Category:Chassis families

This category contains basic chassis families/platforms as identified in service manuals.

Unlike the chassis number on the rating label (e.g., "A118"), which identifies a specific production variant, a chassis family (e.g., "GJ") represents the overall design platform shared by multiple models.

Relationship

• Chassis family (service manual): The internal engineering platform name used for documentation, schematics, and parts organization. Stable across a product generation.
• Chassis number (rating label): The manufacturing/compliance identifier for specific hardware builds, which may change with board revisions, component substitutions, or factory variants.
