Iseki announced the development of an unmanned tractor that operates without a pilot under the supervision of a human operator. With 123 horsepower, one of the largest in Japan, the tractor will support labor-saving agricultural work amid the trend toward large-scale farming. Priced from 21.9 million yen, the tractor will be marketed to large-scale farmers, mainly in Hokkaido.
The company’s human-supervised robotic tractor, which previously had a maximum power of 98 hp, has increased its power to 123 hp, thereby expanding the range of work and reducing the time required. It also reduces the time needed to train farmers who are unfamiliar with operating the tractor, allowing them to work more efficiently.
Suzuki says it will withdraw from four-wheel vehicle production in Thailand. Production at the local subsidiary will cease by the end of 2025, and vehicles made at the main plant in India will be exported to Thailand for sale. Thailand has long been a stronghold of Japanese automakers, but Chinese automakers have gone on the offensive with low-cost EVs, and with Subaru’s decision to pull out, the plight of Japanese automakers is becoming more apparent.
Suzuki Motor Thailand (SMT), a local subsidiary, will cease production by the end of 2025, and SMT will focus on sales and customer service in Thailand. Thai Suzuki Motor, which produces motorcycles and outboard engines, will continue operations.
Komatsu has announced the development of a hydrogen-powered generator that will be used to power an electric mini excavator. It can be transported to the job site, allowing electric construction equipment to be used in places where there is no electric power infrastructure. The system will be tested at customer sites by September 2024.
The generator was developed in cooperation with DENYO. The generator is 3.1 meters long, 1.1 meters wide and 1.7 meters high. It generates electricity by mixing up to 40% hydrogen with light oil. HVO fuel (hydrogenated vegetable oil), a type of biofuel made from waste cooking oil, can also be used.
Komatsu has developed hydrogen-blended combustion power generators for use in on-site power generation at factories and other facilities. The company sells seven types of electric construction equipment but is unable to supply power to sites where there are no power distribution networks, so it has been working to commercialize an electric power supply infrastructure.
Korea’s Hyundai Motor Group is going on the offensive with hybrid vehicles. Its subsidiary Kia plans to introduce HV models in nine of its main models, doubling its current sales volume to 800,000 units by 2028. Kia will temporarily review its investment focus on EVs, where competition is heating up globally, to flexibly respond to market trends.
In early April, Kia’s CEO showed signs of impatience at a business strategy meeting in Seoul, admitting that the EV market is slowing down and pushing back the goal of surpassing sales of 1 million EV units by 2026 to 2027.
At the same time, he announced the expansion of HVs: by 2028, he will introduce HVs in nine major models worldwide, increasing HV sales from 372,000 units (12% of the total) in 2024 to 800,000 units (19%).
Rankings of new vehicle sales in Southeast Asia are shifting, with Malaysia overtaking Thailand to take second place in 2023. The Philippines overtook Vietnam to take fourth place. EV sales continue to grow across the region, particularly in Thailand.
New vehicle sales in six major Southeast Asian countries, including Indonesia and Thailand, totaled 3.34 million units in 2023, down 2% from the previous year. This was the first decline in three years. Rising interest rates weighed on the market. In Southeast Asia, customers with low equity often buy cars with car loans, which was affected by higher lending rates and stricter underwriting.
Despite the headwinds, sales increased in Malaysia and the Philippines. Sales in Malaysia rose 11% to 790,000 units, a record high, and the country became the second largest market in the region for the first time. The introduction of sales tax exemptions for domestically produced vehicles as part of an economic stimulus package provided a boost.
On March 28, Kubota unveiled the first prototype of a fuel cell-powered tractor. Although no release date has been set, the company will consider installing fuel cells in unmanned, automated tractors. Kubota is also developing battery-powered agricultural equipment, but the company believes that hydrogen-powered fuel cells will be effective for medium-large sized agricultural equipment.
Kubota is rushing to commercialize fuel cells because it believes demand will grow in developed countries such as Japan, Europe and the United States as a result of the trend toward decarbonization. The prototype machine has about 60 horsepower and has three hydrogen tanks installed above the cabin, which are used in Toyota’s Mirai fuel cell car. It generates electricity by reacting hydrogen with oxygen to power the engine. In the experiment, a tractor was equipped with a plowing unit to till the soil.
The South Korean government announced a plan for a semiconductor industrial park in which Samsung Electronics and SK Hynix will invest a total of 622 trillion won (approx. $470 Billion). With Japan and Taiwan aggressively investing in the semiconductor industry, the government aims to compete with them by establishing the world’s largest base and stabilizing the supply of semiconductors to Korea.
According to the plan announced by the government, Samsung Electronics and SK Hynix plan to invest 500 trillion won and 122 trillion won, respectively, by 2047. In addition to the existing 21 factories, 13 new semiconductor factories and 3 research facilities will be built. The semiconductor industrial park, which stretches from Pyeongtaek to Yongming, is expected to become the world’s largest manufacturing base with a monthly production capacity of 7.7 million wafers by 2030.
Kubota is considering in-house production of batteries for electric agricultural equipment. It is considering developing and designing its own batteries and building a new plant in Japan.
The company intends to launch electric tractors and mowers in Europe and the United States by 2030. Kubota is preparing for increased demand in Europe, the U.S., and other markets by establishing a system for in-house production of batteries, which determine the running time of electric agricultural machinery.
Kubota currently manufactures diesel engines for agricultural machinery, mainly in Thailand and Japan and ships them to the United States and Europe for final assembly. Regarding batteries, which are a key component of electric agricultural machinery, President Kitao said, “As with engines, we would like to be able to produce batteries for Asian markets in Thailand, and those for Japan, Europe, and the United States in Japan.”
Toyota Motor Corporation and Chiyoda Corporation have announced the joint development of a hydrogen production system. The two companies plan to begin demonstration tests at Toyota’s main plant in fiscal 2025 and hope to begin marketing the system around fiscal 2027.
The system will produce hydrogen by electrolyzing water. It will have an output of about 5 megawatts and will be able to produce about 100 kilograms of hydrogen per hour. The new plant has a footprint of 6 meters wide by 2.5 meters deep, about half the size of a typical plant. By linking multiple plants, the production volume can be significantly increased.
Hyundai Motor Company is developing a hybrid vehicle for its Genesis luxury brand. The company had planned to focus on EVs and FCVs for the Genesis, which will be launched after 2025. The recent slowdown in the growth of the EV market has forced the company to change its strategy.
According to industry insiders, Hyundai Motor is developing a hybrid engine and related systems for the Genesis, which is expected to be launched in 2025. Hybrid models will be added to the mainstream GV80 and GV70 models. The company plans to expand its HV lineup under the Hyundai Motor and Kia brands as well, having decided to introduce HVs under its luxury car brands due to the risk of slumping sales if it continues to shift more toward EVs. Hyundai Motor’s HV sales in 2023 were up 53% from the previous year to approximately 380,000 units.
