The center dash panel is formed by an arc that sweeps upward across the dash to the right side of the car and an inverted parabola. The radio fits into the top of this area and includes a single-disc CD player. Part of the controls can be taken with you to discourage theft. Snuggled in to the left is the cigarette lighter/ash tray. Circular ventilation controls, less frequently accessed, fit below the radio and are styled in the New Edge theme, with buttons styled to fit the room available. The trunk release, on the left end of the dash, is triangular as well, shaped to fit into the intersection of the arcs outlining the instrument panel.

The overall asymmetry lends an informal air to the interior, but the feel of the interior is rich. The control knobs all have distinctive shapes for easy identification; rotary controls are rubberized for pleasing soft-touch operation. The steering wheel on the ZX3 is leather-covered and satisfying to touch. Even the plastics used on the dash and door panels have a finger-friendly soft-touch feel. Painted silver accents around the center dash give the ZX3 a modern look, while wood grain in the same area enhances the ZTS model.

The seats are comfortable with an exceptionally high hip point, 20 inches above the ground. The advantages of this seating include a better view down the road, plus more effective leg room front and rear, and it takes advantage of the Focus' roofline with headroom for the long and tall. It also makes entry and exit easier. The manual height adjustment on the ZX3 allows almost everyone to find a comfortable position behind the wheel and an easy arm's length away from the manual shifter.

The back seat of the ZX3 is best accessed by the young and agile, but both front seats do slide forward. Once back there, however, rear seat riders have lots of legroom, thanks to widely spaced runners under the front seats, plus adult-sized head and shoulder room. Versatility of the hatchback design is lost on most Americans, who prefer the more formal sedan profile with its conventional trunk, but this design is hugely popular among Europeans for its practicality. Fold the back seat of the ZX3 and there's 18.5 cubic feet of cargo space and a big door for access.
