In a recent development that has sparked intense debate, Cui Dongshu, the secretary general of the China Passenger Car Association (CPCA), has called for a strategic shift in China's automotive tax policies. Cui's proposal, which aims to curb the growing trend of larger and more powerful new energy vehicles (NEVs), has ignited a conversation about the future of sustainable transportation and the role of policy in shaping it.
The Problem of EV "Upsizing"
Cui highlights a concerning trend in the Chinese automotive industry: the increasing size and power of NEVs. He describes this trend as "extremely bad" and a significant waste of resources. The issue, as Cui sees it, is that the current tax system does not differentiate between NEVs based on their weight or power, allowing for an unchecked growth in vehicle size.
Historically, combustion-engine vehicles faced constraints due to displacement-based taxes, which discouraged the development of large SUVs. However, NEVs, which are not subject to these same constraints, have seen a surge in size and power, leading to what Cui calls "vehicle bloating."
The Impact on Roads and Resources
One of the key concerns raised by Cui is the impact of heavier NEVs on road infrastructure. Because NEVs are fitted with power batteries, they generally weigh more than their combustion-engine counterparts, leading to increased wear and tear on roads. This issue is exacerbated by the trend of longer driving ranges, which require larger and heavier battery packs.
As Cui points out, the average curb weight of new passenger cars in China has increased significantly, from 1,304 kilograms in 2012 to 1,704 kilograms in 2024. This increase in weight has a direct impact on the lifespan and maintenance costs of roads, a concern that is often overlooked in the race to develop longer-range EVs.
A Call for Reform
Cui's solution is twofold: he suggests establishing a standard system for economy vehicles to encourage purchases by ordinary people, and implementing tax and energy-consumption management measures to guide and constrain vehicle size. By doing so, he believes China can address the issue of "vehicle obesity" and promote more sustainable and efficient transportation.
This is not the first time Cui has advocated for tax reform. Earlier this year, he proposed a statutory road-usage tax based on mileage and vehicle weight, aiming to address the decline in fuel tax revenue and encourage more efficient vehicle use.
The Challenge of Lightweighting
One of the key challenges in addressing this issue is the cost of lightweighting vehicles. As William Li, founder and CEO of Nio Inc., noted, reducing the weight of NEVs is a complex and costly endeavor. In the final stages of vehicle development, shaving off each kilogram of weight can cost up to 1,000 yuan ($147). This highlights the significant engineering and financial challenges associated with producing lighter, more efficient vehicles.
A Broader Perspective
Cui's proposal raises important questions about the role of policy in shaping sustainable transportation. While the trend of larger, more powerful NEVs may be driven by market competition and consumer demand, it is essential to consider the long-term environmental and infrastructure impacts. Policy interventions, such as those proposed by Cui, can play a crucial role in guiding the industry towards more sustainable practices.
In my opinion, this issue goes beyond China's borders. As the world transitions to electric mobility, it is crucial to consider the broader implications of vehicle size and weight on global resources and infrastructure. While larger EVs may offer certain advantages, such as longer ranges, we must also consider the trade-offs and ensure that our transportation systems are sustainable and efficient in the long term.
What makes this particularly fascinating is the delicate balance between consumer demands, industry innovation, and policy interventions. As we move forward, it will be interesting to see how these factors interplay to shape the future of electric mobility.
