Subaru debuts the 2018 WRX STI with performance, comfort and safety upgrades. The restyled front fascia shows a sportier attitude, highlighted by a more aggressive front end with a larger lower grille opening. Both STI trims feature redesigned LED Steering Responsive Headlights and new roof rack mounting brackets.
A comprehensive handling enhancement for the 2018 STI includes the revised suspension tuning as featured on the WRX, plus a revised DCCD AWD system, significantly upgraded brakes and this model’s first-ever 19-inch wheels. The DCCD system now uses electronic control for quicker and smoother response.
The yellow-painted brake calipers identify a significantly upgraded Brembo Performance Brake System that now uses stronger monoblock 6-piston calipers in front, monoblock 2-piston calipers in the rear, and larger drilled rotors all around for better heat dissipation. New brake pads provide significantly greater surface area for improved braking feel and fade resistance. The STI also offers the Recaro seats (standard on STI Limited, optional for base trim).
Powered by a 305hp 2.5-litre turbocharged BOXER engine, the WRX STI brings rally-bred performance technology to the road with Multi-Mode Driver Controlled Centre Differential (DCCD) Symmetrical All-Wheel Drive. Standard handling technologies include Active Torque Vectoring and Multi-Mode Vehicle Dynamics Control.
As well as interior improvements, Subaru revised the front structure of the WRX STI for enhanced frontal collision performance. And the AVH feature replaces the Hill Holder and Hill Start Assist functions and offers greater functionality, holding the vehicle on all road grades.
