Subaru Forester Turbo 2.5 Litre Unveiled | Part Three

Symmetrical AWD Transmission - More Intelligent Than Ever

Subaru’s rally-honed symmetrical all-wheel drive transmission reduces drive friction, fuel consumption and power loss because:

  • The short ‘boxer’ engine is in-line with the transmission
  • The low engine height allows the front drive-shafts to be almost horizontal
  • Power to the rear wheels is in a straight line via a prop shaft rather than via an awkward transfer ’box
  • The light and compact AWD system can be installed in the transmission case
  • The perfectly symmetrical AWD system allows chassis engineers to tune the suspension for excellent handling and roadholding
The new Forester’s quick-thinking full-time AWD system on manual models splits power 50/50 front to rear which gives enhanced straight-line tracking and extra agility through corners.

However, as soon as slip is detected, the centre differential with its viscous-coupling distributes torque to the axle with the most grip. This happens in milliseconds.

All the driver is aware of is less understeer/oversteer than expected and reassuring grip where a 2WD car would be sliding.

Low Centre Of Gravity

Fundamental to the latest Forester - launched in October 2002 - is the low centre of gravity afforded by its all-alloy horizontally-opposed engine and Impreza-based chassis with long-travel all independent suspension.

This low centre of gravity means the Forester can offer a similar high seating position and ground clearance to a conventional SUV but with outstanding handling and active safety.

Coupled with Subaru’s AWD transmission - and standard rear limited-slip differential - the Forester offers tremendous off-road grip and on-road stability.
