The mainstream versions of the Subaru WRX that are sold in Japan will soon end production as orders close in May.
The WRX S4 and WRX S4 STI Sport are on the chopping block, reportedly due to noise and emissions regulations.
Does the end of these Japanese WRX models spell doom for their counterparts sold in the United States? Not exactly, but Subaru of America has nothing to say.
Subaru is shuffling things around with its WRX lineup in Japan. The automaker’s Japanese consumer website now notes that orders of the WRX S4—the sole version currently sold there—will shut down in May of this year. Also, the S4 STI Sport variant appears to be vanishing, as the site says it will be discontinued “with the current model.”
In case you needed some clarification: the S4 version of the WRX is best compared with the GT trim sold here. It exclusively comes with the CVT and a bevy of additional equipment. Outside of the recently announced WRX STI S# that is currently still listed as \”coming soon\” on the company’s website, this automatic version of the WRX is the only one sold in Japan. Our colleagues at Road & Track asked Subaru what the announcement means for our U.S.-market WRX, but a spokesperson said there’s no news to share.

The second WRX variant on the chopping block in Japan is the S4 STI Sport. This one is simply a trim variant of the WRX S4, so don’t worry too much about its disappearance. Subaru’s statement on its Japanese market consumer website follows below:
\”Regarding the current model, we will cease accepting new orders as of May 18, 2026, due to the end of production,\” the statement, first brought to broader attention by CarScoops, reads about the WRX S4. \”Furthermore, the WRX S4 STI Sport grade will be discontinued with the current model.\””
Subaru is making some significant changes to its WRX lineup in Japan, and the implications are raising eyebrows across the enthusiast community. The automaker has announced that orders for the standard WRX S4 in the Japanese market will conclude in May 2026. This move also signals the discontinuation of the WRX S4 STI Sport variant, leaving many wondering about the future of this iconic model, particularly for its U.S. counterpart. While there’s no immediate news for the American market, the reasons behind this shift in Japan offer valuable insights into the evolving landscape of performance vehicles.
The WRX S4, the primary version of the WRX offered in Japan, is slated for production end, with a final order date set for mid-May 2026. This comes as the WRX S4 STI Sport, a more performance-oriented trim, is also set to be discontinued with the current model generation. For those familiar with the WRX’s global variants, the S4 can be roughly compared to the GT trim available in the United States. Both models feature Subaru’s Lineartronic CVT (Continuously Variable Transmission) and come equipped with a comprehensive suite of standard features and performance enhancements.
Adding to the intrigue is the recently announced WRX STI S#, a limited-production model that is currently listed as \”coming soon\” on Subaru’s Japanese website. This special variant, which celebrates the brand’s rich rally heritage, is expected to be available in limited quantities, further highlighting Subaru’s commitment to performance enthusiasts even as it makes strategic adjustments to its mainstream offerings. However, outside of this exclusive model, the automatic WRX variants remain the only ones available in Japan.
The news has naturally led to speculation about the future of the WRX in the United States. When asked about the potential impact on U.S.-market WRX models, a Subaru of America spokesperson declined to comment, stating there was no news to share at this time. This lack of immediate clarification has fueled the ongoing discussion within the automotive press and among enthusiasts, as the WRX has long been a beloved model in the U.S., known for its rally-bred performance and practical sedan form factor.
The discontinuation of the WRX S4 and S4 STI Sport in Japan is reportedly linked to increasingly stringent noise and emissions regulations in the country. According to reports from Japanese market publications like Creative Trend, Subaru models equipped with the 2.4-liter turbocharged flat-four engine, the same powerplant found in the U.S. versions of the WRX, will face production halts due to these evolving standards. These regulations are becoming more comprehensive, encompassing not only tailpipe emissions but also real-world driving noise levels, which can be particularly challenging for performance-oriented vehicles with sporty exhaust systems.
These regulatory pressures are not unique to Subaru or the WRX. Many automakers are grappling with the need to adapt their lineups to meet stricter environmental standards while simultaneously maintaining the performance characteristics that define their brand identity. The trend toward electrification is accelerating, driven by regulatory mandates and growing consumer demand for sustainable transportation solutions. This shift is forcing manufacturers to reevaluate their product portfolios and make difficult decisions about which models to continue offering in different markets.
The implications of these Japanese market changes for the U.S. are multifaceted. While Subaru of America has not commented, it’s important to note that regulatory environments can vary significantly between countries. The U.S. market has its own set of emissions standards, which are also becoming more stringent but may not align perfectly with those in Japan. This divergence in regulatory frameworks can lead to different product strategies for the same model in different regions.
However, the fact that the WRX’s primary performance engine is facing regulatory challenges in Japan could eventually influence its availability in other markets. Automakers often optimize their production and development efforts around core platforms and powertrains. If a particular engine configuration becomes difficult or costly to certify for sale in major markets like Japan, it could impact its long-term viability across the entire global lineup. This doesn’t necessarily mean the WRX will disappear from the U.S., but it could lead to changes in its specification or the introduction of new technologies to meet evolving standards.
Looking ahead, there are some indications of what might come next for the WRX in Japan. Reports suggest that orders for new WRX trims will resume next year, possibly with a manual transmission option. This potential return of a manual transmission in the Japanese market would be a significant development, as the current S4 model is exclusively offered with a CVT. For performance enthusiasts, the availability of a manual transmission is often seen as a more engaging and connected driving experience, and its reintroduction would be welcomed by many.
The timing of this potential reintroduction is notable. It suggests that Subaru may be developing updated versions of the WRX that can meet the latest regulatory requirements while still delivering the performance and driving dynamics that enthusiasts expect. This could involve powertrain refinements, the integration of new emissions control technologies, or even a re-evaluation of the model’s overall configuration to optimize for both performance and compliance.
For the U.S. market, the possibility of a future WRX with a manual transmission is particularly exciting. While the current WRX is available with a manual transmission in the U.S., the success of the CVT-equipped GT trim has led some to question the long-term commitment to manual transmission offerings. A renewed emphasis on manual transmission availability, potentially in combination with other performance updates, could revitalize the WRX’s appeal to traditional enthusiasts while also attracting new buyers who appreciate the engagement of a driver-focused car.
It’s also worth considering the broader context of Subaru’s electrification strategy. The company has announced plans to introduce new electric vehicles, including the Trailseeker, which is already being produced at the same facility as the WRX in Japan. This investment in EV technology signals a long-term commitment to sustainable mobility, and it’s likely that electrification will play an increasingly important role in Subaru’s future product portfolio. However, this doesn’t necessarily mean the end of internal combustion engine (ICE) performance models.
Many automakers are adopting a multi-powertrain approach, offering a range of propulsion options to cater to different market needs and consumer preferences. This strategy allows manufacturers to balance their sustainability goals with the demand for traditional ICE vehicles, particularly in segments like performance sedans where enthusiasts often have strong preferences. Subaru’s future lineup could very well include both electrified and ICE performance models, providing buyers with choices that align with their driving priorities and environmental concerns.
The limited-production WRX STI S# mentioned earlier is a testament to Subaru’s continued commitment to its performance heritage. With only 600 units planned for production, this special variant represents a celebration of the brand’s rally roots and is expected to be highly sought after by collectors and enthusiasts. Even as Subaru adapts to evolving market conditions, it’s clear that the company values its performance identity and is willing to invest in limited-run models that cater to its most passionate customers.
The implications of the Japanese market changes extend beyond the WRX itself. They reflect broader industry trends that are reshaping the automotive landscape. Regulatory pressures are forcing automakers to innovate and adapt, leading to the development of new technologies and powertrain configurations. Consumer preferences are also evolving, with growing demand for sustainable transportation options and connected in-car experiences.
In this dynamic environment, automakers must strike a delicate balance
