The seats are great, with adequate bolstering. The 3s has adjustable lumbar support, and the hip position is elevated, reducing front legroom a touch, but providing excellent forward visibility as well as a tidy relationship with the pedals and especially the short shift lever. There's no dead pedal. The outside of the driver's right shin rests comfortably on the edge of the center stack.
The three-spoke steering wheel, leather-wrapped in the 3s, feels great in the hands, and the control buttons for the cruise control and sound system have a positive feel The dashboard shelf is golf-ball grainy, not unlike the new Cadillacs, although Mazda says it was the Porsche Boxster that inspired them. Instrument panel trim is Piano Black on 3i and Silver on 3s.
Three big gauges are dead ahead for the driver, but they're down in tunnels where they effectively hide from the glare of the sun. They are electroluminescent on 3s, which means day or night the numbers are lit in reddish-orange with blue highlights. Even without the color, the 140-mph speedometer would be awfully busy, with hash marks for miles and a smaller kilometer measure with more hash marks inside the mph numbers. The dash panel looks better at night than during the day, with the reddish-orange lighting having its chance to be seen. There are glowing rings around most of the dials including the cigarette lighter, in kind of a dull maroon.
The glovebox is huge (9 quarts), the door is dampened and the compartment has its own light. There's a deep but not long console under the driver's right elbow, and between the seats are two built-in cupholders with a neatly hinged cover in black plastic. The cupholders have a canal between them so other things such as a cellphone can be stored and easily reached there. The window switch for the driver is illuminated at night, a very useful feature.
The back seats in the five-door hatchback are surprisingly roomy and supportive, even when relatively tall people are sitting in front. There are acres of rear headroom and decent legroom with room for big feet to slide under the front seats. The rear door opening is a bit narrow, though.
Cargo space in the five-door with the seats folded flat in is 31.2 cubic feet. We came out of an Ikea store with an unassembled table in a flat box measuring 48 inches long and 30 inches wide, and it slid neatly into the back. Flipping the seats down is easy. We reached in from behind, pressed down on one small square button on each side, and an easy shove forward dropped each seat flat. A separate compartment is hidden under the floor. Fold the seats back up into their passenger-friendly position, and there's still 17.1 cubic feet of cargo room, a fair amount for a compact car. The rear floor section can be raised to create a partition, dividing the space into separate upper and lower compartments. The Mazda 3 can't carry as much cargo as a Toyota Matrix, but it's a lot more fun to drive.
Visibility is limited in the rearview mirror of the five-door by the two rear headrests and the center brake light, which intrude a little into window space.
The sedan has an average-size 11.4 cubic-foot trunk, but its rear seats still fold 60/40 for carrying long objects.
