A usable definition of hypocrisy is "the practice of claiming to have moral standards or beliefs to which one's own behavior does not conform".
In this case, a belief that car companies should not be subsidized by government while simultaneously accepting subsidies from government. The act (accepting subsidies) does not match the stated belief (shouldn't accept subsidies).
To take it a step further, he could be less hypocritical if he changed his stance to along the lines of "there shouldn't be EV subsidies unless the company needs them to stay in business", but to my knowledge that is not his position.
