5th Gen will be the 2017's,,, Nothing significant coming with ~2016's~.
While we are all 'wishing out loud', I'd like to see a Penta-based 4.8L V-8 with DI,,, Should be good for more HP and TQ than the current 5.7's with better MPG to boot.
But, as long as folks continue to automatically open their billfolds at the mere mention of the word 'Hemi', I don't know what they would call it,,,,
The current technology in the 5.7 is pretty dated,,, They've taken it about as far as it can go (with perhaps the exception of adding DI)
