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 faldaway 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.
