In May 2025, 195 cars took to the track in a single weekend: one year later, that record is nearly matched during another action-packed week filled with iconic events.


As tradition dictates, May is the month when the international motorsport calendar brings together many of its most important events. It is therefore no coincidence that it is also a special month for Tatuus, packed with key appointments that celebrate pure racing passion and, thanks to ever-increasing participation levels, continue to set new records.

This is exactly what happened just over a year ago, between May 2 and 4, 2025, when as many as 195 single-seaters took the start simultaneously across 9 championships in Asia, Europe, and America. The same scenario is about to repeat itself in 2026, once again approaching those record figures.

There will be 7 championships on track simultaneously from today through Sunday, for a total of 190 single-seaters battling across highly prestigious events.

From the Carb Night Classic, moved to Thursday due to weather conditions expected on what would have been the traditional Friday, to the F1 Academy round in Montreal alongside Formula 1, and including European commitments such as the Italian and British F4 championships, GB4, and the FIA FREC, it is impossible to identify a single most important round.

What is certain is that passion and excitement will not be missing over these four days marked in red on the Tatuus calendar.



USF2000 and USF Pro 2000 – Lucas Oil Indianapolis Raceway Park


This is the most anticipated event of the USF Pro Championships season, as well as the first to hit the track during this record weekend: the Carb Night Classic.

The iconic Lucas Oil Raceway Park, a 0.686-mile oval located just 11 km from the Indianapolis Speedway, was scheduled to host the USF2000 and USF Pro 2000 night races on Friday — the Freedom 75 and Freedom 90. However, due to adverse weather forecasts, all on-track activity has been moved to Thursday, thanks to the efficient organization of Andersen Promotions.

It will therefore be a long and intense day, with qualifying and races separated by just three hours, making mental and physical energy management a crucial factor. Which of today’s many talents will follow in the footsteps of drivers like Kyle Kirkwood, winner of the Freedom 75 in 2018 and currently second in the 2026 IndyCar standings?

F1 Academy – Montreal


The F1 Academy returns after the long break caused by the cancellation of the Jeddah round, and does so for the second consecutive year in the stunning setting of Montreal, once again alongside Formula 1.

The cancellation of Jeddah means the schedule for the drivers this weekend is more intense than usual, with three races in addition to qualifying and Friday practice, a format that will also be repeated in Austin, ensuring the total number of races in the season remains unchanged.

The results from the opening round in Shanghai bring a tight and open championship to Montreal, with Emma Felbermayr, Alisha Palmowski, and Nina Gademan separated by just 9 points. The Canadian round will be a new and important challenge for most of the field, with only 7 of the 18 drivers having previous experience at the circuit from 2025.


Qualifying Friday 18:00 EDT

Race 1 Saturday 09:45 EDT

Race 2 Saturday 18:05 EDT

Race 3 Sunday 10:45 EDT


The races will be broadcast live by official F1 Academy broadcasters worldwide



FIA Formula Regional European Championship – Zandvoort


The new era of the FIA FREC continues with its second round at Zandvoort. After opening in Styria, the European championship—fourth step in the FIA single-seater ladder to Formula 1—heads to the dunes near the Atlantic coast to either confirm or reshape the early-season order.

This will be a different weekend compared to the opener, with only two races on the schedule and a format closer to the 2025 season, with qualifying sessions on Saturday and Sunday mornings and races in the afternoons.

The standings are close, led by Reno Francot (CL Motorsport, 43 points), followed by Rashid Al Dhaheri (R-ace, Yas Heat livery) on 38, Kean Nakamura Berta on 34, and Sebastian Wheldon close behind on 30.


Zandvoort also marks the first half of a back-to-back, as the paddock heads to Spa-Francorchamps next week for another key round on two iconic and demanding circuits, where the new Tatuus T-326 will face one of its early major tests.

British F4 – Snetterton


The British F4 season continues its 2026 campaign and driver development mission, moving to the iconic and demanding Snetterton circuit in Norfolk.

The early part of the season has already established a clear benchmark in Dries Van Langendonck, who has taken two wins from six races and leads the championship by 23 points over Ethan Jeff-Hall. However, with 10 rounds in total, British F4 remains one of the longest and most competitive F4 championships in the world, ensuring plenty of action ahead.


Qualifying Saturday 10:20 BST

Race 1 Saturday 16:15 BST

Race 2 Sunday 10:40 BST

Race 3 Sunday 15:50 BST


Races will be streamed live on the official championship YouTube channel



Italian F4 Championship – Vallelunga


A record-breaking May continues for Italian F4. After the opening round featuring 48 cars on the grid, participation remains extremely high for the second round at Vallelunga.

Due to the large number of entries, this round will again feature four races, as seen not only at Misano but also in last year’s Vallelunga event, when Kean Nakamura Berta completed a streak of five consecutive victories that began in Misano.

For Alp Aksoy, who leads the standings with 82 points, the current streak is not wins but podiums (two wins and a third place at Misano). The young Turkish driver will aim to extend his consistency, while his closest rivals, Niccolò Maccagnani and David Cosma Cristofor, will try to close the gap of 16 and 21 points respectively.


Qualifying 1 Friday 18:10 CET

Qualifying 2 Friday 18:40 CET

GB4 Championship – Oulton Park


While the total number of Tatuus single-seaters competing this weekend is close to a record, the GB4 Championship round at Oulton Park features an official record grid of 29 cars—matching the season opener and marking the highest-ever number of formula cars at the circuit in 19 years (since British F3 in 2007).

The season opener at Silverstone delivered its usual spectacle. Young McLaren-backed talent Fred Green arrives at Oulton as championship leader, 10 points ahead of Enzo Hallman (Hillspeed, a previous Oulton winner), with other contenders including 2025 Oulton race winner Alex O’Grady.

As is often the case at Oulton Park, there will be no Sunday racing; however, the paddock will be open across Saturday and Monday, giving fans close access to teams and drivers.


Qualifying Saturday 11:40 BST

Race 1 Saturday 15:00 BST

Race 2 Monday 09:45 BST

Race 3 Monday 15:00 BST


Races will be streamed live on MSV

“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
“Motorsport works like magic, capable of inspiring that uniquely Italian determination to keep believing in something even when the numbers don’t add up.”
The words of CEO Giovanni Delfino in an interview with la Repubblica.

The CEO of Tatuus, ATM – Autotecnica Motori, and the Korus Group was featured in an interview published today in la Repubblica and written by Irene Saderini. During the conversation, he reflected on some of the most important and defining moments of his career, while also sharing his views on several aspects of the global motorsport industry.
The full interview is available on repubblica.it .

A Personal Journey A central theme of the interview is the CEO’s personal story, which began with his decision to pursue engineering studies and continued through a career marked by bold choices and decisive moments: “I don’t believe in luck; I believe in being able to seize it. When an opportunity comes your way, you have to recognize it. That said, it would be unfair to claim I wasn’t fortunate. I joined the company when I had virtually nothing. The founder allowed me to repay my debt over time, and I only finished paying the last installments two or three years ago.”
Delfino also spoke about his early years at Alfa Corse, where he developed his passion for experimentation and performance engineering: “At heart, I am a track engineer. I worked in the testing departments, where our job was to find that extra half horsepower from a finished product. My first experiences came in Alfa Romeo Touring Cars, with drivers such as Giovanardi, Tarquini and Larini competing against BMW and Mercedes. Sometimes those extra two horsepower were what won you the race.”

Formula 4 and Driver Development Among the key topics discussed was the production of Formula racing cars and engines, today one of the cornerstones of the Korus Group: “Everything starts with studying the regulations, which always leave room for interpretation—and success comes from finding the right one.” Speaking about Formula 4 engines, Delfino explained: “It all starts with a four-cylinder Fiat 500 Abarth unit. It must cost less than €16,500 due to the price cap and last 10,000 kilometres. My objective is to ensure that every engine performs the same.” The reward is seeing young talents progress step by step through the motorsport ladder and ultimately reach the highest levels of the sport: “It was particularly rewarding to see Andrea Kimi Antonelli begin his career in one of our cars.”

The Motorsport Industry The interview also included a broader reflection on the remarkable momentum motorsport is experiencing worldwide: “Motorsport sometimes works like a kind of magic, capable of overcoming marketing logic and keeping alive that uniquely Italian determination to believe in something even when the numbers don’t add up.”
Particularly representative of the Korus Group’s vision was Delfino’s perspective on internal combustion and electric powertrains: “For me, the smell of a winning engine is the smell of gasoline, hard work and sacrifice. A twelve-cylinder engine on track is like a violin—actually, an entire orchestra of violins. Racing is my world, and I find it difficult to see any of that emotion in batteries alone. Hybrid technology, however, is a different story. We are part of the FIA working group on the new regulations, and I find the hybrid approach very compelling.”

Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
Tatuus Celebrates the 500th T-421, the World’s Most Widely Used Formula 4 Car
The Lainate-based manufacturer has celebrated the production and delivery of the 500th chassis of the single-seater on which Kimi Antonelli and Arvid Lindblad developed their careers.

Born in 2021, the Tatuus T-421 reached its 500th unit produced and delivered in May 2026, once again confirming its status as one of the most manufactured and successful racing single-seaters worldwide. The milestone was celebrated by the Lainate-based brand together with all its employees and the sister companies of the Korus group, which contribute daily to the T-421 project: ATM–Autotecnica Motori, Breda Racing, and Next Solution Technologies.
Today, the T-421 is the most widely used Formula 4 car in the world, competing across 16 championships spanning Europe, the Americas, Asia, and Oceania. Behind its wheel, some of the most exciting talents in contemporary motorsport have developed, including Kimi Antonelli and Arvid Lindblad , who built the first steps of their single-seater careers in the second-generation Tatuus F4 before progressing all the way to the pinnacle of Formula 1.
“The 500th T-421 is not only a major milestone for Tatuus, but also an important achievement for the entire international motorsport ecosystem,” said Giovanni Delfino, CEO of Tatuus and the Korus Group. “With the introduction of Formula 4 in 2014, the FIA created a new pathway between karting and single-seaters, enabling drivers to arrive better prepared for higher categories. This model has established itself through years of significant growth in motorsport, during which many championships were launched and expanded, now reaching grids of nearly 50 cars per round with the second generation we celebrate today. These are figures that were difficult to imagine at the beginning of this journey, but which now define the everyday reality of many of the companies within the Korus Group.”
“Throughout Tatuus’ history, many of our models have achieved widespread adoption across global championships and have demonstrated unparalleled driver development capabilities,” added Gianfranco De Bellis, President of Tatuus and the Korus group. “The T-421 is writing an important chapter in the history of our brand and, together with the first-generation car, is now approaching 800 units produced. These volumes allow us to aim toward the milestone of 1,000 F4 single-seaters, a figure previously approached by the various Formula Renault models that marked a turning point in our history and in the development path of many drivers.”
As the second generation of Formula 4 single-seaters, the T-421 succeeded the T-014, which from 2014—the year Formula 4 was introduced—through 2021 was produced in just under 300 units. It represented the ideal platform for drivers transitioning from karting to single-seaters, and helped develop talents such as Lando Norris, Oscar Piastri, Max Verstappen, Isack Hadjar, Liam Lawson, Lance Stroll, Oliver Bearman, Gabriel Bortoleto, and Franco Colapinto.
The T-421 is just one of many examples of the cooperation that makes the Korus group one of the leading global ecosystems in motorsport engineering. The companies within the Group involved in the celebration have contributed to the project from day one, within a consolidated model of synergies that each year gives rise to new cars, powertrains, and solutions for motorsport.
Specifically, ATM–Autotecnica Motori developed and supplies the Abarth-derived inline four-cylinder engine that powers the car, while Breda Racing is responsible for a large portion of the components—such as the halo and suspension arms—as well as instrumentation required for managing the cars both on track and at HQ. Next Solution Technologies provides a significant part of the car’s electronic and electromechanical systems, in addition to supplying steering wheels and rain lights.
However, the milestone of 500 cars does not represent a finishing point for Tatuus. Production of the current model will continue through 2028 , when FIA regulations foresee the introduction of the third-generation car , on which the brands of the Korus Group are already actively working.
