“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.

Another key pillar of the Korus culture is its focus on employee well-being :
“We place great importance on ensuring that every talent can thrive in the best possible environment and with the best tools, while also nurturing the values and personal relationships outside professional life that contribute to happiness and positively influence our approach to work. ”
Throughout the day, employees from the eight companies took part in workshops and discussion sessions alongside Group management, exploring the practical meaning of Korus’ three core values and reflecting on how they permeate daily operations across different business areas and roles, all equally represented during the event.
The Tatuus HQ showroom provided the ideal setting for a business lunch, with tables arranged among the Group’s cars and products. The focus then shifted to karting, a sector that, from 2025 onward, uniquely characterises the Korus Group. An in-depth session explored the distinctive features of the karting world and the “Korus Kart ” companies, before the day concluded with a special hands-on experience aboard Birel karts.
