On August 29, 2025, BYD officially launched the Qin L EV 545KM Yunnian edition at the Chengdu International Auto Show. Its official suggested retail price is RMB 139,800, and it also offers a limited-time Qixi Festival carnival price of RMB 129,800. The limited-time promotion will last until September 30. The newly launched Yunnian model features several upgrades over the existing top-of-the-line model, becoming the only model in its class equipped with both the Yunnian-C intelligent damping body control system and the TBC high-speed tire puncture control system.
The Qin L EV Yunnian model adopts Dynasty Network's latest "Loong Face" aesthetic design language. Its overall style is similar to the BYD Han EV, earning it the nickname "Little Han" from netizens. Three new colors, Sweet Pomelo Pink, Glazed Green, and Sea Crystal Blue, are now available, offering consumers more personalized options. In terms of dimensions, according to information filed with the Ministry of Industry and Information Technology, the Qin L EV measures 4720mm in length, 1880mm in width, and 1495mm in height, respectively, with a wheelbase of 2820mm, placing it in the mid-size sedan category. Compared to the DM-i version, the wheelbase has been increased by 30mm, improving rear passenger space.
2.1 Yunnian-C Intelligent Damping Body Control System
A key highlight of the new vehicle, the Yunnian-C system enhances vertical control, achieving a balance between comfort and sportiness. This system intelligently adjusts suspension damping based on varying road conditions, providing a more stable ride on bumpy roads, enhancing handling precision during sharp turns, acceleration, and braking, and effectively reducing body tilt and sliding during emergency avoidance.
2.2 TBC High-Speed Tire Blowout Stabilization System
To address the dangers of high-speed tire blowouts, the TBC system stabilizes the vehicle in three dimensions: horizontal, vertical, and vertical, limiting lateral deviation to within 75cm. Even in the event of a tire blowout at 140 km/h, the system can instantly intervene to help stabilize the vehicle.
2.3 Power and Range Performance
The Qin L EV Yunnian model is built on the e-Platform 3.0 Evo, featuring a rear-engine, rear-wheel drive layout. It is equipped with a 160kW motor and a 56.64kWh lithium iron phosphate blade battery pack, resulting in a range of 545 kilometers under CLTC conditions. The vehicle supports 30-minute fast charging (from 30% to 80%) and boasts an energy consumption of only 10.8kWh per 100 kilometers.

The Qin L EV Yunnian model competes directly with mid-size pure electric sedans such as the ARCFOX αS5 (starting at RMB 127,800) and Deepal SL03 (starting at RMB 129,900). With its Yunnian-C system, TBC safety technology, and comprehensive intelligent features, the Qin L EV Yunnian model demonstrates a strong product advantage among vehicles in its class.
For consumers seeking superior driving and safety performance, the limited-time price of RMB 129,800 makes the Qin L EV Yunnian a highly cost-effective option among mid-size pure electric sedans.
