The 2006-2009 Subaru Legacy IV 2.5i GT was a notable offering from Subaru in the mid-size sedan market. Based on the BL/BP platform initially launched in 2003, the facelifted model received cosmetic refinements and focused on improving the overall driving experience. The “2.5i GT” designation indicated the inclusion of the 2.5-liter turbocharged engine, previously exclusive to the Outback XT. This variant was designed to appeal to drivers who wanted a more dynamic driving experience without sacrificing the practicality and all-weather capability that the Legacy was known for. It was primarily marketed in North America, where all-wheel-drive vehicles were in high demand.
Powertrain & Engine Architecture
The core of the 2.5i GT is the EJ255, a 2.5-liter horizontally-opposed (boxer) four-cylinder engine. A single turbocharger with an intercooler boosts the engine’s output to 250 horsepower at 6000 rpm and 339 Nm (250 lb-ft) of torque at 3600 rpm. The EJ255 features multi-port fuel injection and a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder. The boxer engine configuration contributes to a lower center of gravity, improving handling and stability. Crucially, the 2.5i GT was exclusively available with a five-speed manual transmission, giving drivers complete control over the engine’s power. This transmission choice was made to complement the engine’s performance characteristics and appeal to driving enthusiasts. The engine requires 4 liters of oil and 7.4 liters of coolant for optimal operation.
Driving Characteristics
The 2.5i GT provided a significantly more engaging driving experience than the naturally aspirated Legacy models. The turbocharger delivers a noticeable surge of power in the mid-range, making overtaking and highway merging easy. While not a dedicated sports sedan, the 2.5i GT offers respectable acceleration and a responsive feel. The five-speed manual transmission allows for precise gear selection, and Subaru’s symmetrical all-wheel-drive system provides excellent traction in various weather conditions. Compared to the automatic transmissions offered in other Legacy trims, the manual gearbox in the 2.5i GT provides a more direct connection to the engine and a more involved driving experience. The gear ratios are carefully tuned to balance acceleration and fuel efficiency, maximizing the engine’s torque output.
Equipment & Trim Levels
The 2.5i GT trim came standard with several features designed to enhance comfort and convenience. These included alloy wheels, a sport-tuned suspension, and a rear spoiler. The interior featured sport seats with unique upholstery, a leather-wrapped steering wheel, and a premium audio system. Optional extras included a sunroof, heated front seats, and a navigation system. The interior design was functional and well-built, though it didn’t quite match the luxury appointments found in some European competitors. The emphasis was on providing a comfortable and practical cabin for everyday use.
Chassis & Braking
The Legacy IV used a MacPherson strut front suspension and a double-wishbone rear suspension. The 2.5i GT benefited from a slightly stiffer suspension tuning compared to other Legacy models, further enhancing its handling. The braking system consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the vehicle’s weight and performance. Anti-lock brakes (ABS) were standard. The all-wheel-drive system utilized a variable torque distribution, automatically adjusting the power split between the front and rear wheels based on road conditions and driver input.
Market Reception & Comparison
The 2.5i GT was generally well-received by automotive critics, who praised its performance, handling, and all-weather capability. Some reviewers, however, noted that the interior lacked the refinement of some competitors. Compared to the naturally aspirated Legacy models, the 2.5i GT offered a substantial performance upgrade, but with slightly reduced fuel economy. Compared to the Outback XT, the Legacy 2.5i GT offered a more traditional sedan body style and a slightly more focused driving experience. Reliability was generally good, although some owners reported issues with the turbocharger and the EJ255 engine’s head gaskets – a common concern with Subaru engines from this period.
Legacy
The Subaru Legacy IV 2.5i GT remains a popular choice among enthusiasts looking for an affordable and capable all-weather performance sedan. The EJ255 engine, while known for potential head gasket issues, is generally considered robust and can be reliably maintained with proper care. The availability of aftermarket performance parts allows owners to further enhance the engine’s power and handling. In the used car market, the 2.5i GT typically commands a higher price than other Legacy models due to its performance and relative rarity. Its combination of practicality, performance, and all-wheel-drive capability ensures its continued appeal to a dedicated following.
