The Nio ET7 is a Chinese-made luxury electric sedan with a 1,000-mile battery option and a subscription model for battery swapping

The Nio ET7 is a mid-size luxury sedan built by Nio, a Chinese automaker founded in 2014. It seats five passengers, offers up to 1,000 miles of range through a battery-swapping system, and starts around 528,000 Chinese yuan (roughly $73,000 USD at current exchange rates). The car is currently sold in China, Singapore, and a few other Asian markets — not in the United States or Europe yet, though Nio has announced plans to enter European markets.

What sets the ET7 apart from most electric cars is its battery-swapping infrastructure. Instead of charging for 20 minutes to an hour, Nio owners can drive into a swap station, have a fully charged battery installed in about three minutes, and drive away. This approach sidesteps the range anxiety that comes with traditional charging, but it only works if you live or travel in areas with Nio swap stations — currently limited to China and Singapore.

Key Takeaways

  • The ET7 offers up to 1,000 miles of range through battery swapping, which takes about three minutes at a Nio swap station instead of hours of charging.
  • Nio's battery subscription model lets you pay monthly for battery access rather than buying the battery outright, reducing the upfront purchase price.
  • The car is only sold in China and Singapore as of now, so it is not an option for buyers in North America or Europe.
  • Pricing starts around 528,000 yuan in China, and the actual cost depends on whether you buy or lease the battery separately.
  • The ET7 competes with other Chinese luxury EVs like the BYD Han EV and XPeng P7, not with Tesla or traditional luxury brands in Western markets.

How Nio's battery-swapping system works and what it costs

Nio operates a network of battery-swap stations where you pull in, a robotic arm removes your depleted battery and installs a fully charged one, and you leave — all in roughly three minutes. This is fundamentally different from plugging in to charge, which takes 20 minutes for a fast charger or several hours for a home charger. The swap stations are concentrated in major Chinese cities and along highways between them; as of 2024, Nio has over 1,000 swap stations in China.

The battery itself is not always included in the purchase price. Nio offers three options: buy the battery outright (most expensive), lease the battery monthly (lower upfront cost), or use a pay-per-swap model where you pay a fee each time you swap. Monthly battery leases in China typically range from 980 to 1,480 yuan (roughly $135 to $205 USD), depending on the battery size and your subscription tier. This structure means two ET7 owners with the same car can have very different total costs depending on how they handle the battery.

Range, charging, and real-world driving distance

The ET7 comes in three battery sizes: 75 kWh, 100 kWh, and 150 kWh. The 75 kWh version offers around 405 miles of range, the 100 kWh offers roughly 540 miles, and the 150 kWh reaches approximately 1,000 miles on a single charge. These are manufacturer estimates; real-world range depends on driving conditions, speed, weather, and how much you use the air conditioning or heating.

If you do need to charge at home rather than swap, the ET7 supports DC fast charging at public stations and slower AC charging at home. A DC fast charger can add 200 miles in about 30 minutes, though charging speed slows as the battery approaches full capacity. Home charging with a standard wall outlet takes much longer — typically 10 to 15 hours for a partial charge. The advantage of the swap system is that you rarely need to wait for a full charge; you just swap when the battery runs low.

Interior features, performance, and driving experience

The ET7 is positioned as a luxury sedan, so it comes with a high-resolution touchscreen, a semi-autonomous driving system called Nio Pilot (similar to Tesla's Autopilot), and premium audio. The interior uses leather and wood trim, and the car offers heated and cooled seats. The steering wheel and dashboard layout are designed for Chinese drivers, so controls and menus are optimized for the Chinese market.

Performance-wise, the ET7 accelerates from 0 to 60 mph in around 3.9 seconds in its dual-motor version, which is competitive with luxury EVs like the Tesla Model S. The single-motor version is slower but still quick. The ride is smooth on highways, and the low center of gravity (thanks to the floor-mounted battery) keeps the car stable in corners. Noise levels are low, as with most electric cars, since there is no engine rumble.

Warranty, maintenance, and long-term ownership costs

Nio offers an eight-year or 120,000-mile warranty on the battery and drivetrain in China, which is longer than many Western automakers. Since the ET7 has no oil changes, spark plugs, or transmission fluid, maintenance is mainly tire rotation, brake fluid checks, and software updates. If you lease the battery, Nio covers battery degradation and replacement, so you do not pay extra if the battery loses capacity over time.

If you own the battery outright, you are responsible for replacement if it fails after the warranty expires. Battery replacement costs are not published by Nio, but based on industry standards, a replacement battery could cost $10,000 to $20,000 USD equivalent. This is why many owners choose the monthly lease option — it shifts the long-term battery risk to Nio. Over five years, the monthly lease payments add up, but you avoid the risk of a large unexpected bill.

How the ET7 compares to other electric sedans

In China, the ET7 competes directly with the BYD Han EV, XPeng P7, and Li Auto models. The BYD Han EV is cheaper and offers good range but lacks the luxury interior and semi-autonomous driving features. The XPeng P7 is closer in price and features but does not have battery swapping. Li Auto focuses on extended-range hybrids rather than pure electric cars, so it appeals to buyers worried about charging infrastructure.

Outside China, the ET7 does not have direct competitors because it is not sold in those markets. If you are shopping for a luxury electric sedan in North America or Europe, you would compare the Tesla Model S, BMW i7, Mercedes EQS, or Lucid Air instead. Those cars rely on traditional charging networks and do not offer battery swapping. The ET7's main advantage — the swap system — only matters if you live where swap stations exist.

Availability, import restrictions, and future plans

The ET7 is manufactured in China and sold primarily in the Chinese domestic market. Nio has also launched sales in Singapore and announced plans to enter Norway, Germany, and other European countries, but these rollouts are gradual. As of 2024, the car is not sold in the United States, Canada, or Mexico, and there are no confirmed plans to bring it to North America.

Importing an ET7 to the United States is technically possible but impractical. The car does not meet U.S. safety and emissions standards, and the battery-swapping infrastructure does not exist outside China and Singapore. Additionally, U.S. tariffs on Chinese vehicles and parts make importing expensive. If you are in North America and interested in a luxury electric sedan, you would need to look at domestically available options.

Frequently Asked Questions

Can I buy a Nio ET7 in the United States?

No. The ET7 is not sold in the U.S. and does not meet American safety or emissions standards. Nio has not announced plans to enter the North American market. If you want a luxury electric sedan in the U.S., you would need to choose from Tesla, BMW, Mercedes, Lucid, or other brands already selling here.

How much does a battery swap cost each time?

Nio does not publish a per-swap fee in U.S. dollars, but in China, swap costs vary by subscription tier and battery size. Most owners choose a monthly lease (roughly $135 to $205 USD equivalent) rather than paying per swap. The exact cost depends on your location and Nio's current pricing in that region.

What happens if I drive outside of China or Singapore?

You can still drive the car, but you lose the main advantage of battery swapping. You would need to rely on DC fast charging at public stations, which is slower and less convenient. Swap stations are only in China and Singapore, so the battery-swapping feature only works in those countries.

Is the ET7 more reliable than Tesla or other luxury EVs?

Nio is a newer brand than Tesla or traditional luxury automakers, so long-term reliability data is limited. The ET7 has received positive reviews for build quality and performance in China, but it has not been tested over decades like established brands. Warranty coverage is competitive, but real-world durability over 10+ years is still unknown.

Can I lease the battery instead of buying it?

Yes. Nio offers monthly battery leases as an alternative to buying the battery outright. This lowers the upfront purchase price and shifts battery replacement risk to Nio, but the monthly payments add up over time. The choice depends on whether you plan to keep the car long-term and how much you drive.
