DETROIT — General Motors executives on Monday chose a former Cadillac and Saab USA executive to fill the role as product marketing director for Buick. John Schwegman, U.S. marketing vice president for Buick GMC, appointed Roger McCormack to the role effective immediately.

Most recently, McCormack had been U.S. vehicle marketing director for Cadillac. He had held that post since November 2008.

The automaker recounted that McCormack joined GM back in 1989 as a field manager for Chevrolet Motor Division based in St. Louis, Miss. He has held numerous leadership positions in product development, marketing and market analysis.

As U.S. vehicle marketing director for Cadillac, McCormack also was responsible for Hummer and Saab, handling strategic and tactical marketing, product, pricing and incentive initiatives. 

Prior to that assignment, McCormack was the marketing director for Saab USA.

In his new role, GM indicated that McCormack now is responsible for brand marketing strategy and product planning for all Buick products. That marketing task includes strategy for the newest unit from the brand, the 2011 Buick Regal midsize sport sedan. That vehicle arrives at domestic dealerships this spring. 

"Roger brings a wealth of product and marketing experience to the job, and clearly understands the luxury automotive business, having spent time at Cadillac, Hummer and Saab," Schwegman noted.

"His expertise will be invaluable in continuing the transformation of Buick," Schwegman added.
