Exclusive to the Japanese market. Obviously.
This is the JDM variant of the 2015 Subaru WRX. Dubbed the S4, the model is exclusive to Japan and comes with some minor visual differences and enhanced performance. The most obvious exterior change is a set of new 18-inch alloys, said to be lighter and more rigid, while the four-door also sports a more prominent front lip spoiler, LED DRLs, faux carbon-fiber trim on the dash, as well as red stitching, metallic accents and piano black finishes.
Power comes from the same 2.0-liter turbo-four as its US counterpart, yet with 300 hp and 295 lb-ft of torque instead of 272 hp and 258 lb-ft. The JDM WRX also gets a Lineatronic CVT with fully automatic electronic control, as well as Subaru's all-wheel-drive system featuring Variable Torque Distribution. On sale in Japanese showrooms now, the WRX S4 is on offer alongside the WRX STI.
