The 2014 Mazda 2 has more space inside than its appearance would suggest, though its subcompact status means that four larger adults will still have to negotiate their accommodations to fit eight legs into the available space. Legroom is good for four people under 6 feet tall--which is when they'll start to run out of headroom too. If the two front passengers are tall adults, the rear seat is really restricted to children or teenagers.
Overall, we think the Mazda 2 is at its best as a two-seater, with the rear seat offering substantial cargo volume once it's folded flat. The lines are simple, almost monastic, and the look is pleasant but unremarkable. Mazda tends toward darker shades for its interior materials, but they're not overly grim or at all cheap-looking--and the large expanse of windows means the cabin stays lighter than many other subcompacts with stylishly upswept window lines that make them much more cave-like inside.
The front seats are supportive and comfortable, though broader adults may find them slightly narrow. The contrasting red piping of the Touring model adds a pleasant splash of style to upgraded seat fabric, though the basic upholstery is a step up from plain old cloth. As long as you're not expecting huge amounts of luxe, panache, or features, the Mazda 2's cabin is straightforward and serviceable. The one drawback is noise; the noise suppression from the hard-working little engine could use some work, especially for drivers who rev energetically to keep the car hustling along. Our test cars have been admirably free of squeaks, rattles, or groans, indicating good build quality.
