The digital driver display and available head-up display keep critical information in view. Premium audio fills the cabin with rich sound, while multiple USB-C ports, wireless charging pads, and a spacious center console with enhanced storage keep devices powered and belongings organized.
Improved sound deadening creates a noticeably quieter ride for long highway stretches, and available dual-zone climate control with air filtration maintains comfort in dusty or extreme conditions.
