Improved Cabin Quietness
For improved cabin quietness on both body styles, engineers adopted stiffer door modules for less vibration at the side of the car, reduced the level of wheel resonance and used additional soundinsulation materials. The Roadster Coupe adds comprehensive measures to suppress road noise and support its premium character. The front suspension cross member is filled with urethane to lower the transmission of road noise to the cabin, and reinforcements were added to the No. 2 cross member. Vibration induced noise is also suppressed by the addition of damping material to the frontmost section of the roof. Taken together, these measures insulate passengers of the Roadster Coupe better from low frequency road noise and bothersome high frequency sounds. As a result, the interior noise of the Mazda MX-5 Roadster Coupe facelift at 60 km/h on a coarse road is 2.7 dB quieter than the original model.
