Subaru is on the cusp of launching a new Subaru WRX STI model but unfortunately, it will be sold exclusively in Japan.

The vehicle, set to be dubbed TC 380, will benefit from a plethora of upgrades over all other STI models with modifications overseen by former World Rally Championship driver Toshihiro Arai.

The Drive reports that the Subaru WRX STI TC 380 will be outfitted with a new GT III RS Sport turbo kit, a selection of HKS parts, a Super Turbo resonator, and a high-flow catalytic converter. Additionally, Arai Motorsport will have its way with the sports sedan, fitting a new RQA air filter and a front chassis brace developed in-house. All up, the car will reportedly pump out an impressive 380 hp from its 2.0-liter boxer engine. While it remains unclear what transmission the car will feature, we expect a manual gearbox to be the sole option.

Other modifications are expected to include a carbon fiber lip spoiler at the rear and a pair of Recaro racing seats up front.

It is claimed that the Japanese automaker will build just 50 units of the exclusive WRX STI TC 380 with each priced from a touch over 4.9 million yen, or roughly $43,900.

Subaru will hope that this new limited-run model will keep customers interested in the WRX family, despite the outgoing model nearing the end of its production run

Fortunately, and unlike rival Mitsubishi which killed the Evo, Subaru will release an entirely new-generation WRX in 2020, complete with a manual transmission and possibly some form of hybridization.
