Cadillac sales are growing at the fastest clip since the Reagan administration, in large part because of China. Cadillac’s global sales this year through July were up 23%, beating its premium-car peers. In China, the world’s biggest auto market and site of one of every four sales, Cadillac through July sold 69% more vehicles than a year earlier. It was the first time Cadillac sold more vehicles abroad than at home, The Wall Street Journal reports. By tripling its China sales in five years, Cadillac has vaulted past Lexus, Land Rover and Volvo to become the country’s No. 4 luxury player, according to research firm LMC Automotive. Cadillac remains far behind the leading premium brands, in China as elsewhere. Chinese luxury-car buyers flock overwhelmingly to a mighty trio from Germany, so prominent the car-conscious call them simply “B-B-A”: BMW, Benz and Audi.
