1988 Mercury Cougar XR-7

The 1988 model year proved to be a great one for the Cougar.

For its final year on the Fox chassis, Ford dialed in a few tweaks for the 1988 Mercury Cougar. While there were no major changes anywhere on the vehicle, enough updates were made to qualify this as more than a carryover year. Ford confirmed that 1989 would bring about an all-new Cougar on a brand new chassis, so dealers expected higher volume in the showrooms—and they were correct. The 1988 model year proved to be a great one for the Cougar as sales soared.

Cougar XR-7

The 1988 Cougar XR-7 was perhaps the most recognizable of all aero Cougar models.

The 1988 Cougar XR-7 now featured a striking new monochromatic paint scheme, available only in Oxford White, Medium Scarlet or Black. The car featured body-colored side moldings, grille and outside mirrors; blacked-out window trim; black door handles and key surrounds; and body-colored 15″ aluminum wheels that came from the new 1987 Mustang GT (argent wheels were optional on the XR-7). Interestingly, there were no special “XR-7″ C-pillar emblems, but the standard LS emblems instead. And there was special pinstriping for the XR-7, a decal that rode above the upper shoulder line and terminated at the grille. The 1988 Cougar XR-7 was perhaps the most recognizable of all Cougar models from 1983 to 1988 and continues to be desirable even today.

Mechanically the XR-7 received an 8.8″ rear differential and standard 10″ drum brakes. It is believed to be the only factory Cougar from 1983-88 to have the larger 8.8″ rear axle, as all had been 7.5” up to this point. No other significant suspension changes were made. The standard 5.0L V8 engine also had no internal power increase but the addition of a split dual exhaust bumped up the car’s total horsepower output by 5 ponies, for a total of 155hp. Once again the only transmission was the 4-speed AOD overdrive transmission.


The XR-7’s front end featured the aforementioned striping and body-colored grille.


While the standard body-colored wheels certainly made a statement, the optional argent wheels really made the car’s color pop.


The big news for the XR-7’s interior was the return of the standard analog gauge cluster, absent since 1986. A V8-spec tachometer was the only change from the last version. Also, the sport steering wheel, shown here, became standard. The full electronic instrument cluster was still an option for the XR-7 as well as the LS.

Cougar LS

While the Cougar LS model was physically identical to the previous model year, save for color choices, there were changes to the engines. The base 3.8L V6 got an internal balance shaft and a new multiport fuel injection system for smoother operation and greatly improved throttle response. Power was now rated at 140hp and now the V6 definitely felt more powerful and responsive than its CFI predecessor. Fuel economy was bumped up slightly as a result. As with the XR-7 model, the 5.0L V8 received a new quasi-dual exhaust for a total of 155hp.

Smart Cougar buyers could order a fully-loaded LS model with the V8 and have a virtual XR-7 clone.

Because auto insurance in America was such an expensive and tricky prospect in the 1980s, the idea of shelling out almost U.S. $20,000 (or more) for an XR-7 model and then insuring it at full value was, as you may guess, not cheap. The trouble was that, even though the XR-7 had a standard-output V8 and not the performance-oriented HO 5.0 from the Mustang, it was still considered a “sports” or “performance” model, thereby bumping up insurance premiums. However, smart Cougar buyers could order a fully-loaded LS model with the V8 and have a virtual XR-7 clone, save for the paint scheme and wheels, and enjoy lower insurance rates. This proved to be a popular move for many buyers as the used market for 1988 Cougars routinely shows a plethora of V8 cars.


The LS interior was virtually unchanged from the previous year.

The 1988 3.8L V6 featured an all-new intake plenum, multiport fuel injection, lower intake, cylinder heads, valve covers, accessories and brackets, and air intake for a total of 140hp. The V6 started to strongly resemble the 5.0L V8 in layout and looks, and a few parts were even shared between the engine bays.

The 5.0L V8 (standard in XR-7, optional for LS) did not receive internal upgrades but the standard dual split-Y exhaust gained the car an overall output of 155hp.

Rear seat passengers had their own center-mounted armrest for comfort.

Sales picked up nicely for the Cougar in 1988, and as the chapter on the sixth-generation Cougar closed, the car proved to be durable, reliable and dependable, and a great value for the money. Lincoln-Mercury dealers knew that the Cougar was a solid bet and they looked forward to the debut of the MN12-chassis car to further their sales goals.

The era of the Fox-chassis 1983-88 Mercury Cougar proved to be a very popular one. Not only did sales soar upwards throughout this six-model-year period, but the age of the “aero” car was now in full swing, as other automakers scrambled to copy Ford’s look on their automobiles. Where competing GM gave up the rear-drive segment to go front drive (Grand Prix, Cutlass, Regal, Lumina), and aero-look clones appeared (Chrysler LeBaron), Ford had a virtual lock in the midsize rear-drive luxury coupe market. The aero Mercury Cougar was, quite simply, the right car at the right time.
