Subaru’s all-new sports sedan goes on sale today at Subaru dealers throughout Japan. The WRX S4 sports sedan combines Subaru’s state-of-the-art all-wheel drive (AWD) sports performance with unique overall safety features, superior environmental friendliness and refined quality. Subaru’s core value of AWD sports performance lies at the heart of the high-level fusion of these four attributes, enabling more drivers to comfortably enjoy breathtaking Subaru performance with peace of mind. The S4 tag denotes the four values of “sports performance”, “safety performance”, “smart driving” and “sophisticated feel”. Teamed with Sport Lineartronic transmission, the 2.0-liter high-performance direct injection turbo (DIT) engine maximizes output and torque for impressive power performance. As well as offering sporty, fun driving with plenty of direct feedback, the WRX S4 achieves advanced levels of environmental friendliness. Moreover, this is the first model in the WRX series to be equipped with Subaru’s own EyeSight driving assist system for enhanced overall safety. Comprehensive body and chassis enhancements have achieved a high-quality ride, greatly reducing driver burden to support safe and comfortable driving. Product concept: “Pure Power in Your Control” In developing the WRX S4, Subaru strived to create a new type of sports sedan, embodying the product concept for the new WRX series, “Pure Power in Your Control,” and enabling more drivers to easily enjoy its impressive performance. By teaming sports performance with high levels of safety, environmental friendliness, and ride comfort, Subaru succeeded in crafting an accessible sports sedan that can be enjoyed by all drivers while still offering all the excitement of a performance vehicle. Chassis and Body Chassis and body performance have been thoroughly enhanced so that drivers can better control the absolute speed of combining Symmetrical AWD with a turbo Boxer engine. Working to stiffen both body and suspension while optimizing suspension geometry has both quickened vehicle response to driver steering input and raised the limit performance for cornering. In addition, Multi-mode Vehicle Dynamics Control (VDC) and Active Torque Vectoring have been added for even more predictable, more enjoyable driving. Many hours of in-depth suspension tuning have resulted in a flat, comfortable ride. The electric power steering is employed with more rigid steering gearbox mounts for a improved fuel efficiency and a more direct steering feel. The first model in the WRX series to be equipped with an electric parking brake for extra convenience. Engine The WRX S4 is equipped with a new high performance 2.0-liter Horizontally-Opposed direct injection turbo “DIT” engine for high power with environmental friendliness.
