Sales of the first, the Xpeng Mona M03, began in August and quickly the car became Xpeng’s best-selling model. Then, in November sales began of XPeng P7+, and it marked a huge reset for the Shenzhen-headquartered start-up.

My test car was the Ultra-Long Range Max, which has the larger 76.3-kWh battery pack and a more powerful 230-kW motor. Range for WIRED's test version is claimed to be 450 miles using China’s urban driving-skewed and more forgiving CLTC test cycle.
