Subaru appears to be moving forward with producing its STI Performance-B Concept. New trademark filings from Japan’s own intellectual property office recently surfaced, very clearly showing the concept in digital renderings.
While trademark and patent filings don’t necessarily confirm anything, they could provide another clue regarding Subaru’s intent to bring back its highly desired performance model.

Japan’s federal IPO office published the renderings earlier this month, which were very clearly filed by Subaru. But rather than showing a traditional WRX STI sedan, the digital photos show the familiar STI Performance-B Concept.
In the past, the Impreza WRX STI was available in several body forms, ranging from the standard sedan, to even a five-door hatchback and wagon. However, Subaru made the previous WRX STI in sedan form only.
