1977 Oldsmobile Toronado XSR

The Oldsmobile Toronado was the third most powerful American car of 1977. Note that the T-Top roof depicted in this brochure image never reached production.

Perhaps the easiest way to demonstrate the extent to which emissions equipment and low-octane unleaded fuel had impacted the power output of new-vehicle engines is to note the following:

The most powerful engine available from AMC–the 360-cubic-inch V8–was good for just 140 horsepower.  Meanwhile, AMC’s 304-inch V8 had been emasculated to just 120 horsepower.

Still, not every maker had been hit as hard as AMC by the double whammy of clean-air- and low-lead regulations. Shoppers looking to crack the magic 200-horsepower line could still do so, though just barely.

Presented here are the five most powerful American vehicles of 1977. If you’ve spent time with any of these “muscle cars,” do tell us about it.
