MULTI-MODE DCCD (DRIVER CONTROLLED CENTRE DIFFERENTIAL)
Exclusive to the WRX STI, the multi-mode DCCD allows for the adjustment
of the electromechanical centre differential to ensure precise handling in
all conditions. Multiple modes can be selected depending on driving
conditions and driver preferences:
Auto: The default mode on start-up and the setting for all-around driving; torque distribution
automatically varies between 41/59 and 50/50 (front/rear) as conditions warrant.
[+] Auto: Enhances traction and stability on slippery roads by tightening the centre differential;
targets a 50/50 torque split, front/rear.
[-] Auto: Enhances turning capability and responsive handling for sportier driving by loosening
the centre differential; targets a 41/59 (front/rear) torque split.
Manual mode offers the driver a 6-step adjustment of the centre differential locking.

MULTI -MODE VEHICLE DYNAMICS CONTROL SYSTEM
For maximum flexibility, the WRX STI has three different Vehicle Dynamics
Control* system settings to choose from:

6-SPEED MANUAL TRANSMISSION
The short-throw, 6-speed manual transmission that comes
standard on the WRX STI is designed for outright shifting
speed, superb feel and bulletproof reliability. Tailor-made to
withstand the significant torque of the turbocharged SUBARU
BOXER engine and the superior traction of Subaru symmetrical
full-time AWD, this transmission is both crisp and responsive,
setting the stage for countless miles of sheer driving pleasure.

Normal mode provides the integrated safety and stability of Vehicle Dynamics Control,
Traction Control, and Super Sport ABS with Electronic Brake-force Distribution (EBD)
to provide the highest level of security.
Traction mode cancels the engine torque reduction traction control and delays the intervention
of Super Sport ABS and Vehicle Dynamics Control. With this mode, the driver maintains more
control over the performance of the vehicle.
Off mode cancels all other controls apart from Super Sport ABS and the Hill Holder system.
It is used mainly when attempting to drive out of a snowy or muddy situation or when the driver
insists on full control.
*The Subaru Vehicle Dynamics Control system may also be known as Electronic Stability Control.
