Ford's Explorer-based Police Interceptor Utility is the SUV most American police forces actually drive today. Given GTA 6's Florida-style setting, fans expect a close copy for the in-game cops, and leak chatter points that way. Rockstar has not confirmed the vehicle or named it, so treat it as expected rather than real.
There is no confirmed in-game name or way to grab this police SUV yet. Cop cars are usually pulled from the world rather than bought, but nothing is official until Rockstar shows it. If it appears, expect roomy, stable pursuit handling like the real Explorer Interceptor.
