BYD says its new Denza Z9S is now the world’s longest-range electric car, citing a maximum figure of 683 miles, or 1,100 kilometers, on a full charge. The four-door sedan is offered in China from the equivalent of $47,100, according to the source, and pairs its headline range claim with a 102.3-kilowatt-hour lithium-iron-phosphate battery that is standard across the lineup.
Denza general manager Li Hui described the range figure as something “not meant to be remembered, but to be forgotten,” according to CNEVPost. His point was that the car is intended to travel far enough between charges that drivers may stop thinking frequently about plugging it in. The statement remains a manufacturer claim tied to the Chinese-market specification.
The Z9S will be sold in three range versions. The entry model is rated at 484 miles, or 780 km, while the middle version is listed at 571 miles, or 920 km. The top version carries the 683-mile, 1,100-km figure that BYD is using to support its longest-range claim.
All three numbers come from China’s CLTC test procedure. The source notes that this cycle places more emphasis on low-speed driving than high-speed cruising, which can produce higher range figures than the U.S. EPA test. It estimates that the longest-range Z9S could receive an EPA figure of around 480 miles, or 772 km, if it were tested in the United States.
That estimated result would remain below the Lucid Air Grand Touring’s EPA-rated 512 miles, or 824 km. The source also estimates that the Lucid could reach approximately 730 miles, or 1,174 km, under the CLTC procedure. The comparison shows that the Z9S claim depends heavily on which testing standard is used.
The Z9S uses BYD’s second-generation Blade battery. According to the source, charging from 10% to 70% takes five minutes, while a 10% to 97% session takes nine minutes. These figures are presented alongside the car’s long-range ratings as the main technical focus of the model.
The base Z9S uses a single electric motor rated at 496 horsepower, or 370 kW. Higher-specification versions use three motors and are rated at 1,193 hp, or 890 kW. The sedan also includes a roof-mounted lidar sensor, standard rear-wheel steering, an air body control system and BYD’s God’s Eye 5.0 assisted-driving system.
Inside, the Z9S follows the screen-heavy layout associated in the source with technology-focused Chinese electric vehicles. The model is being sold in China, where its quoted $47,100 starting price and CLTC figures define the current offer. The source does not identify another launch market, a confirmed U.S. plan or any scheduled EPA test, so comparisons with U.S.-rated models remain based on estimates rather than an official Z9S result.
