Ⅰ Innovative design of modern dual-motor hybrid system
Hyundai Motor's next-generation hybrid system uses "dual-motor drive". Specifically includes the P1 and P2 motors working together. The P1 motor is mainly responsible for the energy recovery of the battery, battery charging, engine start-stop and auxiliary power at low speeds, while the P2 motor is responsible for the main driving tasks of the vehicle, responsible for the main acceleration and regenerative braking of the vehicle. This dual-motor system with a clear division of labor makes the motor and engine more closely coordinated, reducing the frustration of power switching in traditional hybrid systems and improving the driving experience.
Hyundai's all-new Palisade, for example, is equipped with a 2.5-litre turbocharged hybrid system with a maximum power of 334 PS and a peak torque of 460 Nm, which is 19 percent more power and 9 percent more torque than a conventional 2.5-liter internal combustion engine. At the same time, the system has a fuel efficiency of up to 14.1 km/l, which is 45% better than conventional combustion engine vehicles. Hyundai also introduced a 1.6-liter turbocharged hybrid system, designed for mid-size SUVs, which not only improves fuel efficiency by 4%, but also increases torque from 367 Nm to 380 Nm, and accelerates even better. These data show that modern dual-motor hybrid systems can significantly reduce fuel consumption and improve the fuel economy of the vehicle while improving performance.
Ⅱ The key technology to improve fuel efficiency - overexpansion cycle
The significant breakthrough in fuel efficiency of modern hybrid systems is inseparable from the application of "over-expansion cycle" technology. By delaying the intake valve closing, reducing the compression ratio, and achieving a higher expansion ratio during the combustion phase, this technology enables the engine to make more efficient use of the fuel's energy, resulting in improved fuel efficiency and reduced emissions. Compared with traditional internal combustion engines, the over-expansion cycle technology can significantly reduce energy loss and improve combustion efficiency under the premise of ensuring power output.
This technology not only helps to improve the fuel economy of the engine, but also helps to reduce tailpipe emissions and meet increasingly stringent environmental requirements around the world. By applying this technology to its hybrid powertrain, Hyundai Motor offers an efficient and environmentally friendly solution for the automotive industry. When it comes to meeting the challenges of global environmental regulations, over-expansion cycle technology is undoubtedly one of the core innovations of modern vehicles in terms of fuel efficiency and emission control.

Ⅲ. Industrial significance: to meet the dual challenges of market and environmental protection
The launch of the modern dual-motor hybrid system is of great strategic significance at the industrial level. As countries around the world tighten environmental regulations, emission standards in major automotive markets are becoming more stringent. For example, the European Union plans to reduce CO2 emissions from vehicles by 55% by 2030 compared to 2021, a goal that poses a huge challenge for automakers. With the introduction of a dual-motor system, Hyundai Motor not only provides higher performance while meeting environmental regulations, but also provides consumers with an environmentally friendly and efficient vehicle option.
Modern dual-motor hybrid systems can be adapted to different sizes and types of vehicles, from small cars to large SUVs, with power ranges from 100 PS to 300 PS. This enables Hyundai to meet the diverse needs of different consumers, especially in urban commuting and long-distance driving scenarios, and the vehicle can provide both low fuel consumption and high performance, which greatly improves the market competitiveness of the product.
In addition, consumers are demanding more comfort, power and fuel economy from their vehicles. Modern hybrid systems offer low fuel consumption while maintaining the vehicle's dynamic performance, both in terms of acceleration and stability. This feature gives modern hybrid technology a strong advantage in the fierce market competition.
Ⅳ. Future outlook: the deep integration of hybrid technology and intelligent technology
Looking ahead, Hyundai Motor will continue to build on hybrid technology and further integrate innovative elements of intelligence and efficiency. For example, Hyundai plans to introduce the e-AWD system, which enhances traction by equipping the rear axle with a P4 drive motor and intelligently distributes power to the front and rear axles according to different driving scenarios to improve vehicle passability and stability. In addition, the e-VMC 2.0 technology will further optimize the vehicle's driving stability and comfort, including features such as e-Handling 2.0 (roll over), e-EHA 2.0 (front collision avoidance assist) and e-Ride 2.0 (vertical sway reduction) to enhance driver safety and driving experience.
With the rapid development of intelligent and connected technologies, modern hybrid systems will achieve deeper integration in the fields of autonomous driving and Internet of Vehicles. For example, vehicles can obtain traffic information in real time through Internet of Vehicles technology and intelligently adjust the power take-off mode to achieve the best energy saving effect. In autonomous driving scenarios, the hybrid system can automatically optimize the coordination between the motor and engine according to the driving status and safety requirements of the vehicle, further improving the energy efficiency and performance of the vehicle.
The deep integration of intelligent and hybrid technology will inject new vitality into the automotive industry and promote the development of the automotive industry in a more intelligent and environmentally friendly direction.
Ⅴ. Challenges and responses: the balance between cost and market perception
While modern dual-motor hybrid technology offers significant advantages in terms of performance and fuel efficiency, its adoption still presents certain challenges. First of all, the production cost of hybrid vehicles is high, especially the cost of core components such as batteries and electric motors, which may affect the speed of market adoption. While the cost of hybrid vehicles is expected to gradually decline as technology advances and economies of scale take place, automakers will still need to make adjustments in terms of cost control and product pricing in the short term.
In addition, consumer awareness and acceptance of hybrid technology is uneven. Some consumers may not have a good understanding of how hybrid systems work and what benefits they can use, which can influence their car purchase decisions. In order to increase consumer awareness, automakers need to help consumers understand the benefits of hybrid technology and increase market acceptance through multi-channel publicity and promotion, including technical seminars, test drive events, and media cooperation.
Battery technology for hybrid vehicles is also a key concern for consumers. Hyundai Motor has invested a lot of resources in the research and development of battery technology, and continuously optimizes the battery management system to ensure the safety and longevity of the battery. At the same time, automakers also need to establish a sound battery recycling and reuse system to reduce the environmental burden and further enhance the market competitiveness of their products.
