2.8L V6
The 2.8L V6 was introduced for the 1985 model year and was used in performance-oriented Fiero models including the GT, SE, and Formula.
The Fiero 2.8L V6 was part of GM's 60-degree V6 engine family rather than a Fiero-only engine. It was adapted for the Fiero's transverse mid-engine layout and used multi-port fuel injection.
