The entry-level S is the powerful foundation of the Titan XD, but it offers little more than the basics, but it does avail itself in all three cab sizes. Driver-assist features are limited to a rearview camera, while infotainment comprises a seven-inch touchscreen display, four speakers, AM/FM/CD playback, Bluetooth hands-free calling and audio streaming, Apple CarPlay and Android Auto, and SiriusXM. All three body variants are available to the S trim, as are both engine options. Hill start assist and ABS brakes are standard.
