In the context of the continuous internal competition of domestic brands, consumers not only focus on the hardware parameters and mechanical qualities of the car when purchasing, but also pay more attention to the comprehensive performance experience, especially in terms of space, quietness, comfort, and driving experience. The third-generation all-new Roewe RX5, which went on sale some time ago, has made a lot of effort in terms of comfort.
For example, with regard to NVH that most people are concerned about, according to Roewe’s official publicity, the third-generation Roewe RX5 has improved high-perception areas such as engine vibration and sound quality, vehicle wind noise, vehicle road noise, and component noise from the source and path, and adopts multi-layer shock-absorbing and sound-absorbing design. In Roewe’s official tests, the noise of the Roewe RX5 at idle is lower than 36dB, and the vibration is 0.02m/s², comparable to pure electric models.
More than 41 sound-absorbing materials are applied throughout the vehicle, and acoustic partitions are used in 21 key locations such as the front cabin acoustic package, underbody acoustic package, and body cavity. For example, the sound insulation pad inside the front fascia uses a “sandwich structure” design with multi-layer shock-absorbing and sound-insulating design, which theoretically has a double wall effect that can reduce noise inside the engine compartment.
The all-new third-generation Roewe RX5 has adopted a flexible subframe structure to block vibrations from the ground, effectively suppressing road noise. The T-type engine suspension and the cone-shaped gearbox suspension structure can reduce vibrations. At the same time, the body torsional stiffness is as high as 25,000 Nm/deg, and the body modal frequency is as high as 45Hz, which can effectively reduce chassis deformation and suppress engine vibration noise. The high-mode front fascia at 190Hz reduces the overall vehicle response caused by engine vibration.
However, the above are all test results obtained by Roewe in the testing state. We all know that NVH is a complex engineering task, and the final results will still have to wait for the actual testing results in road environments. However, with so many special hardware optimizations on the Roewe RX5, it might really provide us with a surprise in NVH experience.
