Vehicle Dynamics Control System
Every WRX comes standard with Vehicle Dynamics Control (VDC). The WRX STI takes it further with three selectable modes1 to
offer flexible performance for changing driving conditions. Normal mode fully engages VDC, traction control and the Antilock
Braking System (ABS) for maximum response to detect loss of control. Traction mode raises the intervention threshold of the VDC
and traction control systems, maximizing torque delivered to the wheels. Off mode completely deactivates VDC.

Multi-mode DCCD (Driver Controlled Centre Differential) 2
For more added control, the WRX STI DCCD’s manual mode and three automatic modes allow you to dial in two types of centre
differential locking for ideal traction and agility on any road surface. Starting with a 41/59% front/rear torque split, DCCD adjusts
both an electromagnetic multi-plate transfer clutch and mechanical locking of a Limited Slip Differential (LSD) to apportion the
torque to the front and rear wheels.
1 Multi-Mode functionality only available on WRX STI.
2 Only available on WRX STI.

Performance Chassis and Suspension
The pursuit of performance perfection never ends for Subaru. That’s why the
Subaru WRX and WRX STI feature design enhancements that intensify their
handling prowess. Utilizing the Dynamic Chassis Control Concept (DC 3), all the
design elements of the WRX and WRX STI — from their rigid frame geometry
to Symmetrical AWD, which provides fierce traction while helping balance the
chassis — work together to create precise steering and dynamic cornering. They
also feature a suspension designed for a greater connection between driver
and vehicle. After extensive testing, the suspension of the WRX and WRX STI
is stiffer and tuned for greater precision. It features lower control arms with
pillow ball bushings 2, which increase stability, maximize tire contact and reduce
understeer during cornering. What’s more, the WRX STI is lower for tight
cornering and immediate steering response. With these suspension setups,
the WRX and WRX STI give you intuitive feedback and control that make driving
pure inspiration.

SI-DRIVE (Subaru Intelligent Drive)
SI-DRIVE lets you adapt the driving character of the WRX
STI to your liking. Put it in Intelligent mode for smooth
power and optimal ef ficiency. Selec t Spor t mode for
versatile command of every condition. To extract the
maximum response from the turbocharged engine,
switch to Sport Sharp mode. It gives you the most direct
throt tle response and precise rev control across the
entire rpm range.
