Kia Motors America Inc. is on a roll. In 2012, the Korean automaker's Irvine, Calif., subsidiary reported all-time record sales nearly 15 percent above the previous year, and its legal team was a big part of keeping business running smoothly.

The company's legal department is known for its rigorous management of outside counsel, use of technology and diversity initiatives. Headed by executive vice president and general counsel John Yoon, who joined in 2000, the legal team counts seven attorneys in Irvine. The department oversees the automaker's dealer-related legal matters.
