Cadillac Gets Global Brand Chief

General Motors Co. has appointed Robert Ferguson, formerly the company's vice president for global public policy, to the newly created job of vice president of global Cadillac.

In his new job Ferguson oversees marketing, brand management and advertising for Cadillac worldwide. He reports directly to CEO Dan Akerson. GM says Ferguson will add responsibility for the luxury brand's global sales in 2013.

Don Butler was named global Cadillac marketing vice president in August 2011 but did not have corresponding sales or advertising duties. He is now the brand's U.S. marketing chief, reporting to Ferguson.

Ferguson, 53, spent 10 years at AT&T, most recently as head of the telecom's state legislative and regulatory affairs. He later joined Public Strategies, the business advisory firm, before coming to GM two years ago.

Ferguson's assignment is the latest effort by GM to promote Cadillac outside North America. The brand has begun its most extensive product upgrade in history and is determined to compete with such entrenched global luxury brands such as Audi, BMW and Mercedes-Benz.

GM communications chief Selim Bingol will add Ferguson's former duties under the title of vice president for global communications and public policy.
