The cockpit design is based on the Tazuna concept; a concept that refines the human-centered philosophy present in Lexus’ vehicle crafting. The Tazuna, Japanese for rein, is an important means of communication between a horse and its rider. Lexus’ interior concept draws upon this articulate, symbiotic relationship, and reinterprets the partnership between human and machine with an intuitive layout that forges a deeper mutual understanding through a seamless merging of Omotenashi-influenced design and cutting-edge technologies. The steering wheel switches, for example, are highly integrated with the head-up display to create a space where the driver can concentrate on driving. Navigation, audio, and various functions can be controlled without the need for extra eye movement or complicated switch operations.
