Xpeng has boasted its P7 electric sports sedan car can travel the furthest on a single charge out of all the electric vehicles (EVs) sold in China.

The Chinese EV startup said that the country’s Ministry of Industry and Information Technology (MIIT) has officially rated the P7 as being able to travel 706 kilometers after testing the car under the New European Driving Cycle (NEDC) standards, according to a press release published Friday. The NEDC is a system used to assess a car’s mileage.

Xpeng attributed the cruising performance to the car’s latest-generation battery pack that provides an energy density of 170Wh/kg; its integrated electric driving system which produces higher efficiency; and its low-air resistance coefficient achieved through the installation of a semi-hidden wiper and low-resistance exterior mirrors and wheel rim covers.

The firm added that it uses aluminum alloy to produce the P7’s upper and lower control arms, steering knuckles and damper forks in order to further reduce the car’s weight.

Xpeng said that it will officially launch the P7 and start deliveries in China in the second quarter of 2020.

In January, China’s new energy vehicle sales nosedived 54.4% year-on-year to 44,000 units, marking the seventh consecutive month of decline.
