The MX-30 features centre pillar-less freestyle doors with custom-designed hinges. The front doors open forwards to an angle of up to 82-degrees and rear doors backwards, to 80-degrees. The freestyle doors and framed glasshouse hint at the open, airy and spacious feeling of the cabin within.

SE-L Lux grade MX-30s feature 18-inch Silver Metallic alloy wheels and come with a choice of  five single colour body paint choices. They also feature a black B-Pillar garnish, black mirrors and LED taillights. All Mazda MX-30s feature a black front grille with bold signature Mazda badge.

Sport Lux and GT Sport Tech models feature 18-inch Bright Metallic alloy wheels and come with a choice of five single colour body paint choices, plus to give the MX-30 a unique two-tone look, there’s the option to go for Ceramic Metallic and Soul Red Crystal Metallic with a Brilliant Black roof and dark grey metallic side panels. There’s also the option to have Polymetal Grey Metallic with brilliant black roof and silver metallic side panels.

The range-topping GT Sport Tech’s distinguishing exterior features include rear privacy glass, Piano Black rear window trim. Across all MX-30 models the design aims to emphasise its beauty as a solid mass in what Mazda Design describes as a ‘human modern’ concept. 

Despite adopting freestyle doors with no centre pillar, the MX-30's bodyshell combines high strength with efficient energy absorption for excellent collision safety performance. Mazda’s engineers have incorporated the latest technologies and development concepts, including a carefully designed structure to protect the high-voltage battery.

The MX-30’s 366-litre boot is designed to provide adequate space for all manner of family lifestyles. A sub-trunk beneath the floor offers additional space for storing small items. GT Sport Tech cars fitted with Bose audio have a 341-litre boot due to restricted space in the sub-trunk underfloor storage. The seats folded volume is 1,171 and 1,146 litres respectively. The height of the tailgate lip is designed to make loading and unloading luggage items easier.

The MX-30’s suspension system features a MacPherson strut front and torsion beam rear set-up. By implementing the same measures as on the Mazda3 and CX-30 - such as the use of optimised bushings and a centre beam - the smooth and instantaneous transmission of force from the road surface to the driver has been achieved.
