AI Overview
If you value the lifetime warranty and winter charging efficiency of the three electric vehicles, and do not have high requirements for range and power, this car is worth considering; Otherwise, it is recommended to compare more.
- The first car owner can enjoy a lifetime warranty for the three batteries (battery, motor, and electronic control), but it must be maintained at an authorized BYD store, otherwise it may become invalid.
- Standard battery preheating, which can be preheated before winter charging to improve charging efficiency, but it will consume power and slightly reduce winter range.
- CLTC endurance 450 km, maximum power 100 kW, maximum torque 180 N·m， All are at a lower level in the same class.

Strengths and trade-offs
Key strengths
Three Electric Lifetime Warranty
The first car owner has a lifetime warranty for the three electric products, with a long warranty period and obvious advantages in the same level.
Battery preheating
Standard battery preheating ensures fast charging speed in winter and extends battery life.
Low power consumption per 100 kilometers
electricity consumption per 100 kilometers 11.4 kWh/100km, at a relatively high level among peers（P 91）。
Trade-offs
Strict lifetime warranty terms
Lifetime warranty requires maintenance at authorized BYD stores, otherwise it may become invalid; Second hand car buyers cannot enjoy it.
Battery preheating cannot be manually turned off
The battery preheating cannot be manually turned off, and sometimes it can be started without preheating, consuming power.
Weak power and range
maximum power 100 kW, maximum torque 180 N·m，CLTC endurance 450 km They are all at a lower level among their peers.
