The pursuit of high-quality cars by the younger generation of consumers is not only limited to appearance, configuration, power, etc., but also NVH performance is becoming an important indicator to measure the "sense of luxury" of a model. Not only that, but a quieter space can satisfy everyone's pursuit of high-quality entertainment experience.
Take Buick Envision PLUS as an example, the car adopts the latest generation of Buick QuietTuningTM mute technology, which is actively input NVH (noise, vibration and harshness) requirements during the development of the vehicle architecture, and lays a good foundation for vehicle silence with excellent vehicle mode at the beginning of the design. The optimized body structure, together with up to 75% of the vehicle's high-strength steel application, gives Envision PLUS extremely high torsional stiffness and excellent torsional and bending modes, resulting in excellent vibration and noise suppression, and the elimination of body resonances to the greatest extent. On this basis, Envision PLUS creates a quiet cockpit like a library through the triple barrier of noise reduction, noise isolation and noise absorption, together with ANC active noise cancellation technology.
In terms of noise reduction, the exterior styling of Envision Plus adopts a series of aerodynamic designs, resulting in a low drag coefficient and at the same time minimizing the wind noise during driving. Both the eighth-generation Ecotec engine and the luxury SUV chassis feature a number of silent technologies, such as the eighth-generation Ecotec 20t and 1The 5T direct-injection turbocharged engine adopts silent technologies such as balance shaft silent system, silent balance chain, transcendence alternator decoupling shock absorber, noise reduction and vibration reduction pulley, sunken variable displacement oil pump, and double-layer oil pan.
