Story
1986 Pontiac Fiero
The 1986 Fiero line included the notchback Coupe and Sport Coupe, the aero-body notchback SE, and the new fastback GT. They share one two-seat, rear-mid-engine model-year family page. The fastback roof, an SE aero body, a V6, or a GT badge is a configuration clue, not enough by itself to authenticate one car.
Four-cylinder and V6 power
The 92-hp 2.5-liter Tech IV four was standard in the Coupe, Sport Coupe, and SE. The 140-hp 2.8-liter multi-port-injected V6 was optional in the SE and standard in the GT. Four-cylinder cars used the Isuzu five-speed. Early V6 cars retained the Muncie four-speed; Pontiac replaced it with the Muncie-built Getrag five-speed in June 1986. The THM125C three-speed automatic remained the automatic path where listed.
Independent chassis and four-wheel discs
Every Fiero used a welded steel space frame, nonstructural Enduraflex body panels, independent front and rear suspension, manual rack-and-pinion steering, and power-assisted four-wheel disc brakes. The SE used Y99 Rally Tuned suspension. The GT combined WS6 suspension, 19.2:1 steering, 15 x 7-inch diamond-spoke wheels, P205/60R15 front tires, and P215/60R15 rear tires.
Bodies, colors, production, and proof
The Coupe and Sport Coupe retained the 160.7-inch notchback shape. The 165.1-inch SE used the previous GT's aero body, while the delayed 165.2-inch GT introduced new fastback rear quarters, quarter windows, deck, grilles, lamps, and fascia. Five exterior colors and four reconciled series rows account for 83,974 cars. Authenticating one survivor still requires its VIN, service-parts label, space frame, drivetrain, chassis, protected finishes, cabin, component dates, recall history, and ownership records.
