BYD's Yangwang Altior luxury sedan to get suicide doors

BYD is pushing further upmarket with the Yangwang Altior, a new flagship executive sedan from its ultra-luxury brand. New details show it will feature rear-hinged suicide doors and a gemstone-style grille, and it may use solid-state batteries. Yangwang already sells the U7 sedan, U8 off-roader and U9 electric supercar, often debuting BYD's latest technology.
