Cramer-Krasselt was named an advertising agency for North America by Porsche. It will get a $40 million (EUR29.4 million) glamour account.
Cramer-Krasselt will handle creative and media planning and buying for Atlanta-based Porsche Cars North American, Inc., a subsidiary of the German luxury automaker.
The company chose Cramer-Krasselt after a four-month review of 20 agencies.
"Our decision to go with Cramer-Krasselt was based on seeking new and innovative approaches to marketing our unique products to a difficult-to-reach audience," said David Pryor, the subsidiary's vice president of marketing in a statement.
It is a huge contract for Cramer-Krasselt, which has never handled a national automotive account.
The agency may be best known for its work with Corona.
Porsche chose Cramer-Krasselt over finalists Minneapolis-based Carmichael Lynch, its agency of record since 1999, SS+K of New York, and The Martin Agency, based in Richmond, Virginia.
"Everyone is thrilled," said Cramer-Krasselt's general manager Karen Seamen. "It's a fabulous piece of business."
It was the second big snare for Cramer-Krasselt in six days. The agency was also chosen by Bissell to market vacuum cleaners and other products.
