Technical chiefs from three of the leading Formula 1 teams have expressed their desire to retain the current rim size for tires in the sport in spite of a recent push to make changes in the future.
In a bid to make F1 more road-relevant, it was thought that the change would be made in 2017 upon the next overhaul of the technical regulations.
Pirelli has completed a number of tests using tires with an 18-inch rim in the past year, with the latest coming in a show-run using a GP2 car in Monaco two weeks ago.
French supplier Michelin has expressed an interest in returning to F1 in the event of a move from 13-inch to 18-inch rim tires.
However, speaking in Friday’s FIA press conference, technical bosses from Mercedes, Ferrari and McLaren said that they would prefer to stick with the current size of rim.
“I think the broad consensus is that going to bigger wheels is not a good direction,” Mercedes’ Paddy Lowe said.
“Certainly from a grip point of view it’s not positive. Like for like, such tires will have a lower grip and the weight will go up considerably so it’s not an attractive direction performance-wise, so I think generally we would intend to stick with the 13 inch wheels.”
McLaren’s Matt Morris said that any changes would be dealt with accordingly by the teams, but he did explain how the changes would go beyond just the rim size.
“It is a big change like Paddy said,” Morris said. “It’s not just the tire size, it’s all the other parts that change with that, all the brake internals and what have you.
“From our side, we relish change as any engineer does so yeah, if that is going to change, we have a great knack of finding the best way around it and then potentially it’s an area where if you do a good job you can be competitive, so we’re happy if that was to go ahead.”
Ferrari’s James Allison was quick to identify the difference between a change in the size of the tire rim and that of the actual tire, with the latter still being a possibility for the future.
“As Paddy said, the rim diameter is going to stay where it is but the width of the tire is probably still up for grabs,” Allison said. “We’re discussing what that ought to be along with all the other aspects of the rules for around about that time.
“I would say that sooner the better would be good for things like that. Tires are maybe the most complicated bit of the car and the bit of the car that we have the least data about because we’re not allowed, by regulation, to test them, either on the track or off the track.
“So sooner the better from our point of view but there’s still time from where we are today. So as long as we get on with it from here it will be fine.”
MOORESVILLE, N.C. – Inside this former textile mill, a retro building built in 1892 with massive floor-to-ceiling windows and sturdy brick, Toyota has planted a future seed with the GR Cup.
Once a hub for making cotton dye, the first floor has been turned into a factory that churned out spec sports cars for the past year as Toyota Racing Development prepares to launch its first single-make series.
The inaugural season of the Toyota Gazoo Racing GR Cup will begin this weekend at Sonoma Raceway, the first of seven SRO-sanctioned events (each with two races) featuring a field of homologated GR86 production models that have been modified for racing with stock engines.
Under the banner of its Gazoo Racing (a high-performance brand relatively new to North America but synonymous with Dakar Rally champion Nasser Al-Attiyah), Toyota will join Mazda, Porsche, Ferrari and Lamborghini as the latest automaker to run a single-make U.S. series (with Ford recently announcing plans for its own in the near future).
It’s grassroots-level amateur racing for manufacturers that are accustomed to racing at motorsports’ highest levels, but there are many benefits through competition, driver development and marketing despite the lower profile.
“It’s not the easiest thing or cheapest thing to do,” TRD executive commercial director Jack Irving told NBC Sports. “But there’s massive value to be a part of it and have our DNA in the cars. You get to race a bunch and get a bunch of data. You get to engage directly in feedback from the people beating those cars up.”
The GR86s being raced are very similar to the street versions that retail for about $35,000 at dealerships that annually sell several thousand.
“It’s a test of the car and your design,” Irving said. “We take an engineered vehicle designed to spec for the road and then apply our resources to make it race ready. Some of those things cross over.
“Everyone approaches it differently. It’s a marketing piece for us. It’s a development piece for drivers. We’re supporting grass roots racing. This is a very long-term deal for us. This isn’t something we’re doing two years and done. It’s got a long-term vision. There’s big value in it, and there’s a lot of responsibility with that, too.
“You’re ultimately supporting it. You’re not just selling cars into a series and hoping it goes well. You have to be involved in a very material way to make sure it goes off well and has your fingerprints and represents the brand.”
Early indications have been solid. The GR Cup cars were rolled out on iRacing in January and immediately became one of the platform’s most popular vehicles (with 212-horsepower engines, the cars handle well and are difficult to spin).
TRD has sold 33 cars for GR Cup with 31 racing in Sonoma, easily surpassing initial expectations.
“Our target was to sell 20 cars in the first year, and we could have sold 50 if not for supply chain issues with some vendors,” TRD president David Wilson told NBC Sports. “We basically came up with the idea of taking the GR86 and looking at what it would take to turn that into a little race car and do it affordably and competitively, and what’s come along with that is just a tremendous interest level. It seems like a market that perhaps has been underserved right now.”
The race cars start as production models that are shipped directly from the factory in Japan to a port in Charleston, South Carolina. After being trucked to the Mooresville facility, they are stripped and sent to Joe Gibbs Racing to be outfitted with a roll cage.
Upon return to TRD, the transmission and stock engine is added. The body remains virtually the same as the street version with a slightly altered hood, decklid and splitter for ride height and aerodynamics.
The cars mostly are customized to help manage the heat – the stock versions aren’t designed to handle the oil that sloshes around in the high-speed left- and right-hand turns on the road and street courses of the GR Cup schedule. TRD puts about two dozen parts on the cars, using Stratasys 3-D Printers to manufacture many on site (which allows flexibility for adjusting on the fly during R&D). In addition to help with cooling, many of the tweaks focus on allowing a limited number of setup changes.
“You don’t have a lot of ability to adjust these cars,” Irving said. “It was done on purpose. The intent was you have three spring sets, and you can adjust the shocks and do air pressure. That’s it. We seal the engine and components of it. We dyno everything. Everyone is within range to create as consistent a series as we can.
“Some of that is to mimic what Mazda did. They’ve done a really good job with their series. Porsche, Ferrari and other OEMs have done it very well. We had a learning that was easier to go through their book and see the Cliffs Notes version to get where we are.”
After taking delivery, GR Cup teams are responsible for transporting the cars to each track (and can buy up to three sets of Continental tires per event). Toyota brings two parts trucks to each track
THE SCHEDULE AND SCENE
After Sonoma, the GR Cup will visit Circuit of the Americas (May 5-7), Virginia International Raceway (June 16-18), the streets of Nashville (Aug. 4-6), Road America (Aug. 25-27), Sebring International Raceway (Sept. 22-24) and Indianapolis Motor Speedway (Oct. 6-8).
Though Nashville (IndyCar’s Music City Grand Prix) and Indy (SRO’s eight-hour Intercontinental Challenge) are part of weekends with bigger headliners, the GR Cup mostly will be the second-billed series (behind SRO’s Fanatech GT World Challenge) for events that will draw a few thousand. Sonoma had a crowd of about 4,000 last year, and SRO Motorsports America president Greg Gill said its events draw a maximum of about 13,000 over three days.
“There are some iconic venues, and the SRO it’s not IMSA,” Wilson said. “It’s got a different feel to it. It’s not the show. IMSA is kind of the show. I actually think it’s a good place for us to start, because it’s a little bit under the radar relatively speaking. It’s not a venue where you see the grandstands full of fans. It’s very much racers and their families. It’s got a neat vibe to it because it’s kind of small. So for our first effort as a single-make series, it’s the right place for us.”
Though the attendance will be much smaller, Toyota still is bringing a large hospitality and marketing activation area with two 56-foot trucks that will provide a central gathering area for the series.
Teams’ entry fees will include meals there and provide a place to connect with Toyota engineers and other officials.
“I think we have a very different way of engaging with our group of drivers, and this series is similar to that,” Irving said. “Knowing that this isn’t going to get 100K people watching, but we want to have a direct connection with the drivers and understand their feelings about car, how do we make it better and empower them to be brand ambassadors for GR.”
BUDGETS, PURSES AND TEAMS
Toyota has positioned the GR Cup as filling a price gap between the Mazda MX-5 Cup (a spec Miata Series known for high-quality racing at very low costs) and the Porsche Carrera Cup
“If you look at the ladder of MX5 to Porsche Cup, the difference in cost is massive,” TRD general manager Tyler Gibbs told NBC Sports. “We slot in closer to Miata than Porsche. We’ll slot another car in potentially in the future above that. It’s a good place for us from a price point perspective. Our road car is slightly more expensive than a Miata, so it makes sense our performance on the car is higher than Miata.”
A GR Cup car will cost $125,000. Full-season costs will vary depending on how much teams spend on equipment and transportation with estimates from $15-35K per event. So a competitive full season probably could be accomplished in the $250,000-$300,000 range.
“The goal was if you can ‘Six Pack’ it like Kenny Rogers and throw it in the back of a trailer, that would be amazing for us,” said Irving, referencing a movie about being an independent racer in NASCAR. “That would make it more of what we hoped it would turn into, just being as accessible as we possibly can make it.”
Toyota has tried to bridge the gap by posting a purse of $1 million for the season. Each race pays $12,000 to win (through $5,000 for eighth) with the season champion earning $50,000.
“Our hope was if you won, the prize money would cover the cost of that weekend,” Gibbs said. “We’re not all the way there. But almost there.”
Toyota also has posted an additional $5,000 (on top of prize money) to the highest-finishing woman in every race (which dovetails with SRO’s 50 percent female-led executive team structure).
“If you’re a female driver who wins, you could get very close to sustainable” and cover a team’s race weekend costs, Irving said.
There are four women (Mia Lovell, Toni Breidinger, Cat Lauren and Isabella Robusto) slated for the full schedule.
The 31 cars will be fielded across more than a dozen teams including Smooge Racing (which fields GT4 Supras in SRO) and Copeland Motorsports (with Tyler Gonzalez, a four-time winner in MX-5 Cup). After a test last month at the Charlotte Motor Speedway Roval, teams began taking delivery on Feb. 24.
THE SANCTIONING BODY
Toyota fields Lexus in the GT categories of the IMSA WeatherTech SportsCar Championship but elected to go with the SRO Motorsports Group (“SRO” stands for Stephane Ratel Organization; Ratel is the founder and CEO) as the sanctioning body for the GR Cup.
With a heavy focus on GT racing, SRO’s marquee events are 24-hour races at the Nurburgring in Germany and Spa in Belgium. In the United States, SRO primarily is focused on GT3 sprint racing, and Gill said it’s viewed as a “gateway to IMSA” and its endurance events.
In choosing SRO, Gibbs said “the schedule was a big part of it.” GR Cup races will be held almost exclusively on Saturday and Sunday mornings in a consistency that would have been difficult with IMSA (which runs a greater volume of bigger series).
“Our people can show up Friday, race Saturday and Sunday and be on the way home Sunday afternoon,” Gibbs said. “For our customer for this car, that was important. They still have jobs and particularly the younger drivers have to go to school. The SRO really fit us. They were very interested.”
Irving also was drawn to SRO’s flexibility with digital media right and free livestreams of races that Toyota can use on its platforms.
Said Irving: “It’s hard to get a schedule that made sense and having a break between races so an amateur can repair their cars and have a month to regroup was a big deal. The long-term vision of SRO was a big part of that. IMSA runs a lot of classes. How we fit in was difficult. Would they have done things to make it work, yeah. But they just didn’t work for the vision we were doing. This is its own thing for us.”
Gill said the SRO is focused on “customer racing” that balances individual interests against factory programs – while still putting an emphasis on the importance of manufacturers such as Toyota.
“We were very impressed with the development of sports car racing at Toyota and what they wanted to do for the brand and the very strategic way they looked at things,” Gill told NBC Sports. “We had enjoyed real success and had a lot of admiration for the programs that Honda and Mazda developed with sports car racing at the grass roots and entry level. We thought they’d done an excellent job. Toyota has taken it to another level and should be commended because it’s good for the entire industry.”
GAZOO RACING AND THE FUTURE
Irving said Toyota has set a goal of turning Gazoo Racing into the premier performance brand in the United States within a decade, and the GR Cup is part of that thrust.
Gazoo Racing is the baby of Toyota Motor Corp. president Akio Toyoda, who founded a separate company called “Garage Racing” while racing under a pseudonym for many years.
Toyoda, who eventually would race a Lexus LFA at Nurburgring, eventually transitioned the program into Gazoo Racing (Gazoo translates to photographs in Japanese; Toyoda often took pictures of vehicles he wanted to build and race) as he rose through the ranks of Toyota.
“The concept of the brand is we’re going to build cars that are fun to drive, not just for accountants,” Gibbs said.
Irving said the intent of GR is “the car is born on track and not the boardroom.” In order to be certified by Toyota for Gazoo Racing, the GR86 had to decrease its lap time by a certain percentage over its street model.
In the long-term, Irving said Toyota could work with another series to adapt the GR86 to endurance races. But in the short-term, there are plans to roll out a “dealer class,” possibly by its COTA round in May.
“That’s our version of a softball league with dealership principals who purchase cars and race against each other,” Wilson said with a laugh. “As competitive as dealers are, we’ll sell a lot of spare parts. It becomes a way to generate competition amongst our dealer body, and we’re going to have some fun with it.”
