A new test of the BYD Yangwang U7 reveals how extreme usage affects its battery performance, with capacity dropping by 1.3% after covering 30,000 kilometers and enduring over 350 rapid charges in just nine days. The accelerated wear-and-tear scenario—simulating aggressive driving and frequent fast-charging cycles—highlights real-world durability concerns for high-performance electric vehicles. While the decline is modest, the test underscores the trade-offs between speed, range, and long-term battery health. Results may offer valuable insights for owners prioritizing performance over gradual degradation.
