The Subaru XT, XT6, and Alcyone are sporty coupes that were sold new from 1985 to 1991 by Subaru. The XT was sold in Australia and New Zealand as the Vortex and the XT6 was sold in North America and Europe. The Alcyone was sold in Japan. All were available in front wheel drive or all wheel drive (depending on the year).

The XT was replaced by the Subaru SVX in 1992.

The Alcyone is named after the brightest star in the Pleiades star cluster, on which the Subaru logo is based.

[edit] Subaru XT (1985–1991)

Subaru has earned a reputation for designing and marketing unusual vehicles—sometimes successfully, sometimes not. The Subaru XT is no exception. First introduced in February 1985 in the United States (June 1985 in Japan), the XT was a wedged-shaped departure from the 1970s-influenced curves of the previous models, aimed directly at the heart of the 1980s. When introduced, the New York Times called it "the ultimate in jazzy design", in contrast to Subaru's older "cheap and ugly" offerings. Its unusual wedge shape led to the unflattering nickname, "flying doorstop".

A Breakthrough in Automotive Aerodynamics

The extreme wedge body shape was possible due to the engine's flat horizontally opposed cylinder layout shared by all Subarus in 1985. Extensive wind tunnel testing was used to lower wind resistance and even "aircraft type" door handles were used that were totally flush with the outside of the door. You had to push a hinged panel out of the release mechanism's opening to open the door. Rubber spoilers before each wheel well opening doubled as "mud guards" but really acted to direct airflow smoothly past the tyres and wheels. The result was arguably the most aerodynamic production car of its time with a coefficient of drag or Cd of "0.29".

Aircraft-Styled Cockpit

The inside of the car had may aircraft-like features such as pod mounted lighting, heater/ac and wiper controls. The standard tilting-telescoping steering moved the instrument panel to keep it lined up with the steeing column when tilting. The shifter was "joystick" shaped and had a thumb trigger interlock and "on-demand" 4WD engage button. Turbo models featured an sort of "artificial horizon" orange backlit LCD instrument display with the tachometer, boost indicator, temperature and fuel gauges seen as 3D graphs tilting back out to the horizon.

The XT was loaded with features rarely found on small cars, such as a turbocharger, a computer-controlled engine and transmission, adjustable height suspension and an optional digital instrument cluster. The XT also had some features found on few other cars, such as an electronic in-dash trip computer, retractable flaps covering the door handles, and a single wiper blade for the entire windshield. Pass thru fold down rear seats and racing style front seats.

[edit] Drivetrain

The 1985 XT was fitted with two engines:

• EA82: 1781 cc F4 producing 97 hp (72 kW) at 5200 rpm and 103 ft·lbf (140 Nm) at 3200 rpm (9.5:1 compression ratio)
• EA82T: 1781 cc turbocharged F4 producing 111 hp (83 kW) at 4800 rpm and 143 ft·lbf (194 Nm) at 2800 rpm (7.5:1 compression ratio) (Some sources say 7.7:1.) In europe the power of the xt turbo was raised to 136 hp (100 kW)

These engines shared the following equipment and specifications:

• 1781 cc (108.7 in³) displacement (92x87 mm/3.62x3.425")
• Multi-port fuel injection
• Single overhead camshafts (note that because these are flat engines, all are equipped with two such camshafts)

The XT was available with both manual and automatic transmissions. Early XTs were available as either front wheel drive or part-time four wheel drive, selectable by a push button atop the shifter. After 1987, the part time four wheel drive system was replaced with an all wheel drive system.

[edit] Features and options

As mentioned above, the XT was loaded with unusual features. Included on all models were:

• Retractable door-handle flaps
• Single front wiper blade
• Steering wheel with a single vertical and a single horizontal spoke
• Pistol-grip shifter
• Microprocessor engine and transmission management
• Steering wheel with both tilt and reach adjustment
• Instrument cluster that tilted with the steering wheel

Furthermore, some models were equipped with additional features:

• Digital instrument cluster that tilted with the steering wheel
• Trip computer with range/fuel management facilities
• Pneumatic suspension with height control
• Push-button four wheel drive (later changed to all wheel drive)
• Hill holder brake system, prevented rolling on hills in the manual transmission version.

Like other Subaru models of the same vintage, the XT was sold in three models: the base-model DL, the better-equipped GL, and the top-of-the-range GL-10. Many of the options mentioned above were available only on the GL-10.

Two F4-powered derivatives were sold in Japan: the four wheel drive Alcyone VR, and the front wheel drive Alcyone VS. Both were equipped with turbocharged motors.

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. Early XTs are easily distinguished from later models by inspecting the taillight and reverse light configuration - early models had reverse lights in the rear bumper, while 1987 1/2-up models had the reverse lights in the center taillight panel. All wheel drive turbo and six-cylinder models can be distinguished by the shape of the headrests; base models had solid headrests, whereas the turbo AWD and six-cylinder models had a large rectangular hole through the center.

[edit] Subaru XT6 (1988–1991)

Although the XT was available with a turbocharged engine, performance from the 111 hp powerplant wasn't terribly impressive. In 1987, Subaru introduced the XT6 as a 1988 model with the 145 hp 2.7 L flat-six ER27. The XT6 received additional upgrades, including heavier suspension to handle the larger engine and 5-bolt hubs and wheels to accommodate the extra torque.

The XT6 was also 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 was not available with the digital instrument cluster of the regular XT models.

In the Japanese market, the XT6 was sold as the Alcyone VX. No front wheel drive Alcyone VXs were ever sold in Japan, and no XT6s were sold in New Zealand. Subaru New Zealand did however bring in an XT6 as a demo, but as New Zealand's fuel options were 91 octane unleaded fuel or 96 octane leaded fuel, it was not a viable option to sell the XT6 as the 2700 cc 6 Cyl engine required 96 octane unleaded petrol.

Both the regular XT and the XT6 were discontinued after 1991 and were replaced by the much larger Subaru Alcyone SVX. The SVX continued the tradition of surprising gadegtry in a sporty coupe, albeit in a much heavier and more powerful package.

[edit] Market appeal and production

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 111 hp (83 kW) wasn't enough to attract serious attention from the automotive racing crowd. 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, after all.

Subaru produced 98,918 XTs, XT6s, and Alcyones. Surprisingly, only 8,170 of these were sold in the Japanese market.

While the XT exists as a very interesting design exercise, it did little in terms of market development for Subaru. The company has seen much more widespread success in the significantly more mainstream Outback and WRX models introduced in recent years.
