The X84 chassis was a radical departure from its predecessor, the Megane I. Renault pursued an ambitious design language characterized by angular lines and a "shooting brake" profile. However, the true innovation was found inside the cabin. The X84 was one of the first cars in its segment to move away from a traditional, symmetrical dashboard. Instead, it utilized a driver-centric cockpit. In top-tier trims, this cockpit was dominated by the NT8222A system. Unlike modern infotainment systems that rely on touchscreens, the NT8222A was a sophisticated display unit positioned centrally, controlled via a joystick-style remote situated behind the gear stick. This "fly-by-wire" approach to infotainment control allowed the driver to navigate menus without taking their eyes off the road, a safety philosophy that predated modern rotary controllers found in premium brands like BMW and Audi.
