The Mercury Cougar was conceived in the early 1960s as Mercury’s upscale alternative to the Ford Mustang, initially part of the T-7 project after the Mustang’s success. Lincoln-Mercury aimed to create a car that combined pony car excitement with personal luxury, positioned between the Mustang and the Thunderbird in terms of comfort and features.

The Cougar name was chosen over alternatives like Mercury Apollo after marketing studies found it more evocative for buyers
