The team began its competitive career in junior formula categories during the late 1990s, establishing itself as a serious constructor and operator in European circuits. Its early focus on Formula Three gave it the technical expertise and driver development platform to nurture young talent. Signatech also supplied chassis for several regional formula series, including the Formula Future Fiat in Brazil in 2010 and 2011, and later the Formula 4 Sudamericana in 2014, demonstrating ambition beyond purely running its own entries.
Signature's junior era produced multiple championship-winning campaigns. The team won the FIA European Formula Three Cup in 1999 with Benoît Tréluyer, and in 2000 Jonathan Cochet took the French Formula Three Championship for the outfit while also winning the European Cup and the Masters of Formula 3, adding the Korea Super Prix in 2001. In 2002, Renaud Derlot won the European F3 Cup for the team.
In 2003, Signature claimed the team championship in the inaugural Formula Renault V6 Eurocup, with Tristan Gommendy and Kosuke Matsuura sharing driving duties. That same year the team moved into the Formula 3 Euro Series, and Nicolas Lapierre and Fabio Carbone delivered a 1–2 finish at the prestigious Macau Grand Prix.
The team repeated that Macau feat in 2009, when Edoardo Mortara and Jean-Karl Vernay crossed the line first and second. The 2010 Formula 3 Euro Series season was a particular high point: Mortara and Marco Wittmann finished first and second in the championship, winning eight races between them and securing the team title. In 2012, Signature withdrew from the Formula 3 Euro Series to concentrate entirely on sports car racing.
Signature began competing in the European Le Mans Series in 2009 in the LMP1 category, marking the start of a sustained push into prototype racing. In 2011, through cooperation with the Nissan GT Academy, Signatech finished second in LMP2 at the 24 Hours of Le Mans. The team placed tenth overall at the 2012 24 Hours of Le Mans in a Nissan-powered Oreca 03.
In 2013, Alpine partnered with Signatech to run an LMP2 car in the European Le Mans Series with Pierre Ragues and Nelson Panciatici, winning both the LMP2 Teams' and Drivers' championships that year. The relationship deepened when the team returned to the FIA World Endurance Championship in 2015. They claimed the LMP2 category championship in 2016 and again in the 2018–19 season.
In 2020, Signatech entered the European Le Mans Series as the Richard Mille Racing Team with an initially planned all-female lineup of Tatiana Calderón, Katherine Legge, and Sophia Flörsch. An injury to Legge led to André Negrão deputizing for the opening rounds, with Beitske Visser taking over for the remainder. The team then joined the 2021 FIA World Endurance Championship LMP2 class with an all-female crew of Calderón, Visser, and Flörsch.
Also in 2021, Signatech fielded a grandfathered Rebellion R13 in the Le Mans Hypercar class for the WEC season, finishing third overall at the 24 Hours of Le Mans. This Alpine-badged effort continued in 2022. For 2023, the team reverted to LMP2 machinery with two Oreca 07 entries.
Signatech returned to the Le Mans Hypercar class in 2024 with two Alpine A424 entries, competing as the Alpine Endurance Team. The squad finished fourth in the Hypercar standings for the season, with a third-place result at the 6 Hours of Fuji standing as the campaign's highlight. Alpine acquired a stake in Signatech in 2024, deepening a long-running commercial and sporting relationship that had defined the team's endurance racing identity for over a decade.
Signature's trajectory from a junior formula team shaping early careers of drivers such as Edoardo Mortara, Marco Wittmann, and Nicolas Lapierre, to a factory-aligned prototype team operating at the top level of the FIA World Endurance Championship, reflects a disciplined long-term evolution. The Alpine Endurance Team name it now carries represents the culmination of over two decades of chassis construction, driver development, and endurance expertise.
