The Subaru WRX S4 has officially been unveiled following a teaser image released just last month.

All-new Subaru WRX S4 sports sedan introduced in Japan

Set to be sold exclusively in Japan, the all-new sports sedan is according to the company, a JDM version of the 2015 WRX, and looks virtually identical as the international version. However it comes with new 18-inch alloy wheels, a more rigid suspension system with LED daytime running light bars, as well as a more prominent front spoiler lip.

Interior highlights include carbon fibre-like finishes on the dashboard, as well as red stitching, piano black finishes and metallic accents throughout the cabin. The car is also fitted with a flat-bottomed steering wheel, sporty bucket seats, leather trim on the gear lever, and a new boost gauge in the main multi-function display.

The WRX S4 packs a 2.0-litre turbocharged flat-four engine that delivers 221 kW at 5600 rpm and 400 Nm between 2 000 rpm and 4 800 rpm, which is more than the US-spec 2015MY WRX which offers 200 kW and 349 Nm.

Power is sent to all four wheels via a continuously variable transmission (CVT) and Subaru’s Symmetrical all-wheel drive system. Performance statistics were not published, but rumours have suggested the S4 can complete the 0-100 km/h task in 5.4 seconds.

The JDM-spec 2015 Subaru WRX S4 is already available on order at Subaru’s dealerships in Japan.
