Tesla's UK new car sales plummeted over 45% in May, selling 1,758 units compared to 3,244 in the same month last year, while overall new car registrations rose by 4.3%. Despite this decline, Tesla remains the best-selling battery electric vehicle brand in Britain for the year to date. In contrast, BYD's sales doubled to 1,388 units, marking a significant shift in the European EV market, where Tesla has fallen to 11th place in rankings. The broader UK battery electric vehicle market grew by 28%, driven by increased supply and consumer confidence.
