I may be wrong here,....but I'm pretty sure the Hellcat can do what the Z06 can in the 0-60. (I do believe they are both in the 3.5 range.) Now that is VERY impressive considering how much the Hellcat weighs and how much the Z06 weighs, going head to head stock to stock. Both are killer cars and I wouldn't mind either one actually. I was actually thinking Z06 before the Hellcat.
And let's not forget here,...we're taking stock to stock cars here. Not modified to stock cars. If you're car is modified, then what happens when the Hellcat becomes modified? What's the limit on HP and TQ then? 900 HP and 800 lbs. of TQ? (Of course power/torque isn't everything, it's how you get it to the pavement.)
Great time for us modern day muscle car lovers.
