    I have had the good fortune to own and drive both a 2015 A8 Hellcat Challenger (Torred) and a 2016 hellcat charger (PCP). I swear that the charger is more responsive at lower RPM than the Challenger. Both cars are in default mode. Am I imagining things? The 2015 was received in November of 2014.

    Well that's pretty cool you have both... I have no idea if you're imagining things or not but if you want a second opinion feel free to swing by. I'm just 24 hrs away!:D:D:D

    Do a fuse pull on the challenger and compare again

    Excuse me for my ignorance, but what fuse are you talking about, what is it for and how does it improve responsiveness?

    To own one is constant love and smiles almost all the time. You must never have a bad day.

    Fuse 31, resets the PCM driving adaptives. Assume most of us drive like normal people 80% of the time, stuck in traffic, or don't always have safe opportunities to mash the throttle, your computer learns your driving habits. Your car will feel sluggish, throttle less responsive. You'll feel hesitation from the car. I believe it's after 100 starts, it stops learning.

    Now if you always drive it wicked then it probably won't do much, but doesn't hurt to try.

    Turn off car, pull out fuse # 31 for 30 seconds, reinsert and start up car. Hope this helps!

    Having a '15 Challenger with summer tires and a '16 Charger with all season tires, I can say that the Charger certainly feels a lot more wicked...have not compared actual times...the last time I floored the Charger it was from a 20mph roll and it lost traction for a few seconds on an upshift at 50mph...on dry pavement obviously.:)

    I've often wondered if one car actually has an advantage over the other. I believe that the Challenger is a little lighter but the Charger has a
    lower co-efficient of drag.

    Anyone actually lined up a couple of these cars? Or ran at the same track on the same day?

    No need to. Just lined them up and look at them. Story over. :)

    Pulled fuse 31 on challenger and as posted car was much more responsive. Thanks for the tip. Brought both cars to be tested/run by viper tech. Both cars were run at wot on street in default mode. Dealership has large open area and warehouse. Charger consistently logged slightly better0 to 60 and 1/4 mile times. By slightly I mean 0.3 in 1/4. Perction is also that the charger has slightly better throttle response. The challenger was delivered in Nov of 2014 (number 555). It received TCM and PCM flash in August of 2015. Interested in everybody's thoughts.

    Not discounting your expertise Desj06, but can anyone else confirm if this is true/correct? Seems like I did hear a former Challenger (not Hellcat) owner mention he didn't like his Challenger for this very reason of the car becoming sluggish because it learned the way he drove it 90% of the time day to day. He didn't know about a fuse though...pretty sure.

    Graycat, yes my son has a charger A8, and I have a challenger M6. We raced same day at blytheville arkansas airport In a mike my son ran 181.7.... I ran 181.4.... there wasn't alot of traction that day..

    Seems like pretty even cars to me
