Despite being fairly old now, the Dodge Challenger soldiers on for 2021. This heavy and fuel-thirsty muscle car continues to offer a wide variety of models and powertrains, from a standard 3.6-litre V6 engine rated at 305 horsepower to an almighty supercharged 6.2-litre V8 that unleashes 807 horsepower in the new Challenger SRT Super Stock. The latter is specially designed for drag racing, just like the Demon was.
