The 1955 model year

Overview

Ford launched Thunderbird for 1955 as a two-seat personal car in body-model 40A soft-top and 40B removable-hardtop forms. The revised factory AMA specification lists one 292-cu-in V8 with a conventional three-speed manual, optional overdrive, or Fordomatic automatic across the Thunderbird range.

Year over year

What changed

  • Thunderbird debuted as a new Ford two-seater for 1955.
  • Ford assigned separate 40A and 40B body-model symbols to the soft-top and removable-hardtop cars.
  • The factory specification supports three transmission choices with the sole 292 V8.

Worth knowing

Notable

  • The removable hardtop is represented through Ford's 40B body-model symbol without inventing additional engine combinations.

Living with it

Reliability & ownership notes

  • Verify the 40A/40B body-model identity and installed transmission before ordering restoration or service parts.
  • Inspect frame and body corrosion, top hardware, cooling, braking, and electrical condition rather than assuming appearance establishes originality.
