2004 Honda Odyssey vs 2005 Honda Odyssey Comparison
The Honda Odyssey has long served as the benchmark for family transport, but the transition between the 2004 and 2005 model years marked a significant shift in design philosophy. The 2004 Odyssey concludes the second-generation platform, known for its proven J35 engine and straightforward utility. Conversely, the 2005 Odyssey launched the third generation, introducing a wider track, sharper styling, and significant advancements in powertrain efficiency and interior ergonomics.
Design and Ergonomic Evolution
The 2004 Odyssey features a more traditional, boxy aesthetic that maximizes interior volume relative to its footprint. Its interior layout is functional, featuring the iconic "Magic Seat" that folds flat into the floor. However, the materials and cabin noise levels reflect early 2000s standards.
In contrast, the 2005 Odyssey adopted a more aggressive, aerodynamic exterior. The interior received a complete overhaul, with higher-quality plastics, improved sound deadening, and the introduction of the "Plus-One" second-row seat, which allows for an eight-passenger configuration. The 2005 model also moved the gear shifter to the dashboard, freeing up space in the center console area. β MINI Of Portland Vs. Nationwide MINI Dealership Experience
Performance and Mechanical Reliability
Under the hood, the 2004 Odyssey utilizes a 3.5L V6 producing 240 horsepower. While capable, it is paired with a transmission that has been subject to well-documented longevity concerns in early second-generation models. Prospective buyers should verify if the transmission fluid has been changed regularly or if the unit has been replaced. β Western Pacific Building Materials
The 2005 Odyssey increased output to 255 horsepower and featured a more robust five-speed automatic transmission. This generation also introduced Variable Cylinder Management (VCM) on specific trims like the EX-L and Touring, which improves highway fuel economy by deactivating three cylinders during light-load cruising. While VCM can lead to oil consumption issues in high-mileage examples, the overall driving dynamics of the 2005 model are objectively superior.
Value and Market Depreciation
According to Kelley Blue Book data, the 2004 Odyssey has largely bottomed out in terms of depreciation, making it an excellent choice for those needing a reliable people-mover on a strict budget. The 2005 model, being newer and more feature-rich, commands a higher price point in the used market.
When evaluating a 2005 Honda Odyssey EX-L for sale, such as units found in Oakland, CA, expect to pay a premium for the added safety features like side-curtain airbags and electronic stability control, which were not standard on all 2004 trims.
