Subaru teases ultimate WRX STI

Set to be sold in Japan as the WRX STI TC 380, the machine features a range of special components which set it apart from regular models.

Based on Japan's 2.0-litre Subaru WRX STI, the new model benefits from a new turbo, exhaust and catalytic converter sourced through Japanese aftermarket firm HKS, along with a new intake and strut brace developed by former rally driver Toshihiro Arai.

Other elements include a carbon lip spoiler and special Recaro seats. 

The "TC 380" badge could be a reference to the car's engine output, which may be 380 horsepower, or 283kW (well up on the standard Japanese car's 227kW peak). The car takes inspiration from some of Subaru's rally and time-attack machines (pictured).

Australia is unlikely to receive the new model, which joins a long run of special cars only offered in Subaru's domestic market.

But we are in line to receive the next-gen WRX and STI, which will be based on the same platform as the latest Impreza and Forester. 

Tipped to offer a hybrid variant for the first time, the new model is unlikely to reach Australia before 2020.
