Carefully revised but not radically different from the 2012 model, the new Altima sedan's made one major change. This time around, it's available only with a continuously variable transmission, no conventional automatics or manuals at all. It's a choice made for fuel efficiency and build simplicity, but Nissan's made at least one improvement to address the typical CVT complaints of sluggish response: on V-6 versions, the CVT gets paddle controls and automatic-like programmed "gears."
Both the four- and six-cylinder engines return, and both promise better gas mileage in combination with the CVT. The four-cylinder model is estimated at 38 mpg highway, Nissan says, a few miles per gallon higher than today's leaders, cars like the Hyundai Sonata and Kia Optima, both rated at 35 mpg highway.
Nissan's also working on a hybrid Altima, this one designed in-house, using the four-cylinder and a supercharger coupled to batteries and motors, but it won't arrive in the 2013 model year.
In a more conservatively styled interior, Nissan's updated both the Altima's safety equipment and its infotainment systems. Bluetooth is now standard, and the optional navigation system now has a larger LCD display. Blind-spot monitors and lane-departure warning systems will be available, and a wide-angle rearview camera is also on the options list.
While the sedan's new for 2013, the two-door Altima Coupe will be carried over for one more model year. Beyond that, Nissan says only that it doesn't discuss future model plans.
