Alexandros Margaritis has announced he is leaving the DTM after three seasons in the German series.
The Greek-German driver, who joined the championship in 2005, had admitted earlier this year that he had been frustrated by having only driven old cars during his stint in the DTM.
The 23-year-old says he will announce his plans for the future in a "foreseeable future".
"Retiring from DTM and splitting up with Mercedes-Benz Motorsport was my own decision," Margaritis said on the official DTM website.
"I'm going to inform my supporters on my new programme for the 2008 season in foreseeable future. I'm truly looking forward to the new challenges I'm going to face.
"And I'd like to use this opportunity to thank Mercedes-Benz Motorsport for their support and promotion in the past three years."
