Between its introduction in 1967 and the end of its production in 2002, the Mercury Cougar underwent some significant transformations. Originally, it was based on the Ford Mustang, and - except for the front grille - bore a close resemblance to its lower-end cousin. By the 1970's, however, Ford realized the need to compete with some top-selling competitors, so the Merc changed from a "pony car" into a mid-size luxury sedan, more closely resembling the Thunderbird of that time.

It was during the 1970's that a new piece of equipment - the Catalytic Converter - began to appear on all new vehicles. The reason was new Federal emissions standards; air quality was starting to become a serious issue.

In an attempt to curb amounts of deadly carbon dioxide and other toxic pollutants in the air, refineries began removing lead from their gasoline, which allowed the new device to be used. The first generation of catalytic converters were bulky, power-sucking devices that contained lead pellets. Today's Mercury Cougar Catalytic Converter is a streamlined, high-tech device that removes carbon monoxide and nitrous oxide - the two main ingredients of smog - from automotive exhaust. A platinum catalyst breaks the molecular bonds of these gases and converts them into CO2 and water vapor. Occasionally, a catalytic converter can wear out, or get clogged.
