Keke Rosberg, after retiring from Formula One in 1986, remained involved in motorsport through driving commitments with Peugeot in the World Sports Car Championship in the early 1990s. He also personally entered the DTM in 1992, racing for Mercedes-AMG and subsequently Opel Team Joest before deciding to transition into team ownership. Team Rosberg GmbH was incorporated in 1994, with its debut as a constructor coming in 1995 as part of Opel's official DTM program.
In its debut season of 1995, Team Rosberg fielded Keke Rosberg himself alongside reigning champion Klaus Ludwig in Opel Calibra V6 coupes. The Calibra proved less competitive than the rival Mercedes C-Klasse. Ludwig secured Opel's only race win of the season and finished third in the drivers' championship; Team Rosberg was classified sixth in the teams' standings.
Rosberg retired from driving after 1995 to concentrate entirely on team management. As the DTM evolved into the short-lived International Touring Car Championship (ITC) in 1996, Ludwig moved to another Opel squad while JJ Lehto and Hans-Joachim Stuck joined Team Rosberg. Stuck won in Helsinki and finished sixth in the standings, while Lehto gathered several podiums without a race win. The ITC collapsed after 1996, ending this opening phase of the team's touring car career.
Following the ITC's demise, Team Rosberg managed Nissan's factory program in Germany's Super Tourenwagen Cup (STC) for 1997 and 1998, running a pair of Nissan Primeras for Roland Asch and Sascha Maassen. Asch was the highest-ranked Nissan driver in both seasons, finishing eighth overall in 1997 and again in 1998. When Nissan ended its factory STC participation after 1998, Rosberg took a sabbatical from touring cars to explore formula racing.
Team Rosberg entered formula competition in 1999, launching parallel programs in German Formula Three and the inaugural Formula BMW series. Pierre Kaffer drove the F3 entry to eighth in the standings. The Formula BMW operation produced strong results across subsequent seasons, most notably with Nico Rosberg — Keke's son — winning the Formula BMW ADAC championship in his 2002 rookie year under the VIVA Racing banner. Gary Paffett, who would later become DTM champion in 2005, won the German F3 championship with Rosberg in 2002, and the team secured the teams' title that same year, marking the outfit's most decorated season in open-wheel competition.
Team Rosberg's formula program wound down after 2005 when both the F3 Euroseries and Formula BMW ADAC campaigns were concluded, with the organisation refocusing exclusively on the revived DTM.
When the DTM was recreated in 2000, Team Rosberg partnered with Mercedes-AMG, operating CLK DTM cars for Darren Turner and Pedro Lamy. Rosberg finished seventh in the 2000 teams' standings. Results proved elusive in 2001, when only the factory AMG squad ran updated machinery; the team ranked eighth. For 2002 and 2003, the team again ran year-old Mercedes cars for Stefan Mücke, Christijan Albers, and Gary Paffett, serving as a customer and development squad within the Mercedes DTM structure. Both Albers and Paffett progressed to the factory AMG lineup in subsequent seasons. The Rosberg–Mercedes relationship concluded after 2004.
After a year away from touring cars in 2005, Team Rosberg returned to the DTM in 2006 as an Audi customer, fielding 2005-specification Audi A4 cars for Frank Stippler and Timo Scheider. The partnership proved productive: Scheider finished tenth in the drivers' standings and the team placed fourth in the teams' championship. In 2007, Mike Rockenfeller and Lucas Luhr drove for the team, with Rockenfeller finishing twelfth overall.
The team continued to develop within the Audi customer structure through the following decade. The 2019 season proved the most successful in the team's history: René Rast won seven races across nine race weekends, and Jamie Green added a further victory, propelling Team Rosberg to the DTM teams' championship title. Rast's own championship challenge was among the most dominant individual campaigns in the modern DTM era.
Team Rosberg stands as one of the few privateer organisations to have competed in the DTM across two completely separate eras, representing Opel, Mercedes, and Audi in succession. The team's role in developing drivers such as Gary Paffett, Nico Rosberg, Timo Scheider, and René Rast reflects its consistent position within the upper tier of German touring car and formula competition. The 2019 teams' championship represents the fulfilment of a nearly three-decade pursuit of DTM glory that began when Keke Rosberg first entered the series as a driver in 1992.
