Sigma P1 Unveils New Prototype in Brazil Amid GT Series Cup Event
Interlagos, Brazil – The FIA World Endurance Championship (WEC) in Brazil featured a pivotal double-header for the GT Series Cup Brasil, showcasing a blend of GT3, GT4, and specialty one-make cars. Notably, the event also marked the debut of the Sigma P1 prototype, an innovative entry into the Brazilian motorsports landscape.
Technical Overview
The Sigma P1, revealed in the paddock, signifies an evolution of Brazilian sports prototypes. Founded in 2014 by mechanical engineers Pedro Fetter and Evandro Flesch, Sigma P1 aims to revitalize the prototype scene. Aiming for a competitive debut in 2026, the upcoming Sport Protótipo series will feature the Sigma P1 G5 Evo, promising GT3-level performance at approximately $170,000 USD.
The new prototype will utilize a 6.2-liter GM LT1 engine, delivering about 450 bhp. Notably, the vehicle will be simplified by employing a Sadev gearbox, shifting away from the more complex LMP3-derived systems. Each car will operate under a single team (ISM), ensuring uniformity and controlled adjustments.
Design Innovations
Weighing in at 1,000 kg, the Sigma P1 is optimized for ease of maintenance, with an emphasis on safety, which is paramount in high-speed racing. The chassis has been re-engineered, featuring an LMP3 standard front crashbox to enhance structural integrity. The absence of adjustable DRS systems has been compensated with a strong aerodynamic package, ensuring substantial downforce while maintaining serviceability.
Market Aspirations
Fetter and Flesch are strategically positioning Sigma P1 to sustain customer interest. The plan includes participation in the renowned Mil Milhas 1000 km race to validate the design further. “We have two cars already ordered and aim for a grid of 10 by our inaugural race,” stated Fetter, underscoring the enthusiasm surrounding the one-make series.
Conclusion
Following successful shakedown tests, including a flawless 50-lap demonstration, Sigma P1 is actively pursuing engagements with current GT3 teams. With high demand and promising discussions already underway, the pair maintain a forward-looking vision, including aspirations of becoming the first Brazilian manufacturer at Le Mans. The next few years will be critical for Sigma P1 as it vies to reshape Brazil’s prototype and endurance racing narrative.
