New energy vehicles are getting "bigger and heavier", lightweighting is an industry development imperative.

Walking on the streets of the city, a noticeable change can be seen everywhere: new energy vehicles on the road are "getting longer and fatter." Whether it's a sedan or an SUV, the body width and wheelbase of vehicles are generally increasing, and the overall weight of the vehicles is steadily rising. Many new energy vehicle models are no longer light and agile, becoming "big guys" on the road. This silent trend of new energy vehicles "gaining weight" is reshaping the original ecology of urban transportation and highlighting the controversy surrounding the heavy weight of cars. Interviewees point out that car companies rely on increasing battery capacity, adding smart features, and strengthening the body structure in exchange for longer range and higher product premiums, but this also leads to issues such as mechanical performance degradation and increased maintenance costs for vehicle owners. There is a limit to the extensive weight increase, and lightweighting has become the inevitable answer for the new energy vehicle industry.
