What does DHT hybrid technology mean?

DHT hybrid technology is a highly integrated, high-efficiency, multi-mode oil-electric hybrid system that adopts dual-motor series-parallel hybrid technology, achieving a balance between high efficiency and high performance across all speed ranges and scenarios. The technology includes: This system comprises three powertrain configurations: 1.5L+DHT100, 1.5T+DHT130, and 1.5T+DHT130+P4, as well as HEV and PHEV solutions, covering models from compact to medium-large segments. In terms of parameters: The DHT system integrates two high thermal efficiency hybrid-specific engines (1.5L/1.5T) with maximum power outputs ranging from 102 hp to 156 hp. The integrated drive motor power ranges from 136 hp to 177 hp, while the P4 rear axle motor delivers a maximum power of 184 hp.
DHT hybrid technology stands for Dedicated Hybrid Transmission, which translates to a transmission system specifically designed for hybrid vehicles. Unlike Toyota's planetary gear hybrids, the characteristic of DHT is that it's a comprehensive solution designed exclusively for hybrid systems, integrating both the engine and electric motor within a single transmission housing. The most intuitive experience when driving such vehicles is the exceptional smoothness—quiet and fuel-efficient at low speeds using electric power, while at high speeds, the engine directly drives the wheels for higher efficiency, and it can even recharge while driving. Many domestic car manufacturers are now adopting this technology, such as Geely's Thor Hybrid and Great Wall's Lemon Hybrid, which fall into this category. The combined fuel consumption can be as low as around 4 liters, and the driving experience is completely free from the jerky sensation typical of traditional fuel-powered cars.
Simply put, the DHT is an intelligent and efficient hybrid system. A friend of mine who bought a DHT hybrid car keeps praising it every day. Its core concept integrates the engine, generator, and drive motor into a dedicated transmission mechanism, with a computer making real-time decisions on when to use electricity and when to use fuel. For example, it runs purely on electricity in traffic jams, making it quiet and cost-effective, while during acceleration, both the engine and motor work together to deliver a strong push-back feeling. At high-speed cruising, it switches to engine direct-drive mode, which is particularly fuel-efficient. This design reduces energy conversion losses compared to traditional hybrids and has a more compact structure. For instance, the Chery Kunpeng DHT even offers a three-gear transmission option, providing more power for climbing hills and overtaking, with fuel consumption of just a few liters per 100 kilometers, meaning fewer trips to the gas station.
The essence of DHT hybrid technology is equipping the car with an intelligent energy distribution brain. Having test-driven it several times myself, the most noticeable feature is the automatic switching between three modes: starting with electric power like driving an EV, engine charging + motor drive working in tandem during acceleration, and the engine taking over directly at high speeds. The specially designed transmission mechanism avoids the gear-shifting jerks found in traditional fuel cars, ensuring smooth and seamless power delivery. This technology has been most widely adopted by domestic car brands in the past three years. For instance, BYD's DM-i follows a similar approach—requiring no large battery while eliminating range anxiety, making it highly economical and practical for average families.
