In GT racing, Dirk Müller is regarded as one of the best in the world. This is reflected in his long list of successes in this discipline. He first took to the track in a sports car in 1997 and immediately showed his skills in the Porsche Carrera Cup, which he went on to win one year later. He also caused a sensation with excellent results at the endurance classics in Daytona (1998 and 1999) and Le Mans (1999).
He did not have to wait long for his first big title as Müller won the GT class in the 2000 American Le Mans Series, and became a BMW works driver the following year. He claimed one victory with the BMW M3 GTR in the ALMS before switching to touring car racing in 2002.
In his five seasons with Schnitzer Motorsport, Müller took 12 victories and narrowly missed out on the European Championship title in 2004 and the World Championship title one year later. He also remained successful on the endurance circuit and, alongside Jörg Müller and Hans-Joachim Stuck (DE), was part of the team that won the 24-hour race at the Nürburgring in 2004.
In 2007 Müller returned to the endurance circuit and immediately won the FIA GT Championship with Ferrari. The following year he made a comeback in the ALMS, finishing as the class runner-up and only narrowly missing out on his second overall victory. When BMW of North America was planning its ALMS comeback for 2009 with the racing version of the new BMW M3, Müller was the logical choice as driver.
After sixth place in his first year, his fine performances were a crucial factor in BMW Team RLL winning both the Team and Manufacturer titles in 2010. In Road America he claimed victory in the GT class alongside Joey Hand. This season, Müller will once again alternate with Hand behind the wheel of the #56 BMW M3 GT. In addition, he will also be gunning for more success for BMW Motorsport at the European endurance classics.
