Overseas production by South Korea's leading carmaker Hyundai Motor Co. and its corporate cousin Kia Motors Corp. touched record-high numbers in March on the back of a boost in output in their factories in Turkey and China, data showed Sunday.

The combined number of cars produced abroad by the carmaking duo under Hyundai Motor Group came to 401,784 units in March, up 5.2 percent from a year earlier, according to the data compiled by the Korea Automobile Manufacturers Association.
