Short for 2 seat, mid-engine, 4 cylinder, the Fiero 2m4 debuted in 1984, and was produced through the 1988 model year. The Pontiac Fiero was introduced as an economical commuter, and therefore the “iron duke” four-cylinder engine was always the staple of the line-up. The 2m4 could be had with either an automatic transmission or a manual shift, and certain options could be ordered as well. It ws devoid of any type of body cladding or ground effects, and sported a luggage rack on the rear deck rather than a spoiler. Overall, the 2m4 was an excellent commuter vehicle, and is what is most commonly associated with the Pontiac Fiero.
Notice the 1984 only magnesium grill insert. Later models changed to the more familiar side-mounted grills for better cooling and ventilation of the battery compartment.
