2025 ST's are "Intelligent" 4WD, not AWD. Unsure of how a ST Line works There is a difference between AWD & 4WD. Also, the 4WD cannot be activated by any manual means. It does what it does automatically and it is not constantly in 4WD. I'm not a fan of it locking in, or out, of 4WD when it feels it is necessary. I would much rather have at least the option of being able to select if I want it to happen automatically or by my prompt. IMO, they are way overly making everything happen automatically in newer vehicles instead of driver prompted. Its just more electronic BS waiting to glitch out.
