History

Impul was established in 1980 by Kazuyoshi Hoshino after his driving career across Formula One, World Sportscar Championship, and Japanese domestic series. Early activities included tuning and preparation for Japanese Touring Car Championship and All-Japan Formula 2 Championship machinery, with the team expanding into full-time entries in All-Japan Sports Prototype Championship and Japanese GT Championship. Throughout the 1980s and 1990s Impul aligned with manufacturers such as Nissan and collaborated with engineering partners including Mugen Motorsports and chassis suppliers like March Engineering and Lola Cars. The team navigated shifts in Japanese motorsport governance by entering JAF-sanctioned championships and adapting to the formation of JGTC which later became Super GT. Into the 21st century, Impul consolidated efforts in Super GT and Formula Nippon (later Super Formula), while contributing to talent pathways alongside institutions such as Toyota Driver Development and Nismo Driver Development Program competitors.
