This may help, but others will need to chime in & confirm.
I think Raven cars have a rated range of 370 miles; whereas the older ones had 335 miles. (Assuming you are getting a 100D). If so, ask the sales rep, to take pix of the dash that shows both the percentage & the miles. Extrapolating those numbers will point you if you are getting a Raven or not.
IMHO, the VIN does not necessarily show you if its Raven or not, especially if the build date was around the April to June timeline.
Good luck.
