Nio (NYSE: NIO) said its NOP+ (Navigate on Pilot Plus) feature now covers 99 percent of the Chinese mainland's cities, or 726.

That's an increase of 120 cities from February, the electric vehicle (EV) maker announced today on Weibo.

To date, NOP+ has completed more than 1 million kilometers of road verification, Nio said.

In a retweet of Nio's Weibo post, Harry Wong, Nio's head of intelligent driving products and experience, said the 726 cities refer to those that have completed the road verification, excluding "Unlimited Mode".

Currently, all Nio stores in China allow customers to experience the feature, Wong said.

Wong said on March 1 that NOP+ has an Unlimited Mode that allows the feature to be used on virtually any road in China.

At the time, he announced that Nio was recruiting pioneer users for NOP+'s Unlimited Mode, with the first available slots for 100 people.

NOP+ is Nio's ADAS (Advanced Driver Assistance System), which was initially available only on highways.

At the first Nio IN 2023 Innovation Day on September 21, 2023, Nio announced that NOP+ coverage has officially been extended from highways to urban roads.

Nio is relying on what it calls "group intelligence" to enable NOP+ to rapidly grow its coverage mileage in Chinese cities.

In the fourth quarter of last year, Nio launched an engineering test of the Unlimited Mode as a complement to the group intelligence validation mode, Wong said on March 1.

"Per the company, its latest NOP+ could be used outside of Greater China, further demonstrating its algorithm's ability to adapt to different traffic rules and driving scenarios," Morgan Stanley analyst Tim Hsiao's team said in a March 1 research note.
