1991 WS6 Formula
1991 Formula production numbers 5,490.
New, more aerodynamic front and rear fascias were standard. The Formula still wore its cowl bulged hood, Formula decals, and the rear "Aero Spoiler". The "Aero Spoiler" received a change, its appearance was sleeker. The 91's & 92's were the only years that the Formula was available with a different wheel than the "turbo" snowflake style wheel. The Formula remained unchanged from 1991 to 1992, which was the last year of production of GM's 3rdGen F-body
No Formula was ever produced with a engine displacing less than 5 liters and 8 cylinders. No V6 Formulas were ever produced and the V6 motor could not be chosen for credit. If you wanted a Forumula, then you had to work for it by checking off boxes on the RPO codes and building your own Formula. All L98 cars received N10 dual cats standard.
