The 1991 model year
Overview
The four-cylinder finally got serious attention: a twin-spark-plug (dual-plug) 2.3 raised its rating to 105 hp. The 5.0 V8 carried over at 225 hp but now wore new 16-inch five-spoke alloy wheels with directional 'pizza-cutter' styling. This was the first year a base Mustang crossed $10,000. (Horsepower figures are SAE net.)

Year over year
What changed

Living with it
Reliability & ownership notes
- The dual-plug 2.3 is smoother and a bit stronger than the earlier four.
- Same durable 225-hp mass-air 5.0.
- Inspect for Fox-body rust; sales were declining and some cars saw hard use.
Worth knowing
Notable
- The '5-lug' marketing aside, these remained four-lug cars; the new 16-inch five-spoke wheels are the visual marker of 1991–93 V8s.
