WRX S4 details

The vehicle is said to be offered only in Japan, and although details remain a secret for now, the automaker released the teaser image above and said the vehicle is going to be more sophisticated than the new-generation 2015 WRX that was recently launched inSouth Africa.

The WRX was officially revealed during the Los Angeles Auto Show last year and is available in South Africa, with the WRX Premium coming in at R449 000, while the Lineartronic retails for R469 000. Both derivatives are powered by an all-new 2.0-litre flat four turbocharged engine with 197 kW and 350 Nm.

The new WRX S4 is expected to be powered by the same engine and feature Subaru’s Symmetrical all-wheel-drive system for optimum driving performance on the road, track and off-road driving situations.The sports sedan will also apparently achieve “unique overall safety performance” with features such as the next-generation EyeSight, “superior environmental friendliness” and “high-quality feel”.
