Story

1985 Pontiac Fiero

The 1985 Fiero remained Pontiac's two-seat, rear-mid-engine sports car, now in four series: Coupe, Sport Coupe, SE, and GT. The new GT used the aero body developed from the 1984 Indy replica but retained the original notchback roof. The fastback GT belongs to later model years.

Four-cylinder and V6 choices

The improved 2.5-liter four kept its 92-hp rating while adding roller valve lifters and paired with the new Isuzu five-speed manual. The new 140-hp 2.8-liter V6 used multi-port fuel injection, a four-speed manual, and dual-outlet exhaust. The Canadian factory brochure offered the V6 in the Sport Coupe and SE as well as making it standard in the GT; the period history narrows that optional application to SE, so an individual Sport Coupe needs decisive RPO and build evidence. A three-speed automatic was available with either engine where the factory selector permitted.

Independent suspension and four-wheel discs

Every Fiero used independent suspension, manual rack-and-pinion steering, and power-assisted four-wheel disc brakes. The SE carried Y99 Rally Tuned suspension, while the GT used WS6 with quick-ratio steering, tuned springs and dampers, 14-inch Hi-Tech wheels, and P215/60R14 tires. The 1988 suspension redesign is not original 1985 equipment.

Body, cabin, production, and proof

The Coupe, Sport Coupe, and SE shared the 160.7-inch notchback body; the GT's aero fascias and skirts extended overall length to 165.8 inches. Two reclining buckets, a full console, headrest speakers, model-specific instruments, four exterior colors, and optional comfort equipment shaped the cabin. Period tables reconcile 76,371 cars across all four series and list each base price, but no reviewed ledger divides them by engine, transaxle, suspension, color, trim, option, build date, export, or surviving-car status.

Still Researching

production The 76,371 total and four series rows reconcile, but no reviewed audited Pontiac ledger resolves engine, transaxle, Y99, WS6, paint, trim, option, plant, build date, export, recall completion, or survivor counts.
paint colors Four exterior colors and codes are documented, but no complete reviewed selector resolves every series, lower accent, trim, panel-replacement, supplier, special-order, and build-date combination.
interior Factory literature documents seating, instruments, controls, major trim paths, and options but not every upholstery code, material, exterior-color pairing, supplier, series, option, and running change.
authenticity markers Public model-year references cannot establish one survivor's born-with space frame, panels, engine, transaxle, chassis, finish, cabin, options, component dates, or campaign completion; the primary brochure and period history also conflict on optional V6 Sport Coupe availability.
