The Rebellion R13 is a sports prototype racing car built by French constructor Oreca on behalf of Swiss-based team Rebellion Racing. It is a variation of Oreca 07, created to compete in LMP1 class. It would later be renamed by Alpine to Alpine A480 when it was rebadged to run grandfathered into the Hypercar class in 2021.

The R13 debuted in the FIA World Endurance Championship during its Super Season. Over the course of the season it achieved victory and fastest lap at the 2018 6 Hours of Silverstone, with further podiums at both Spa races, Fuji and the 2018 24 Hours of Le Mans, for a total of 6 for the season. Rebellion finished in 2nd place in the World Endurance LMP1 Championship with 134 points, making the R13 the best of the non-hybrid cars.

For the 2019-20 season, Rebellion reduced their full-season effort to a single car; the #1 driven by Menezes, Nato and Senna, with a second car appearing in select European races. This would later translate to a second R13, the #3, appearing in the 2019 4 Hours of Silverstone, where it finished 3rd and the 2019 24 Hours of Le Mans, where it finished 4th, though those results would not count towards the championship as only the #1 was eligible for points.

For that season, the WEC introduced a system of success ballast, which slowed down cars' performance according to their results in the championship, with the aim of equaling the performance of non-hybrid cars, the R13 and the Ginetta G60-LT-P1, with that of the Toyota TS050 Hybrid. This system allowed the R13 to be more competitive to the TS050, and the #1 Rebellion would take 2 victories during the season at Shanghai and at Austin.

At Shanghai, Rebellion would also become the first privateer team to get an overall pole position in WEC history, with that being also the first of the 4 consecutive pole positions the R13 would take during the season, with the rest coming in Bahrain, Austin, and Spa. The car would also set 3 fastest laps during the season, at Austin, Spa and Le Mans. Rebellion would skip the season finale at Bahrain after Toyota clinched the LMP1 teams' title at Le Mans, finishing second with 145 points and having scored podiums at all 7 rounds of the season it had been a part of.

On September 10th 2020, Auto Hebdo reported that the Signatech Alpine team competing in LMP2 during the 2019-20 WEC season would step up to the new Le Mans Hypercar class with a re-badged R13, given that the Hypercar rules allowed for non-hybrid LMP1 cars to be run in the class in the first year of competition.

The report was then confirmed by Alpine on September 12th. On January 21st 2021, the entry list for the 2021 FIA World Endurance Championship season was released, where the entry was confirmed and the car rename to Alpine A480 made official, with André Negrão being one of the drivers. The rest of the lineup was announced on January 26, with Nicolas Lapierre and Matthieu Vaxivière joining Negrão.

One of the features of the new Hypercar class for the 2021 WEC season was the addition of a Balance of Performance (BoP) system to ensure parity between entrants in the top class. As a result of the BoP system, ahead of the Prologue at Spa, which served as preseason testing for the contestants of the 2021 season, the A480's weight was increased to 930 kg and its peak power output reduced to 603 bhp (450 kW).

The changes had the objective of bringing down the LMP1's performance to the level of the cars made according to the slower Hypercar regulations, mainly the Toyota GR010 Hybrid, which was heavier but more powerful.
