Subaru Finally Ditches the EJ20: BRZ GT300 Goes Flat-Six for 2026 Super GT
After 28 years of the EJ20 flat-four running Super GT, Subaru's swapping in a new boxer six for the 2026 BRZ GT300. The move signals a serious commitment to staying competitive in Japan's premier racing series, though details on displacement and output are still locked down. This is the first major powertrain shift for Subaru's GT300 program since 1998.
Twenty-eight years is a hell of a run for one engine family in racing. The EJ20 earned its keep, but Super GT moves fast—Subaru just acknowledged that staying relevant means building something new.
