For the 2024 Cadillac XT4, the engineers have undertaken a significant redesign. They have enhanced the infotainment system to create a more responsive and enjoyable 33-inch diagonal LED display with over a billion colors. This impressive screen now comes as a standard feature, eliminating the need for upgrades. Additionally, the new design focuses on spaciousness, with the XT4 boasting the most rear legroom in its class, measuring 39.5 inches.
