Subaru US Legacy Site
DETROIT – Subaru of America Inc., has introduced the 2005 Legacy 2.5 GT Sedan and Wagon at the 2004 North American International Auto Show. The most powerful Legacy ever offered in the U.S. market, the 2005 Legacy 2.5 GT is powered by a new 250-horsepower intercooled / turbocharged Subaru Boxer engine.

Arriving at Subaru dealerships in spring 2004, the 2005 Legacy 2.5 GT will lead a thoroughly revised model line that includes a Legacy 2.5 GT Limited Sedan and Wagon, which feature additional luxury content. Legacy 2.5i and Legacy 2.5i Limited models, both available as a sedan and wagon, are powered by a naturally aspirated 2.5-liter boxer engine that provides enhanced response for 2005.

With a distinctive fusion of style, performance and function, the Legacy 2.5 GT will deliver on the promise of a premium driving performance experience. Combining strong emotional appeal with intelligent engineering, the new-generation Legacy 2.5 GT will offer stunning performance while remaining true to the core values that make Subaru a unique brand: A boxer engine, standard Symmetrical All-Wheel Drive, a functional and comfortable driver’s environment, a high degree of safety and comfort for passengers and renowned durability and reliability.

“The 2005 Legacy 2.5 GT is designed to provide the kind of ‘sensuous performance’ that truly sets it apart from mainstream models,” said Fred Adcock, Executive Vice President, Subaru of America, Inc. “Legacy 2.5 GT has been designed to give the driver the kind of power, performance and control that instills premium-brand cars with distinct and memorable brand identity,” he added.

All Legacy models for 2005 will feature even greater safety and high-value content than the previous-generation models. Built on a new version of the company’s proven Ring-Shaped Reinforcement Frame safety structure, the 2005 Legacy models will feature as standard equipment side impact air bags, new side curtain air bags and new intelligent dual-stage deployment front air bags.

The 2005 Legacy 2.5 GT is the latest in the brand’s line of exciting turbocharged performance models that Subaru has introduced in the U.S. market since the Impreza® WRX® debuted for the 2002 model year. The rally-bred Impreza WRX STi® followed for 2004, along with the Forester® 2.5 XT and Baja™ Turbo crossover models. These turbocharged All-Wheel Drive performance models reflect the brand’s long-running experience and success in World Rally Championship (WRC) competition.

Bold New Design Strengthens Brand Identity

High-Performance Intercooled / Turbocharged Engine

The 2005 Legacy 2.5 GT is powered by an intercooled and turbocharged 2.5-liter 4-cylinder boxer engine that produces 250 horsepower @ 5,600 rpm and 250 lb-ft. of peak torque @ 3,600 rpm. The engine shares architecture and technology with the engines used in other Subaru turbocharged performance models such as the WRX STi, but most key components – including the cylinder block, turbocharger and intercooler – are unique to Legacy 2.5 GT.

Active Valve Control System (AVCS) variable valve timing technology helps optimize low and mid-range torque and high-end output, and the Legacy 2.5 GT engine is characterized by a wide torque curve for outstanding power at all speeds. All Legacy engines for 2005 use an Electronic Throttle Control (ETC) system, sometimes referred to as “drive by wire” or “throttle by wire.”

Choice of 5-Speed Manual or 5-Speed Automatic Transmissions

The 2005 Legacy 2.5 GT will offer a choice between a smooth-shifting 5-speed manual transmission or an all-new 5-speed electronic direct control automatic transmission with a SPORTSHIFT feature for manual control when desired. The advanced new 5-speed automatic transmission offers a higher degree of control in either automatic or manual mode. Using a lateral-G sensor and cornering logic, the transmission can select and hold the appropriate gear to enhance cornering performance. The transmission will actively downshift to maintain optimal traction and control on inclines, as well.

With the SPORTSHIFT feature, the driver can choose to shift manually using the console shift handle or shift buttons on the steering wheel. When placed in “D,” the lever can be toggled to the left for manual shift control, and then pushed forward for upshifts and pulled rearward for downshifts. The transmission can provide temporary access to manual mode when in “D” by using the steering wheel shift buttons.

Performance-Bred Chassis

A new, stiffer unitized body structure makes greater use of aluminum and high-strength steel, as well as advanced construction techniques including hydroforming and tailored-blank welding. Aluminum parts include the hood and bumper beams and the rear gate on wagons. Using aluminum at the vehicle’s extremes helps to concentrate more mass near its center of gravity, which helps to enhance handling.

The engine in the new Legacy models is mounted lower than in the previous generation, which helps to lower the center of gravity. The proven MacPherson type strut front suspension uses all new components, including aluminum lower L-arms that reduce unsprung weight. A wider track and revised geometry significantly enhance handling and stability. The multilink rear suspension attaches to a new, hydroformed steel sub-frame for added rigidity, and the roll center has been lowered to enhance handling and stability.

Suspension, braking and steering have been optimized to complement the powertrain performance in Legacy 2.5 GT. Legacy 2.5 GT models roll on standard 17 x 7-inch aluminum-alloy wheels with 215/45 R17 all-season tires.

A 4-wheel disc Anti-lock Brake System (ABS) with Electronic Brake-force Distribution (EBD) is standard equipment on all 2005 Legacy models. Legacy 2.5 GT features larger front brake rotors than other Legacy models, as well as ventilated rear discs (solid discs on other models).

The rack-and-pinion steering system in Legacy 2.5 GT has been redesigned for quicker response, greater precision and improved feel. A new, high-strength “cannon mount” secures the steering rack to the front subframe. A damper valve helps prevent the kickback and vibration that would otherwise result from the added stiffness provided by the cannon mount.

Symmetrical All-Wheel Drive A Key To Brand Identity

All-Wheel Drive is a cornerstone of Subaru brand identity, not just an add-on feature. Consistent with this philosophy, all Subaru All-Wheel Drive systems are organized under the “Symmetrical All-Wheel Drive” branding umbrella. Symmetrical All-Wheel Drive is a total system that integrates a lightweight horizontally opposed (boxer) engine and full-time All-Wheel Drive. Symmetrical All-Wheel Drive provides excellent balance thanks to the longitudinally mounted boxer engine and the way power flows from it through the transmission and to the rear differential along a straight, near-horizontal path.

Subaru offers three different Symmetrical All-Wheel Drive systems in the 2005 Legacy models, each tailored to the type of transmission. With the 5-speed manual transmission, the system uses a viscous-coupling locking center differential to distribute the power 50/50 front to rear. Slippage at either set of wheels will send more power to the other set of wheels.

Legacy 2.5 GT models equipped with the 5-speed automatic transmission use a system called Variable Torque Distribution (VTD). A planetary center differential works with an electronically controlled continuously variable hydraulic transfer clutch to manage power distribution. The system normally sends more power to the rear wheels to enhance handling agility, and it continuously adjusts the power distribution in response to driving and road conditions.

Legacy 2.5i and Legacy 2.5i Limited models will offer an optional 4-speed automatic transmission, with an AWD system that uses an electronically managed continuously variable transfer clutch to actively control power distribution in response to driving conditions.

All-New Interior Designed for True Grand Touring

Subaru redesigned the roomy Legacy interior and used high-quality materials to enhance the driver’s environment and passenger comfort. The new unified design integrates the entire area from the instrument panel and large center panel to the console box. Flush surface treatments, a soft foam upper dashboard, soft foam door trim and aluminum side sill covers with the Subaru logo provide a premium appearance and ambience.

The sporty new four-dial instrument panel features an electroluminescent LED (light-emitting diode) gauge display in Legacy 2.5 GT. On startup, the needle pointers swing to their maximum positions and then back, as in the Impreza WRX STi. The gauge panel is augmented in all models by a combination digital clock and trip computer, located in the center of the dashboard. Some of its functions and displays include outside air temperature, fuel consumption, remaining driving distance, estimated driving time, and a passenger airbag on/off indicator light.

The 2005 Legacy 2.5 GT comes equipped with premium performance features that include as standard equipment a dual-zone automatic climate control system, performance-design front seats with 4-stage heating and heated exterior mirrors. The MOMO®-designed 3-spoke leather-wrapped steering wheel features integrated SPORTSHIFT controls when the car is equipped with the optional 5-speed automatic transmission.

The standard audio system includes a 120-watt AM/FM stereo, a 6-disc in-dash CD changer and six speakers. Larger controls and displays make the audio system easy to use, and all power window and seat switches are illuminated for ease of use.

Legacy 2.5 GT Limited models add a more luxurious interior featuring leather-trimmed upholstery, an 8-way power driver’s seat and a 4-way power passenger seat. A glass power moonroof is standard on all Legacy GT Limited and Legacy 2.5i Limited models. The moonroof on the wagon models is a new-design dual-panel type that provides a single large opening when the tilt-up front section and retracting rear section are opened.

A remote keyless entry system is standard for all 2005 Legacy models, with the system in Legacy 2.5 GT and

2.5 GT Limited models adding an engine immobilizer function. The remote control includes a trunk release for sedans and a rear gate release for wagons.

A versatile center console integrates two cupholders, a console box with a shutter-type lid and a height-adjustable armrest. The storage box will hold nine CDs and also has a 12-volt power outlet. The 2005 Legacy wagon models feature a new, one stage 60/40 split rear seatback that provides a flat load floor without the need to lift the rear seat cushion forward. The sedan’s trunk hinges are fully encased and do not intrude into the cargo area.

Safety Taken To A New Level

Symmetrical All-Wheel Drive, 4-channel / 4-sensor ABS, excellent handling response and expansive visibility give the 2005 Legacy models a high degree of active safety (the tools that help a driver avoid hazardous situations). The foundation of passive safety in the 2005 Legacy models is a redesigned Ring-Shaped Reinforcement Frame structure that incorporates larger cross-section frame members and straighter rear frame sections than before.

The front-end structure disperses collision energy in three directions, and new hydroformed center pillars enhance side impact protection, which is further bolstered by repositioned side impact door beams. The increased focus on side impact safety continues inside, where all Legacy models for 2005 feature standard front seat-side impact air bags for thorax-area protection and side curtain air bags (full side coverage) for head protection.

A new intelligent air bag system employs dual stage deployment driver and front passenger air bags. A seat position sensor on the driver’s seat track detects if driver is sitting too close to the air bag, in which case the system would delay deployment of the air bag’s second stage. The passenger side front seat incorporates an occupant detection module that detects weight on the passenger seat and determines if it’s a child or adult to control air bag deployment. All Legacy models for 2005 feature active front head restraints, which can help reduce potential whiplash injury in a rear collision. A new safety brake pedal system can help reduce lower leg injury in a frontal collision.
