What year is the 4th gen Subaru Legacy?
The fourth-generation Subaru Legacy spans model years 2003 through 2009.
In practice, this means any Legacy built for the 2003, 2004, 2005, 2006, 2007, 2008, or 2009 model year belongs to the fourth generation. Subaru introduced this generation in 2003 with a redesigned platform and styling, and it continued until the 2010 model year when the fifth generation arrived.
Overview of the fourth generation
The fourth-generation Legacy brought a more modern silhouette, refreshed interior, and Subaru's hallmark all-wheel-drive capability across most trims. The lineup offered a range of engines and configurations to suit different markets, including naturally aspirated and, in certain trims and regions, turbocharged options. It also featured styling updates and a mid-generation refresh to boost interior materials, technology, and safety equipment.
- The generation spans model years 2003–2009 in most markets.
- Engine options commonly included a 2.5-liter flat-four, with higher trims and certain markets offering additional powertrains such as turbocharged or larger flat-six variants.
- All-wheel drive remained a core feature across most versions, reinforcing Subaru’s trademark capability.
- Styling and interior refinements were part of a mid-generation refresh to improve comfort and tech.
These years mark Subaru's transition to the fifth generation in 2010, as the Legacy lineup moved on to a new generation with different platform architecture and styling.
Variants and market differences
Within the 4th generation, trim levels and engine choices varied by region. In some markets, more performance-oriented or premium trims offered additional powertrains and upgraded equipment, while entry-level trims remained focused on efficiency and value.
Transition to the next generation
Subaru introduced the fifth generation in 2010, marking the end of the 4th generation's lifecycle and the start of a new platform and design direction for the Legacy lineup.
Summary
The 4th generation Legacy spans model years 2003–2009, delivering improved design, refinement, and all-wheel-drive capability—before Subaru moved on to the fifth generation in 2010.
