Mazaspeed is Mazda's in-house race and street car tuning arm. It began in 1968 as "Mazda Sports Corner", a tuning and racing operation run by Takayoshi Ohashi, who also ran Mazda's Tokyo distributor. They competed in numerous events at home and abroad, and they were also competitive at the 24 Hours of Le Mans races in the early 1980s with the 717, 727, and 737 before Mazda brought the group to Hiroshima in 1990. In 1991, Mazdaspeed's 787 won at Le Mans, a feat no other Japanese team has managed.
