    What gears are in my 2016 HC Challenger?

    So I just bought myself a 2016 Hellcat Challenger yesterday with the M6. I cannot find any reliable information ANYWHERE on what gears the 2016 M6's come with. I've heard 3.09, 2.62, 3.90 etc... Dodge's website was no help and the owners manual ONLY mentions a 3.90 but also doesn't mention the 6.2L HC motor.... Build sheet was also no help...

    Agree, 3.70 with M6 on Hellcat, all other M6 2015+ cars use a 3.90.

    Just for some added info. 1st gear in our TR6060s (M6 Hellcats) is 2.26, while 1st gear in manual-equipped 392 cars is 2.97. In fact all of the gear ratios are different including 6th gear which is .63 in Hellcats, and .50 in everything else with a manual.

    Abe. New Yorker livin' it up in Tulsa...
    2016 Redline Pearl Challenger SRT Hellcat. Stock for now, and packin' a 6-speed...
    1971 Lucerne Blue GTO. It "was" a 400/4-speed car, but now packs a "built" 455HO and M22 Rockcrusher 4-speed. Gotta love the Classics.

    My A8 Charger 392's 1st gear is literally pointless... It's such a short gear... But GOOD LORD the Hellcat M6 is so fun to drive! I broke tires loose at 65 today downshifting into 3rd to pass on the freeway... It's got a tone more power than I had originally thought... I'll be using the black key from now on!

    Ha!

    This chart from Allpar.com shows the difference in the standard and Hellcat M6 ratios, the Hellcat uses the road race ratio set that was also used with Viper. The higher ratio 2.26 first gear gives it more strength compared to the 2.97 used with 5.7 and 6.4 engines.
