The single-seater that will take centre stage in the FIA Formula Regional European Championship and Formula Regional Middle East Championship, starting from 2026.

The result of an intense development effort by Tatuus Racing, the T-326  (subject to FIA homologation) represents the second generation of Formula Regional cars, marking the evolution of the previous T-318, which since 2019 has accompanied the rise of many talented drivers such as Andrea Kimi Antonelli, Gabriel Bortoleto, Isack Hadjar and Franco Colapinto on their path towards the higher echelons of motorsport.

Aerodynamics and Performance

Developed in full compliance with the latest FIA regulations, the T-326 brings a major step forward in terms of performance, aerodynamics, and safety. The new car has been designed to be lighter, more stable, and more responsive, featuring an improved chassis architecture and a revised suspension system that enhances steering precision and overall balance through corners. Aerodynamic efficiency, inspired by the latest trends from top-level single-seater series, ensures increased overall downforce and reduced wake effect, improving overtaking opportunities and on-track racing quality. From 2026, the Championship will adopt Pirelli tyres as single supplier, fitted on new 15-inch OZ wheels, ensuring technical continuity and uniform performance across the grid.

ATM163T Engine: Power, Efficiency and Innovation

The T-326 will be powered by the brand-new ATM163T engine, developed by Autotecnica Motori and derived from the Toyota G16E unit. This represents the first three-cylinder engine ever introduced in Formula Regional history, developed in collaboration with TOM’S to deliver high performance combined with improved energy efficiency and reliability. The project fully aligns with the new FIA standards for sustainability and technological innovation.

Safety and Ergonomics at the Core

The next-generation chassis complies with the highest FIA safety standards, featuring reinforced structures and updated components such as new-design front and rear crash boxes, anti-intrusion panels, and a revised roll-over protection system. Inside the cockpit, the ergonomic configuration has been optimised to ensure a comfortable driving position suitable for a wide range of drivers, improving visibility, comfort, and overall driving experience.

Technical Partnerships

The T-326 has been developed in collaboration with a strong network of top-tier motorsport partners: ARS Tech, Giga Composite, Carbonmade and La Compositi for carbon fibre components; Breda Racing, Eibach and Andreani for the suspension system; PFC Brakes and Tilton for the braking system. On-board electronics have been developed in partnership with Marelli, Next Solution and Nope Engineering, while the package is completed by the Sadev SLR-82 gearbox, Sabelt harnesses, OMP safety systems, and components from Galletto and Gieffe, forming a technical platform of absolute excellence.

Following an initial testing phase between August and October involving several professional drivers and test specialists, the new Tatuus T-326 is now ready to take to the track. Its official debut in 2026 will mark the beginning of a new chapter in the history of the category, reaffirming its mission to nurture the next generation of international motorsport talents.
