A range extender is merely a component and cannot drive on its own, but vehicles equipped with range extenders are capable of long-distance travel. This is because a range extender is an additional energy storage component installed in pure electric vehicles to extend their driving range. In other words, a range extender is a part that can supply extra electrical energy, enabling the vehicle to travel farther. Compared to traditional internal combustion engines, range extenders are equipped with smaller-displacement engines. During operation, they generate less power and noise than conventional engines while achieving higher efficiency. In the overall vehicle design, the range extender consists only of a generator and an engine, making its structure simple. As a result, it offers high energy transmission efficiency, along with favorable fuel consumption and emissions. Additionally, the motors in range-extended electric vehicles can recover energy during braking and downhill driving, reducing energy loss. Electric vehicles equipped with range extenders ensure that the battery does not operate in a chronically undercharged state. This helps prevent excessive battery discharge, which can shorten battery life, and further reduces the likelihood of traffic accidents.

Range-extended vehicles are absolutely capable for long-distance travel. I've driven several thousand-kilometer trips before and found them quite reliable. It's like an electric car with its own generator - first running on battery (typically 100-200 km), then when the battery runs low, the range extender kicks in to generate electricity using fuel, allowing continuous driving as long as there are gas stations. The combined range easily exceeds 800 km, so you don't need to worry about getting stranded on long trips. However, route planning is crucial - you need to calculate refueling points carefully since the range extender's average fuel consumption is around 6L/100km, slightly better than conventional gasoline cars. From my experience, the engine noise becomes slightly noticeable at high speeds, but the cabin comfort remains excellent, not affecting conversations or music listening. Remember to maintain range extender components regularly, like oil changes, to ensure long-distance reliability.

The range extender is essentially a small fuel-powered generator that only charges the battery and does not directly drive the wheels, making it quite efficient for long-distance travel. The engine operates at its optimal speed, with fuel consumption ranging from 5-7 liters per 100 kilometers, which is slightly more economical than a conventional gasoline vehicle. The range depends on the fuel tank size; common extended-range models can travel over 400 kilometers on a full tank, and combined with the battery range, the total mileage can easily exceed 700 kilometers. In terms of maintenance, attention should be paid to the generator's lifespan, with regular oil and filter changes, similar to a traditional engine. During long-distance driving, the power output is smooth, without any jerking, making it suitable for high-speed cruising. I've tried several cross-province trips with good fuel consumption control and stable performance, though efficiency slightly drops in cold weather, so it's advisable to carry extra water in the car to avoid overload.

Driving an extended-range electric vehicle (EREV) on long trips is quite enjoyable. It starts quietly and fuel-efficiently using electric power, and the range extender kicks in later to keep you going. As long as there are gas stations, the range is sufficient. However, emissions will increase during long journeys, though the carbon footprint is lower than that of a pure gasoline car since the electric driving segment produces zero emissions. In real-world usage, the fuel consumption is around 6 liters, and the combination of electric and gasoline power keeps costs relatively low. I recommend planning your route to avoid congested areas to minimize engine starts. Good ventilation in hot weather improves efficiency; the car handles mountain roads and corners stably, with no range anxiety—reliable and eco-friendly.
