📚 Vehicle History

Brand Heritage:

Subaru, a division of Subaru Corporation (formerly Fuji Heavy Industries), has a long history of producing vehicles known for their Symmetrical All-Wheel Drive systems and horizontally opposed 'boxer' engines. This engineering philosophy often results in enhanced stability, handling, and traction in various driving conditions.

Model Evolution:

The B9 Tribeca was Subaru's first foray into the mid-size, three-row crossover SUV segment. Introduced for the 2006 model year, it featured a distinctive design, including Subaru's controversial 'nose cone' grille, and was built on a platform shared with other Subaru models. It received minor updates for 2008, including a refresh of the grille and interior enhancements, and was renamed simply 'Tribeca' starting with the 2008 model year in some markets, dropping the 'B9' designation.

Production Location:

Lafayette, Indiana, USA (Subaru of Indiana Automotive, Inc. - SIA)

Total Production Run:

Production was discontinued after the 2014 model year due to slow sales.

🏆 Awards & Recognition

Recognitions:

While the B9 Tribeca did not receive widespread major awards, it was praised by some reviewers for its comfortable ride and capable AWD system. Its design was polarizing, and sales figures did not reflect significant market acclaim compared to its competitors.
