Following a teaser released a month ago, Subaru has unveiled the WRX S4 which will be sold exclusively in Japan.

Basically a JDM version of the 2015 WRX, the S4 looks virtually identical as the international version but comes with fresh 18-inch alloy wheels which promise to be more rigid and lighter. It also has a more prominent front spoiler lip, LED daytime running light bars along with carbon fiber-like finish on the dashboard and other similar minor tweaks such as red stitching, piano black finishes and metallic accents.

Under the hood it's the same four-cylinder, 2.0-liter direct-injection turbocharged engine but it delivers 300 PS (221 kW) at 5,600 rpm and 400 Nm (295 lb-ft) between 2,000 rpm and 4,800 rpm. As a reminder, the US-spec 2015MY WRX offers 272 PS (200 kW) and 349 Nm (258 lb-ft). In Japan, the engine is connected to a Lineartronic continuously variable transmission (CVT) with fully automatic electronic control whereas the American model is also available with a six-speed manual gearbox. All versions come with Subaru's newly developed Symmetrical All-Wheel Drive system featuring Variable Torque Distribution technology.

The JDM-spec WRX S4 is already available on order at Subaru's dealerships in Japan where customers can also place an order for the WRX STI.
