All cars with powerful engines qualify as muscular, according to our poll

What is a “muscle car”? 

We offered four definitions in our most recent weekly poll:

• Only the big-engine midsize cars from the late ‘60s and early ‘70s, such as Pontiac GTO and Chevelle SS.
• Don’t forget Chrysler’s muscular letter cars, Chevy 409s and others from the ‘50s and early ‘70s.
• Any of the powerful Detroit machines from the late ‘60s and early /70s, including Mustang Boss and Camaro Z28.
• Classic Detroit muscle but also modern high-performance cars.

While Detroit muscle from the late ‘60s and early ‘70s, including Mustang and Camaro, drew 21.05 percent of the votes, by far the most popular definition as “All of the above,” with 52.63 percent.

The strict GTO/SS definition drew 15.79 percent of votes, classic Detroit muscle plus modern high-performance and Chrysler 300s, Chevy 409, etc. each drew only 5.26 percent.

Our new poll asks how often you drive your collector car.
