The sedan has a streamlined silhouette with a matte-finish front grille, emphasizing elegance and aerodynamic efficiency. The hatchback has a more aggressive stance, appealing to daily commuters who prefer a sportier appearance.

The CX-30 also exudes elegance, with its sculpted fenders and flowing lines. This is complimented by black cladding on the wheel arches and lower body, which provides a rugged touch.

Premium available features such as heated and ventilated front seats, dual-zone automatic climate control, and a heated steering wheel make every driving experience comfortable and enjoyable.

The CX-30 offers the greatest passenger legroom and headroom due to its accommodating shape. The Mazda3 hatchback and CX-30 contain similar cargo space, offering approximately 20 cu.ft. behind the rear seats and 45 cu.ft. (CX-30) or 47 cu.ft. (Mazda3 hatchback) with the seats folded down.


Technology

Both vehicles have a standard 8.8-inch infotainment touchscreen in lower trims and a 10.25-inch display in higher trims. Wireless Apple CarPlay and Android Auto come standard in both, but only the CX-30 features built-in Amazon Alexa in higher trims.
