The headline-grabbing entry from the Polish team’s stable is a full-season effort utilising a Mercedes-AMG GT3 Evo, which is sure to be a title contender in the overall and class standings.
Przemyslaw Bienkowski utilised the Mercedes to win the top GT class of Poland’s national championships in 2025, and will now take on an international competition in GT3 machinery for the first time. He will be joined in the GT Winter Series by PTT’s resident hotshoe, the vastly talented and experienced Mateusz Lisowski.
Alongside the familiar faces in the Mercedes is another returnee, Igor Klaja. After missing the 2025 GT Winter Series season, Klaja will return to the Cup 2 category, fielding his familiar and formidable Porsche 992 GT3 Cup.
Additional PTT entries may also join the grid, including a potential second Mercedes GT3 entry. As always, the well-prepared and competitively-driven fleet of vehicles from Krapkowice County will be a welcome addition to the GT Winter Series field.
The 2026 GT Winter Series promises to be yet another high-adrenaline variety show, showcasing the fastest GT racing cars prepared by teams from across Europe. The season begins at Portimão from January 15-18, and will proceed to offer a spectacle for live crowds and livestream viewers on a five-date tour across Iberia’s premier racing facilities.
