It’s been a week since Nissan gave us a second look at the all-new 2013 Altima sedan in advance of its world premiere at the New York Auto Show in April, and we all know what that means. Yes, it's teaser video number three that offers us our first look at the mid-size sedan's rear end styling and the multi-angle tail lamps, which follow the design of the head lights. 
In a video celebrating the 30th anniversary of the Nissan Technical Center in Atsugi, the Japanese automaker accidentally showed a pre-production prototype of the 2013 Altima sedan without any camouflage. The find was made by Mike Magrath from Insideline who was able to capture a screen shot of the car before Nissan pulled out the video replacing it with a revised version (3.44 minutes into the clip) that displays a covered up prototype of the Infiniti JX crossover in its place. 
Nissan previously told us that the 2013 Altima will be the brand's first car to be offered with a new hybrid system, which combines a supercharged 2.5-liter gasoline engine with a compact CVT package incorporating a single motor and two clutches plus a lithium-ion battery.
