Subaru of America, Inc. introduced the 2018 WRX STI that offers performance, comfort, design and safety enhancements for a more rewarding driving experience. The new Subaru WRX STI is available at Subaru retailers from spring 2017.
A restyled front fascia of the Subaru WRX STI 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 that help illuminate curves in nighttime driving. For greater versatility, both WRX STI models now feature 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, which previously used a combination of mechanical and electronic center limited slip differential control, now uses electronic control for quicker and smoother response.
The 19-inch alloy wheels feature a striking Y-shaped spoke design and carry 245/35R19 tires that help raise cornering performance while giving the STI an even more aggressive stance.
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 305-hp 2.5-liter turbocharged BOXER engine, the WRX STI brings rally-bred performance technology to the road with Multi-Mode Driver Controlled Center Differential (DCCD) Symmetrical All-Wheel Drive. Standard handling technologies include Active Torque Vectoring and Multi-Mode Vehicle Dynamics Control.
Improved Usability with a Sporting Edge
The everyday usability that has contributed to Subaru WRX STI popularity gets even better for 2018. All models feature upgraded interior materials, rear seat armrest with cup holders, redesigned interior door grips and faster remote trunk opening.
New measures that reduce unwanted noise include thicker door glass, revised door sealing and a foam-filled windshield header beam.
A new, larger high-definition multi-function display (5.9-inch vs. 4.3-inch before) makes it easier to see vehicle functions at a glance. WRX STI models feature 8-way power driver’s seat. The STI comes standard with STARLINK 7.0″ multimedia audio unit which is upgraded from the previous STARLINK 6.2″ unit.
Subaru revised the front structure of the WRX STI for enhanced frontal collision performance. The WRX Limited, when equipped with EyeSight Driver Assist Technology now features Vehicle Hold (AVH), and a new EyeSight Assist Monitor (EAM). The EAM uses LED indicators to display EyeSight status and alerts on the windshield, allowing the driver to see them without diverting eyes from the road ahead.
The AVH feature replaces the Hill Holder and Hill Start Assist functions and offers greater functionality, holding the vehicle on all road grades, not only inclines. For example, AVH can help reduce driver fatigue by holding the car at traffic lights, and then can seamlessly transition to acceleration.
