In 1996 he raced in the full Deutsche Tourenwagen Meisterschaft International Touring Car Championship, driving an Opel Calibra V6.

Alzen, who was leading the race at the time, barely limped to 2nd place after crashing with Abt's teammate Kris Nissen, whom he was trying to lap seconds earlier at the chicane.

Uwe Alzen set the lap record there with this Turbo at 8:09[permanent dead link‍], about 10 seconds faster than the factory cars of Opel and Audi from the DTM, as well as the BMW M3 V8 GTR of Schnitzer Motorsport.

He also has beaten them for the pole positions, yet his car failed at the start of the 2005 wet race due to electronic problems, prompting another very emotional interview.

In January 2012 Alzen is confirmed for a full season driving a BMW in the American Le Mans Series sharing a car with Jörg Müller.
