F1: Miami GP Preview

Plans to add a second grand prix in the United States have been several years in the making, with Miami, Florida, eventually pinpointed as the desirable location. After further discussions the area around the Hard Rock Stadium, in Miami Gardens, was selected.

Hard Rock Stadium is the home of NFL’s Miami Dolphins, Miami Hurricanes soccer team and tennis’ Miami Open, and has hosted the prestigious Super Bowl on six occasions, most recently in 2020.

The Miami International Autodrome can now be added to the Hard Rock Stadium’s impressive sporting portfolio, with Formula 1’s Miami Grand Prix contracted through the next decade. Miami’s round comes in addition to the annual United States Grand Prix, at Austin’s Circuit of the Americas, which will take place in October, marking the first time since 1984 that two rounds have been held in the country.

Miami International Autodrome will also become the 11th different venue to host Formula 1 in the United States, more than any other country in the world.

The 5.41km 19-turn wall-lined circuit, named the Miami International Autodrome, utilizes the land on the Hard Rock Stadium campus. The circuit has been designed in conjunction with Formula 1 officials in order to create the best fast and flowing layout, as well as offering maximum opportunities for racing, with three DRS zones located around the track.

The start/finish line and pit lane will be located adjacent to the Hard Rock Stadium, where the likes of Taylor Swift, The Rolling Stones and U2 once played, and which will now reverberate to the sound of Formula 1 machinery. Formula 1 is ready to thrive in ‘The 305’.

Fact File: Miami Grand Prix

The Miami International Autodrome is a 5.412 km temporary circuit located in and around the Hard Rock Stadium complex – home to the NFL’s Miami Dolphins.
The Miami Grand Prix is one of two races in the USA this season, alongside the United States Grand Prix at the Circuit of the Americas in Texas. It is the 11th track to host a Formula One race in the USA.
The track is very narrow in some places compared to standard, permanent racetracks, particularly around the third sector. This will create a higher chance of Safety Car and Virtual Safety Car deployment as a result, due to it being more difficult to remove cars or debris.
We’re expecting 56% of the lap time (and 71% of the lap distance) to be taken at full throttle, on the lower end of the scale when it comes to the percentage figures for 2022’s F1 tracks.
Top speeds at the track are anticipated to reach a maximum of 324 km/h, while drivers are expected to change gear 40 times during the course of a lap.

What Can We Expect from the Miami International Autodrome?

This weekend, Formula One heads to Miami for the first time, with the temporary Miami International Autodrome hosting Round 5 of the 2022 Formula One season.

It’s a brand-new track and challenge for F1, so what can we expect?

What’s the track like?
The 5.412 km venue is located around the Hard Rock Stadium in Miami, featuring 19 corners, 12 left-handers and seven right. The layout is interesting, because it features many low and high-speed corners, but not very many in the mid-range. There are also several long straights and three DRS zones.

Because the slow corners are often followed by long straights, low-speed traction on corner exits will be important and a compromise is required with the car set-up. You want a high ride height with high downforce for the fast corners early on, a low drag set-up for the long straights and then a lower ride height with a high downforce level for the twisty sections. So, you must weigh up where the priorities are and what will get you the most lap time.

The sectors are all quite different. Sector one is dominated by faster, sweeping turns, while the second includes more of the slower turns. Sector three is dominated by the long back straight and the hairpin. Track evolution on the new surface is likely to be high, so lap times will be tumbling as the weekend progresses.

Surprisingly, the track’s characteristics share a few similarities with venues like Barcelona, in that the high-speed corners are early in the lap, therefore heating up the tires, and the end of the lap features twisty corners where the hot tires suffer – as there is no grip left. However, tire overheating might be a bit easier than in Barcelona, due to Miami’s long straights.

Given it is a brand-new track, we have no historical data, so it is a complete step into the unknown for all of the teams and drivers. The focus in the build-up has been on computer and driver-in-loop simulations with the limited information available to us, to try and get as close a guide as possible to what we can expect when we hit the track in Miami.

Both drivers have spent time in the simulator after the last round in Imola to get up to speed with the track layout and find a good base set-up for the first practice session. And it’ll then be important to build on that set-up as the weekend progresses, to get the car into a good working window.

Will it be a good track for racing?
The fact there are three long straights each with DRS zones and each leading into slow corners, does bode well in terms of overtaking opportunities. Turn 11 and Turn 17 will likely be the key places to watch out for.

The track is also quite narrow in some places, compared to permanent tracks. While this does make it harder to race side-by-side, it may prove important in terms of strategy and the opportunity to make places because cars and debris will be harder to clear. The likelihood of a Safety Car or Virtual Safety Car is high.

We have seen encouraging signs of drivers finding these 2022 cars easier to follow and that will be useful around a tight street track like Miami, where there are some fast and twisty corner sections leading onto straights. Hot temperatures are an important factor here too, as keeping the cars cool in traffic will be a challenge and may lead to drivers backing off to cool the brakes and Power Units.

Expectations can be very different to reality and wheel-to-wheel racing isn’t something we can simulate in our pre-race preparations, so we’ll have to wait and see how things progress over the race weekend.

What will the weather be like in Miami?
We expect conditions in Miami to be very warm, in the high 20s and even up to 30°C. And that’s just the air temperature, with track temperatures getting much hotter. It’s also anticipated to be dry, with rain rarely falling there in May. But we all know the weather can surprise us…

Interestingly, the weekend schedule means first practice takes place earlier than the race start time, practice two is later, while neither match qualifying either. So teams will have zero opportunity to test the tires and the car in the same track conditions as we’ll have for qualifying and the race.

The final section of FP1 will be the closest we get to race conditions and will therefore be unusually important, in order to collect useful data.

A new circuit always a presents an exciting challenge to the drivers and engineers. Although the drivers will learn the circuit very quickly, the behavior of the tires, the initial aging of the asphalt and the local conditions will ensure that there is a lot for the engineers to optimize throughout the weekend.

The Miami International Autodrome is a new circuit, which features several long straights, two fast corner sequences and one low-speed twisty section. This is all within a 5.4km anti-clockwise layout. There will be compromises to be made between the various sections of the track and so the team will have quite a task to find the best overall lap time.

Pirelli have provided compounds from the middle of their range, which is the same as in Imola. These are expected to suit the circuit layout quite well, although the exact tire behavior will depend on the track temperature and the chosen setup. It is this interaction between setup and tire behavior that will provide the drivers and engineers the biggest challenge of the weekend.

The weather looks likely to be hot and sunny with a small chance of thundery showers, and with the key sessions taking place in the mid to late afternoon, it could be quite punishing for the cars, tires and drivers.

Pirelli’s Perspective

For the very first visit to the eagerly-anticipated Miami street circuit, Pirelli has chosen the three tires in the middle of the range: P Zero White hard is the C2, P Zero Yellow medium is the C3, and P Zero Red soft is the C4. This combination is the most commonly-used one all year, and also the most versatile.
The 5.41-kilometre Miami International Autodrome is set in the Hard Rock Stadium Complex in Miami Gardens – the home of the Miami Dolphins – with 19 corners, three straights, elevation changes and a chicane. Top speeds are expected to be in the region of 320kph with an average of around 223kph and drivers on full throttle for approximately 58% of the lap. Turns 11 and 17 are the two main overtaking opportunities, with three DRS zones.
With the 11th venue to host a grand prix in the USA being brand new to everyone, Pirelli has had to rely on simulation data to come up with the tire nominations. This information indicates that the tires in the middle of the range will be most suited to the 57-lap race, with smooth asphalt that offers reasonable grip and the forces at work on the tires being about average for the season.
The brand new asphalt is likely to lead to a high degree of track evolution, especially at the start of the weekend, with the Porsche Challenge and W Series as support events. The weather could be unpredictable, with ambient temperatures of around 20 degrees and quite a high risk of rain and wind on the Florida coast at this time of year.

Mario Isola, Pirelli Motorsports Boss Perspective

“There’s been a huge buzz of excitement around the first Miami Grand Prix, where the track has some similarities to Jeddah, although there are some parts that are slower and more technical than Saudi Arabia: especially the section from Turns 11 to 16. The rest is a very quick layout, running anti-clockwise, which puts the emphasis on the tires on the right hand side of the car. We’re expecting the usual rapid track evolution and a smooth surface with the new asphalt, but the track has been jet-washed at high pressure, which means that it should offer quite good grip from the beginning. Because it’s a fast track the cars are likely to run a low to medium downforce set-up, which could lead to a bit of sliding in the high-speed corners on the hard compounds in particular. For any new track our choice tends to be on the conservative side, so it will be interest to confront the simulations with real data.”
