Mazda's Carbon Editions are always special, and this one is no different, though it mainly adds cosmetic bits. The exterior looks sublime in gray with the model-specific 18-inch alloy wheels. On the practical side, it gains heated side mirrors, while the addition of a power moonroof adds some natural light to the cabin. The best Carbon Edition feature is probably the red leather interior, though. It may be too flashy for some, but it does add a sporty element and some color to a cabin that could otherwise be a bit too dark.
