During the Hellcat Charger reveal they mentioned the added weight helped to launch it off the line, however she is still one heavy beast. Only...and don't hold me to this...roughly 160lbs more than the Challenger. The added length of the body with the aerodynamics at play allow the Charger to have a higher top speed of 204mph (vs Chally 199). It is also slightly quicker in the quarter mile at 11s flat (vs Chally 11.2s), but it is a touch slower in the 0-60 aspect at 3.7s (vs Chally 3.5s).
Really, someone mentioned it before here but I forget who, the Challenger is a bit heavy for a coupe but it does have impressive power and the retro look is simply stunning! The Charger is slightly heavier but it plays against the European cars like BMW and the lot. Both vehicles are well priced for their markets as well, although in my opinion the Charger is more enticing to those shopping for 4 door super beast saloons vs people wanting a 2 door monster. The new Chevy stingray is also a pretty sweet ride for that category!
