For 1974, the Cougar was shifted from its Mustang, ponycar origins onto a new platform and into a new market as a personal luxury car. It now shared a chassis with the larger Mercury Montego/Ford Torino intermediates and was twinned up with the new Ford Elite. The wheelbase grew to 114 inches (2,896 mm) and became practically the only car to be upsized during the downsizing decade of the 1970s. These years marked the end of the “luxurious Mustang”, and the beginning of the Cougar’s move towards becoming a “junior Thunderbird” and eventually a sibling of the Thunderbird. TV commercials compared the Cougar to the Lincoln Continental Mark IV, the most notable featuring Farrah Fawcett in a 1975 TV ad.
The Cougar was being marketed as an intermediate-sized personal-luxury car to compete against GM’s Chevrolet Monte Carlo and Pontiac Grand Prix. Every GM division had an entry in this market by ’74 and the market was too large to ignore. The new Cougar paid homage to its smaller predecessor with a three-piece grille up front, topped by a new hood ornament which featured a side profile of a cougar’s head. This was a touch which would last until 1983. The car’s Montego heritage was fairly evident from the back, however. In between, it had acquired the sine qua non of the personal luxury car in the 1970s: opera windows. This body ran unchanged for three years, and during this period all Cougars were XR-7s.
The Cougar was also restyled inside due to the switch to the larger intermediate body but maintained the front fascia look from 1973 with a new styling feature including a rectangular opera window in the rear c-pillars. The Cougar also began to share the look of the Thunderbird and Continental Mark IV as the years progressed. The base model and convertible were dropped this year, but the XR-7 moniker soldiered on as the only model in the Cougar lineup.
Engine offerings from 1974 to 1976 included a standard 351 in³ V8 and optional power plants included the very rare Q-code 351 Cobra Jet V8(1974), plus 400 and 460 in³ V8s. The manual transmission was dropped in favor of the automatic.
Interior offerings during these three years included a standard bench seat with cloth or vinyl upholstery, an optional Twin-Comfort Lounge 60/40 bench seat with center armrest and cloth, vinyl or optional leather trim; or all-vinyl bucket seats with center console.
In 1975 the Cougar XR-7 continued to add more luxury features as it moved upscale. But with more features, the Cougar was gaining in weight as well. Compared to the 1967 version, the 1975 version weighed a full 1,000 lb (450 kg) more. Despite the added weight the buying public wanted the Cougar and sales figures reflected that fact. However for the performance fans, a high-performance rear axle and Traction-Lok differential continued to be on the option sheet. The standard engine continued to be the 148 hp (110 kW) 351 Windsor 2-barrel V8 with the 158 hp (118 kW) 400 2-barrel V8 and 216 hp (161 kW) 460 4-barrel V8 optional.
This Cougar entered its last year largely unchanged from 1975. There was a new body for the Cougar in 1977, so nothing else major was done to the Cougar this year. Only some minor trim pieces served to differentiate this year from last. Engines continued unchanged as well. The high performance axle and Traction-Lok differential were dropped this year. Twin Comfort Lounge reclining seats, with or without velour cloth trim, were the only major change for the interior, but it also showed how much the performance aspect of the Cougar had disappeared.
