The IONIQ 5, built on Hyundai’s E-GMP platform, boasts an 800V charging infrastructure and a 3.5-second acceleration from 0 to 100 km/h, all priced around USD 40,000. In comparison to other 800V competitors in the North American market, such as the Audi e-tron GT, Lucid Air, and Taycan, which are priced at approximately USD 80,000 to 100,000, the IONIQ 5 stands out with competitive features.

South Korea demonstrates a significant level of self-sufficiency in the strategic components of electric vehicles. Battery suppliers Samsung SDI and LG Energy Solution (LGES) rank among the world’s top ten battery suppliers.

Additionally, Hyundai Mobis stands as South Korea’s largest automotive parts supplier, offering a comprehensive product line that includes various components in electric motors and controls. With robust support from a powerful supply chain, this enhances Hyundai’s market competitiveness.

According to Hyundai North America’s reported sales figures for August 2023, the IONIQ 5 and IONIQ 6, both built on the E-GMP platform, collectively sold 5,235 units in the North American market. This reflects a remarkable 245% growth compared to the same period in 2022.

The year-to-date total sales of the IONIQ 5 and 6 reached 28,000 units by August, showing a notable 63% growth compared to the same period last year. It’s noteworthy that these achievements were made without the benefit of the USD 7,500 subsidy under the “Inflation Reduction Act.”

The success of the IONIQ series has bolstered Hyundai’s confidence in making this platform a core element, facilitating the development of related models and further investments in the electric vehicle business.

2. IONIQ Temporarily Pauses Entry into Chinese Market Amidst Intense Homogeneous Product Competition

With the rise of local Chinese automotive brands and the trend toward electrification, Hyundai’s sales in the Chinese market have plummeted from 1.14 million vehicles in 2016 to 250,000 vehicles in 2022, as per data released by the China Association of Automobile Manufacturers.

In 2021, Hyundai sold its first factory in Shunyi to Li Auto, and in June 2023, Hyundai announced plans to sell two more of its remaining four plants.

In the electric vehicle sector, the IONIQ 5 is built on an all-new electric vehicle platform, outperforming earlier models based on oil-to-electric conversion platforms in both overall efficiency and performance. With its affordable price, it presents a formidable challenge to equivalent models in Europe and the United States.

However, given China’s early development of new energy vehicle platforms and the completion of pure electric vehicle platforms by many domestic manufacturers, coupled with highly autonomous supply chains, IONIQ does not enjoy overwhelming advantages in China. Therefore, the initial focus on the European and American markets is a strategically sound decision.

As European and American automakers continue to establish pure electric vehicle platforms and competitors like Audi and Stellantis strengthen their technological exchanges with Chinese manufacturers, the advantages of the E-GMP platform will face challenges. To further enhance the economic scale of their products, the Chinese market remains a crucial challenge that Hyundai cannot ignore.

According to Yahoo’s report, recent developments in China’s automotive industry, particularly the electric vehicle sector, have been a mixed bag. While some companies have reported impressive export performance and surging delivery volumes, the overall market has faced challenges due to weak consumer demand and intense price wars.

Even NIO, which had previously pledged to enhance efficiency without layoffs, recently announced a workforce reduction of approximately 10%, affecting around 3,000 employees. This unexpected move has sent shockwaves through the industry and suggests that a layoff storm may be approaching the Chinese automotive sector.

Amidst numerous recent developments in the Chinese auto market, the most widely discussed topic is the announcement by NIO’s Chairman, William Li, regarding a workforce reduction of approximately 10%, with specific adjustments to be completed by November.

NIO, known as a market favorite and listed in both the U.S. and Hong Kong, has been considered one of the leading players in China’s new force of automotive companies. However, it now finds itself in the challenging position of staff downsizing, signaling a potentially tough year-end for China’s automotive industry.

While NIO, XPeng, and Li Auto, often hailed as representatives of the new forces in China’s automobile industry, had been at the forefront, NIO’s performance in 2023 seems to be lagging behind its peers.

In contrast to Li Auto, which has seen ten consecutive months of rising sales figures this year, and XPeng, which achieved a 292% year-on-year increase in October and set its record for single-month deliveries, NIO’s performance has been more volatile. Since reaching a peak delivery volume of 20,462 vehicles in July, NIO has struggled to maintain a consistent delivery rate of 20,000 vehicles per month.

Additionally, NIO’s losses have continued to grow quarter by quarter, with the company posting over ¥20 billion in net losses over the past year. In the same period, Li Auto recorded nearly ¥2 billion in profits, while XPeng faced losses of nearly ¥10 billion. Consequently, NIO holds the distinction of being the leader in losses among the new energy vehicle manufacturers. NIO’s layoffs serve as a cautionary signal, highlighting the pressing need to cut costs and enhance efficiency.

Amid China’s economic slowdown and intensified market competition, NIO’s challenges represent just a microcosm of the broader Chinese automotive industry. It’s not just NIO; in 2023, several automotive companies have already begun layoffs or faced closures. Examples include Levdeo, which filed for bankruptcy; WM Motor, which already closed its doors; and Enovate, which announced a suspension of operations.

Furthermore, the chill in the market is also affecting automotive supply chain companies. An industry insider candidly revealed that except for BYD and Li Auto, most car manufacturers are in the process of downsizing, indicating that the Chinese automotive industry is currently experiencing a major shake-up and a fierce battle for survival.
