Sandro Holzem is a professional racing driver, FIA Silver-graded, competing in German-based endurance and single-seater racing. He raced for Project 1 Motorsport in the DTM, a national single-driver championship, and for Rinaldi Racing in the Prototype Winter Series, where he drove LMP3 prototypes across a two-country calendar. His most recent work came in ADAC GT Masters, a shared-car endurance series mixing amateurs with graded professionals.[1]

Holzem's indexed record spans two seasons from 2023 to 2024 and totals 14 starts across three series. In the Prototype Winter Series in 2024, he won two races and took three podiums from three rounds, finishing fourth in the championship standings. His nine DTM starts for Project 1 in 2023 yielded no podiums; he added one podium in two ADAC GT Masters starts the same year. He has beaten established professionals including Rene Rast, a three-time DTM champion, once, and Jack Aitken, a Formula Renault Eurocup champion with 76 Formula 2 starts, twice.[2]

In the DTM, Holzem usually finished behind Kelvin van der Linde and Thomas Preining, both Platinum-graded established professionals; van der Linde is the 2025 GT World Challenge Europe champion, and Preining won the 2023 DTM. His strongest performance came in the Prototype Winter Series, where his two wins and unbeaten record in the three-round season placed him ahead of a professional and semi-professional field.
