The company produces and sells performance modifications, aftermarket auto parts, Shelby-oriented apparel, and replicas of classic older cars, such as a just-announced limited-edition 50th anniversary re-creation of the 1965 Shelby Daytona Coupe.
When Carroll Shelby died in 2012, the company vowed to carry on in his image, with new supercharged models pumping out 750, 850 and 1,000 hp.
But Cummings acknowledged that many overseas buyers face restrictions on the engine power normally associated with Shelby cars in America.
He said that in many cases, the overseas models will be equipped with Ford's smaller and more fuel-efficient turbocharged EcoBoost engines. A four-cylinder EcoBoost Shelby would yield 305 hp, or 345 hp with added tuning.
Cummings said Shelby American's global campaign has become possible because Ford has made the Mustang a global car. Ford began exporting the Mustang this year, thanks to a redesign that makes tweaking it for local regulations and technical preferences easier for 100 world markets.
Because the Mustang was redesigned for export, he said, Shelby's variations of the Mustang also can be adapted to world markets.
