The team was established by Gerold Ried in 1996, entering two GT2-specification Porsche 911 GT2s in the BPR Global GT Series. The early years brought modest results — one point in the inaugural 1997 FIA GT Championship season and occasional outings at Daytona — while Gerold and Christian Ried frequently shared driving duties as a father-son partnership. Between 1998 and 2003, the team raced consistently without major breakthrough results, running the same 911 GT2 before acquiring a Porsche 996 GT3-RS and stepping down to the N-GT class in 2003.
Progress accelerated from 2004 onward. The team finished fourth in the FIA GT Teams Championship in 2004 and second in 2005, a year in which the GT2 class was dominated by Gruppe M Racing. For 2006, the entry was renamed Team Felbermayr-Proton following the involvement of Horst Felbermayr Sr., and the team adopted a light blue livery it has used in broadly similar form ever since.
In 2007 the team moved into the Le Mans Series, fielding three cars. Car 77, driven by Marc Lieb and Xavier Pompidou, won three of six races and finished second in the Teams Championship. The year also marked the team's first 24 Hours of Le Mans appearance, partnering Seikel Motorsport with a Horst Felbermayr Jr./Sr. and Philip Collin entry that retired after 68 laps with an electrical problem.
The team's most successful sustained period came between 2009 and 2011. In 2009, the Lieb and Richard Lietz pairing in car 77 won three of five Le Mans Series races and clinched the Teams Championship by a single point over JMW Motorsport; Lieb and Lietz also took the Drivers Championship. The team repeated the Teams Championship title in 2010, winning three races again and finishing 21 points clear of AF Corse.
In 2010, the team also participated in the inaugural Intercontinental Le Mans Cup, winning the championship with 72 points from the European round at Silverstone and the Asian round at Zhuhai.
The defining result of the era came at the 2010 24 Hours of Le Mans, where car 77 — driven by Lieb, Lietz, and Wolf Henzler — took the GT2 class victory. It was Lieb's second Le Mans class win, Lietz's second class win, and Henzler's first.
For 2011, the Le Mans Series split the GT2 class into GTE Pro and GTE Am. The team entered in both categories, finishing third in each class in the Teams Championship. At Le Mans that year, the team ran three cars; car 77 in GTE Pro finished fourth in class, while car 63 in GTE Am was involved in a serious collision with a Corvette Racing car late in the race that injured Horst Felbermayr Sr.
The team entered the inaugural 2012 FIA World Endurance Championship season with two Porsche 911 GT3-RSRs, with Lieb and Lietz in the GTE Pro class and Christian Ried and Gianluca Roda in GTE Am.
In 2015 the team raced at Le Mans as Dempsey-Proton Racing in partnership with American actor and racing driver Patrick Dempsey's Dempsey Racing outfit. Car 77, driven by Marco Seefried, Patrick Long, and Patrick Dempsey, qualified fifth and finished second in the LM GTE Am class.
The team continues to campaign in the FIA World Endurance Championship and European Le Mans Series, running a customer Porsche 963 LMDh and a factory-supported Ford Mustang GT3 in endurance competition. Proton also fields entries in the IMSA SportsCar Championship and supports the Iron Dames all-female racing program with Porsche 911 entries. The long association with Porsche — stretching back to the team's founding — remains a defining characteristic of the outfit, though diversification with the Ford Mustang GT3 marks a new chapter in the team's history.
Proton Competition stands as one of the most enduring independent customer Porsche programs in international endurance racing. The team's back-to-back Le Mans Series championships in 2009 and 2010, the GT2 class victory at Le Mans in 2010, and consistent participation at Le Mans across two decades reflect a team that grew from a family enterprise into a respected professional endurance racing operation.
