2010 Nissan Altima

Xtronic Continuously Variable Transmission (CVT)
Xtronic is Nissan's third-generation CVT. This computer-controlled stepless shifter helps improve performance, economy and emissions. In "Sport" mode, it even creates six "virtual" gears that closely approximate the response of a conventional manual gearbox.

Optional 2.5 SL Package
This fashionable extras group gives buyers who want a more fuel-efficient four-cylinder Altima 2.5 S virtually all of the main upscale trappings of a 3.5 SR, adding leather upholstery, power and heated front seats, a moonroof, dual-zone climate control with rear air vents, HomeLink universal garage-door opener and numerous lesser luxury touches.

The Altima's airy cabin has a contemporary appearance supported by nicely textured plastic, lots of stow space and numerous soft-touch surfaces that contribute to its welcoming character. White-on-black main gauges are easy to read, the ancillary controls and center-stack switchgear is logically arrayed and the Altima's generous glass area provides the driver with good sightlines to the outside world. The front buckets, although comfortable, could use a bit more lateral support. Even though the Altima skews to the smaller side of the official EPA "mid-size" category, its 60/40 split-folding rear bench seat can still accommodate two average adults or three kids while enhancing the flexibility and utility of its 15.3 cubic feet of trunk capacity.

Even a quick glance shows that the Altima is rich in Nissan family cues, most notably in its new grille, headlamp and taillamp treatments. However, the lines and contours of its crisply rendered sheetmetal display a bit more aggressive edge than you'll find in the Sentra or Maxima. A well-defined shoulder ridge complements bold flaring on fenderwells that house 16-inch 215/60 tires on 2.5 and 2.5 S models and 215/55 rubber on 17-inch cast-alloy wheels on the 3.5 SR.

Conventional Altima sedans offer the choice of an inline-4 or a V6. Both engines are made from lightweight aluminum, have four valves per cylinder and use continuously-variable valve timing to improve response and efficiency across their entire operating ranges. The 2.5-liter four develops a solid 175 horsepower and 180 pound-feet of torque while the 3.5-liter V6 raises those figures to 270 and 258, respectively. Nissan's Xtronic CVT (continuously variable automatic transmission), is the only transmission choice.
