A new energy vehicle purchased just last month may lose its cutting-edge appeal in as little as one month. Nowadays, car buyers are increasingly grappling with the pervasive anxiety of feeling like their vehicle becomes outdated almost immediately after purchase. In the era of fuel-powered vehicles, mainstream models typically underwent generational updates only every few years, a pattern that provided a sense of stability and longevity for consumers. However, this traditional model is now being disrupted, as the product cycle for new energy vehicles has been significantly shortened. New car models often rely heavily on launch marketing strategies and exclusive incentives for early adopters to drive short-term sales surges, resulting in a rapid uptick in delivery volumes. Yet, this initial boost is frequently short-lived. With the constant influx of competing products at similar price points, a proliferation of homogeneous models, and growing consumer hesitancy, sales quickly taper off. As a result, the sales trajectory of new energy vehicles tends to exhibit a series of sharp, pulse-like fluctuations rather than a steady, sustained growth.
