FHI to introduce a New Additional Model in the Subaru Impreza WRX STI: A-Line

Tokyo, February 24, 2009 - Fuji Heavy Industries Ltd. (FHI), the maker of Subaru automobiles, today launches “Subaru Impreza WRX A-Line” which is a new addition to the current WRX STI model. The model goes on sale nationwide through Subaru dealerships today in Japan .

Based on the Impreza WRX STI, the WRX STI A-Line model was developed to offer its distinctive driving performance to a wider range of customers by integrating 2.5-litre turbocharged Boxer engine and 5 Speed Automatic Transmission with SPORTSHIFT*.

In addition, the current WRX STI was given some refinements to enhance comfort and quality feel; 8 way power adjustable front seats and a new body color, “Satin White Pearl”, is now available.

The model features the exclusively developed 2.5-litre Subaru BOXER turbo engine with SPORTSHIFT* E-5AT, while retaining the basic component such as chassis and body of the WRX STI, Subaru's performance flagship.


- The unique 2.5-litre BOXER engine comes with a single scroll turbocharger and produces a flat torque from the low and mid-rev range to high-rev range.
- Dual Active Valve Control System (AVCS) was adopted to control continuously valve timing on both intake and exhaust valves, which improves low and mid-range range torque, high-rev range output and environmental friendliness.

Drive train:

- SI-DRIVE ( SUBARU Intelligent Drive ), that enables the drivers to choose three different engine mappings, is standard.

- VTD (Variable Torque Distribution)-AWD system was adopted to provide excellent stability of the vehicle, which controls the torque distribution ratio between the front and rear axles depending on driving conditions.
