Qin PLUS DM-i is a compact car under BYD.  The 120km high-end version can accelerate from 0 to 100 km/h in 6.3-6.5S (due to the original tire slipping at the start, it was achieved after the tire was replaced).  The power performance is far superior to the same level.  After the 2023 Champion Edition, the chassis shock absorption of the models has been re-tuned by famous teachers.  On the basis of the unchanged chassis structure, the torsion beam has been used to achieve a texture comparable to that of independent suspension, and the comfort and handling have been greatly improved compared to before.  The entire series is equipped with NFC Bluetooth key, mobile phone remote control, keyless entry for the front door, and 6 airbags as standard.  The high-end models are equipped with L2 assisted driving, mobile phone remote control driving, co-pilot electric seat, dual-zone constant temperature air conditioning, seat heating, multi-color ambient lights and other cross-level configurations to meet consumers' desire for comfort and safety.
