City-level advanced driver assistance is becoming a mainstream feature in China's new-car market. In September, 30.3% of newly registered passenger cars—about 497,000 units out of 1.64 million—came equipped with city NOA (navigation on autopilot for urban roads), according to data from Chinese outlet D1EV. This is the first time the penetration rate has exceeded 30%.
Model Y leads, but the pack is tight
The Tesla Model Y topped the city NOA installation chart in September with 45,000 units, nearly three times the second-place Xiaomi SU7. The Model Y's strong month was boosted by a 10,000 yuan (about $1,400) cash discount and a five-year zero-interest loan offer. However, the gap between second and twentieth place was narrow: the second-place model's installations were only 2.3 times those of the twentieth, and the difference between the 19th and 20th spots was just six units.
Among the top 20 city NOA-equipped models, 12 were SUVs longer than 4.9 meters, accounting for 48% of sales. Ten were new models launched this year, and three were refreshed versions, together representing 54% of the top 20's sales.
Hit models fade faster
The ranking is volatile. In January, the Xiaomi YU7 and Aito M7 led with 37,834 and 25,017 units, respectively, but by September the YU7 had dropped to sixth and the M7 fell out of the top 20. Only four models—Tesla Model Y, Xiaomi YU7, Nio ES8, and Li Auto i6—stayed in the top 20 throughout January–September, and only the Nio ES8 kept monthly sales fluctuations within a factor of two. The shelf life of hit models has shortened from years to quarters.
In January, 69.0% of city NOA-equipped new cars came from the top 20 models; by September, that share had fallen to 48.8%. As more models offer the feature, it is spreading across the market rather than concentrating in a few best-sellers.
City NOA, once a feature of 500,000-yuan luxury cars, is now standard in the 200,000-yuan segment and is moving into the 150,000-yuan range. Leapmotor's A10 starts at 86,800 yuan (about $12,200) for the smart-driving version, breaking the 100,000-yuan barrier, and has topped its segment for six consecutive months since April. The MG MG07 smart-driving version starts at 118,900 yuan (about $16,700), and the Xpeng M03 at 129,800 yuan (about $18,300).
Willingness to pay varies by price
In the third quarter, 57 models offered both city NOA and non-NOA versions, with 44.7% of buyers choosing the NOA version. However, these buyers represented only 6.5% of all new-car registrations in the quarter, meaning most consumers are not yet paying extra for the feature.
For models priced above 200,000 yuan, city NOA is effectively standard—all 14 such models in September had 100% take rates (Tesla counts hardware-equipped cars). Below 200,000 yuan, the picture is mixed: Baojun's Huajing S offers it across the range, Xpeng's MONA M03 and L03 and MG's MG07 see take rates above 70%, while Fangchengbao's Titan 7 and Leapmotor's A10 are below 50%. The extra cost for city NOA is typically around 10,000 yuan, or about 8% of the vehicle price.
BYD's DiPilot C, currently not counted as city NOA, is planned to receive an over-the-air update to a map-free "quasi-city pilot" in December. If it meets full-scenario standards, BYD's volume models could enter the ranking for the first time via software upgrades, provided battery production keeps up.
D1EV's data is based on insurance registration figures, counting only domestic sales and including hardware-equipped models that require paid activation.
