1991 Ford Mustang Specs & Details

1991 was another carryover year for the Mustang, so things were a snoozefest. For the first time, annual Mustang sales dipped below 100,000, and about the only ones paying attention were nervous Ford executives. Undoubtedly, the appearance of sophisticated Japanese sport coupes like the Mitsubishi 3000GT and Toyota Supra were taking their toll on the market. Yet, a new Mustang was still a few years away.

And you know things are mundane when the most significant mechanical changes are to the base four-cylinder engine. At long last, the always-there 2.3-liter powerplant gets an upgrade. Thanks to a new eight-sparkplug setup, reworked intake, and distributor-less ignition, the four-banger is bumped to 105 horsepower and 140 lb-ft of torque (from 89 horsepower and 120 lb-ft of torque). It’s no 5.0, but every little bit helps.

The Mustang GT-lite, or more accurately the LX 5.0L, continues with GT mechanicals hidden inside the body of a base Mustang. The 5.0-liter V-8 still cranks out 225 horsepower and 300 lb-ft of torque, while the gas-pressurized front struts and rear Quadra-Shock setup keeps the LX 5.0L manageable on the street. Handling is also improved due to new all-season radials covering new-for-1991 five-spoke 16-inch wheels (the GT also gets this wheel and tire upgrade).

The GT is available with titanium-colored lower accent trim, which continues through 1993. So, this design upgrade offers a convenient visual clue for identifying late-model Fox Body GTs. The GT convertible (as well as the other Mustang soft tops) gets a new power top that creates a lower-profile hump when folded. Otherwise, the 1991 Mustang looks no different from the previous year.

Colorwise, last year’s Race Yellow was dropped without a replacement. That means if you wanted a bold-toned Mustang, you had to go red (Medium Red or Bright Red), and the Wild Strawberry Clearcoat Metallic wasn’t so wild; it was just a darker red. Although, the Bright Green Calypso sure got noticed.

1991 also sees even the cheapest Mustang costing more than $10,000 ($10,702, precisely). And despite the premium for a convertible (starting at $16,767), soft-tops outsold the notchback coupe (21,513 vs. 19,447). But, as it had been for years, the three-door hatchback continued to be the best-selling body style (57,777). The most expensive Mustang, the GT convertible, stickered at $20,409. But for many, the sweet spot was the notchback LX 5.0L which started at $13,815. For this, you got the GT’s powerplant and suspension as well as air conditioning, sport seats, and the sound system upgrade.
