Technical identity
The engineering at a glance.
This first expansion records museum-level specifications rather than pretending every year and market used one immutable specification.

Research starting point
Built to improve, not freeze.
Model-year specifications can vary. The museum keeps the stable historical interpretation here and leaves room to add exact variants, racing derivatives, engine codes and source-specific specifications later.
