Nissan’s Altima falls into a few of the same situations as the Honda Accord. Not only are dealers still selling a mixture of 2012 and 2013 models (the all-new 2013 Altima first reached dealers in late June), but one of the Altima variants doesn’t pass the 30-mpg highway sniff test – 2012 Altima V-6 models earn a 27-mpg rating from the EPA, while the four-cylinder posts a 32-mpg score.
Still, six-cylinder cars are far from the majority of Altima sales thus far in 2012. Intellichoice says 93 percent of Altimas sold this year are four-cylinders, while V-6 models make up the remaining seven percent. However, 2013 Altima V-6 models are rated at 22/31 mpg (city/highway), allowing the thirstiest Altima to finally enter the 30-MPG club.
