Nissan is preparing the all-new fifth generation Nissan Altima which is due to be launched late 2012 as a 2013 model year. These latest spy photos taken in the U.S. show the advanced stage of development with camouflage trimmed down to show the full body plus some design details.

Just like the current Sentra, Altima and Maxima model lineup, Nissan is looking to bring even greater design cohesion to the latest generations models. Already on this Altima prototype we can see the pinched grille from the all-new 2012 Versa as well as a more pronounced character line from the Maxima. Moreover, the Altima prototype looks to be showing an even more pronounced four-door coupe design (e.g. Mercedes CLS-Class, Audi A5 Sportback) than the current model as the roof/rear glass slope extending down into the luggage lid is less vertical.

The four-cylinder and V6 engines will remain the same but will become slightly more efficient and powerful. However, one major powertrain change will take place for the Altima hybrid. Developed in-house, the fuel-efficient powertrain is based on the system used in the Infiniti M35h. It will feature a twin-screw supercharged 2.5-liter four-cylinder engine, an electric motor and a lithium-ion battery. According to Nissan, the new supercharged hybrid engine will have the same output as Nissan's notorious 3.5-liter V6. This new hybrid engine configuration mated with a new continuously variable transmission which promises to improve fuel efficiency by as much as ten percent will eventually spread throughout the Nissa and Infinti model lines in years to come.
