Is it permissible to replace old taxi cars with new ones through the bank, given the favorable prices and installment plans, and the possibility that this measure may become mandatory in the future?

Dealing with usurious banks is impermissible except in cases of necessity or dire need, provided that the transaction is Islamically permissible. The taxi replacement project in Egypt, which involves a usurious loan from usurious banks, is not permissible Islamically due to its inclusion of the forbidden usurious loan, and it is not considered a necessity that permits engaging in it.
