U.S. electric-vehicle registrations rose 14 percent in April after a lackluster first quarter, thanks to automaker incentives in excess of $10,000 on some models. But Tesla's numbers continued to fall sharply and its share of the EV segment dropped below 50 percent, according to new-vehicle data from S&P Global Mobility.
