Tested NIO at a Friend's Request; Now I Get Why Range Extenders Are Losing Steam

Is it worth trying? Yes. But the insights you gain might differ from what you expect.

A friend recently wanted to switch cars and kept talking about NIO. I didn't have a strong stance on range-extenders vs. pure EVs; after years in this industry, I'm used to looking at data before making judgments. The day he dragged me to the store, my mind was on something else: Qin Lihong said that by year-end, the penetration rate of pure EVs would exceed 50%, and NIO wouldn't do range-extenders. Two years ago, no one would have believed that, but after sitting in the store for half an hour that day, I felt there might actually be some truth to it.

First, let me explain penetration rate for those who don't know. It means out of every 100 new cars sold, how many are NEVs (New Energy Vehicles). Qin Lihong was specifically talking about pure EVs; if calculated separately, they need to exceed 50% in a certain month this year. That means more people will buy pure EVs than gas cars. Last year, this number seemed far off, but by July, the overall NEV penetration rate had already broken 60%, much faster than I expected.

The first thing we did upon entering the store was the salesperson asking if we could install a charging pile. This was the most unexpected point for me. In the past, when discussing pure EVs, the first question was always about range; now the first question is about home charging conditions. My friend said he didn't have a fixed parking spot, and the salesperson didn't panic, just took us to look at the battery swap station. There was a model of a swap station in the store; the explanation took about five minutes, not much more complex than refueling. I casually checked the public data in the backend, and NIO users' average daily mileage is only around sixty-something kilometers, similar to my clients who drive for ride-hailing apps. Simply put, the distance most people drive in a day is easily covered by any car.

The test drive wasn't worth mentioning; electric cars all drive similarly—quiet, fast, with a solid chassis. The cost calculation part was what changed my mind. The salesperson pulled up a table comparing range-extender cars at the same price point. The benefit of range-extenders is no range anxiety, but the problem is that you rarely use the engine for your daily commute; it only starts occasionally on highways. For that 10% scenario, the entire car has to carry an engine, fuel tank, and transmission system, adding up to nearly two hundred kilograms. Having done solutions for so many years, I hate stacking high specs for low-frequency needs, pushing all the costs onto the customer.

There were pitfalls too. My friend almost got misled by the salesperson into thinking battery swapping isn't as convenient as supercharging because there are fewer swap stations. Here, I helped him do the math: swapping takes three minutes, while even the fastest supercharging takes twenty minutes minimum. What can't you do while waiting at a highway service area? Moreover, swap stations are NIO's assets; they continue to expand them because the operational costs make sense, unlike third-party charging piles where no one manages maintenance.

Another easy pitfall is interpreting "not doing range-extenders" as NIO being stubborn. I watched Li Bin's forum speech, where he said the industry has entered the most brutal stage of the finals, and players will settle within the next three to five years. Translated, this means each company's technical route is basically set. Range-extenders are just transitional solutions. With battery costs, charging networks, and user habits for pure EVs all in place, why still carry an engine around? The bonus period for transitional solutions is over; it's time to wrap up.

Final advice. Whether you buy a NIO or not, go test drive a pure EV this weekend. Don't just look at parameters; calculate based on your own commute distance. Make a table comparing fueling vs. charging costs and maintenance differences. After my test drive that night, I did the math for myself and found that for my driving pattern of 20,000 km a year, the total cost of ownership for a pure EV vs. a range-extender differs by several thousand yuan. This number is more convincing than any launch event.

What to try next? Pull out the mileage records of your family's gas car and calculate using the same method. You might find you don't want to drive a gas car anymore.
