The 2021 Subaru WRX STI holds a special place in my heart as the last internal combustion engine powered by an EJ257 engine. It’s a bit surprising to learn that the 2022+ WRX won’t have an STI version in the U.S., and Subaru plans to reintroduce the STI in some EV form in 2028. As a car enthusiast and weekend road warrior, this shift towards electrification feels like a loss. Devotees of the STI brand are acquainted with the captivating legacy encompassing Subaru’s rally history, iconic figures like Bunta from Initial D, and the beloved Subaru Impreza WRX STi GC8 or 22B.
When I got wind of the fact that they were discontinuing the STI and that the 2021 model would be the last, I knew I had to get my hands on one. Unfortunately, by the time I started searching, the new ones were no longer available at the Subaru dealer. However, I lucked out and managed to find a low-mileage 2021 model with around 7500 miles.
The last true Subaru WRX STI
Driving the Subaru WRX STI is a unique experience, with its mandatory manual transmission, rally-bred all-wheel-drive system, and an overall exhilarating feel. It’s the mightiest and most aggressive WRX, but it comes with its quirks – it’s the noisiest, stiffest-riding, and rawest version in the lineup. Inspired by Subaru’s factory-backed FIA World Championship Rally series race cars, this car is designed for maximum performance.
For the 2021 model, there are minimal changes, but the base version now includes passive hands-free entry and push-button start. The pricing ranges from $38,170 for the base model to $42,870 for the Limited trim. The Subaru WRX STI Limited trim provides identical standard performance features as the base model, accompanied by extra amenities such as heated Recaro branded seats, STI aero styling, and a sunroof.
Powering the WRX STI is a turbocharged 2.5-liter flat-four engine, delivering a characteristic flat-four burble. It’s not as smooth or hard-hitting as some of its competitors, and the engine’s initial lag and punchy power delivery can be a bit challenging for city driving. But when driven with enthusiasm, the STI’s controls synchronize effectively, providing an athletic and enjoyable experience on twisty roads.
In terms of fuel economy, the WRX STI falls behind, with an EPA estimate of 16 mpg in the city and 22 mpg on the highway. The interior has a basic feel, despite some red accents and optional Recaro seats. Cargo space is reasonable for a sedan, although hatchback competitors offer greater versatility.
This 2021 STI is the ultimate consumer-accessible version, drawing inspiration from two renowned predecessors – the Type RA and the s209. Inheriting key features and learnings, such as a forged short block and suspension modifications from the s209, this final version encapsulates the best of the best from its predecessors.
2018 WRX STI Type RA
The RA designation stands for “Record Attempt” and reflecting Subaru’s relentless pursuit of performance excellence. Back in 1989, the RA legacy began when a competition Subaru Legacy broke the FIA World Speed Endurance Record, covering over 62,000 miles in just 18 days and reaching a top speed of 138 mph. Now, the spirit of endeavor continues with the upcoming Nürburgring speed record attempt by the special race model, the WRX STI Type RA NBR Special.
As for the 2018 Subaru WRX STI Type RA, it’s not just a car – it’s a performance masterpiece. This limited edition model brings increased performance through thoughtful weight reduction, suspension upgrades, and enhancements to the 2.5-liter turbocharged BOXER engine. Features like the carbon fiber roof panel, removal of the spare tire, carbon fiber pedestal wing, and lightweight BBS 19-in. forged alloy wheels make it stand out.
Under the hood, the Subaru WRX STI Type RA boasts an estimated 310hp, thanks to an STI-specified cold air intake, high-flow performance exhaust, retuned ECU, and stronger pistons. The six-speed transmission with a revised 3rd gear ratio and short throw shifter ensures exhilarating acceleration.
Handling is top-notch with inverted front struts, rear double wishbone suspension, and a modified multi-mode VDC for enhanced stability control. The Brembo brake system guarantees impressive stopping power.
Visually, the Subaru WRX STI Type RA is a showstopper, with exclusive Cherry Blossom Red accents and a captivating exterior design. Inside, the Recaro® performance design front seats, red stitching, and Ultrasuede® wrapped steering wheel create a sporty and luxurious atmosphere. Each of the 500 produced WRX STI Type RA models is individually numbered, making it a unique and exclusive piece of automotive excellence – just for you.
2019 STI s209
In 2019, Subaru Tecnica International (STI) unleashed the STI S209, marking its most powerful model exclusively crafted for the U.S. market. As the first S-line STI product in the U.S., this limited-edition vehicle, with only 209 units available, embodies upgrades in power, handling, aerodynamics, and driver engagement. The heart of the S209 is its reworked 341-horsepower 2.5-liter SUBARU BOXER engine, featuring an STI turbocharger by HKS®. The exterior boasts a wide-body treatment, wide fenders, and a distinctive look, with available colors in WR Blue Pearl and Crystal White Pearl. You may notice similarities to the Type RA, and that is by intent.
Designed for high-performance driving, the S209 draws inspiration from STI’s track prowess, particularly the WRX STI Nürburgring Challenge racecar. Its exterior enhancements include wide fenders, front canards, and a rear wing for improved aerodynamics. Underneath, specially developed Bilstein® dampers, coil springs, and a reinforced chassis contribute to an exhilarating driving experience. The legendary EJ25 engine propels the S209 with increased horsepower and midrange torque.
The S209 offers a close-ratio 6-speed manual transmission, Subaru Symmetrical All-Wheel Drive, and advanced features like Driver Controlled Center Differential (DCCD) and Active Torque Vectoring. The SI-Drive system provides three modes for varied driving experiences.
Performance-focused details extend to the high-flow intake system, intercooler water spray system, and an STI-tuned engine control module. Limited production details, such as special badging and silver stitching on the steering wheel and console, emphasize the exclusivity of the S209. With only 209 units available, each bearing a unique serial number, the STI S209 stands as a pinnacle of Subaru performance and craftsmanship.
Closing Thoughts
What captivates me about the S209 is its deliberate craftsmanship, meticulously tuned for precision on U.S. roads. As the ultimate showstopper from the STI organization and with a limited production, it reflects a genuine labor of love. Boasting 341 horsepower, it stands as the fastest STI to date, surpassing the 2021 STI at 310hp. The aggressive styling, featuring a black race wing and wide body flares, adds to its allure. Personally, I’m drawn to the distinctive rims from BBS. The behind-the-scenes glimpse into the making of the S209 through a 2-part YouTube video from the STI group adds an extra layer of appreciation.
While I could not get my hands on the S209 which is priced upwards of $90,000-$110,000 (in 2024) due to appreciation, the 2021 Subaru WRX STI is a special car for enthusiasts like me, offering thrilling performance and unique features. However, its outdated engine, noise, and lower fuel efficiency compared to rivals might be a deal-breaker for some, but for me, it’s a testament to JDM rally history and the best car I’ve seen.
