After one season in the Audi TT Cup, with four race wins to his name, and one victory and third place overall in the 2017 ADAC TCR Germany, van der Linde contested his first season in GT3 racing in 2018 – and with great success. Together with his brother he claimed two race wins in the ADAC GT Masters, making a further four appearances on the podium and ending the year in second place overall, just one point behind the champion. He also gained experience in the IMSA WeatherTech SportsCar Championship, where he took victory in the GTD class at the final round of the season, the “Petit Le Mans”. In the Blancpain GT Series, he and his brother finished third behind the two BMW teams of Walkenhorst Motorsport and ROWE Racing at the 24 Hours of Spa-Francorchamps. He was also awarded the “Sean Edwards Trophy” for emerging young GT drivers at the end of the season. However, the icing on the cake was still to come at the end of 2018: the invitation from BMW Motorsport to attend the DTM Young Driver Test, at which he secured a seat for 2019 with an impressive display. As such, van der Linde had achieved his dream of racing in the DTM within just five years.
