Formula 1 will introduce new data into the halo television graphic that made its debut over the Azerbaijan Grand Prix weekend and experiment more with what information fans are given.

The aesthetics of the new-for-2018 controversial driver protection device have irritated some fans, while its prominence in some onboard camera positions was only realised at the first race.

Baku's opening practice session last month featured the first use of a new TV graphic over the top of the halo to display live speed, gear and engine rev information, as well as throttle and brake usage.

F1 has access to much more of teams' data though, from common elements such as G-forces, GPS and live sector times to much more sensitive information and measurements.

"We have a number of data sets and we're going to try and add as much as we can that is available," Dean Locke, F1's director of broadcast and media, told Autosport.

"Teams aren't going to give you anything that gives another team a competitive edge, but we can work with them.

"We still have things that we've already rolled out, like G-force and other elements, that we can build into that graphic.

"There will be new elements that we bring forward.

"We have such a short winter period to get all this finished, so what we are excited about is we can put more in.

"We can get that data, and various elements, to the viewing public and excite them a little bit."

Small modifications will be made to the halo graphic after its first live use, such as thickening the edge of the RPM counter to make it clearer to see.

Individual team graphics are unlikely despite a couple of halos featuring text that clashes with the data that gets displayed.

Locke added that F1 "took influences from film, from gaming" for the design, the introduction of which was delayed because some teams evolved the aerodynamic fairings on their halo.

"That's part of where we're going now," he said. "We're listening to these great marketing and research departments now that can reach out, which we didn't utilise before."

F1 was already considering using the halo's space to accommodate a graphic before the extent of its onboard camera intrusion became clear in Australia.

"We didn't want to put something out until it ticked all the boxes really, and obviously the big box was to do something different," Justin Laurie, F1 technical producer, told Autosport.

"It's a starting point to try new things, to take a space on the screen that could be used.

"It's not doing anything, there's no information or action in that area, so we wanted to utilise that space in an innovative and creative way.

"It seems to have created a popular response, which is a really good thing."

Formula One (F1) has approved a new Miami street circuit Grand Prix to be added to the calendar in 2019.

However, reigning World Champion Lewis Hamilton has suggested organizers might want to have a rethink before committing fully to the idea.

The Mercedes driver indicated ahead of this weekend's Spanish Grand Prix that he had been underwhelmed by what he had seen so far.

"I don't get why, for example, in golf, all the great golfers design golf courses," Hamilton told reporters. "You have not got any of the top racing drivers in history having ever designed a race track, and I don't get it. Not that any of us are designers, but they haven't asked for our input."

"Miami is a super-cool place and I was very excited to hear about it, but when I saw the layout I was like, meh. I think it could be a lot more fun," he added.

Miami city officials voted in favor of the F1 proposal on Thursday and it's expected the race would be in addition to the U.S. Grand Prix, which has taken place in Austin, Texas, since 2012 and was won by Hamilton on five of those six occasions.

Despite the reservations of the four-time world champion, the unanimous decision of the City of Miami Commission and Miami-Dade County was welcomed by the sport.

"Formula 1 in Miami represents a fantastic opportunity to bring the greatest racing spectacle on the planet to one of the world's most iconic cities, and we are delighted that the journey is underway," said Sean Bratches, F1's commercial managing director.

Miami City Commissioner Ken Russell gave a potential sneak preview of the location and layout of the track on social media last week. Most of the course runs through the port area and features a loop around the downtown American Airlines Arena along Biscayne Bay.

However, that seems to have only enhanced Hamilton's particular reservations.

"You have got two of the longest straights, but maybe when you drive it will be fun," Hamilton said. "I dread the thought of a street circuit like we had in Valencia, which wasn't a great street circuit."

That said, Hamilton still would like to see the idea succeed and would welcome the opportunity to have some input into what would make an exciting track layout.

Formula One Chairman Chase Carey said Wednesday in a Liberty Media conference call with analysts that he hoped and believed the race would happen.

"We think this race could probably be a real signature race for us on the schedule," he said.

Formula 1 teams are always striving for marginal gains – and that was evident ahead of the Spanish Grand Prix when Ferrari unveiled their halo-mounted mirrors. So what aerodynamic difference will this new design make? Mark Hughes explains…

Ferrari have certainly raised some eyebrows in Barcelona with their radical wing mirrors which for the first time are mounted on the halo – as allowed by the regulations post-China – and also incorporate dramatic-looking winglets for aerodynamic effect.

The mirrors, which retain the unique slot within the casing that redirects air to the radiator inlet, are only connected to the winglets sprouting from the halo through a narrow strip, thus qualifying the winglet as part of the mirror to meet the letter of the regulations.

This is a great example of how even a regulation change made as a safety measure can be used by the teams to create more performance. The FIA announced between the Chinese and Azerbaijan Grands Prix that henceforth mirrors could be mounted on the halo – in order to improve visibility for the driver.

Since the move in 2016 for wider and lower rear wings, rearward visibility has been especially restricted and it was felt that this may have been contributing to contact incidents on track. Moving the mirrors from the cockpit surround to the edges of the halo has allowed a better view above the rear wing.

But Ferrari aerodynamicists have been especially quick to exploit this. The angle of the winglet implies that it redirects some of the upward wash (created from the air hitting the front of the car) downwards.

Getting that part of the airflow angled back down earlier will give a better airflow to the edges of the rear wing and may even be used to further accelerate the air along the lower part of the bodywork, past the 'Coke-bottle' section.

This will likely give only marginal gains, but it illustrates the intensity of the search for every gram of performance that typifies F1.
