Fiero

Pontiac Fiero

The Pontiac Fiero began life inside General Motors as an idea that had almost nothing to do with sports cars. Chief engineer Hulki Aldikacti's two-seat, mid-engine proposal impressed GM's Engineering Policy Group when he showed up with a running prototype in April 1980, but by the time the corporation formally approved the car for production in May 1982, it had been reframed internally as a fuel-efficient commuter vehicle rather than a performance model, a positioning that, by several accounts, was as much about protecting the Corvette's turf within GM as it was about fuel economy in the wake of the gas crises of the era. That compromise shaped the car from the start: Fiero got a proprietary body and chassis but was built around parts-bin mechanicals, including a suspension borrowed largely from other GM economy cars rather than the purpose-built setup engineers had originally wanted.

Production began around August 1983 for the 1984 model year, and the Fiero that reached showrooms was genuinely unusual for a mainstream American manufacturer: a transverse mid-engine, rear-drive two-seater with a steel spaceframe chassis wearing composite, dent-resistant 'Enduraflex' body panels. The only engine offered that first year was the 2.5-liter 'Iron Duke' four-cylinder, rated at 92 horsepower. It was durable, but hardly quick, and a poor match for the car's sports-car looks and handling. Even so, the Fiero was a sales hit out of the gate, with 1984 production running into six figures.

That strong start was badly undercut by a defect that would define the Fiero's early reputation: engine compartment fires, concentrated heavily in 1984 four-cylinder cars. The root cause was a combination of problems rather than one single flaw. GM had specified a reduced three-quart oil capacity for the engine but left the dipstick calibrated for the old capacity, so an engine that was actually a quart low would still read as full. Compounding that, a share of the Iron Duke connecting rods (reportedly as much as 10 to 40 percent in some batches, according to an internal Pontiac memo) were weakened by casting problems at GM's Saginaw foundry. When oil ran low, a weak rod could fail, punching through the block wall and spilling hot oil onto the exhaust manifold, where it could ignite. GM did not act quickly: it took until November 1987, the evening before Thanksgiving, for the company to issue a formal recall covering more than 136,000 1984-model Fieros (about 125,000 of them in the US), install a larger oil filter and pan to raise capacity to four quarts, fit a corrected dipstick, and reimburse owners for related repair costs they'd already paid out of pocket. Accounts of how many fires occurred differ: one puts GM's own tally at 112 reports received through the end of 1985, mostly on 1984 cars, while other retrospectives cite a broader estimate of 260 to 300 total incidents. The two figures may reflect different time windows or counting methods.

While the recall crisis played out in public, the car itself kept evolving. For 1985, Pontiac added a 2.8-liter V6 rated at 140 horsepower, offered alongside the four-cylinder on SE and new GT trims, with the GT adding firmer suspension tuning and wider tires on the same notchback body used since 1984. The GT was restyled for 1986 with a fastback 'flying buttress' roofline and revised rear bodywork, distinguishing it visually from the continuing notchback base and SE cars; that fastback GT carried on with only minor updates through 1987, such as a larger fuel tank.

The Fiero's final and, by most enthusiast and specialist-press accounts, best model year was 1988. Pontiac gave the car a substantially reworked suspension and revised spaceframe elements, along with improved two-piece brake calipers and upgraded rotors. The changes were good enough that a persistent myth credited them to Lotus, which GM was in the process of acquiring, though most sources say the redesign was actually developed in-house by Pontiac's own engineers drawing on what they'd learned racing the car. 1988 also brought a new Formula trim, which combined the lighter notchback body with the GT's V6 drivetrain and the new suspension, while the SE trim was dropped, leaving base, GT, and Formula as the lineup.

None of that mattered enough to save the car. GM ended Fiero production partway through the 1988 model year, officially citing a steep sales decline (from 136,840 units in the Fiero's 1984 debut year down to just 26,402 in its truncated final year) after total production across the model's life reached 370,168 units. Some accounts add a sharper edge to the story: that a more powerful and reportedly cheaper next-generation Fiero, said to be in development with a DOHC V6 producing well over 230 horsepower, was seen inside GM as a threat to the Corvette's market position and was killed along with the car it would have replaced. Whatever the full mix of reasons, the Fiero was canceled just as it had finally become the sports car it was originally imagined to be.
