Nissan Altima Sedan

From Nissan press: For 2010, Altima takes another leap forward with a major revision to its fourth-generation design with new exterior styling, refined interior treatments and enhanced technology and entertainment features -- including an advanced available Nissan Hard Drive Navigation System with 9.3GB Music Box hard drive for digital music storage and playback and standard 6.5-inch color touch-screen display.

The 2010 Altima Sedan is available in three well-equipped models designed to appeal to a broad range of buyer needs and budgets: the 2.5 CVT and 2.5 S CVT with standard 175-horsepower 2.5-liter inline 4-cylinder, and the 3.5 SR CVT with a 270-horsepower 3.5-liter V6. The 3.5 SR replaces the previous 3.5 SE model.

Altima is built on Nissan's advanced "D" platform, with Vehicle Dynamic Control (VDC) now standard on all models. The 2010 Nissan Altima also offers a range of comfort and convenience features, including available Nissan Intelligent Key with Push Button Ignition, Bluetooth® Hands-free Phone System with audio streaming and RearView Monitor.

Two powerplants are once again available in 2010. The 3.5-liter 24-valve DOHC V6 is rated at 270 horsepower and 258 lb-ft of torque and offers strong acceleration and a tuned, resonant sound quality. The V6 features minimized friction, superior cylinder head cooling and twin knock sensors.

Also available is a 2.5-liter DOHC 16-valve 4-cylinder producing 175 horsepower (170 hp CAL) and 180 lb-ft of torque (175 lb-ft CAL). It features a silent chain drive and a balancer system (with balancer changed to a center-mounted location for excellent NVH) that effectively negates vibrations without taking up much space -- combining ideal packaging and smoothness.

Both engines feature continuously variable valve timing, modular engine design, microfinished crank journals and cam lobes, molybdenum coated lightweight pistons and electronically controlled throttles. Altima's standard dual exhaust system is designed to reduce exhaust backpressure by 35% on the 4-cylinder and 50% with the V6 (over the previous generations). Both systems utilize large tube diameters and include dual chrome-tipped exhaust finishers.

Nissan's advanced Xtronic CVT, which is designed to create a true synergy between engine and transmission with smooth, responsive, fluid-feeling performance and efficient operation, is standard on all models. The CVT has been tailored specifically for use with the Altima.

The V6 CVT features a "Sport" mode controller with a high-speed central processing unit and Adaptive Shift Controller with adaptive logic for fast shifting in both normal and manual modes. The adaptive logic feature delivers the best shift pattern based on the driving environment and driver's actions. It utilizes 700 programmed algorithms to adjust to differing conditions, such as uphill or downhill driving, as well as adapting to three styles of driving -- economy, normal and sporty.
