Subaru Impreza WRX STI A-Line Technical Data

Engine:

• 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.
  
• Tumble Generation Valve (TGV) controls the intake air stream to generate high combustion efficiency.

Drive train:

• SI-DRIVE (SUBARU Intelligent Drive), that enables the drivers to choose three different engine mappings, is standard.
  
• Paddle shift is featured to allow manual shifting without requiring the driver to release the steering wheel.
  
• Downshifting Blipping Control system was adopted. When down-shifting, the automatic transmission control unit interacts with the engine management system and increases engine revolutions instantly and to the exact required setting.
  
• Changing gears with the paddle shift can also be done by a temporary operation that does not require the selection lever to be set to the manual position.
  
• 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.
