    Summary of accelerative forces on various cars.
    All done on a “roll”.
    Note to fairly/properly compare, one needs to compare to the gear that most closely matches the overall gear ratio, and/or redline speed of the car being compared to.
    Some observations:
    In winter conditions, even with sticky snow tires, there is insufficient traction to do anything in 1st and 2nd gear in the Hellcat – that will have to await excellent warm/sticky road conditions. (On the other hand, turbos and supercharged cars like cold inlet air temperatures, so the winter G-Forces are probably a bit higher than hot weather G-Forces).
    My original “Bad Boy” beast of a car was the 2003 Mercedes E55 AMG. Felt like an absolute brute back then. Had to launch it in second gear because it would not hook up in 1st. Had (going by memory) about 510 hp and 560 lb-ft of torque, but unfortunately also had a conventional 5 speed automatic. Look at its performance figures now compared to more recent cars!!
    The 2006 Z06 was, in retrospect, quite impressive on the other hand. (It had a really tall set of gears, so you need to compare it with one gear higher in most other cars - ie. 1st on the Z06, (and the ZR1), are equivalent to 2nd in all other cars - etc.
    The 2012 modified GT-R (and the F12 of course-740 hp and 500 lb-ft of torque) are still the standards against which all other cars need to be measured in terms of G-Force, BUT the Hellcat matches them – at least on a roll in 4th gear!
    The 2009 ZR1 (640hp, 600 lb-ft torque), also needs to be compared to one gear higher in the other cars, and is then mighty impressive, but the Hellcat matches it in 4th and 5th gears – the ZR1 is stronger in the 3rd gear equivalent.
    The 2015 GT3 does pretty well compared to the other high-revving, lower torque engines (but all its peak G runs had to be done above 7000 rpm). Had they given it better (lower) gear ratios, it might have matched some mighty impressive cars.
    The Hellcat pulls meaningfully stronger than the current generation E63 and M5.

    Should have mentioned, my Hellcat is a Charger with auto transmission.

    Anyone got some numbers? The new Telsa p85D has LUDICROUS mode with 1.1G pull! I wonder how Hellcats does against this. Costs freaking $15K for a new fuse and installation just to support that!

    I know some of you own Hellcats & a Gen5 Viper... Compared to the Viper, how is the acceleration of the Hellcat?
