AVAS, or Acoustic Vehicle Alert System, is the quiet‑car technology that alerts pedestrians to the presence of electric and hybrid vehicles, which can be almost silent at low speeds. The piece explains how regulators in the United States, Europe and China have mandated synthetic sounds for EVs, outlines the different types of alerts—from simple beeps to more sophisticated, brand‑specific tones—and discusses the balance manufacturers must strike between safety, driver experience and brand identity. It also highlights XPENG’s approach, showcasing how the Chinese automaker integrates customizable sound profiles and advanced speaker arrays to meet global standards while preserving a distinctive auditory signature. The article rounds out with a look at future developments, such as adaptive sounds that respond to speed and surrounding noise, and what these innovations mean for urban pedestrians and the broader push toward quieter, smarter mobility.
