UK vehicle sales tumbled in January, with the broader market contracting 4.6% year-on-year to 133,571 units. Among major brands, Tesla's car sales performance proved particularly weak—the American automaker saw registrations plunge 57.2% to just 647 electric vehicles, marking a significant setback in the British market. In stark contrast, China's BYD bucked the downward trend, expanding car sales by 20.9% year-on-year to reach 1,326 units, underscoring the intensifying competition in UK automotive sales between traditional EV leaders and emerging Chinese competitors.
