The new design is a more focused version of the Viziv Performance saloon concept revealed at the Tokyo Motor Show last October, with revised bumpers and sills, some other small styling tweaks and the addition of a huge spoiler.
The original Viziv Performance was described by Subaru as a sports saloon drawing on the race and rally heritage of the Legacy, Impreza and WRX. Few technical details were released, save that it retained Subaru's traditional set-up of a boxer engine and symmetrical all-wheel drive.
This Viziv Performance STI, then, previews the next WRX STI hot hatch, which will be based on Subaru's new Global Platform and is due on sale in 2020. Subaru describes the concept as "embodying the brand's vision for the future of making cars that deliver enjoyment and peace of mind to its customers".
No technical details about the concept have been revealed, but the next WRX STI is expected to be a plug-in hybrid.
The most recent WRX STI, powered by a 305bhp 2.5-litre turbocharged boxer engine, went off sale in the UK at the end of last year.
