At the recently opened Guangzhou Auto Show, new energy vehicles once again stole the spotlight. Whether it was a foreign brand, a domestic automaker, or a joint venture, nearly all major automotive companies unveiled their latest electric and hybrid models at this year’s event. Industry insiders predict that China’s auto market is on the verge of a major push for energy-efficient technologies, particularly hybrid systems. The growing development of new energy vehicles has raised the bar for the steel industry, as these vehicles demand more advanced materials to meet performance and safety standards.
**The Rise of New Energy Vehicles**
In recent years, the automotive industry has faced increasingly strict environmental regulations. Traditional gasoline-powered cars are now seen as one of the main contributors to urban air pollution, making it essential to reduce vehicle emissions. As a result, many car manufacturers have turned to new energy solutions. In response, the Chinese government has introduced multiple policies to promote the adoption of electric and hybrid vehicles. For instance, the Ministry of Industry and Information Technology, together with the Ministry of Finance, the Ministry of Science and Technology, and the National Development and Reform Commission, issued a notice in September 2013, extending financial support for pure electric, plug-in hybrid, and fuel cell vehicles. According to the notice, megacities and urban clusters will be encouraged to deploy at least 10,000 new energy vehicles within the next two years.
Beyond national initiatives, many local governments have also relaxed restrictions on new energy vehicles, making them more attractive to consumers. This has further fueled the interest of automakers in showcasing their new energy offerings at the Guangzhou Auto Show.
Despite the strong support from both the government and the industry, China's new energy vehicle sector still faces significant challenges. By the end of 2012, only 39,000 new energy vehicles had been deployed nationwide. In the first half of 2013, production and sales reached just 16,381 units. The country's "Energy Conservation and New Energy Vehicle Industry Development Plan (2012–2020)" set ambitious targets: by 2015, cumulative sales of pure electric and plug-in hybrid vehicles should reach 500,000 units, and by 2020, the production capacity should hit 2 million, with total sales exceeding 5 million. Clearly, there is still a long way to go to meet these goals.
Industry analysts believe that while widespread adoption of new energy vehicles will take time, the 2013 Guangzhou Auto Show highlights the growing importance of this sector. The focus is shifting from mere display to large-scale production, with hybrid technology likely to lead the way in industrialization.
**New Energy Vehicles Demand Better Steel**
As automotive technology moves toward safety, energy efficiency, environmental protection, and intelligence, new energy vehicles bring higher demands on materials, especially steel. Kang Yonglin, a professor at the School of Materials Science and Technology at Beijing University of Science and Technology, emphasized that weight reduction is a key concern for new energy vehicles. To achieve this, high-strength and ultra-high-strength steel, along with aluminum composites, can be used. Optimizing design also plays a crucial role.
Thermoformed steel, in particular, is gaining popularity due to its low cost, simple composition, and high strength. It is widely used in anti-collision parts and side beams. Looking ahead, automotive steel will continue to evolve through the integration of modern metallurgy, materials science, and computer simulations, offering improved properties such as strength, stiffness, impact resistance, and formability.
He Wei, an expert from Tsinghua University’s Automotive Industry and Technology Strategy Institute, stressed that improving material properties is vital for lightweighting. Using high-strength steel in the right places and applying proper manufacturing processes can help achieve optimal structural performance.
This trend is already evident in new energy vehicles. For example, the SAIC Roewe 550 plug-in hybrid model features a body where 67% of the structure is made of high- and ultra-high-strength steel. Its ultra-high-strength UHSD body matches the strength levels of luxury cars.
Industry insiders believe that automotive steel will remain a critical material in the future, thanks to its advantages in safety, weight reduction, cost, lifecycle, and green manufacturing. Combining advanced forming technologies with lightweight materials like aluminum will help meet stricter performance standards.
In the future, automotive steel will leverage modern computing and design techniques to optimize components and overall structures, ensuring competitiveness and delivering comprehensive solutions to the industry.
