As of the 2015 model year, Dodge offers three V8-powered sporty models with rear-wheel drive that can be considered muscle cars: the Challenger, Charger and Viper. Of those three, the two-door Challenger coupe lineup fits the muscle car description in the purest sense.
The modern yet retro Challenger lineup receives a number of updates for 2015, including availability of a new high-performance Challenger SRT Hellcat model. Packing 707 horsepower thanks to a supercharged 6.2-liter HEMI V8 engine, the Hellcat blazes through the quarter-mile in 10.8 seconds and can reach 199 mph. Today's Challenger lineup features a design that calls to mind the classic muscle cars from the golden era of Detroit-dominated American motoring. Like 1960s and 1970s muscle cars, the Challenger can be fitted with one of several V8 engines ranging from powerful to a bit insane.
The four-door Charger sedan serves as a much sportier option than other large premium sedans such as the Toyota Avalon and Chevrolet Impala. Dodge also added the Hellcat package to the Charger lineup for 2015, with the same 707-horsepower supercharged V8. A recent update has given the performance sedan's design a little more muscle-car flair, such as a rear light bar running the entire length of the trunk lid as was included on classic Dodge designs.
Finally, the Viper has matured in its latest generation from a powerful muscle car into a refined, track-focused supercar. Still, its 8.4-liter, 645-horsepower V10 is the largest engine fitted on any modern car, giving it instant muscle-car credibility. The Viper can reach 206 mph, although it is actually slower than the Hellcat Charger and Challenger through the quarter-mile at around 11.5 seconds.
