"With all the buzz that comes with the (Detroit) Auto Show, the release of our Super Bowl advertisement, 'Get Happy,' and a full line-up of new and refreshed vehicles, Volkswagen is off to a solid start in 2013," said Jonathan Browning, CEO of Volkswagen Group of America, in a prepared statement. "While the economic conditions continue to be somewhat uncertain, we expect Volkswagen to achieve continued growth and to outpace the industry this year."
