Tesla Inc. continues to post steep sales declines in Europe, where the Elon Musk-led automaker is ceding significant share to China’s BYD Co.

In both Germany and the UK — by far the two leading countries for battery-electric vehicle registrations in the region — Tesla’s July sales fell by more than half compared with a year ago, according to figures reported Tuesday. BYD, by contrast, more than quadrupled registrations in each country.
