The Toyota TS010 is a Group C prototype racing car developed by Toyota Motor Corporation for competition in the World Sportscar Championship (WSC) and the 24 Hours of Le Mans during the 1991 and 1992 seasons. It succeeded the earlier Toyota 90C‑V series and was the last sport‑scar prototype fielded by Toyota before the company withdrew from sports‑car racing in the mid‑1990s.
Development
- In response to the 1990 FIA regulation change that reduced the maximum fuel allowance for Group C cars, Toyota designed the TS010 around a new 3.5‑litre naturally aspirated V8 engine, the Toyota R‑V8, to comply with the emerging Formula 1‑derived engine formula for sports prototypes.
- The chassis was a carbon‑fiber monocoque constructed by the Dallara chassis manufacturer in partnership with Toyota’s European racing division, Toyota Team Europe (TTE), based in Cologne, Germany.
- Design emphasis was placed on aerodynamic efficiency, low weight, and reliability for endurance events.

Racing history
- 1991 World Sportscar Championship: The TS010 debuted at the 1991 24 Hours of Daytona, finishing second overall behind a Jaguar XJR‑14. During the 1991 season, the car secured several podium finishes, contributing to Toyota’s third‑place finish in the constructors’ championship.
- 1991 24 Hours of Le Mans: Toyota entered two TS010s; one finished third overall, while the other retired due to a mechanical failure.
- 1992 Season: With the FIA’s shift to the “LM‑P1” (Le Mans Prototype 1) class, the TS010 continued to compete. At the 1992 24 Hours of Le Mans, the TS010 achieved a class victory, finishing fourth overall. The season marked Toyota’s final appearance in top‑level endurance sport‑scar racing until the program’s revival in the 2000s with the GT500 and LMP entries.
Legacy
- The TS010 is regarded as a technologically significant project that demonstrated Toyota’s capability to develop competitive naturally aspirated V8 engines and carbon‑fiber chassis for endurance racing.
- Lessons learned from the TS010 program informed later Toyota motorsport endeavors, including the Toyota TS030, TS040, and TS050 Hybrid prototypes that competed in the FIA World Endurance Championship and the 24 Hours of Le Mans in the 2010s.
- A number of TS010 chassis survive in museum collections and private collections, notably displayed at the Toyota Automobile Museum in Japan and the National Museum of Motorsport in the United Kingdom.
