Over the next 15 months, Nissan will be rolling out 5 all-new models. As the brand strives to take over 10 percent of the total market share in the next few years, it has got a lot riding on these new cars, which will make up the bulk of Nissan’s sales. First up is the new 2013 Altima, which we were invited to drive in Nashville, where the company’s North American headquarters are located. For us, this opportunity to drive the new sedan is like a small glimpse into the future, so we headed down to Music City to try out this automotive crystal ball.
