  "account": "China is now the world's largest market for electric vehicles (EVs), with sales growth particularly strong in medium and large SUVs. As of 2026, the average EV sold in China weighed almost two tonnes, a 27.5% increase from 2020. Some large SUVs even weigh over three tonnes, making them as heavy as a light truck. This weight increase is attributed to factors such as larger batteries, hybrid powertrains, and consumers' desire for increased range, features, safety, and comfort. The trend is known as the \"autobesity\" phenomenon, wherein vehicles become increasingly heavy and laden with additional features. The battery energy density has risen, but range demands have grown even faster, necessitating larger batteries. A 100 kWh battery can weigh over 600 kg, accounting for a significant portion of a vehicle's weight. The demand for advanced features like lidar, radar, cameras, and positioning systems also contributes to the weight. Self-driving capabilities require more cooling, power, and complex components, further adding to the weight. This \"mass spiral\" effect leads to heavier cars needing more materials, which in turn increases manufacturing emissions. Battery production emissions are a major factor, with manufacturing processes accounting for 70% or more of a car's lifetime emissions. Additionally, heavier cars use more energy while being driven, resulting in higher lifetime energy consumption and carbon emissions. Heavier vehicles also contribute to increased air pollution due to higher tyre and brake wear, producing more particulate matter. This, combined with the increased risk of collisions and road damage, highlights the negative consequences of this growing \"autobesity\" trend in China's EV market.",
