Debuting at the Tokyo Auto Show in October 2007, WRX STI versions build further on the standard WRX cars. The STI available in Japan is fitted with the 2.0-liter EJ207 engine with twin scroll turbocharger generating 227 kW (308 PS). Export markets receive the higher-displacement 2.5-liter EJ257 unit with the single-scroll VF48 turbocharger rated at 221 kW (300 PS) and 407 N·m (300 lb·ft) of torque. The turbocharger directs air through a larger top-mount intercooler which has lost the red “STI” that was on previous generations.
Like the standard WRX, the third generation model was shortened to “Subaru WRX STI”, with the Japanese markets notably abstaining from this convention. To differentiate the STI from the regular WRX, Subaru opted to manufacture the STI with a wider body and therefore track—as noted by the flared wheel arches. Furthermore, Subaru utilized aluminum suspension components for the STI. Electronic modifications include a multi-mode electronic stability control with “normal”, “traction”, and “off” modes; Subaru Intelligent-Drive (SI-Drive) with three modes: “intelligent”, “sport”, and “sport sharp”; and multi-mode driver controlled center differential (DCCD). The DCCD enables driver to switch between manual and automated torque distribution ratio of the center differential. This distribution can vary from 35/65 to 50/50 front/rear.

WRX STI R205
The R205 was a complete car from STI; the ‘R’ signifying the ‘road’. Based on the Impreza WRX STI, the model utilised technology developed through STI’s participation in the Nürburgring 24-hour Race to the full. As the name implies, focus was given to the car’s performance on public roads in its development in order to create the best road-going car possible. As for the engine, maximum output was increased to 320PS and the maximum torque to 44.0 kg-m by the introduction of such components as a special ball bearing twin scroll turbo. In addition, Brembo 18-inch discs and callipers were installed on the front and rear brakes. With regard to the exterior, aerodynamic devices including STI front and rear under spoilers were fitted. In order to further enhance the ‘flexible yet elegant driving feel’ that STI aims for, a newly developed Flexible Draw Stiffener was installed along with STI dampers/springs and Flexible Tower Bar. As a result, the car could achieve exceptional vehicle manoeuvrability, which made the car react smoothly to the driver’s intention.
