Hyundai Motor said Wednesday it posted record-high sales and profits in the second quarter this year, largely buoyed by strong sales in key markets, including the US. The carmaker’s sales revenue surged by 17.4 percent to 42.2 trillion won ($33 billion) from a year earlier, surpassing the previous record posted in the fourth quarter last year. Operating profits exceeded the 4 trillion won mark for the first tim.
