For
1972, only two of the model lines received major restyling, the Torino and
Thunderbird. All others either remained the same or received only very minor
trim changes. It was a significant year in the respect that all engines were
required to run on unleaded gasoline requiring a maximum compression ratio of
around 9.0:1. Also, engines were no longer rated at brake horsepower. Beginning
in 1972, all engines were rated in SAE Net horsepower, or the theoretical
horsepower after deducting for the drain caused by the accessories and
transmission. This fact notwithstanding, the 351 Cleveland V8 still generated
nearly 300 SAE Net horsepower, making it one of the most powerful engines being
produced that year. Pollution requirements and rising insurance rates, plus the
lower compression ratios, meant considerably restricted performance. As a
result, 1971 is almost universally considered to be the end of the muscle car
era.

The Pintos were unchanged from the 1971 models
with exception of a larger rear window on Runabout models and the addition of a
two door station wagon.
