2018 Subaru WRX STI Limited
The world rally-inspired sedans received a ground-up redesign for 2015, featuring much more distinctive bodywork all around including unique bumpers, fenders, aero, and trim details when compared to its Impreza sedan donor model, plus a new, more potent direct-injected 2.0-liter turbo-four replacing the aged sequential multiport injected 2.5 in the regular WRX, this new engine adding three horsepower and 14 more lb-ft of torque resulting in 268 horsepower and 258 lb-ft, a six-speed manual in place of that model’s old five-speed, and the option of a sport-tuned continuously variable transmission (CVT) with paddles where no automatic was ever offered before. The STI continued forward with its 2.5-liter turbocharged flat four making 305 horsepower and 290 lb-ft of torque.
Model year 2016 added one-touch turn signals, revised steering wheel controls, and a standard 6.2-inch touchscreen with StarLink smartphone integration, plus the Hyper Blue-painted STI Hikari limited edition; 2017 added automatic reverse-tilt to the passenger’s side power mirror, a more premium-like woven fabric headliner, and improved the six-speed manual transmission’s feel, while Limited trims also received Siri Eyes-Free, Mirror Link, Travel Link and SiriusXM Traffic integration; and now for 2018 this dynamic duo get a few styling updates, some chassis mods, a bevy of additional refinements, as well as new safety features, while the STI gets one redesigned drivetrain component. Subaru has made changes to the 2019 version too, but I’ll leave those until later.
The 2018 styling updates affect both models and include a new front grille and bumper design and reworked interior door trim, while other updates include a new primary gauge cluster with a 5.9-inch color multi-information display (MID), a fold-down rear center armrest with integrated cupholders, reduced interior noise, new suspension tuning, and bigger batteries.
Specific to the base WRX, manual models get a new shift lever and yet better shift and clutch take-up feel, plus improved steering feel, whereas the STI now includes standard LED headlights, standard cross-drilled Brembo brakes that are 24 mm larger and 6 mm thicker up front than those on the regular WRX, at 340 by 30 mm, plus 40 mm larger and twice as thick in back at 326 by 20 mm, with six-piston front calipers (two more than the previous STI and four more than the regular WRX) and two-piston rear calipers (double what the WRX offers) plus four-channel, four-sensor and g-load sensor equipped Super Sport ABS, a revised Driver’s Control Center Differential (DCCD) system that’s no longer hybrid mechanical with electronic center limited-slip differential control, but rather an electric design that provides quicker, smoother operation, while inside it gets red seatbelts.
As for new 2018 options, Sport trim with the base WRX is updated to include steering-responsive LED headlights, LED fog lights, and a 10-way powered driver’s seat, while the Performance package adds new StarLink connectivity apps including Yelp, Best Parking and Glympse. Additionally, Performance packaged models with the manual now get eight-way powered front seats, leather and ultrasuede upholstery, proximity keyless access with pushbutton ignition, navigation, a Harman Kardon audio upgrade, and blindspot detection with rear cross-traffic alert, while Premium and Limited trimmed cars with the Sport Lineartronic CVT become the first WRX models to ever have the option of Subaru’s EyeSight suite of advanced driver assistance systems.
As for the STI, 19-inch wheels are now standard, as are wiper-activated automatic headlights, while the fog lamps were deleted to allow for larger air intakes. Additionally, STI models upgraded to Limited trim can be had with either a massive rear wing or much smaller lip spoiler, the latter more appealing to those who don’t want to draw as much attention from passersby, while a set of Recaro sport seats are added in both leather and ultrasuede upholstery, with the driver’s receiving eight-way powered adjustment. Subaru also includes the aforementioned StarLink apps with the Limited upgrade. Like I said, Subaru doesn’t exactly remain idle with the WRX and STI, despite its relative niche model status.
Then again, if Subaru has a flagship model it would have to be its WRX STI. Certainly the new Ascent crossover SUV is larger and more luxurious, as is the mid-size Outback crossover and the Legacy sedan it’s based upon, such attributes normally befitting of flagship status, but the WRX STI has become legendary for being one of the best performing sport compacts available since inception, and as noted earlier, is derived from the brand’s motorsport heritage.
I like the styling updates, as they give the front end a more aggressive appearance that strengthens the entire design. I also lean more toward subtlety than flash, so therefore I was glad Subaru chose the smaller lip spoiler for my ride. Of course I appreciate the downforce benefits of a gargantuan rear wing when attempting to breach the sound barrier, or at least reach the STI’s top track speed of 156 mph, but there’s no race course anywhere near my home that would allow for such a test, and it goes without saying that I’d rather not have my car impounded before being forced to pay the towing and storage fees, plus the fines that would be due after being caught doing speed trials on public roads, and then have to explain to Subaru why they couldn’t access their car for a week or more. Nah, I’d go for clean lines over radical aero any day of the week, and this upgraded STI looks much more appealing from front to back.
Subaru follows the usual red on black performance car interior theme, and while I won’t go so far to call this approach creative, the overall look is well executed, meaning that it’s not as gauche as some others, such as Honda’s Civic Type-R (that goes for exterior styling too). My tester’s Limited trim meant that psuede covered the door panel insets, armrests, and center seat panels front to back, while the ones up front had the “STI” initials embossed into the leather headrests and white “RECARO” lettering embroidered into the top portion of the seat panel. The side bolsters are covered in mostly black leather other than their top portions finished in a thick stripe of red, while the outer sections receive a thin line of red contrast stitching. Subaru decorates the seatbacks further with red piping up top, but really what matters most is how wonderfully comfortable and incredibly supportive they are.
The rear seats aren’t quite as fancy, but they’re surprisingly dressed up with the same red and black, partial-psuede and leather upholstery, plus the outboard positions are cut out like buckets so even those in back have some lateral support to keep them in place if you plan on having some fun.
On that note, adjustability is critical in a performance car, because along with the lateral support factor you need to maintain as much control as possible. To this end the upgraded seats include the aforementioned power adjustments, while all STI trims provide plenty of telescopic reach from the steering column resulting in a rally-ready driving position, or at least the ability to get the seatback upright and steering wheel as close to the driver as possible.
The STI steering wheel is thick, padded, flat-bottomed, leather-wrapped and ideally formed for comfort and, once again, control, with red baseball stitching along the inside of the rim, while the shift knob is black leather as well, with a bright red translucent candy drop top. The leather boot below gets red stitching to match the same thread used on both sides of the padded leatherette trimmed center console, the new STI a lot more luxe than any previous WRX model.
The hood shielding the dash-top MID gets the same red-stitched leatherette treatment, while the fiery color illuminates the primary gauges, the infotainment interface background and some of the cabin’s switchgear before continuing onto each door panel and elsewhere throughout the interior. And as overdone as this might sound in words, it’s actually quite tasteful when viewed.
That gauge cluster is 100-percent purposeful performance, with bright, clear dials that are easy to read in any light, while the multi-info display at center isn’t as graphically stimulating as some others in the segment, yet still displays an eco-gauge, driving time info, a digital speedometer, a gear display, cruise control details, an odometer, trip meter, SI-Drive (Subaru Intelligent Drive) indicators, and something no other brand’s vehicles have, a graphic showing front and real power bias from the aforementioned DCCD system, actuated via a rocker switch on the center console.
Just in case you’re feeling shortchanged for not getting as much digitized imagery in the gauge cluster display, check out the big dash-top MID mentioned a moment ago. Controlled via a rocker switch just above the infotainment display, it comes filled with a high-resolution TFT screen and loads of functions like average fuel economy, graphics for the configurable center differential, a digital PSI boost gauge, etcetera, making it a helpful sidekick to the much larger StarLink infotainment touchscreen on the center stack below, this such a massive improvement over previous WRX systems that it’s a night and day experience.
Thanks to its Limited trim upgrade, my tester’s touchscreen was a half-inch larger at 7.0 inches in diameter, while its ultra high-resolution glossy display also gets navigation with detailed mapping, plus Apple CarPlay and Android Auto, along with all the functionality of the lesser 6.5-inch system, such as a backup camera with guidelines, and all of the aforementioned features and apps. They’re all accessible from an interface with superb graphics and a really nice layout, featuring big digital buttons for the map, audio, phone, apps, info, and settings interfaces.
A high-quality dual-zone auto climate control system sits below, with really well made knobs that don’t wiggle when rotated, plus nice, tight fitting buttons. I also like that the HVAC system’s temperature readouts are displayed up on the dash-top multi-info system for easy visibility when on the move, just another way Subaru keeps things convenient and safe.
Over and above features already mentioned, $41,395 Limited trim includes proximity keyless access with pushbutton ignition, and a great sounding 320-watt, nine-speaker Harman Kardon audio system, while additional items pulled from $36,595 the base STI include 245/35R19 89W Yokohama Advan Sport V105 performance rubber to go with those aforementioned uprated rims, a glossy black grille, welcome lighting, brushed aluminum doorsills with STI branding, carpeted floor mats with a red embroidered STI logo, a leather-wrapped handbrake lever, front and rear seats upholstered in black and red leather with black ultrasuede inserts, dual-zone auto climate control, a powered moonroof, the Subaru Rear/Side Vehicle Detection System (SRVD) featuring blindspot detection, lane change assist, and rear cross traffic alert, and a bevy of performance upgrades including a quick-ratio rack and pinion steering system, inverted KYB front MacPherson struts with forged aluminum lower suspension arms, performance suspension tuning, high-strength solid rubber engine mounts, a red powder-coated intake manifold, a close ratio six-speed manual gearbox, a Helical-type limited-slip front differential and a Torsen limited-slip rear diff, plus more.
I should also point out that Subaru finishes the interior off with a higher level of soft-touch synthetic surface treatments than ever before, getting the car closer and closer to premium territory with each passing generation. And it’s plenty roomy for a compact too, both up front and in back where the seats are nicely sculpted out to keep your rear passengers in place when pushing the envelope. Now that we’re contemplating such practical matters, the STI’s trunk is plenty large for a sports car at 12 cubic feet, and it benefits from expansion for longer items via 60/40-split rear seatbacks.
Along that vein, the fact that you’re driving a turbocharged four-cylinder powered compact car won’t benefit your pocketbook all that much in the STI, thanks to 17 mpg city, 22 highway and 19 combined. If that’s an issue for you the regular WRX is good for a claimed 21 city, 27 highway and 23 combined, while the same model with its CVT can eke out 18, 24 and 21 respectively.
By the way, the SI-Drive system noted earlier lets you choose between the default Intelligent driving mode, Sport mode and Sport-sharp mode, which is Subaru-speak for the usual comfort, sport and sport-plus modes. They work wonders, especially the latter “S#” mode, which sharpens up the STI’s responses to the point of racetrack readiness, ideal for those moments when you want to get the most out of a very potent package.
This is where the STI’s 2.5-liter EJ257 H4 comes in, an engine that hasn’t changed one iota since before this car’s full redesign. Therefore its output remains 305 horsepower and 290 lb-ft of torque, while its six-speed gearbox is truly smoother to operate since its multiple refinements. Lastly, the WRX STI’s torque-vectoring Symmetrical-AWD system is still among the best in the business, designed for all surface traction, meaning it can easily manage wet or dry pavement, snow, gravel, dirt, or almost anything else you throw in its way.
I kept it to dry tarmac during my test, and no I didn’t have a track at my beck and call so I obeyed all posted speed limits and… ha ha yeah right. Of course, I found opportunity to open it up when the road cleared and it was safe to do so, and let it be known the STI’s feisty turbo-four craftily providing 305 great ways to get past anything blocking the lane ahead. It launches from standstill with ferocious immediacy and a brilliantly snarling engine note, adding a resonant auditory track to particularly fast-paced visuals. Clutch take-up is ideally weighted with travel short and to the point, while its metal pedals are ideally placed for a little heal, toe action, those uprated brakes fabulously responsive no matter how many times I deep dove into them.
Likewise, the STI’s hydraulic power steering is wonderfully reactive and great at communicating feedback, while its suspension setup is ideally balanced, giving way ever so slightly at both ends when push came to shove, and doing so with a confidence inspiring level of predictability.
This balance is configurable from front to rear via the previously noted DCCD, which lets you lock in an alternative AWD torque split to the otherwise default 41:59 bias, allowing for the characteristics of a rear-wheel drive sports sedan or vice versa, this complemented by a double wishbone rear suspension design as capable of absorbing pavement irregularities as the previously noted struts up front, while always keeping the car horizontal to the road.
This is a car you can comfortably drive fast, plus feel safe, secure and always in control of, but take note it won’t take long before you’ve gone so far past those aforementioned limits that you might be walking home, or at the very least be served up a hefty fine, so keep eyes peeled for party poopers.
If you’re lucky enough to live near a racetrack or have a friend that owns acres of ranchland interconnected with drivable dirt roads, or even if there’s a large parking lot (preferably covered in snow) somewhere nearby, Subaru has your ride, and despite all of the sport compacts that have come and gone since the WRX started wooing us from afar way back in the early ‘90s and finally got real for us here in North America in 2002, or 2004 for the STI, it’s still the all-wheel drive compact to beat.
As I write this review the model year changeover from 2018 to 2019 has occurred, which now gives you an option that might be worth your undivided attention. A near identical version of the STI’s turbocharged 2.5-liter four now includes stronger pistons, a new air intake, new ECU programming and a high-flow exhaust system, resulting in the same torque yet five more horsepower totaling 310, while the gearbox gets a new third gear for quicker acceleration. Lastly, the entry and top-line infotainment systems get some tweaks, but like the new powertrain I’ll need to experience these firsthand before making comment.
Those wanting a bargain can try their luck on a remaining 2018 model, although don’t expect to get too much off as the WRX STI, and all Subarus for that matter, hold their resale values well. Of course, this will be a bonus when it comes time for you to resell, but believe me, handing over the keys to this super-sedan might take more willpower than you can muster.
Yes, if you’re longing for an outrageously competent sports car with the added convenience of four doors and a sizable trunk, look no further than the Subaru WRX STI. Even if you don’t need the back seat and storage, it’s one of the better performance cars available for less than $40k, and thanks to its ever-improving refinements its now a viable alternative for anyone otherwise interested in a premium-branded sport sedan.
