live in Virginia, elevation of about 2000 feet, my '18 SRT 6.4 hit 0-60 in 4.2-4.3 very consistently with launch and manually shifting, and a 1/4 mile in 12.8 sec. the new Hellcat now has over 650 miles on it, and is now unlocked, but i can not make myself be that hard on it yet, even launch in the SRT was violent. but maybe soon ill change the oil, and let you guys know what it will do.
