Engine Options:
* 2.5L Iron Duke Inline-4: This was the base engine. It was a relatively low-powered engine known for its reliability but not its performance.
* Horsepower: Around 78-84 hp (sources vary slightly depending on the exact model and configuration)
* Torque: Around 100 lb-ft
* Fuel Economy: Generally decent fuel economy for the time, though exact figures are hard to pin down without specifying the transmission. Expect mid-20s MPG on the highway.
* 2.8L V6: This was the optional engine and offered considerably more power.
* Horsepower: Around 140 hp
* Torque: Around 160 lb-ft
* Fuel Economy: Lower fuel economy than the 4-cylinder, likely in the low 20s MPG on the highway.
Stock Performance (Approximate):
The performance figures are again highly dependent on the engine and transmission:
* 0-60 mph: The 2.5L 4-cylinder model would likely take around 12-15 seconds to reach 60 mph. The 2.8L V6 would be considerably quicker, probably in the 8-10 second range.
* Top Speed: Top speed for the 4-cylinder would be around 90-100 mph, while the V6 could reach around 115-125 mph. These are estimates, and actual top speeds would be influenced by wind resistance, road conditions, and other factors.
* Handling: The Fiero, particularly the V6 model, was surprisingly nimble and fun to drive for its time. Its low center of gravity contributed to good handling characteristics. However, it wasn't known for exceptional grip.
Important Notes:
* Transmission: The transmission (manual or automatic) would significantly affect acceleration and fuel economy. Automatic transmissions generally resulted in slower 0-60 times and slightly lower fuel economy than their manual counterparts.
* Condition: The performance of a specific 1985 Fiero will depend heavily on its condition and maintenance. A well-maintained example will perform better than a neglected one.
* Variations: There were slight variations in horsepower and torque figures across different years and even within the same year depending on options and factory variations. The numbers above represent approximate ranges.
For precise numbers for a particular 1985 Fiero, you would need to consult factory specifications from that year or look for specific testing data on that model. Finding original brochures online might provide more exact figures.
