Mazdaspeed

(often stylized in all-caps as MAZDASPEED) was Mazda's in-house performance division. The company was a grassroots racing team in Japan. Owned by Mazda Motor Corporation, they built production model vehicles, became involved in motorsports development, and offered performance parts and accessories. Mazda has phased out Mazdaspeed branding and has not offered a Mazdaspeed trim since the 2013 Mazdaspeed3.

==History== thumb|The Mazda 787B, winner of the [[1991 24 Hours of Le Mans.]] Mazdaspeed began in 1967 as "Mazda Sports Corner", an independent racing team and tuning 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. Mazda brought the racing team to Hiroshima in 1983, where the name became Mazdaspeed. In 1991 Mazdaspeed's 787B won at Le Mans a feat no other Japanese team managed until Toyota did in 2018. Mazdaspeed also prepared the Lantis & Familia for the JTCC between 1994 and 1996.
