Vehicle registrations for the Elon Musk-led company fell nearly 48% to 9,774 units between April and June in the Golden State, compared with a similar period a year earlier, Cross-Sell said, as reported by Reuters. Registrations of Model 3, which is the cheapest vehicle in Tesla's lineup, fell 63% to 5,951 units. Total vehicle registrations fell across the 23 states, where the data was gathered, by approximately 49% to 18,702 vehicles. Registration data may not be a true representation of delivery numbers during the quarter as it takes almost 30 days for vehicles to be registered from the time they are sold in the United States, Reuters noted.
