Mies is a real asset to the Ford Mustang GT3 programme after spending much of his racing career with Audi Sport where he achieved great success on the track, starting in his first season with the German marque when he won the 2009 FIA GT3 European Championship.
He joined the ADAC GT Masters Championship in 2010, a series that would prove to be a happy hunting ground as he took numerous race wins, ultimately winning the title in both 2016 and 2021.
Mies is a consecutive winner of the Bathurst 12 Hour race, finishing first in 2011 and 2012. It was in 2012 that he also became a Blancpain Endurance Series (now known as GT World Challenge Europe) Champion.
In 2015, Mies achieved one of his most notable victories, winning the Nürburgring 24 Hours – a feat he repeated in 2017. His career has taken him across the globe, with victories spanning iconic endurance races from the Nürburgring to Bathurst and the Dubai 24 Hours.
He made his debut in the Ford Mustang GT3 at Daytona in 2024, joining forces with Harry Tincknell and Mike Rockenfeller as the third driver in the No. 64 car. His 2024 season also included a full endurance cup campaign in GT World Challenge Europe with Proton Competition, piloting the Mustang GT3. He capped the season with an impressive guest appearance at Le Mans, where he drove the Mustang to a commendable fourth-place finish.
Mies returned to IMSA for the 2025 season – as a full-time driver in the No. 65. There, he helped Ford Racing to a class win in one of the most notable 24-hour endurance races in the world, the Rolex 24 At Daytona.
