The iconic Ford Mustang, Dodge Challenger, and Chevrolet Camaro retain their place in the pantheon of muscle cars. The modern versions of these models deliver both eye-popping power and heart-thumping speed. However, they're not the only muscle cars on the road in 2020. The beefy nameplates in dealership showrooms today range from slick sports cars to classic coupes and all-out power demons. In addition to the standbys from Ford, Dodge, and Chevy, models from Kia, BMW, Lexus and others have joined the playing field with impressive power, agility and speed.
