From single-seaters to paddock activities, the ACI Racing Weekend offers an immersive experience both on and off the track, with an exclusive Tatuus initiative designed to accompany fans throughout the entire event.


At the Autodromo Nazionale Monza, the roar of the engines won't be the only highlight of the ACI Racing Weekend. While the action on track will feature several championships—including the FIA Formula Regional European Championship and the Italian F4 Championship, both starring Tatuus single-seaters—the paddock will offer a packed programme of activities, turning the event into a true festival atmosphere.



Activities Around the Circuit


Fans will have the opportunity to meet the drivers during dedicated meet & greet sessions, while autograph sessions will provide the chance to take home a special memory from the weekend. Sim racing experiences, DJ sets, car displays and a dedicated kids' area will transform the circuit into a place to enjoy far beyond the racing, offering something for motorsport enthusiasts, families and first-time visitors alike.



The Tatuus Collection


Just when the weekend seems to have offered every possible experience, Tatuus adds one more reason to visit the paddock with an initiative designed to make each day part of a larger journey.


At the Tatuus motorhome, visitors will be able to collect a special limited-edition series of three commemorative cards, created exclusively for the Monza weekend. A different design will be available each day—Friday, Saturday and Sunday—allowing fans to complete the full collection over the course of the event.


Each card celebrates an iconic Tatuus milestone: the production of the 500th T-421 chassis, the launch of the new T-326, and Kimi Antonelli's successful 2022 Italian F4 Championship campaign.


Three days, three exclusive cards and one collection to complete throughout the weekend.

“From 2017 to Today: A Remarkable Growth Journey That Makes Me Proud”
“From 2017 to Today: A Remarkable Growth Journey That Makes Me Proud”

From the launch of the Group project in 2017 to the vision for the future: President Gianfranco De Bellis shares his thoughts during Mediobanca’s “Mid Corporate and Private Equity” event.
The Chairman of Korus Group , Gianfranco De Bellis , took part today in the event “Mid Corporate and Private Equity: Twenty Years of Transformation and Growth” , organized by Mediobanca and dedicated to the relationship between Italian mid-sized companies and private equity. His interview took place during a morning session that brought together private equity professionals and senior executives leading businesses backed by private equity funds, providing an opportunity to discuss growth strategies, value creation and the role of private equity in the development of Italian companies.

From Vision to Leadership
"I am very pleased to have embarked on this journey in 2017 together with our first investment fund," the Chairman said, reflecting on the evolution of Tatuus and the Group. "When I first met with the private equity investors, the idea I put on the table was to bring together Italy's niche expertise in motorsport. Bringing those capabilities together meant creating a group able to offer a true 360-degree solution. Back in 2017, Tatuus was a small company. Today, I am proud to say that 20 of the 22 current Formula 1 drivers developed through a Tatuus car, while our Group's turnover has grown significantly. For decades, the market for single-seater racing cars below Formula 1 was largely dominated by British manufacturers. Today, however, it is a sector that speaks Italian. That is something to reflect on, and it also challenges us to keep delivering something better in order to maintain our leadership position."

Building the Group
The audience showed particular interest when the Chairman described the process of building a motorsport group. "This is a very unique industry, and we were fortunate to find private equity partners who were genuinely passionate and willing to understand the dynamics of motorsport. Our first acquisition was an engine company, Autotecnica, whose CEO, Giovanni Delfino, was the ideal person to lead the entire Group thanks to his commercial and managerial expertise. The next step was the acquisition of Breda Racing, a company we had worked with for many years. This enabled us to strengthen our business and offer customers a Group capable of meeting every specific requirement in vehicle design and manufacturing. Throughout this process, we always preserved independent and differentiated business lines, ensuring the strength of each company while supporting healthy and diversified growth. Ownership later transitioned to The Equity Club, with whom we have built an outstanding relationship and who have brought great stability to the Group. Before private equity, we were almost navigating by sight, but over time we built a strong management team capable of turning our vision into reality."

Growth Built on People
The Chairman also highlighted the importance of people and the Group's commitment to investing in young talent. "The Covid period had a major impact, but motorsport responded extraordinarily well, returning to activity very quickly and triggering a phase of significant expansion. In less than ten years, we grew from Tatuus generating €13–14 million in revenue to a Group generating €150 million, while our workforce expanded from 20 employees to more than 300. It makes me proud to know that we have many outstanding young professionals in whom we have invested significantly, and who will carry forward the story of our brands and our Group with the same passion as those who founded them."

Looking Ahead
"Today we are able to take on major projects with a level of strength and structure that we could never have imagined in the past. Our goal is always to deliver the highest quality, both in our products and in our service, anywhere in the world and at any time, always placing the customer at the center of everything we do while nurturing the long-standing relationships that have brought our products to race on circuits across the globe. That is something to reflect on, and it also drives us to keep improving in order to maintain our leadership position." [...]

"It is no coincidence that the world turns to Italy to find quality in motorsport."
"It is no coincidence that the world turns to Italy to find quality in motorsport."

CEO Giovanni Delfino’s remarks at the Motor Valley Fest 2026
Motorsport is experiencing a period of strong vitality. Not only because of the results that continue to bring Italy back to the center of international competitions, but also because of the strength of an entire industrial system capable of transforming research, technology, and development into a competitive advantage recognized worldwide. These are some of the topics analyzed by Giovanni Delfino (CEO of the Korus Group and Tatuus) , starting from the concept of collaboration among different but complementary excellences.

A growing movement and an increasingly widespread demand for motorsport. “What we are experiencing is a demand for motorsport that is difficult to measure, but we are helped by some significant numbers, such as the 500 T-421 units recently celebrated by Tatuus and the 300 first-generation Formula 4 cars, along with all the other categories we supply. We are talking about a healthy movement that is clearly perceptible also in karting, where at every race we see hundreds of children showing determination and a strong desire to get into karts and compete. Today our priority is to continue producing and offering products to help these young drivers grow, so that they can eventually reach the top level of hypercars, F1, and IndyCar, with the awareness that it is not an easy or inexpensive path, but one to which we dedicate ourselves every day.”

The technological and industrial challenge of junior and entry categories. “Italian mechatronics is a benchmark and a point of reference. We produce and sell cars while respecting extremely strict price caps, with safety standards that must be guaranteed to young drivers racing at a very high competitive level. The effort is significant, but so is the satisfaction in seeing these results on track.”

Motorsport as an ecosystem of industrial collaboration. “The panel is called The Future of Racing and if I were asked what it means, fully understanding the depth of this title would require endless reasoning. But then I look around and I am joined in this panel by Pirelli, Marelli, Sabelt, and Ferrari, with whom we will be rivals in WEC but always friends. Many of them also collaborate on the T-421 project, which in itself is highly representative of what the future of racing stands for. I always recall with pleasure how we are on excellent terms with Dallara, with whom we share, without overlap, a specific area of activity such as the motorsport pyramid, which today represents an almost entirely Italian market.”

The role of Italy in motorsport “There are many OEMs that choose to work alongside Italian elite companies to develop their products, and this clearly demonstrates how strong Italy’s importance in motorsport is. It is no coincidence that from all over the world people look to Italy to find quality. For us, reaching a level of collaboration such as the one with McLaren has been an important step up; working with a manufacturer of this prestige is undoubtedly a source of pride and of absolute significance.”
Panel participants The panel held in Modena at the San Paolo complex featured representatives from several national and international motorsport organizations:
Marco Palmerini (MotoGP Vehicle Development Manager, Ducati) Lara Rodini (Global Sponsorships & Activation Director, Lenovo) Philippe Tramonde (Technical Director Motorsport, Michelin) Massimiliano Ortalli (VP, Market Unit Director, Automotive, Life Science, Manufacturing, Aerospace & Defence, Capgemini) Massimiliano Marsiaj (Executive Vice President, Sabelt S.p.A.) Riccardo De Filippi (CEO Motorsport, Marelli) Dario Marrafuschi (Head of Motorsport, Pirelli) Antonello Coletta (Ferrari) Vincent Biard (Head of Maserati Corse) Franco Cevolini (CEO, CRP Group) Alessandro Tucci (Executive Director Head of House of Grand Challenges, Aspire) Luca Ciancetti (Technical Director, Podium Advanced Technologies) [...]

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.

TOYOTA GAZOO Racing New Zealand has confirmed that the Castrol Toyota FR Oceania Trophy will adopt a new second-generation Formula Regional car starting from 2027, marking a key step in the evolution of the championship and in its role within the international single-seater ladder. The series will replace its current fleet of Toyota FT-60 cars, in use since 2020, with a new package based on the Tatuus T-326 chassis. The project continues the long-standing collaboration between TGRNZ and Tatuus, confirming a shared commitment to developing drivers, performance and technology through motorsport. The new car is aligned with FIA Formula Regional Gen 2 standards and is powered by an evolution of the 2.0-litre turbocharged 8AR-FTS engine already used in the championship. The unit delivers approximately 280 horsepower, combining performance, efficiency and reliability. The overall package meets the latest targets in terms of performance, efficiency and sustainability, while keeping driver development at its core. The push-to-pass system, introduced in 2026, remains an integral part of the car, further enhancing race dynamics. Pirelli continues as the official tyre supplier in line with international Formula Regional regulations.
