Stretched in all dimensions, the Premier provided more interior room than any of its contemporaries. The interior was an all-new design by AMC's in-house staff under the direction of Dick Teague. It also included features that were considered unique at the time. The instrument panel featured "a heavy dose of electronics", with all driver controls housed within a fingertip distance from the steering wheel. It used an unusual dash mounted gear selector with a thin metal lever at the end of which was a grip handle; instead if the gear selector shifting downward in the traditional fashion, the lever dropped into the dash pod in which it was mounted. The climate controls used an unusual up-down button that cycled through the different heating modes, indicated by an array of lights. All of these controls were housed in a control panel on the right side of the steering column. On the left side of the column another control contained the light and windshield wiper controls. The turn signal control was also electronic returning to its centered position immediately after a driver signaled a turn, and a gong indicated its cancellation after completing a turn. The optional cruise control was built into the leather-wrapped steering wheel. Other features included intermittent wipers, as well as automatic variable-speed that adjusted wiper speed to the amount of water that hit the windshield; with less moisture, the slower they would move, but increasing their action if a passing truck splashed the windshield with a large amount of water. Standard on all Premiers was an electronically tuned stereo sound system.
