The 5.7 Hemi Challenger R/T is a very fast car right out of the gate. With 375 horsepower and 410 lb-ft on tap, the 5.7 Challenger can get from 0-60 in 4.8 seconds and do the quarter mile in 13.2 seconds. While that is nothing to scoff at, with some performance-oriented Challenger mods, a 5.7 Hemi Challenger can become a serious beast punching above its weight class.
