Subaru WRX STI JP-Spec 2015 4x4 2.0 Boxer-4 Turbo 308 cv 43 mkgf

(from Subaru Press Release) Subaru Launches All-New “WRX STI” in Japan.
Tokyo, August 25, 2014 - Fuji Heavy Industries Ltd. (FHI), the manufacturer of Subaru automobiles, has introduced the all-new Subaru “WRX STI” in Japan. Subaru’s high-performance sedan goes on sale today at Subaru dealers throughout Japan.

Embodying the WRX series product concept “Pure Power in Your Control” at the highest level, the WRX STI is the flagship model of the series. Every component of the vehicle, including body and chassis, has been refined and coordinated to achieve the ultimate in Subaru all-wheel drive (AWD) sports performance, enabling drivers to control the vehicle’s ample power at will. Standard equipment includes Subaru’s motorsport-bred turbocharged 2.0-liter Boxer engine and multimode Driver’s Control Center Differential (DCCD) system.

Specially developed suspension further enhances chassis rigidity to enhance steering response, rear grip, and flat ride. Handling characteristics honed to cope with driving conditions anywhere in the world, including the punishing track of Germany’s Nürburgring circuit, offer agile driver response and more precise and stable cornering, while also enhancing steering stability and ride comfort.
“Pure Power in Your Control”

The product concept “Pure Power in Your Control” was established during development of the new WRX series. This concept aims to reach an even higher order of “absolute speed” and “driving excitement” for sports sedans, the goal pursued in successive generations of WRX series. This product concept was embodied to maximize the potential of the turbo Boxer engine and the pursuit of ultimate control performance, allowing drivers to steer the vehicle exactly as they imagine. To this end, the body has been made lighter and more rigid, integrating extensive chassis reinforcements.
Chassis and Body

Symmetrical AWD-based chassis and body performance has been thoroughly enhanced to the hilt to squeeze every last drop of power out of the Horizontally-Opposed turbo engine. This is what makes “Pure Power in Your Control” possible.

-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.
-An exclusive inverted-strut front suspension system has further refined steering response.
-Steering has been made more precise with a more rigid steering system.

Engine

The new WRX STI is equipped with a 2.0-liter Horizontally-Opposed turbo engine, serving as a symbol of Subaru’s high performance and reliability, as perfected in motorsport. Through precise tuning, the engine produces an impressive 227 kW (308 PS) at 6,400 rpm and 422Nm (43.0 kgfm) of torque at 4,400 rpm.
Transmission

On the receiving end of the powerful Horizontally-Opposed engine, the WRX STI employs a reinforced six-speed manual transmission. Coupled with short throw shifting, the combination makes driving a thrill.
- Six-Speed Manual Transmission -

Compared to the previous 6MT, the new WRX STI transmission was given better tactile feedback with gears that lock solidly in place for a sportier shift feel. The WRX STI equipment package continues to come with the multi-mode DCCD system, a carryover from the previous model. This system allows the driver to freely select center differential control characteristics according to road conditions and driver’s preferences.
