Nissan Altima Hybrid
From Nissan press: Since introduction, the Altima Hybrid has stood out from other hybrids in its class with its balance of fuel efficiency and drivability. Now, for the 2010 model year, the Altima Hybrid adds a revised exterior, refined interior and upgraded audio and navigation system offerings.
The enhancements for the new model year, most of which are shared with the non-hybrid 2010 Altima Sedan, includes a revised front end appearance, new 16-inch wheel design, revised option package content, refined interior fabric and finishers and one new exterior color. Also offered is a new premium audio system that includes a 4.3-inch color display, USB port with iPod® connectivity, Bluetooth® Hands-free Phone System, MP3/WMA CD-ROM playback, XM® Satellite Radio (XM® subscription required, sold separately), and RearView Monitor; and a next-generation Nissan Hard Drive Navigation System with 6.5-inch VGA color display and 9.3GB Music Box for music storage and playback.
The 2010 Altima Hybrid continues to offer the efficiency and fuel economy of a hybrid drivetrain with the performance and excitement typical of any Altima, combining true driving pleasure, distinctive and sporty design and a quality-crafted interior with excellent fuel mileage. It has been certified to meet California emissions requirements and is sold in states that have adopted California emissions regulations: California, Connecticut, Maine, Massachusetts, New Jersey, New York, Oregon, Rhode Island and Vermont.
The Altima Hybrid powertrain mates a refined version of Nissan’s QR25 2.5-liter 4-cylinder engine and standard electronically controlled CVT with an advanced electric drive motor/generator that increases fuel economy while maintaining low tailpipe emissions. Altima Hybrid is rated as an Advanced Technology - Partial Zero Emissions Vehicle (AT-PZEV) and emits almost no evaporative emissions.
The advanced energy drive system shares duties between the gasoline-powered 4-cylinder and the emissions-free electric motor – allowing Altima Hybrid to run solely on electric power if appropriate, especially during stop-and-go driving. If extra performance is needed, the gasoline engine starts instantly and smoothly adds power as required.
Altima Hybrid is estimated to have a hybrid system net power rating of 198 horsepower (148 kW). EPA fuel economy is estimated at 35 mpg City and 33 mpg Highway. Combined with Altima’s standard 20-gallon fuel tank, the Altima Hybrid has a projected driving range of over 600 miles between fill-ups.
The Altima Hybrid utilizes regenerative braking technology to recharge the hybrid system’s batteries, meaning Altima Hybrid doesn’t have to “plug in” to maintain a sufficient store of electric energy.
In order to recharge the battery, a generator places resistance on the driveshaft during braking. Altima Hybrid’s Regenerative Brake System calculates braking force generated by brake pedal operation and controls the regenerative brake force to convert kinetic energy into electric energy, optimizing energy regeneration. The system converts the vehicle’s kinetic energy to usable electric energy that is stored in the system’s 244.8V Nickel Metal Hydride (Ni-MH) battery for eventual use by the electric motor.
Nissan’s proven QR25 4-cylinder engine features continuously variable valve timing, modular engine design, microfinished crank journals and cam lobes, molybdenum-coated lightweight pistons and electronically controlled throttle.
Helping provide smooth acceleration and maximize powertrain efficiency is Altima Hybrid’s hybrid system-specific eCVT, which works in conjunction with the Hybrid Vehicle-Electric Control Unit (HV-ECU) to determine which power source or combination of power sources will turn the wheels.
