Loek Hartog is a professional driver competing in multiclass endurance racing, racing GT3 cars in the GT World Challenge Europe Endurance Cup for Rutronik Racing. FIA Silver-graded, he won the 2024 Porsche Carrera Cup NA championship with Kellymoss, taking five wins from ten starts in that single-driver sprint series. His career spans eight seasons from 2019 to 2026 across multiple continents, mixing sprint racing in the Porsche Supercup and Carrera Cup with shared-driver endurance competition in the 24H Series, GT World Challenge, Asian Le Mans, and one appearance in the 2025 WEC.[1]
Hartog has taken twelve wins across eighty-eight starts. In the Porsche Carrera Cup he dominated the field completely, winning half his races and finishing on the podium in all but one. His endurance record is more measured; he has three wins in eight starts in the 24H Series and one win in six starts in GT World Challenge America, where he races in the Pro-Am class alongside amateurs. The 2025 season sees him racing the GT4 America Pro-Am class and the Asian Le Mans Series alongside his European commitments. In the WEC, he finished nineteenth in the championship standings across one round raced to date.[2]
Hartog regularly competes against Harry King, an established professional he matches closely across multiple series, and Lucas Auer, the 2024 GT World Challenge Europe champion and a Platinum-graded driver with 104 DTM starts and 97 Formula 1 starts, against whom he typically finishes behind. He has finished ahead of Dario Franchitti, a four-time IndyCar champion with 153 starts in that series, and Marcus Ericsson, a Platinum-graded driver with 132 IndyCar and 97 Formula 1 starts. Rutronik Racing, his main team in the European endurance series, has fielded Laurens Vanthoor, an established professional, among its roster of twenty-six drivers across four race wins.
