Retiring after the 1993 season of the original DTM series, Olaf Manthey began working for Persson Motorsport in 1994, which ran Mercedes race cars.

[7] That same year, Manthey, along with Australian racing team EMA Motorsport in a collaborative effort, also saw their first appearance in the Bathurst 12 Hour, participating with a Porsche 991.2 GT3 R as car #912 and Matt Campbell, Mathieu Jaminet, and Preining as their driver lineup.

On their second attempt, they won the 2024 edition of the Bathurst endurance race outright with their #912 entry and drivers Campbell, Ayhancan Güven, and Laurens Vanthoor.

[8][9] Manthey also ran a second #911 entry in the Pro-Am class with Yasser Shahin, Alessio Picariello, and Harry King, in which they also won.

Manthey Racing has been a regular participant in the 24 Hours of Nürburgring endurance event since 2006, the 2012 edition their only absence as Olaf Manthey decided to enter the International GT Open instead.The team entered the Nürburgring 24 Hours in 2006, with additional factory driver support from Porsche, running a 996-generation 911 GT3.

[11] Lucas Luhr, Timo Bernhard, Mike Rockenfeller, and Marcel Tiemann took victory for Manthey Racing in the event, and due to favorable conditions and stiff competition from rival cars, also achieved what was then a new overall distance record (3,832 km (2,381 mi) in 151 laps).

Manthey returned to the 2013 24 Hours of Nürburgring after being absent in the 2012 event, winning the SP7 class, finishing 7th overall with Bernhard, Dumas, Lieb, and Luhr.

In 2013, Manthey Racing worked with Porsche to help enter and represent the German manufacturer in the LM GTE Pro class of the FIA World Endurance Championship.

[20] The team entered two cars for the 2013 season with the newly-unveiled Porsche 911 RSR, and Jörg Bergmeister, Patrick Pilet, Timo Bernhard, Marc Lieb, Richard Lietz, and Romain Dumas were selected for the driving lineups.

[21] They would retain some of the driver lineup for that season from the previous year, but would replace Bernhard, Dumas, and Lieb with Frédéric Makowiecki, Nick Tandy, and Marco Holzer, as the former three would drive for Porsche's Le Mans Prototype team.

Weeks after the conclusion of the season, Manthey Racing announced that they would be campaigning the 2025 FIA World Endurance Championship with cars backed by 1st Phorm and Iron Dames respectively.

[28] Among the lineups, Lietz is retained for another season, now alongside Riccardo Pera and Ryan Hardwick, the latter making the move away from Proton Competition.
