Background & Details

This is getting boring to say but there are really no major changes to the Mustang again this year. Increases in pricing, a few choices in wheels and trim. Floor mats and a cargo tie down option. Blah, blah blah.

About the most exciting change was that the entry-level Mustangs received some much needed engine improvements for 1991. The 2.3 liter four cylinder got new twin-plug cylinder head and distributor-less ignition which increase power from 88 horsepower to 105 horsepower. The big reason to make the improvements was more for emission reduction than getting more power, but hey we will take it.

Other changes in 1991 included new five-spoke 16-inch cast aluminum wheels that replaced the 15 inch wheels of previous years for all the V8 powered cars. Convertible cars now had a power top that folded closer to the body for a neater appearance, and automatic-transmission cars met yet another new federal edict by adding an interlock that required pushing the brake pedal before the shifter would move out of Park.

LX 5.0s switched from rough-riding Goodyear Eagle GT+4 tires to more compliant 225/55ZR16 all-season Michelins. GTs retained the unidirectional Goodyears in that same size but offered the Michelins as a no-cost alternative.
