The facelifted E53 featured new headlights, a redesigned grille, and updated bumpers, giving it a refreshed and modern appearance. The interior saw minimal changes but included an updated infotainment system with a color display. Notably, the facelift introduced a new 4.8-liter V8 engine, replacing the previous 4.6-liter unit, and the diesel engine received a power boost from 184hp to 218hp. The drivetrain was improved with the introduction of a 6-speed automatic transmission, and the xDrive all-wheel-drive system was upgraded. The hill descent control, the split-tailgate, and the torque distribution method were retained, contributing to the X5's success.
