1978 Ford Thunderbird: A Record Year and a Diamond Jubilee

This record's own dek states that 1978 was a record production year for Thunderbird, and that the Diamond Jubilee Edition marked Ford's 75th year; this record's own overview repeats that Wikipedia's seventh-generation table gives 352,751 Thunderbirds for 1978 across all bodies and engines, with no body, engine or option split found in a citable source, and this record's own production section carries that same 352,751 figure as its single row, labeled a whole-line total rather than a performance-configuration count. This record's own production notes state plainly that no citable split by body style, engine or option was found for the year, leaving that single row as this record's own only production figure for 1978.¹

This record's own overview also states that Wikipedia says the Diamond Jubilee Edition commemorated Ford's 75th year and brought the price to almost $12,000, though Wikipedia gives no production count for that edition; this record's own prices section instead gives the Diamond Jubilee Edition a tabulated $10,106, with a note that 18,994 of them were built and are already included in the 352,751 whole-line total rather than counted separately.^1,2

This record's own conflicts section formally weighs those two Diamond Jubilee figures against each other under the topic "Diamond Jubilee Edition price": Automotive Mileposts' precise $10,106 against Wikipedia's rounder, uncited "almost $12,000"; this record's own treatment note explains that the Automotive Mileposts figure leads because it is part of a self-consistent production-and-price table whose own 18,994-unit Diamond Jubilee count is the same one this record would use if a Diamond Jubilee production row were ever added, while Wikipedia's figure is kept as a conflict rather than discarded outright.^2,1

This record's own prices section also gives $5,411 for the base Thunderbird and $8,420 for the Town Landau, both dated to the 1978 model year's October 1977 introduction and tabulated by Automotive Mileposts from a 2009 Wayback-archived capture of its own production page rather than a contemporary source. A separate priceNotes field adds that this page once also carried a J.D. Power live-valuation figure, pulled from every page on the site on September 24, 2026 because those pages could change without notice and could not be independently checked, warning that a suspiciously exact price elsewhere may be quoting that same unconfirmed figure.²

This record's own overview also states that Wikipedia gives the seventh generation a 302 V-8 base engine with the 351M and 400 V-8s optional, the 400 dropped in a later year per Wikipedia's own generation-wide text, with no year-specific ratings given; this record's own engines section carries those same three entries by displacement and availability alone, each with an empty induction field and an empty ratings array. This record's own keyFacts, transmissions, performance, identification and unpublished-leads sections remain empty for the year.¹

This record's own paint section lists twenty codes from Automotive Mileposts' archived 1978 paint page, each with its Ditzler number. The page restricts several of them: 3E Diamond Blue Metallic and 5Y Ember Metallic to the Diamond Jubilee Edition, 83 Light Chamois to the Town Landau and Sports Decor Group, and Light Blue and the Bright Blue and Light Jade Glow colors away from the Town Landau; 1P Medium Gray Metallic and 2U Lipstick Red appear only as lower bodyside colors, on Silver Metallic and Polar White cars respectively.²

This record's own options section carries seventy-seven entries from the same site's archived optional-equipment page, at prices the site compiled from mixed dates and sources, many with a lower figure when ordered alongside another group. Among the items the page marks as new for 1978 are the $699 T-Roof Convertible, the $446 Sports Decor Group, a $45 power antenna and a $295 40-channel Citizen's Band radio; the Interior Luxury Group is listed at $783, the power moonroof at $691, and the 351 and 400 2V V-8s at $157 and $283.²

This record's own interiors section lists seventy-six trim codes from the archived interior-trim page, including four Diamond Jubilee Edition trims in Diamond Blue or Chamois luxury cloth or Ultra Soft Leather, the leather added late in the model year. The page prints HR for both the Russet and Jade striped-cloth buckets and TB for two Diamond Jubilee trims, so both pairs are recorded as printed with a note rather than corrected. This record's own specifications section adds the archived production page's 114.0-inch wheelbase, 215.5-inch length, 21.0-gallon tank, 57/43 weight distribution and listed weights of 4,082, 4,104 and 4,200 pounds, all from Automotive Mileposts rather than a factory document.^2,2
