The ones I've seen only show miles. Some cars here do show a KM gauge inside the MPH gauge, but haven't seen that on the charger scat packs.There are so few '11-'14 R/Ts and SRTs on the roads in GTA....
Never seen the 6.4L , usually they were Super Bees with 392 Hemi
Could you please to post some pictures of your Charger from a side - to see how this badge looks like
Now I even more curious:
Folks in the US - on the speedometer, do you have dual grades in Miles and KMs or only miles?
