Nissan Motor Co. Ltd. names Mark McNabb as head of its Infiniti global business operation.

Effective April 1, the former Mercedes-Benz U.S.A. executive will spearhead Infiniti’s global expansion, Nissan says.

McNabb had a 20-year career at Nissan before joining Mercedes in 2005 as vice president-marketing. He later was named vice president-sales operations.

Nissan says it will explain McNabb’s responsibilities further and detail the Infiniti business plan later this month.
