Ford's (NYSE: F) 2015 Mustang was unveiled in a series of events all over the world last week. In six different cities on four continents, Ford hosted events featuring members of the Mustang's design team and senior executives, giving analysts and media members an up-close look at the new car and the thinking that went into its design. 

Our "Motor Money" team of Rex Moore and John Rosevear were front and center at Ford's New York event to take a close look and share their impressions of the 50th anniversary model of the Mustang. They also had the rare opportunity to get Ford CEO Alan Mulally, executive director of design Moray Callum, and Mustang chief engineer Dave Pericak to give their thoughts on the all-new pony.

So what's the verdict? The new Mustang may look a lot like the car it's replacing at first glance, but design chief Callum helped us understand why it's actually quite a bit different. In this video, shot live at the New York event, Rex and John ask Callum about the challenges of redesigning an iconic vehicle. Watch as Ford's chief designer explains the approach that he and his team took with the 2015 Mustang.
