What is the most powerful muscle car ever?
A great number of muscle cars have rolled off the factor floors since the early years of muscle cars back in the 1960s — The Mustang, Charger, Camaro and so many other muscle cars can lay claim to being “most powerful.” So, what makes a muscle car the most powerful muscle car ever? It has to be horsepower — after all, power is in its name. — But, does size matter? How about torque? Displacement? Does a supercharger help? I think we can agree that it all matters when making the most powerful muscle car. Everything about the car is important, but especially the engine. Quite simply, it needs to have power! Today, the most powerful muscle car ever is a fairly new car. It's an old name, but a lot more muscle.
With an unprecedented 707 horsepower HEMI Hellcat 6.2-liter engine and 650 lb.-ft. of torque, it's the most powerful muscle car ever. Dodge's most powerful V-8 is the Challenger SRT Hellcat.
The Challenger's new 6.2-liter Supercharged Hellcat engine is also the first factory supercharged HEMI. This is Dodge and SRT's first application of V-8 supercharger technology. For the first time in Chrysler Group history, the all-new 2015 Dodge Challenger SRT with a Hellcat engine comes standard with two key fobs -- red and black. The red key fob is the only key that can unlock the full 707 horsepower and torque potential of the Challenger SRT Hellcat engine; while the black key fob limits the driver to a reduced engine output of 500 horsepower.
This Challenger is without doubt the most powerful muscle car ever and has been redesigned and re-engineered with performance-enhancing technologies inside and out, including the new TorqueFlite eight-speed automatic transmission and an all-new interior inspired by the classic 1971 Challenger.
The 2015 Dodge Challenger and Challenger SRTs are built at the Brampton, Ontario, Assembly Plant.
