Seville Cadillac Moels & History 1979

Carried over with only modest trim changes, Sevilles got a retuned suspension to improve their ride, plus new body mounts.

  • Nameplates moved from the upper right of the grille to the upper left, and that grille had a tighter pattern than before.
  • The grille’s pattern of vertical crosshatch slots was repeated in twin insets in the front bumper.
  • Standard engine remained the 350 cu. in. (5.7-liter) V-8 with electronic fuel injection, now rated 170 horsepower.
  • The diesel version introduced at mid-year was offered again.
  • Sevilles destined for California received the three-way catalytic converter with closed-loop electronic controls, previously used only on other GM models.
  • Bodies could have 14 standard colors, with seven Firemist colors available.
  • Interiors came with new solid and striped Dante and Roma knit fabrics in six colors, or 11 shades of Sierra Grain leather.
  • Either the Tuxedo Grain padded vinyl roof (in 17 colors, including metallics) or a plain metal top were offered at the same price.
  • Options included the new digital trip computer and signal-seeking radios.
  • Cadillac’s catalog claimed that Seville had been chosen “one of the ten most beautifully designed production cars of the last 50 years.”
  • The special edition Elegante came in two-tone Slate Firemist and Sable Black, with accent striping and full-length side moldings with etched black grooving, plus a painted metal roof.
  • Elegante was identified by a Cadillac wreath and crest as well as script nameplate.
  • Standard were chrome-plated wire wheels with long-laced spokes.
  • Seating areas and door panels had perforated leather inserts with suede-like vinyl trim, with leather-trimmed steering wheel.
  • The Dual Comfort 40/40 seats had storage pockets and an integral fold-down center armrest.
  • New for 1979 was plush fur-like Tangier carpeting.
  • Elegante’s price tag was $2735.
