What's New
The 2021 Subaru WRX STI rolls over with few changes. Keyless access and push-button start are now standard, but otherwise Subaru’s rally-inspired racer stays the same.
The WRX STI is nearing the end of its model lifespan, and we expect a redesign within the next year or two. It competes with budget-friendly performers like the Volkswagen GTI and Honda Civic Type R.
Choosing Your Subaru WRX STI
The WRX STI comes in only two trims: base and Limited. Prices start at $38,170 for base models, while the Limited is an extra $4,700.
Engine Choices
Both versions of the WRX STI use the same powerplant. The 2.5-liter turbocharged engine makes 310 horsepower and 290 pound-feet of torque. Those are strong numbers that compare well to the competition: the Civic Type R makes 306 horsepower, and the GTI must make do with 228.
The WRX STI is unapologetically a car for purists, and a six-speed manual transmission is the only option. All-wheel drive comes standard.
Passenger and Cargo Capacity
The WRX STI seats five passengers. Cabin space is reasonable for a car this size — rear leg room checks in at 35.4 inches, which is average for the class.
Trunk capacity is an even 12 cubic feet. That’s decent for a compact sedan, but it suffers by comparison to hatchback rivals.
Safety Features
The WRX STI may like to go fast, but it hasn’t forgotten safety. Crash test results are favorable, and the IIHS bestowed a Top Safety Pick award. The manual transmission prohibits features like automatic emergency braking, but blind-spot monitors come standard on the Limited trim.
Connectivity
Both trims use the same seven-inch infotainment touchscreen. The system is compatible with either Apple CarPlay or Android Auto. There are two USB port for front passengers, and another 5.9-inch screen atop the dash shows vehicle information. The Limited trim adds navigation and Harman Kardon sound.
The base WRX STI may be the cheapest way into the lineup, but it’s still relatively expensive for a Subaru. It comes with a kit of features to match.
The front seats are heated, and the flat-bottom steering wheel is wrapped in leather. Dual-zone automatic climate control and push-button start come standard. To complement its powerful engine, the base model comes with Brembo brakes and a stiff sport-tuned suspension.
8-way power adjustable Recaro bucket seats are available for $2,250. Otherwise, customization options are limited.
The Limited trim adds a dose of luxury to the STI’s performance. Recaro seats are standard and upholstered in leather. Also included are a power moonroof, a Harman Kardon sound system, and blind-spot monitors.
Buyers can swap the STI’s conspicuous wing for a lip spoiler as a no-cost option. Otherwise, little is left to add.
Compare WRX STI Trims Side-By-Side
Performance is the main allure of the WRX STI, and it’s the same between the two trims. As a result, we’d recommend sticking to the base model for best value unless you're looking to save money by opting for the standard Subaru WRX.
