Nissan North America Inc. will unveil the ’07 Nissan Altima at the upcoming New York auto show.

For the next-generation of Nissan’s best-selling car, the midsize sedan moves to a new “D” platform that the auto maker says gives the vehicle improved body rigidity.

The Altima’s suspension also is redesigned for better handling, Nissan says.

Nissan will offer a continuously variable transmission for the first time in the Altima. It can be mated to either of the Altima’s engines: a 2.5L 4-cyl. or the auto maker’s award-winning 3.5L V-6.

The new Altima goes on sale this fall in the U.S.

Nissan also will show its refreshed Maxima flagship sedan in New York.

For ’07 the Maxima receives a new front grille and hood, changed headlights, as well as different front and rear bumpers, side sills and wheels, and a new interior with higher-quality materials, Nissan says.

Nissan’s Xtronic CVT now is standard on all Maximas.

Also on hand at Nissan’s New York booth will be the refreshed Quest minivan, Sentra compact car and new Versa subcompact.
