Is the Dodge Challenger powerful enough for highway driving?

Common versions include the 3.6L V6 (303 hp) in the Dodge Challenger SXT/GT, the 5.7L HEMI V8 (375 hp) in the R/T, and the legendary 6.2L Supercharged HEMI V8 (717+ hp) found in the Dodge Challenger SRT Hellcat series. For buyers considering the Dodge Challenger, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
