Cadillac Allante Models & History 1993

Allante 1993

The redesigned 1993 Allante convertible (no longer offered in convertible hardtop configuration) was an early-1992 launch.

  • This early debut also introduced the world to the Northstar V-8 engine, which now powered the Allante, replacing the 4.5-liter V-8 formerly used.
  • As with all other Northstar applications, the 4.6-liter V-8 was paired with the 4T80-E electronically controlled four-speed automatic transmission.
  • The Northstar debut featured highly efficient compound-geometry valve/port designs and “quiet coil” Direct Ignition System designed to operate at high rpm levels without loss of spark synchronization.
  • The engine’s dual stream injector Fluid Induction System was another innovation. This system was isolated from underhood heat sources and cooled the fuel during operation, which enhanced performance.
  • The 4T80-E transmission featured a controlled-flow, dual lubricating system that provided proper lubrication under all operating conditions. Free-wheeling clutches ensured consistent shifting quality.
  • In its final year of production, the Allante was vastly upgraded with the addition of road sensing suspension, speed sensitive steering and the new-generation Bosch ASRIIU traction control system.
  • The convertible also benefitted from receiving the short/long arm (SLA) rear suspension that improved steering responsiveness.
  • Other new standard features of the Allante included revised 16-inch cast aluminum wheels fitted with Goodyear Eagle GA P225/60ZR16 tires and a 23-gallon polyethylene fuel tank.
  • Chrome wheels were a new option.
  • Outside, a new maroon color soft top was offered and the removal aluminum hardtop remained available as an option.
  • A new three-inch front fascia spoiler enhanced high-speed aerodynamics while new, one-piece side window glass improved weather sealing and acoustics.
  • Three new clearcoat paint colors were offered: Pearl Red, Pearl Flax, and Palo Green — upping the total to eight colors available.
  • Allante also featured a headlamp washer system, new outside electric heated rearview mirrors with a foldaway design, and blue-tinted glass.
  • New Nuance leather-trimmed bucket seats were orthopedically designed to provide optimal support and comfort. The seats had power eight way metaphoric adjustments and a new four-way power lumbar control.
  • The console included a transmission shift selector that was slightly offset 20 degrees toward the driver for ease of shifting.
  • Allante also featured the new Pass-Key II anti-theft system as a standard item.


The 1993 Cadillac had a 17-symbol vehicle identification number (VIN) stamped on a metal tag attached to the upper left surface of the cowl visible through the windshield. The digits of the code were as follows:

  • First digit = “1” = manufacturing country (United States)
  • Second = “G” = General Motors
  • Third = “6” = Cadillac
  • Fourth & fifth = car line/series
    • V/S = Allante convertible
  • Sixth = the body style: 5 = four-door sedan
  • Seventh = the restraint code:
    • 1 = active (manual) belts
    • 2 = active (manual) belts w/dual airbags
    • 3 = active (manual) belts w/driver’s side airbag
    • 4 = passive (automatic) belts
    • 5 = passive (automatic) belts w/driver’s side airbag
  • Eighth = the engine:
    • Y = LD8 4.6L V-8
    • 9 = L37 4.6L V-8
  • Ninth = check digit
  • 10th = model year, “P” for 1993
  • 11th = the assembly plant
  • The remaining six digits identify the production sequence number
