Tesla Inc. saw its first increase in vehicle deliveries from its Shanghai factory this year, with the US automaker potentially buoyed by the clearance of regulatory hurdles for its advanced driver-assistance features.

Tesla's China-made electric vehicle sales edged up 0.8% in June from a year earlier to 71,599 units, snapping an eight-month losing streak, even as lower-cost new models from its Chinese rivals put growing pressure on the U.

Chinese EV maker Leapmotor and two ventures--Dongfegn Nissan and GAC Toyota broke their record of NEV wholesale sales in June, and Great Wall Motor, Nio, FAW Bestune, FAW Hongqi and Changan Mazda achieved their second-highest monthly sales on record, according to the CPCA.
