It was interesting to see some of the downsides. It was slippery, especially the rear end.
“A lot of people, myself included, were constantly skidding and their tires were constantly overheating.
“We’re just trying to find a balance where the tires stay in the right place somehow, but they’re usually always above the temperature peak.”
The Barcelona-Catalunya circuit places high demands on the tires of the F1 cars. Pirelli therefore brought the new C1 tire to the Spanish Grand Prix for the first time this weekend. Pirelli also said teams must increase tire pressure by one point.
Hulkenberg, who has not raced for Barcelona at Renault since 2019, finished his second practice session on Friday afternoon behind Fernando Alonso and Red Bull pacesetter Max Verstappen.
The returning German still hadn’t completed the final corner at 170 mph, and he ended up clocking 0.27 seconds in 1 meter 14.177 seconds. The next 12 cars finished 15th behind his teammate Kevin Magnussen by 0.536 seconds.
Hulkenberg, who was only 18th in FP1, believes his performances in FP2 are “real”, although he expects other teams to find their pace in Saturday’s game.
He therefore called on his team to “remain calm and realistic” despite the exciting result.
Insight: What we learned from Friday’s practice for the F1 2023 Spanish GP
Hülkenberg said: “I think it looks real, but I guess the others didn’t play well, they didn’t play well.
“In particular, there are a lot of top cars and I think they’ll find something or pick it up overnight. We’ve got to be calm and realistic.”
Hulkenberg, who is yet to reach the podium in F1, believes Haas is better suited to Barcelona’s permanent circuit, having finished only 17th in Monaco last time around (with a 10-second penalty for a pit stop error), despite Use a car with an upgraded front wing in the Principality.
He continued: “For me it was important to have a good feeling in the car, a good rhythm.
“I managed to find it today and that’s the most important thing for me and for the driver.
“Obviously, I hope to have an equally good day tomorrow. Just squeezing out what we have.
“But it’s going to get tense again. Even with the Q3 battle, if you see it in midfield, there are still four or five teams and we’re all fighting over the same tarmac.
“It’s going to be a tough, tough battle again… Naturally here too, the car is just in a happier place. It immediately makes me feel better than a week ago in Monaco.”
He added: “It feels good, especially that lap. The new padding gives you more grip on the lap.
“Especially with FP2, I think we’ve gained some performance. In FP1, it’s not quite there yet.”
Meanwhile, Magnussen, who was seventh in FP1, believes a late set-up tweak affected his speed.
While Fernando Alonso is not yet in contention for a win in 2023, the Spaniard’s performance in a relatively strong Aston Martin looks like a comeback. Even with a slightly better car, the nearly 42-year-old F1 driver could take on Max Verstappen, a fight everyone including Pedro de la Rosa would love to see.
