On May 23, 2003, Fuji Heavy Industries debuted the fourth generation Legacy B4 Sedan and Touring Wagon for the Japanese Domestic Market. The Legacy was presented the 2003–2004 Japan Car of the Year, Subaru's first win for the award. In Japan, the Legacy was no longer regarded as a "small car" under Japanese vehicle size legislation due to its length over 4.7 meters, and width dimensions over 1.7 meters. The ground clearance is 5.9in (150 mm).
Starting with this generation, Subaru installed an electroluminescent instrument cluster which lights up when the engine is started, regardless if the exterior lights are on.
For the home market, the Legacy B4 and Touring Wagon were offered in 2.0i, 2.0R, 2.0GT, 2.0GT spec.B, 3.0R, and 3.0R spec.B trim levels. The base model 2.0i has SOHC version of EJ20 engine producing 140 PS, and the 2.0R comes with 170 PS DOHC engine.

To commemorate Subaru's 50 years of making automobiles, the 50th Anniversary Legacy was released in January 2004. This special edition model was based on the Legacy 2.0R, and 2.0GT.
The Legacy Blitzen of December 2004 is the special edition based on the 2.0GT B4 and Touring Wagon. These high-performance sports models came with special colour bright red, sports suspension, 18-inch alloys, unique grille, and aero-style bumpers.
Based on the Legacy 2.0GT spec.B B4 and Touring Wagon, the WR-Limited 2004 was released in July 2004, and the 2.0GT-based WR-Limited 2005 was launched in August 2005. The WR-Limited models were painted in WR Blue Mica, and came with Gold alloy wheels, front under spoiler, special blue and black seats, and special emblems.

The Japanese Legacy received a cosmetic update in May 2006; Notable changes included new bumpers, headlights, front fenders, grille, and rear combination lamps. This facelift trickled down to export models in 2008.
Although model grades remained largely unchanged, the number of option packages available for certain grades reduced. The base model 2.0i Touring Wagon could also be ordered as the Casual Selection model. Urban Selection models were added to the 2.0R, 2.0GT, and 2.0GT SI-Cruise. The 2.0R was also offered as B-Sports Limited version.
On 2008-05-08, Subaru announced the EyeSight models for Japanese market. It consists of 2 cameras with one on each side of the rear-view mirror, that use human like stereoscopic vision to judge distances and generally keep tabs on the driver. The system can help you keep your distance on the highway, a lane departure warning system, a wake up call should everyone pull away from the lights but you, and even keeps an eye out for pedestrians. SI-Cruise has been integrated into the EyeSight feature as a driver safety aid. EyeSight was a new brand name for a safety system Subaru had previously introduced in Japan only in the 1999 Subaru Lancaster (Outback) called Active Driving Assist (ADA)
EyeSight models were available for Touring Wagon 2.0GT and 3.0R, B4 3.0R, Outback 3.0R. All EyeSight models include Sportshift E-5AT transmission.

It marked the return of a turbocharged engine to North American Legacy, featuring a 2.5-liter unit derived from that of the North American Impreza WRX STI. Due to advancements in turbocharger technology and tightening emission standards, the twin-turbo setup was dropped from the lineup. Turbocharged models and the H6 offered Subaru's first 5-speed automatic transmission, featuring SportShift technology licensed from Prodrive, Ltd.

The wagon body shared the roof sheet metal with the Outback model that had raised metal "humps" under the roof rails, unlike the Japanese and European wagons that had a sleeker roof. Another difference from other overseas markets, was that both sedan and wagon had longer front and rear bumpers, designed to meet the Canadian 5-mph bumper specification.
For 2006, the regular GT was dropped, and the 2.5i Special Edition was added into the line up. Manual transmission is also discontinued in station wagon body. Priced between the base and the Limited models, the 2.5i Special Edition came with power moonroof and power driver seat, while the 2.5i Limited also came with leather interior, power front passenger seat, and climate control automatic air condition.

October 22, 2003, with the debut of the third-generation Legacy at the 60th Frankfurt Auto Show, the Outback name is now being used in all markets with the launch of the third-generation Outback wagon, in order to rationalize the name Outback, which prior to then had only been used in export markets. Models equipped with a 3.0 L H6 were introduced at the 2004 Chicago Auto Show. The ground clearance is 8.5 in (220 mm).
The Outback carries the same model codes as the Legacy Wagon, BP9 for the 2.5 liter, and BPE for the 3.0-liter model. The highest trim level offered in the USA is the Outback L.L. Bean that offers optional equipment as standard, including wood and leather steering wheel, an auxiliary port on the stereo for MP3 player compatibility, perforated leather seats, GPS navigation, double sized, one piece, glass moonroof and the H6. Starting with this generation, the interior retractable rear cargo cover has a separate storage compartment in the spare tire storage area so that the cargo cover can be removed for large items but stored inside the vehicle and out of the way.
A new Outback variant for 2005+ is the Outback XT. This model comes with Subaru's turbocharged 2.5L 4-cylinder engine found in the Impreza WRX model. This engine produces 243 hp (181 kW), which is much higher than the naturally aspirated 2.5L producing 175 hp (130 kW).

Subaru beefed up their AWD 4EAT transmission's design and released the 5EAT w/ SportShift in 2005 The Outback received styling revisions for the 2008 model year, notably an enlarged, chrome-ringed grille. As of the 2008 model year, the Legacy wagon and Outback sedan were discontinued in the United States, leaving the Legacy sedan and Outback wagon. The JDM and EU diesel model has a "Start/Stop" button (in the top-of-the-line-model), found in Lexus, Infiniti, Audi and other high end makers.
For 2008, the 2.5i USA model has been certified PZEV emissions, and a badge has been attached to the rear of the vehicle on the bottom right hand side of the tailgate. All other models are certified LEV2. The PZEV Outback is available for sale in all 50 states, unlike other manufacturers who only sell PZEV certified vehicles in states that have adopted California emission standards.
Starting May 2008, the Japanese-spec Legacy could be fitted with a new safety feature called EyeSight. It consists of two cameras, one on each side of the rear-view mirror, that use human-like stereoscopic vision to judge distances and generally keep tabs on the driver. The system helps maintain a safe distance on the highway, warns the driver during unintended lane departure, emits a wake up call should everyone else pull away from the traffic lights, and keeps an eye out for pedestrians. SI-Cruise has been integrated into the EyeSight feature as a driver safety aid.
The Subaru EE series flat-4 diesel engine is offered in both Legacy and Outback models in Europe exclusively. Identified as the Subaru Outback 2.0D, the vehicle was released March 2008. The vehicle is offered with a 5-speed manual transmission only. The official introduction of the Legacy and Outback diesel was at the Geneva Motor Show in March, 2008.
