Hybrid vehicles are suitable for long-distance highway driving. Since highways only require vehicles to be motorized and maintain a certain speed for highway travel, though the fuel efficiency advantage is not as pronounced. Below is relevant information about hybrid vehicles: 1. Concept: Refers to vehicles equipped with more than one power source: storage batteries, fuel cells, solar cells, or generator sets of diesel locomotives. Currently, hybrid vehicles generally refer to those with diesel locomotive generators plus storage batteries. 2. Advantages: With hybrid power, the maximum power of the diesel engine can be determined based on the average required power, operating under optimal conditions of low fuel consumption and minimal pollution. When greater power is needed and the diesel engine's power is insufficient, the battery can supplement it. When the load is light, excess power can generate electricity to charge the battery. Since the diesel engine can operate continuously and the battery can be constantly charged, its range is the same as that of conventional vehicles.

Hybrid cars are perfectly fine for long-distance highway driving, and in fact, they are even more worry-free than in urban areas. I've driven my hybrid on several cross-province highways, and when the engine directly drives the wheels, it's actually more fuel-efficient than the frequent stop-and-go conditions in the city. Especially for hybrids like Toyota's THS, the power battery is basically in a charge-discharge balance state on the highway, so there's absolutely no range anxiety. On one occasion, I drove continuously for four hours with the air conditioning on the whole time, and the fuel consumption was only 5.2 liters per 100 kilometers. The only thing to pay attention to is maintaining the tire pressure at the standard value, since hybrid cars are about 200-300 kilograms heavier than fuel-powered cars.

As a mechanic with ten years of experience, I often get asked by car owners whether driving hybrids on highways harms the vehicle. Modern hybrid systems are designed with highway conditions in mind, and when operating in engine direct-drive mode, the wear is no different from that of a conventional gasoline car. However, I do recommend not turning off the engine when taking a break at a service area every two hours, allowing the cooling system to continue dissipating heat from the battery. Last time, a Camry hybrid owner complained about lack of power when overtaking on the highway. Upon inspection, it turned out that long-term use of the eco mode resulted in insufficient motor assistance. Switching to sport mode solved the issue.

Just completed an 800km highway trip last week in my PHEV. The fuel consumption in charge-sustaining mode was indeed over 1L/100km higher than when fully charged, but refueling at gas stations along the way was completely stress-free. The intelligent driving system proved its worth - full-speed adaptive cruise control with automatic following made driving much easier, while automatic switching to pure electric mode in traffic jams provided a quieter experience. I recommend setting the SOC to maximum before departure to let the engine charge the battery more. Real-world tests show that when battery level stays above 30%, the motor torque for overtaking is instantly available - much more responsive than my family's 2.0T gasoline car.
