That's interesting-- it seems that the Pacifica was given some special allowance/consideration. Car and Driver (May '20) specified that the credit was figured at $2500 plus $417 for each 5 kwh's of battery capacity. USNews (June '20):It’s actually around $450 per Kw. So any vehicle with a battery capacity over 16.5 kw will qualify for the Full $7500 as long as that manufacturer hasn’t used all its credits. That’s why the battery size in the Pacifica was 16.6kw. I got $7500 back when I bought that van.
"Except for models from General Motors and Tesla, all mainstream, mass-produced full-electric vehicles on sale in America qualify for the full $7,500 credit. General Motors and Tesla have exceeded the sales volume cap of the federal program, making their vehicles ineligible for the full credit (or any federal credit, in the case of Tesla).
A few plug-in hybrids qualify for the full federal EV tax credit. The list includes the 2020 Toyota Prius Prime, 2020 Honda Clarity PHEV, 2020 Chrysler Pacifica Hybrid, and upcoming 2021 Toyota RAV4 Prime. Other plug-in hybrids typically qualify for credits between about $3,500 and $6,300. "
Maybe the 4xe will get some special allowance, too??
