📚 Vehicle History

Subaru Focus:

Subaru is known for its Symmetrical All-Wheel Drive system and horizontally-opposed boxer engines, though the Dex was an exception, being a badge-engineered model.

Dex Development:

The Subaru Dex was a compact MPV (Multi-Purpose Vehicle) or tall hatchback, based on the second-generation Toyota bB (internally designated as the Toyota C-platform, specifically the J4 chassis). It was developed as part of a collaboration agreement between Toyota and Subaru.
