Schwab, 42, has worked at Land Rover for 14 years, most recently as marketing director in the United Kingdom. Her hiring at Aston will take effect Oct. 26.
"You're looking after an exceptional brand and it's a big responsibility," Schwab said in an interview. "It's an exciting time for a great brand and I feel really honored to be given this opportunity."
Schwab, a Louisville, Ky., native, will work out of Aston's Americas headquarters in Irvine, Calif., where she'll head operations for the U.S., Canada, Mexico and South America. The region makes up about 25 percent of Aston's annual global sales and has 46 dealers.
Those plans include boosting annual global sales to 15,000, up from 4,000 in 2014. To do this, the company is revamping and expanding its lineup.
The first new model in the company's pivot will be the DB11 -- a successor to the current DB9 -- that is expected to debut in 2016.
A new generation of Aston's smaller Vantage is expected after that. It will use V-8 engines and electrical architecture developed in conjunction with Mercedes-Benz's parent company Daimler AG, which bought a 5 percent stake in Aston in 2013.
An electric Rapide four-door will follow, and then the new DBX four-door crossover coupe will arrive by the end of the decade. The DBX is aimed at markets such as the U.S. and China, as well as female buyers, and will come in gasoline, plug-in hybrid and electric variants.
To keep up with its growing ambitions, Aston also plans to build a new production plant. Company CEO Andy Palmer has indicated Alabama is among the sites on Aston's short list. The company plans to announce the location this month.
Schwab replaces Julian Jenkins, who left Aston in August to become general manager of global business development for Rolls-Royce.
