Enrich an EV listing with electric range and charge time using the EPA fueleconomy.gov API instead of standard MPG fields

Steps
Resolve the vehicle to a numeric id via the menu chain GET /ws/rest/vehicle/menu/year, then .../make, then .../model, then .../options
Call GET /ws/rest/vehicle/{id} to retrieve the full vehicle record
For battery-electric and plug-in hybrid vehicles, read the EV-specific fields — electricity consumption (cityE/highwayE/combE in kWh/100mi), range/rangeCity/rangeHwy, and charge120/charge240 (charge time in hours) — instead of the city08/highway08/comb08 MPG fields used for gasoline vehicles
Check atvType to confirm whether the vehicle is a pure EV, plug-in hybrid, or conventional vehicle before deciding which field set to read
For plug-in hybrids, also check the phevBlended boolean, since blended PHEVs report separate phevCity/phevHwy/phevComb figures distinct from non-blended PHEVs
Known gotchas
Standard MPG fields (city08/highway08/comb08) are typically blank or not meaningful for pure EVs — code assuming every record populates those fields will misread EV listings
The API's default response format is XML rather than JSON for many endpoints in this family — confirm Accept-header/format handling before parsing or requests can return unparsed XML
phevBlended materially changes which fields are populated (phevCity/phevHwy/phevComb vs plain city/highway/comb) — treating all PHEVs the same will misattribute fuel economy figures
