Substantially reduced road and wind noise
Many improvements were made to structural rigidity and powertrain NVH performance to provide a quieter, more pleasant ride, including the reduction of high frequency booming noise sometimes heard when decelerating while further evolving a sporty engine note. Increasing the rigidity of components and joints also helped to deliver a quieter ride that rates among the class leaders. The sound pressure level of road noise was curtailed by 6 to 11 percent over the previous model, and wind noise was reduced by approximately 6 percent, to 59.0 dB at 100 km/h with a 5 m/s crosswind, placing the all-new Mazda 3 among the quietest in the class.
