Ageing will now improve Miami track surface, say F1 race organisers

The asphalt at the Hard Rock Stadium track was re-laid by circuit specialists Tilke for this year’s Miami Grand Prix, following problems in the inaugural 2022 event. 

However, the surface still posed issues for drivers with a lack of grip – especially off the racing line – which triggered a number of incidents throughout the weekend. 

One of the factors that limited the grip on offer was the decision by Miami race chiefs not to waterblast the surface – which helps remove a layer of bitumen and oil that is present on newly-laid asphalt. 

But while that posed some drawbacks for this weekend, Miami GP managing partner Tom Garfinkel says the move will now pay off as a more natural ageing of the surface will make it better for the long haul. 

“Without doing the water blasting, it’ll have a little more longevity,” explained Garfinkel. “It will also change over time. I think this climate with the sun and the humidity, and some other things will affect the track but, as it ages, it’s supposed to get better.” 

While the track surface was difficult for drivers in practice and qualifying, race winner Max Verstappen reckoned it was good enough by the race.  

“I think it improved quite a bit over the weekend,” said the Red Bull driver. “I was a little bit afraid, of course, with the rain that it would be a bit worse, but most places were quite okay.  

“It’s a street circuit. You can’t expect it to be amazing offline, that’s how it goes. But overall, I think it was a lot more fun to drive compared to last year. I think the tarmac has been a lot better. So yeah, it was absolutely fine. I think it’s not a bad track.” 

One other factor that did not help with the track surface was the lack of support race series, with only a single Porsche event alongside F1. That limited the amount of rubber that was being laid down over the race weekend to help improve grip. 

Asked if Miami was considering getting more support races on board for 2024, Garfinkel said: “We’re contemplating it. I think if you get more rubber on the track offline, you’re going to have better racing during the race. And it’s just more entertainment, more racing for the fans. So, if we can do that, that might make sense.” 

Chicane tweaks

Garfinkel also reckoned that changes Miami made to the configuration of the Turn 15/16 chicane also worked really well. 

Last year, the layout was criticised for being too…
