What does dual-engine car mean?

[McQuinn]

A dual-engine car is a highly efficient and low-consumption vehicle equipped with both an electric engine and a gasoline engine. Additionally, this type of car employs a special system to capture the energy generated during braking and stores it in the onboard battery. The electric engine consumes no energy when idle, remaining completely shut off, and it uses less energy than the gasoline engine during low-speed driving. The gasoline engine performs better at high speeds, delivering more power for the same engine weight, which means the electric engine is more effective in stop-and-go traffic during peak hours. The advantage of the gasoline engine is that it produces no exhaust emissions, reducing smog pollution levels, and it automatically starts to recharge the battery when the charge is low, eliminating the need for a power cord.

The dual hybrid car is essentially a gasoline-electric hybrid vehicle. I've been driving Toyota's hybrid version of the Camry for three years, and the most noticeable experience is that the engine hardly works in traffic jams, relying entirely on the electric motor for propulsion, with unbelievably low fuel consumption. Last month, I took a long-distance trip covering 900 kilometers on just one tank of fuel. The difference between it and ordinary hybrid cars lies in its more sophisticated intelligent control system, which allows the engine and electric motor to cooperate like a relay race—using electricity for quiet and fuel-efficient low-speed city driving, while the engine kicks in for ample power at high speeds. Many brands are now developing similar technologies, but Toyota's dual hybrid system has the best reputation, and its battery durability has stood the test of time.

My friends often ask me if hybrid cars need to be charged, but actually, there's no need to plug them in at all! Their electricity comes entirely from brake energy recovery and surplus engine power. I've studied how it works: when you brake, kinetic energy is converted into electricity and stored in the battery; at red lights, the engine automatically shuts off, and the battery powers the air conditioning; during acceleration, the electric motor kicks in first, and the engine only starts once speed picks up. This seamless transition technology reduces fuel consumption by over 30% compared to pure gasoline cars, making it especially suitable for urban commuting. Many people worry about maintenance costs, but nowadays, hybrid systems come with long warranty periods.

Simply put, a hybrid system means there are two engines hidden in the car—a gasoline engine and an electric motor. I test-drove the Levin Hybrid version, and at stoplights, it was so quiet it felt like the car wasn't even on. A light press on the accelerator, and it glided forward. The principle is quite clever: at low speeds, it uses electricity to avoid the most fuel-consuming phase of the engine, and during acceleration, both power systems work in parallel. The battery pack is placed under the rear seats without affecting the trunk space, and the overall weight distribution is even more balanced. Compared to pure electric vehicles, it eliminates range anxiety; compared to conventional fuel-powered cars, fuel consumption drops by 40%. In the used car market now, a three-year-old hybrid holds its value better than the same model with a gasoline engine.

Last week, I accompanied a colleague to test drive the Corolla Hybrid. The salesperson used a coffee machine analogy to explain the principle vividly: the gasoline engine is like a manual coffee grinder, time-consuming and material-wasting, while the electric motor is like instant coffee, efficient and convenient. The hybrid system automatically decides when to use 'instant coffee' and when to start the 'coffee machine.' The most impressive part of the actual driving experience was the energy recovery—going downhill, the battery charge increased noticeably. Although the car costs 20,000 yuan more, it can save over 30,000 yuan in fuel costs in five years. As for drawbacks, the engine noise during sudden acceleration can be a bit abrupt, but once you get used to it, it feels like the turbocharged kick.
