What is the difference between Dual Engine and hybrid?

[VonEmersyn]

The differences between Dual Engine and hybrid are as follows: 1. Different scopes: Hybrid has a broader scope. Broadly speaking, Dual Engine belongs to hybrid. Narrowly speaking, there are two types of hybrid power in the world: one is called Dual Engine, and the other is called other hybrid power. Hybrid generally refers to oil-electric hybrid, where a car is equipped with both a conventional fuel engine and an electric motor, each operating under its optimal working conditions to achieve efficient energy utilization. Dual Engine refers to the installation of two power engines, a fuel engine and an electric motor. 2. Different power: Generally, the electric power system used in hybrid cars includes highly efficient and reinforced electric motors, generators, and batteries. The batteries used can be lead-acid batteries, nickel-manganese-hydrogen batteries, or lithium batteries. The hybrid technology of Dual Engine belongs to full hybrid technology. Unlike other mild hybrid technologies, it has two power sources, an engine and an electric motor, which significantly improves power performance while greatly reducing fuel consumption. It is a technology that combines tradition and the future, implementing energy-saving and emission reduction in practice, hence the name "Dual Engine".

I've driven for many years and studied various hybrid technologies. 'Dual Engine' is actually Toyota's own hybrid technology brand name, specifically referring to their hybrid power system. Hybrid, on the other hand, is a broader concept encompassing all vehicles that use both fuel and electric power sources, including plug-in hybrids, full hybrids, mild hybrids, and more. The Dual Engine falls under the full hybrid category, characterized by not requiring charging as the battery is charged by the engine and brake energy recovery, making it hassle-free to drive. Hybrid vehicles cover a wider range; for instance, plug-in hybrids require manual charging to enjoy pure electric driving. Toyota's Dual Engine system uses a planetary gear design to distribute power, ensuring smooth operation and fuel efficiency, while other brands may have different hybrid structures. For example, BYD's DM-i is a plug-in hybrid that can be charged for longer electric-only range. When choosing, it's important to consider whether charging convenience is a priority for you.

The difference between Dual Hybrid and hybrid lies in that one is a brand-specific term while the other is a general term. Dual Hybrid specifically refers to Toyota's hybrid technology, just like Apple's iPhone is a trademark. On the other hand, hybrid is a general term for all hybrid vehicles, such as Honda's i-MMD and BYD's DM-i, which are hybrids but not Dual Hybrid. Technically, Dual Hybrid employs an oil-electric hybrid system with a small battery that recharges through energy recovery, saving fuel without needing to be plugged in. Other hybrids include plug-in hybrid technologies with larger batteries that require external power sources for charging. In actual driving, Dual Hybrid vehicles are very quiet at low speeds using electricity, and the engine starts smoothly with low fuel consumption but short pure electric range. Plug-in hybrids offer over 50 kilometers of pure electric range, qualify for green license plates, and enjoy policy benefits, making them suitable for users with charging conditions. When purchasing a car, don't be misled by the names.

Hybrid is a broad category, including plug-in hybrid, range-extender hybrid, and conventional hybrid, among others. The term "Dual Hybrid" is merely Toyota's trademark for its conventional hybrid system. The core differences lie in the battery and energy replenishment methods: Dual Hybrid vehicles have smaller batteries that are automatically charged by the gasoline engine and brake energy recovery, whereas plug-in hybrids in the conventional hybrid category use larger batteries that must be charged via charging stations. Driving a Dual Hybrid vehicle is like using a smartphone in power-saving mode—you never have to worry about running out of power, but the functionality is limited. Plug-in hybrids, on the other hand, are like smartphones with a power bank, capable of driving much farther on pure electric power. From an environmental perspective, Dual Hybrid vehicles emit less in urban areas but are less eco-friendly than plug-in hybrids on highways, especially when users rely solely on electric power. Technologically, Toyota's Dual Hybrid E-CVT system is highly mature, but other hybrid systems have their own advantages. When purchasing a vehicle, the most important consideration is your home charging conditions.

The term "Dual Hybrid" is Toyota's exclusive name for its hybrid system, while "hybrid" is a general term that includes plug-in hybrid (PHEV), hybrid electric vehicle (HEV), etc. The Dual Hybrid falls under the HEV category, characterized by: a small battery capacity (approximately 1-2 kWh), no charging port, fuel consumption as low as 4L/100km but unable to drive long distances on pure electric power. Other hybrids, such as PHEVs, have larger batteries (8-20 kWh) and can run 50-100 km on pure electric power. In terms of price, the Dual Hybrid is about 20,000 yuan more expensive than the regular version, while plug-in hybrids are even more expensive but may qualify for exemption from purchase tax. In terms of usage costs, the Dual Hybrid saves on fuel expenses, while plug-in hybrids can have even lower fuel costs if frequently charged. Regarding resale value, Toyota's Dual Hybrid is relatively stable, while other hybrids vary greatly. Choosing the Dual Hybrid is suitable for those who do not want to change their refueling habits, while plug-in hybrids are suitable for those with parking spaces who can install charging stations.

Hybrid models are currently very popular, but 'Dual Engine' and 'hybrid' are not the same thing. 'Dual Engine' is the brand name for Toyota's hybrid system, exclusively used in Toyota vehicles like the Corolla Dual Engine. 'Hybrid,' on the other hand, covers hybrid technologies from all brands, such as Honda's Sport Hybrid and Geely's Thor Hybrid. Structurally, the Dual Engine uses Toyota's THS system with dual-motor collaboration for smooth power transitions, while other hybrids may feature parallel or series designs. As an owner, the best part of driving a Dual Engine is the quick and silent electric start at low speeds, making it especially fuel-efficient in traffic. Plug-in hybrids within the hybrid category require charging but can run purely on electricity, making them ideal for short commutes. In the long run, maintenance costs for both are similar, with reliable battery lifespans. The key to choosing a car still lies in your driving scenarios and charging convenience.
