Its name says it all—the Dodge SRT Charger Hellcat’s  V-8 delivers 707 horsepower and 650 lb-ft of torque, accelerating to 60 mph in 3.6 seconds.  Buckle up the family—there are seats for all inside the world’s most powerful production sedan. Springs and shocks are softer than the 2-door brother car Hellcat Challenger and the wheelbase is longer, taming this Hellcat just enough to make it tolerable when the family is not in the mood for dad to show off.  But the menacing appearance will prompt challenges from other drivers having something to prove.  And dad knows that while the Hellcat rests in street mode it’s anxious to let out that Hellcat roar and pounce into sport or, God forbid, track mode with launch control.  Hydraulically assisted steering and Brembo brakes help reassure control of the explosive acceleration.  Behave Dad, or Mom will hide the red key!  (Hellcat comes with two keys:  A red fob gives access to the full 707 hp, a black one leashes back the kitty to 500hp.)
