( http://www.TFLcar.com ) The 2013 Nissan Altima is all new, except that in every noticeable measure the car remains very much unchanged. It still comes with the same two engine choices: a 2.5L and a 3.5L. Both engines are still mated to a CVT (continuously varying transmission) and in terms of interior space the new Altima is about the same size as the old Nissan Altima. So what's new? The 2.5 liter car gets 38 MPG on the highway and costs less and even weighs less. The new 2013 Altima also...but you know what...just watch this first drive TFLcar review to find out about the rest of the changes.
