Tested: Subaru’s 2025 WRX tS Inches Toward the Top Michael Simari – Car and Driver
1/16/25 UPDATE: This review has been updated with instrumented test results.
It’s said that great things come to those who wait. Just like many of you, we’ve been patiently waiting for Subaru to roll out the fifth-generation WRX STI. Well, we might be twiddling our thumbs forever, as Subie has yet to reveal any plans for the big-power, tall-wing, variable-center-differential rally king (the recently announced WRX STI S210 prototype isn’t quite there, if it even comes to the U.S.). As a consolation, Subaru has thrown the GT and TR models into the blender and poured a 2025 Subaru WRX tS.
The Mix
For the first time, the tS (which stands for “tuned by STI”) badge is applied to the all-wheel-drive WRX. To arrive here, Subaru equips the tS with the WRX TR’s meaty Brembo brakes, which feature six-piston calipers in the front and two-piston binders in the back. The only difference is that the tS calipers are painted gold, whereas the TR’s are red. They squeeze cross-drilled rotors measuring 13.4 inches in the front and 12.8 inches in the rear. Also shared are the 19-inch Bridgestone Potenza S007 summer tires.

From the WRX GT comes a choice of five drive profiles: Comfort, Normal, Sport, Sport+, and Individual. There are also three steering modes (Comfort, Normal, and Sport), as well as the ability to adjust the powertrain from Normal to Sport, where the most aggressive setting speeds up the interaction between the accelerator and the throttle plate. Most important, the tS receives the GT’s adaptive dampers, which STI has calibrated for the tS specifically for roads in the United States. They also have three positions of adjustment (Comfort, Normal, and Sport), are tuned to be slightly stiffer than the GT’s, and provide a claimed 30 percent reduction in roll and 55 percent reduction in pitch compared with the TR’s passive dampers. Thankfully, the GT’s mandatory continuously variable automatic transmission isn’t on the menu; the tS is offered only with a six-speed manual.
Inside, other fixings specifically for the tS include a 12.3-inch digital instrument cluster; bright blue accents scattered throughout the interior, including on the body-hugging Recaro seats; and STI logos on the start button and gauges, making it look like you’re in an actual STI. To preserve space for helmets—and possibly to counter the minor additional weight of the big brakes—there’s no sunroof option. On the exterior, the tS can be identified by the aforementioned wheels, black mirror caps, a shark-fin antenna, and a lip spoiler on the trunklid. There are also some pink badges on its rear end.

Track Time
We initially sampled the tS at California’s Sonoma Raceway. It took only a handful of laps to conclude that the 271-hp turbocharged 2.4-liter flat-four could stand another 50 or 70 ponies. All of this Subie’s competitors—the Honda Civic Type R, the Volkswagen Golf R, the Toyota GR Corolla, and the Hyundai Elantra N—make more horsepower. Across the start/finish line in fourth gear with the accelerator to the floor, the tS huffs and puffs its way up the hill into Turn 1. In fact, its straight-line speed slightly lags that of the WRX Limited, which in our testing hit 60 mph in 5.5 seconds and cleared the quarter-mile in 13.9 seconds at 101 mph. The tS required 5.6 seconds to reach 60 mph and dispatched the quarter-mile in 14.0 seconds at 99 mph. By 130 mph, the standard-issue WRX has a two-second lead on the tS, 26.4 to 28.4 seconds. Which doesn’t sound like much, but it represents more than a football field in distance at that speed. All else being equal in terms of power and weight, we’d blame the tS’s big wheels and chunkier rotors for dulling the acceleration.
With the dampers set to Sport, body roll stays in check, even off Sonoma’s massive candy-cane curbing at the top of the hill. There’s more audible feedback from the Bridgestones than through the steering wheel when the front-end grip gives away, but the steering effort in the heftiest mode is appreciated. The tS has a brake-based torque-vectoring system, and you can feel it helping the car rotate midcorner. The tS does edge the standard WRX in roadholding, managing 0.96 g to the Limited’s 0.95 g.

The Brembo brakes are the star of the package, but our testing revealed a confounding result that was confirmed by a WRX TR that we sampled with the identical brake-and-tire package. Namely, the lesser WRX Limited stops shorter—at least, in a panic-braking situation. The tS stopped from 70 mph in 159 feet and needed 319 feet to stop from 100 mph, while the Limited required only 153 and 317 feet from those speeds. Clearly, the standard WRX’s brakes are really good.
But track work is where the Brembos really shine. Lap after lap, we became more confident and drove deeper into the brake zones. The pedal feel never wavered, retaining its firm disposition during hard use. The Brembos’ real test will arrive once we get this car to Virginia International Raceway for Lightning Lap.

Street Work
Outside racetrack land and on the hillsides looking into Napa Valley, the Subie’s Comfort setting for the dampers is the sweet spot. The electronically controlled units gracefully absorb lumpy tarmac better than in the Sport setting, which suffers stiff and jarring impacts. The steering effort in the lightest setting is too effortless, so stick with Sport for the best experience. The short gearing means you might be all over the shifter like you’re gut-punching Mike Tyson, but we’ll gladly take a right-arm workout over any CVT encounter.
When you’re not hustling the tS, you can better take in the new digital gauge cluster. Its normal mode, a standard tachometer and speedometer display, is ideal for track use. The navigation mode crisply renders a map, and when Apple CarPlay is active, Apple Maps are displayed. The EyeSight mode focuses on the plethora of driver-assist systems, which Subaru began offering on manual-gearbox cars for 2024.

The WRX tS’s price checks in at $46,875, the same amount Subaru charges for the GT. While we’d rather have the tS’s performance hardware than the GT’s luxury accouterments, we’ve still got our fingers crossed for the greatness of a full STI model.
