TheSubaru WRX STI is a variant of theSubaru WRX sedan produced by in-house tuning companySubaru Tecnica International between 2014 and 2021. It succeeded theSubaru Impreza WRX STI. Production of the WRX STI concluded after its first generation, there are currently no plans for aVB WRX STI.[1] STI also offers many factory-backed accessories usually available from dealerships, and accented in STI's signature cherry blossom, a tribute to the iconictree of the same name from the brand's homeland of Japan.
The VA WRX STI was released in 2014 alongside the VA WRX. It featured uprated brakes, the famous Subaru Technica International tuned EJ257 4-cylinder engine, an uprated 6 speed manual transmission, along with a unique body kit and spoiler. Interior upgrades include an STI-exclusive gauge cluster, shifter knob, and other unique touches, including Recaro bucket seats in certain models. The WRX STI for the most part featured a red accented interior, over the WRX's black and grey.[2]
Starting with the MY2018 update, the WRX STI obtained several changes, such as a restyled front fascia, steering responsive headlights (SRH), revised suspension tuning, a fully electronic driver controlled central differential (DCCD), 19-inch wheels, and upgraded Brembo brakes.[3]
In 2020, Subaru announced they would be phasing out the WRX STI along with the EJ257, the last variant of theEJ engine, with the release of the VB series WRX in 2021. Subaru introduced the STI WRX EJ25 Final Edition, based on Subaru's flagship STI Spec R. The EJ25 Final Edition features a range of upgrades including BBS 19” gold forged aluminium wheels, silver Brembo calipers, black door mirror covers, front grille pinstripe in STI cherry blossom, Final Edition engine cover plate, and numbered EJ25 Final Edition badge.[4] Only 75 were produced for markets across the globe.
Although there is no official VB WRX STI available, Subaru has showcased an STI S210 prototype,[5] though limited to Japan only. For markets outside of Japan, Subaru has introduced several trim levels of WRX with 'tuning by STI'[6] and STI offers many accessories for the second generation WRX such as lip spoilers, exhaust tips, shifter knobs, and many other options depending on region.
On June 1st, 2025, Subaru's CTO (Chief Technology Officer) Tetsuro Fujinuki announced that the company will unveil a new car at the Japan Mobility Show that will be held in October 2025. A drawing of a car was quickly shown to the audience and the styling of the featured drawing has auto journalists speculating that it could be of the new generation WRX STI.[7][8]
