Since 2008, this muscle car has been inspired by the first Challenger (1970-1974) without major changes year after year except for the appearance of ever more powerful engines. With its 797 horsepower (6.2 liter engine), the SRT Hellcat Redeye version is at the top of its category, but there are smaller and more affordable engines such as the 3600cc V6 and 5700cc V8.
