Build quality can be felt by customers at the moment they look at a vehicle. At Mazda, we combine the expertise of our design, engineering, testing and research, and production departments as we strive to achieve fine build quality in each and every part.

The purity of a car's design depends greatly on the gaps between different parts. Mazda aims to improve the quality of our final products by making these gaps as small as possible. For the vehicle's exterior, we work to maintain the smooth, uninterrupted lines of the original design by enhancing the accuracy with which parts fit together. We try to close the gaps between the headlight units and the front bumper, between the hood and the fenders, and the gaps surrounding the doors and liftgate. In the interior too, we are developing ways to reduce the number of visible parting lines, and have eliminated the scoring marks on the instrument panel that, on many cars, show where the passenger-side airbag is fitted. Mazda interiors are neat and attractive.

Audible sounds are also important factors that influence a vehicle's quality. Paying particular attention to the noise made by the doors opening and shutting, Mazda researches frequencies and damping effects to ensure all the mechanisms in its products produce sounds that are pleasant to hear.
To reduce unpleasant high-frequency noises, we apply a special low-friction coating to door latches and use damping on the door panels. Then we magnify the satisfying low-frequency clunk of a door closing by ensuring a uniform rigidity throughout the door panels. Also, by optimizing the positioning of the side beams and properties of the adhesive, we control the vibration characteristics to promote low-frequency noise.
