The Subaru XT is a 2+2 car[1] manufactured and marketed by Subaru from 1985 till 1991, with a facelift in 1987. It is a two-door coupé with a front-mounted engine and either front-wheel drive or all-wheel drive. When the XT debuted, it was the most aerodynamic car in the US market.[1]
Marketed as the Alcyone in Japan; as the Vortex in Australia and New Zealand; and as the XT (with the EA-82 four-cylinder engine) or XT6 (with the ER-27 six-cylinder engine) in North America and Europe, all XT cars were assembled at Subaru's Yajima Plant in Ota, Japan. Over its single generation, production reached just over 98,000.[2]
The XT was conceived in the United States for the US market, and thus debuted globally in the US.[1] After sales began in February 1985 in the US, the XT Turbo 4WD's debuted in Europe at the March 1985 Geneva Motor Show,[3] followed by its Japanese debut in June 1985.[4]
The XT was noted for its pronounced wedge shape, low coefficient of drag; aviation influences from the aircraft division of parent company Fuji Heavy Industry; and its host of features, either innovative or uncommon in the XT's class — including height-adjustable pneumatic suspension, digital dash, central locking system, op-art upholstery, fold down rear seat, pod- and center console-mounted HVAC controls, advanced trip computer, and instrument cluster which tilted with adjustment of the steering column. With available front-wheel drive or four-wheel drive, depending on the model year, the XT offered three trim levels, DL, GL (non-turbo, front-drive only), and GL-10 Turbo.[1]
The Alcyone name was derived from Alcyone, the brightest star in the Pleiades star cluster, which is also included in the Subaru logo with some stylisation. The model was succeeded by the Subaru Alcyone SVX in 1992.
Design
[edit]
The XT featured a pronounced wedge shape, sharing a common "folded paper" design approach with the Type AA Subaru Leone. When introduced, the New York Times called it "the ultimate in jazzy design",[5] in contrast to Subaru's other offerings. Though derived from earlier Subarus, it was less overtly practical or commodious. The 2.7-litre flat-six engine exceeded 2000 cc in the Japanese Domestic Market, thereby exceeding government engine displacement regulations, and incurring higher annual road tax.
The XT's exterior design team was led by Kiyoshi Sugimoto, with the interior team led by Hiroshi Yako, under the guidance of Tetsuya Hayashi. Some sources credit Kyuchi Akari with the final design, with notable inspiration from American designer Alex Tremulis, who had instructed Akari in aerodynamic principles and noted areas of possible flow separation.[1]
Aerodynamics
[edit]Subaru's trademark boxer engine with its flat, horizontally opposed cylinder configuration, enabled the bodywork's pronounced wedge shape, and extensive wind tunnel testing further lowered the XT's coefficient of drag. Pop-up headlights contributed to the wedge shape, and retractable button-like flaps allowed opening the door while keeping the handles flush with their adjacent bodywork. The XT used a single 22 inch windshield wiper which tucked under the hood when not in use, and rubber spoilers ahead of each wheel opening settled the airflow past the tires and wheels, while doubling as "mud guards." The result was the most aerodynamic production car sold in America at the time of its release with a coefficient of drag of 0.29,[4] improved fuel economy, and a quieter ride due to reduced wind noise.
Features
[edit]The XT's interior used numerous aviation-like features, reflecting influences from the aircraft division of Subaru's parent company, Fuji Heavy Industries. The instruments featured pod-mounted controls for lighting, HVAC and wipers. The instrument panel moved with the standard tilt-telescope steering to keep the instruments oriented to the driver, recalling the same feature on the Isuzu Piazza and the Ford Probe introduced earlier in the 1980s and the Porsche 928 in the late 1970s. The joystick-shaped shifter integrated a thumb trigger interlock for the "on-demand" four-wheel drive. Turbo models featured a quasi-artificial horizon orange backlit liquid crystal instrument display with the tachometer, boost indicator, temperature and fuel gauges seen as three-dimensional graphs oriented to the quasi-horizon.
The XT featured a turbocharger, computer-controlled engine and transmission, adjustable height suspension[4] and an optional digital instrument cluster. The pneumatic with height control recalled the use of Hydropneumatic suspension by Citroën, and Mercedes-Benz. Other uncommon features included an electronic in-dash trip computer, headlight washers (XT6 only), alloy wheels featuring an inset rectangular shape, pass-through folding rear seats, sporty front bucket seats and available push-button four-wheel drive (later changed to all-wheel drive).
The XT featured a speed alarm at 55mph, that could be activated with a separate key.[1]
1985–1987 (Pre-facelift)
[edit]
The XT was launched initially as the XT in North America, Alcyone in Japan and Vortex in Australia and New Zealand. The pre-facelift XT was only powered by an H4 and was produced from 1985 to 1987.
Drivetrain
[edit]The 1985 XT was fitted with one of two engines for the US market:
- EA-82: 1781 cc H4 producing 97 hp (72 kW) at 5200 rpm and 103 lb⋅ft (140 N⋅m) at 3200 rpm (9.5:1 compression ratio).
- EA-82T: 1781 cc turbocharged H4 producing 112 hp (84 kW) at 4800 rpm and 143 lb⋅ft (194 N⋅m) at 2800 rpm (7.5:1 compression ratio; some sources say 7.7:1.) in North American specifications. In Europe the power of the XT Turbo was 136 PS (134 hp; 100 kW) at 5600 rpm and 197 N⋅m (145 ft⋅lb) at 2800 rpm;[6] the naturally aspirated model was not sold there. Starting in 1987, power for North American cars increased to 115 hp (86 kW).
These engines shared the following equipment and specifications:
- 1,781 cc (109 cu in) displacement (92×67mm/3.62×2.63")
- Multi-port fuel injection
- Single overhead camshafts

The XT was available with both manual and automatic transmissions. 85-87 XT Turbos were available as either front-wheel drive or part-time four-wheel drive, while the 85-87 XT non turbo cars were only available as front-wheel-drive. The part-time four-wheel-drive system, titled "On-Demand", was selectable by a push button atop the shifter.
Markets
[edit]Like other Subaru models of the same vintage, the North American market XT was sold in four models: the base-model XT DL, the better-equipped XT GL, the top-of-the-range FWD XT GL-10 Turbo and 4WD XT GL-10 Turbo-Traction. Many of the options mentioned above were available only on the GL-10 models.
In Japan it was only available as 2 turbocharged models: the Alcyone 4WD VR Turbo, and the Alcyone FF VS Turbo.
Australia and New Zealand also got 2 models, the turbocharged Vortex Turbo and the non-turbocharged Vortex XT. Initially the Vortex was only available as the non-turbocharged manual Vortex XT, but the turbo version and automatic gearbox came the following year.
European markets generally only received the XT Turbo and the XT Turbo 4WD (XT Turbo Allrad in Germany), where the car was sold in small numbers as a halo model.

1987–1991 (Facelift & XT6)
[edit]
The XT received a minor update in 1987 for the second half of the 1987 model year roughly corresponding to the 1988 launch of the XT6, a new 6 cylinder model. Where earlier models featured bumper-mounted reverse lights, 19871⁄2-up models had the reverse lights in the center taillight panel. The front and rear bumpers were also redesigned. In Japan, the original bumpers were used for the VS and VR while the VX received the new facelift. In the US, all new models received the facelifted bumpers.
All wheel drive turbo and six-cylinder models were distinguished by their headrests; base models had solid headrests, where the turbo AWD and six-cylinder models had a large rectangular hole through the center.
Drivetrain
[edit]
The 1987 XT was fitted with one of 3 engines
- EA-82: 1781 cc H4 producing 97 hp (72 kW) at 5200 rpm and 103 ft·lbf (140 Nm) at 3200 rpm (9.5:1 compression ratio).
- EA-82T: 1781 cc turbocharged H4 producing 115 hp (86 kW) at 4800 rpm and 143 ft·lbf (194 Nm) at 2800 rpm (7.5:1 compression ratio; some sources say 7.7:1.).
- ER-27: 2672 cc H6 producing 145 hp (108 kW; 147 PS) at 5,200 rpm and 156 ft⋅lb (212 N⋅m) at 4,000 rpm.
6 cylinder models were fitted with stiffer suspension to compensate for the new heavier engine.
Markets
[edit]
In North America the updated XT was sold in 2 models: The base 4 cylinder model GL, and the new 6 cylinder model XT6. The turbo models were dropped from the North American market after the update.[7]
In Japan, the updated XT was sold in 3 models: The turbocharged FWD VS, the turbocharged 4WD VR, and the new 6 cylinder 4WD Alcyone VX.
In New Zealand, the new 6 cylinder model was marketed as the Vortex ZZ6. However, few were sold due to New Zealand's fuel options, which were 91 octane unleaded fuel or 96 octane leaded fuel. The ER27 required 96 octane unleaded petrol. Today, there are only two NZ new 6 cylinder Vortexes registered according to NZTA fleet data.
In Japan, the part-time 4WD system was replaced entirely by the new full-time 4WD system. In the US, the XT6 was available in either FWD or with the new full-time 4WD system while the XT GL was available with either FWD or the old "On-Demand" 4WD.
Features and options
[edit]This article needs additional citations for verification. (November 2022) |
The XT6 was fitted with a unique Cybrid adaptive electrohydraulic steering system that changed the level of assistance based on the vehicle's speed. This system did not use a conventional belt-driven power steering pump, freeing up much-needed space in the XT6's already cramped engine bay. The Cybrid system also uses hydraulic fluid that is incompatible with conventional power steering fluid (which is usually automatic transmission fluid). This fluid is still available directly from Subaru at a significant premium over more common types of hydraulic fluid.
The XT6 has two electric fans to also help performance, compared to one electric fan and one belt driven fan on all other XTs. With these changes, the XT6 was given a higher amp alternator.
The XT6 was not available with the digital instrument cluster of the turbo XT models.
Special editions
[edit]A special "30th Anniversary" version of the Alcyone VX was produced in 1988, limited to 30 units. This version had a white and gold paint job with "30th Anniversary" side decals and a red interior.
2 prototype versions of the Alcyone VX were made in Japan for the 27th Tokyo Motor Show. The "Junko Shimada" was one that included a full black paintjob with black smooth wheel caps and a bright red leather interior, designed by Japanese fashion designer, Junko Shimada. The other was the "FICCE Special" which was a convertible version of the Alcyone with special hubcaps and interior graphics designed by Yoshiyuki Konishi. The FICCE is allegedly sitting in the Ibaraki Prefecture in need of restoration.[8]

Market appeal and production
[edit]This article needs additional citations for verification. (November 2022) |
Overall production of the XT remained low throughout its lifespan. Although the fuel crisis of the late 1970s and ever-tightening emissions regulations had severely limited power figures from all manufacturers in the mid 1980s, the XT's paltry 134 hp (100 kW) wasn't enough to attract serious attention from the automotive racing crowd.[9] One of Subaru's ads from the 1980s read, The kind of car Mercedes might have built if they were a little more frugal and a lot more inventive. The car's extra features, which certainly had some novelty appeal, were uncharacteristic of this class of car and may not have contributed much to the XT's sales. In the 1980s, consumers with surplus cash in search of a better-equipped vehicle did not generally start shopping at Subaru.
Subaru produced 98,918 XTs, XT6s, and Alcyone's.[10] Surprisingly, only 8,170 of these were sold in the Japanese market.
While the XT was an interesting design exercise, it did little to grow Subaru's sales. The company has seen much more widespread success in the significantly more mainstream Legacy, Legacy Outback and Impreza WRX models introduced in recent years.
The Subaru XT Turbo was the official car for the Most Valuable Player for Super Bowl XXII presented by SPORT magazine in 1988, eventually won by Washington Redskins quarterback Doug Williams, and The Subaru XT6 was the official car for the Most Valuable Player for Super Bowl XXIII in 1989, eventually won by San Francisco 49ers wide receiver Jerry Rice.
Motorsports
[edit]The XT was almost never officially used for racing. One exception is the 1985 Wynn's Safari Australia where one XT competed, however it received damage and was not able to finish.

Introduction
The Subaru XT is a 2+2 sports coupe manufactured by Subaru from 1985 to 1991, with a total of 98,918 units assembled at the company's Yajima Plant in Ota, Gunma Prefecture, Japan.[5][2][6] Marketed under different names regionally, it was known as the Alcyone in Japan, the Vortex in Australia and New Zealand, and the XT or XT6 in North America and Europe, depending on the engine configuration.[7][2] This model represented Subaru's venture into more stylish, performance-oriented vehicles while retaining the brand's signature boxer engine and optional all-wheel-drive system. The XT stood out for its innovative design, featuring a distinctive wedge-shaped "folded paper" aesthetic inspired by origami and aviation themes, complete with pop-up headlights and flush-mounted door handles to minimize drag.[8] At launch, it achieved a drag coefficient of 0.29, making it the most aerodynamic production car available in the United States market and Subaru's first vehicle to prioritize such advanced aerodynamics.[9][10] Initial powertrain options included a naturally aspirated 1.8-liter EA-82 flat-four engine producing 97 horsepower or a turbocharged EA-82T variant delivering 112 to 115 horsepower, paired with either front-wheel drive or Subaru's part-time four-wheel-drive system.[2][11] The XT served as a bridge in Subaru's lineup toward more premium offerings, paving the way for its successor, the Subaru SVX, introduced in 1992.[12]Development History
The Subaru XT was developed in the early 1980s by Fuji Heavy Industries as Subaru's entry into the premium coupe segment, largely at the urging of Subaru of America executives who sought a sporting flagship to appeal to a more affluent U.S. audience and elevate the brand beyond its reputation for affordable, practical vehicles.[3] Harvey Lamm, then-president of Subaru of America, played a key role in convincing Fuji Heavy Industries to prioritize this project, aiming to position the XT as a "gentleman's sports car" that combined Subaru's engineering strengths with upscale styling.[3] The overall concept was guided by designer Tetsuya Hayashi, with the exterior led by Kiyoshi Sugimoto and the interior by Hiroshi Yako, drawing on influences from aviation aesthetics—reflected in the cockpit-like dashboard—and origami-inspired angular folds for a distinctive, futuristic wedge shape.[13] Subaru's established rally heritage, which had honed its all-wheel-drive technology since the 1970s, informed the XT's drivetrain integration, while the design targeted competition against luxury coupes from brands like Mercedes-Benz by emphasizing refinement and performance.[14] The project progressed from conceptualization in 1982–1983 and prototyping in 1984 to the production model's unveiling at the North American International Auto Show (Detroit) in January 1985, followed by market launches in the United States in February 1985 and Japan as the Alcyone in June 1985.[15][16] Development faced significant challenges in packaging a practical 2+2 seating layout alongside Subaru's symmetrical all-wheel-drive system within an aerodynamically efficient body, requiring compromises between visual drama and functional space.[17] Initial testing emphasized wind tunnel evaluations at Fuji Heavy Industries to optimize airflow, achieving a low drag coefficient through iterative refinements to the body's contours and features like pop-up headlights.[18]Design and Engineering
Exterior Styling
The Subaru XT was characterized by its bold, low-slung wedge-shaped silhouette, which emphasized a sporty and futuristic aesthetic uncommon for Subaru's lineup at the time. This profile featured a sharply angled nose rising toward a higher rear deck, creating a dynamic visual flow that highlighted the car's coupe proportions. The overall design drew inspiration from aviation elements, including flush-mounted door handles that retracted to maintain a smooth exterior surface.[2][19][20] Key exterior accents included pop-up headlights that concealed the lamps when not in use, contributing to the clean lines of the front fascia, and a single large windshield wiper that swept across the expansive glass for efficient clearing. Integrated spoilers positioned ahead of the front wheels added subtle aggression while aiding in airflow management. The body utilized unibody construction typical of Subaru's engineering approach, built primarily from steel for durability and rigidity in a two-door configuration. Dimensions for the base model measured approximately 4,450 mm in length, 1,690 mm in width, and 1,300 mm in height, providing a compact yet spacious footprint.[11][21][22] Color options spanned standard solid and metallic palettes, with special editions offering two-tone schemes such as Liberty White over Gull Gray to accentuate the wedge contours. Over the production run, the exterior saw minor evolutions through a 1987 facelift, including revised taillight designs for a refreshed rear appearance, while preserving the core styling ethos. These visual elements not only defined the XT's unique identity but also supported aerodynamic efficiency, as explored further in dedicated analyses.[23][16]Aerodynamics
The Subaru XT achieved a notably low drag coefficient of 0.29, making it one of the most aerodynamic production vehicles available upon its 1985 debut. This efficiency stemmed from targeted engineering solutions, including smooth underbody panels that reduced turbulent airflow beneath the vehicle, a tapered nose derived from its distinctive wedge profile to minimize frontal resistance, and a Kammback rear design that truncated the body to optimize airflow separation while maintaining practicality.[11] Subaru conducted extensive wind tunnel testing at its facilities to refine these elements, focusing on minimizing aerodynamic lift and turbulence across various speeds and configurations. The development process balanced drag reduction with considerations for engine cooling, noise levels, visibility, and debris management, ensuring the design's real-world viability.[2] Key aerodynamic aids included a fixed rear spoiler that helped control rear-end lift for enhanced high-speed stability, alongside specially shaped side mirrors designed to reduce drag and vortex formation. These features contributed to the XT's superior aerodynamics compared to contemporaries, such as the Porsche 944 with a 0.34 Cd or the standard BMW E30 3 Series at approximately 0.38 Cd.[24][25][26] The aerodynamic optimizations directly influenced performance, enabling reduced fuel consumption—particularly beneficial for highway driving—and supporting higher top speeds, with turbocharged models reaching up to 124 mph. This low-drag profile also resulted in minimal wind noise, measured at 69 dBA at 70 mph, enhancing overall efficiency and comfort.[27][3]Interior and Features
The Subaru XT featured a distinctive 2+2 seating configuration designed for sporty driving, with form-fitting high-back bucket seats upholstered in bold-patterned cloth as standard across most trims, though leather upholstery was available as an option on higher-end models like the GL and Turbo variants.[28] The front seats offered adjustable cushion rake and were positioned lower than those in contemporary Subaru sedans for a more dynamic feel, providing ample space with 37.4 inches of headroom, 43.3 inches of legroom, and 52.8 inches of shoulder room.[3] Rear seats were compact, suitable only for small passengers or children, and could fold down to expand cargo capacity to 12 cubic feet in the trunk.[29] This layout prioritized front occupant comfort while maximizing practicality for occasional rear use or storage. The dashboard and controls embodied the XT's futuristic, aviation-inspired theme, particularly in pre-facelift models from 1985 to 1987, which utilized analog gauges including a tachometer, fuel level, and temperature readouts, complemented by a quartz digital clock and full instrumentation.[28] Controls were integrated into ergonomic pods with touch switches for functions like climate, cruise control, lights, and the single articulated windshield wiper, while the gear shift resembled a fighter jet joystick topped with a red 4WD engagement button.[3] A tilt and telescoping steering column with an asymmetrical wheel enhanced driver adjustability. The 1987 facelift introduced an optional electronic digital instrument cluster on non-XT6 models, featuring a pictograph display with tachometer, boost gauge (on Turbo variants), and an artificial horizon-style layout, though analog gauges remained standard.[3] Comfort options emphasized convenience and refinement, with standard power windows and door locks on GL and Turbo trims, an optional power sunroof, and air conditioning that was standard on Turbo models but optional on base DL and GL versions.[28] The audio system varied by trim, from a basic two-speaker AM/FM on the DL to a 20-watt four-speaker AM/FM electronic tuner receiver on the Turbo, often integrated with a center console. The facelift models benefited from improved HVAC performance, including dual electric cooling fans for better cabin ventilation and efficiency in varied conditions.[3] Safety features were basic by modern standards but aligned with 1980s expectations, lacking anti-lock brakes (ABS) across all variants; instead, the XT relied on a reinforced body structure and Subaru's symmetrical all-wheel-drive system for enhanced traction in wet or slippery conditions.[3] Three-point seatbelts were standard for front occupants, with a speed alarm that activated at 55 mph to promote safer driving, and tinted glass along with a rear defogger contributed to visibility. The XT6 variant introduced unique technology with its Cybrid power steering system, a computer-controlled electro-hydraulic setup using an electric motor-driven pump independent of the engine, providing quicker response with just 3.2 turns lock-to-lock and variable assist.[30] Additionally, the XT6 equipped a higher-output 90-amp alternator to support its array of electrical accessories without straining the system.[31]Drivetrain Specifications
The Subaru XT featured a range of boxer engines typical of Subaru's engineering philosophy, emphasizing a low center of gravity for improved handling. The base model utilized the EA-82 SOHC flat-four engine, a 1.8-liter (1,781 cc) unit producing 94 horsepower at 5,200 rpm and 101 lb-ft (137 Nm) of torque.[32] The turbocharged variant, EA-82T, also 1.8 liters, delivered 111 horsepower at 4,800 rpm and 134 lb-ft (182 Nm) of torque in automatic guise, with manual versions reaching up to 134 horsepower and 145 lb-ft (196 Nm) depending on market tuning.[33][34] From 1988, the XT6 introduced the ER-27 DOHC flat-six engine, displacing 2.7 liters (2,672 cc) and generating 145 horsepower at 5,200 rpm alongside 156 lb-ft (212 Nm) of torque, marking Subaru's first use of a six-cylinder in a compact sports coupe.[35] Transmission options prioritized driver engagement with a standard five-speed manual gearbox across all models, featuring gear ratios such as 3.545:1 in first, 1.947:1 in second, 1.366:1 in third, 0.972:1 in fourth, and 0.738:1 in fifth, paired with a 4.111:1 final drive for balanced acceleration and cruising.[36] Pre-facelift models (1985–1987) offered a three-speed automatic as an alternative, while the 1987 facelift and XT6 upgraded to a four-speed automatic for smoother shifts and better efficiency.[37] These transmissions were longitudinally mounted, integrating seamlessly with the boxer engines to maintain Subaru's symmetrical layout. Drivetrain configurations began with front-wheel drive on base GL models for cost efficiency, but most XT variants emphasized all-wheel drive capability. The part-time four-wheel-drive system, known as "On-Demand," employed a viscous coupling in the center differential to engage the rear wheels automatically under slip, typically distributing up to 50% torque rearward as needed.[38] The XT6 elevated this to a full-time four-wheel-drive setup with a 50:50 front-rear torque split under normal conditions, utilizing a bevel-gear center differential and viscous limited-slip elements for constant traction without driver intervention.[39] Suspension was independent at all four corners, employing MacPherson struts front and rear with coil springs and anti-roll bars for composed handling in a liftback coupe.[3] Braking used ventilated front discs and solid rear drums on base models, upgrading to four-wheel discs on turbo and XT6 variants; the turbo model's setup enabled a 0–60 mph time of approximately 8.7 seconds, underscoring its sporty credentials despite modest power.[40] Fuel economy reflected the era's technology, with non-turbo models achieving 22–25 mpg combined per EPA estimates, while turbocharged versions dropped to around 20 mpg combined due to the added boost and weight.[41]| Engine | Displacement | Horsepower | Torque | Configuration |

Model Generations
1985–1987 Pre-Facelift
The Subaru XT pre-facelift models marked the debut of Subaru's innovative sports coupe, first unveiled at the 1985 Tokyo Motor Show as the production evolution of the ACX-II concept.[20] Designed for the North American market, U.S. sales began in February 1985, positioning the XT as a stylish alternative to mainstream coupes with its aerodynamic wedge shape and advanced features like optional digital instrumentation.[17] The initial lineup offered four trim levels: the entry-level DL, mid-range GL, and performance-oriented GL-10 Turbo (front-wheel drive), with the GL-10 Turbo 4WD adding optional part-time four-wheel drive for enhanced traction.[42] These models were exclusively powered by the EA82 1.8-liter horizontally opposed four-cylinder engine, available in naturally aspirated or turbocharged forms, paired with five-speed manual or three-speed automatic transmissions; full-time all-wheel drive and flat-six engines were not introduced until later iterations.[3] The base DL and GL trims featured the naturally aspirated EA82 engine producing 97 horsepower and 103 lb-ft of torque, emphasizing fuel efficiency and everyday usability with front-wheel drive as standard.[22] In contrast, the GL-10 Turbo variants utilized the turbocharged EA82T, initially rated at 112 horsepower and 143 lb-ft of torque in 1985, providing a modest performance boost suitable for the era's expectations but notable for its responsive low-end delivery when equipped with the manual transmission.[43] By 1987, minor updates refined the lineup, including revised badging for improved visual distinction and a slight power increase to 115 horsepower for the turbo models through optimized fuel mapping, without altering the core drivetrain architecture.[44] The part-time 4WD system, available only on turbo models, engaged the rear wheels manually via a dashboard switch, aiding in slippery conditions but adding approximately 200 pounds to curb weight.[3]| Trim Level | Engine | Horsepower | Drivetrain Options | 1985 MSRP |
|---|---|---|---|---|
| DL | 1.8L EA82 | 97 hp | FWD | $8,139 |
| GL | 1.8L EA82 | 97 hp | FWD | $10,149 |
| GL-10 Turbo | 1.8L EA82T | 112 hp | FWD | $12,776 |
| GL-10 Turbo 4WD | 1.8L EA82T | 112 hp | Part-time 4WD | $13,621 |
1987–1991 Facelift and XT6
In 1987, the Subaru XT underwent a mid-cycle facelift that introduced several refinements to enhance its market positioning and performance. Key updates included a revised front fascia with updated grille and headlight surrounds for a more contemporary appearance, the addition of a four-speed automatic transmission option across models, and the discontinuation of the turbocharged variant in the U.S. market by the end of the year. These changes aimed to broaden appeal while maintaining the XT's aerodynamic profile and innovative features.[47] The facelift also marked the introduction of the XT6 variant in late 1987, initially for the 1988 model year, positioning it as Subaru's flagship sports coupe with a focus on refined power delivery and all-wheel-drive capability. Powered by the new ER-27 2.7-liter horizontally opposed six-cylinder engine producing 145 horsepower at 5,200 rpm and 156 lb-ft of torque at 4,000 rpm, the XT6 replaced the previous turbo four-cylinder setup. This engine was paired exclusively with full-time all-wheel drive, a significant upgrade over the part-time system in earlier models, contributing to improved traction and handling stability. The XT6 featured the innovative Cybrid electro-hydraulic power steering system, which used a dedicated electric motor to vary assist levels based on vehicle speed, providing lighter effort at low speeds and firmer response at highway velocities for enhanced driver control. Priced starting at approximately $17,716 for the all-wheel-drive automatic version, the XT6 targeted buyers seeking a premium, performance-oriented alternative in Subaru's lineup.[48][30][49] Interior updates during the facelift included the replacement of the pre-facelift's digital instrument cluster with conventional analog gauges on the XT6, simplifying maintenance while retaining the distinctive asymmetrical steering wheel for ergonomic comfort. Suspension enhancements comprised recalibrated self-leveling air springs, upgraded shocks, and larger wheels with performance tires, resulting in sharper handling and better ride compliance. Braking was improved with four-wheel discs standard on the XT6. With the introduction of the XT6, the turbo models were no longer available in the U.S., leaving the XT6 as the top offering, with minor interior refreshes in 1990 such as updated trim materials for a more upscale feel. Production of the XT series concluded in 1991.[48][50] The XT6's full-time all-wheel drive and increased power addressed earlier criticisms of underpowered acceleration, though its curb weight of approximately 2,800 pounds tempered outright sportiness. Independent testing recorded 0-60 mph times of 9.0 seconds for the five-speed manual version and 9.8 seconds for the four-speed automatic, aided by the H6 engine's smoother torque delivery and the drivetrain's grip in varied conditions. These attributes made the XT6 Subaru's most sophisticated coupe to date, praised for its balanced dynamics despite the added mass.[30][51][52][10]| Model Variant | Engine | Power/Torque | Transmission | Drivetrain | Curb Weight | 0-60 mph |
