Hybrid Power From Nissan
Nissan's 2008 Altima Hybrid has a classification in the United States as an Advanced Technology Partial Zero Emission Vehicle (AT-PZEV). The vehicle's powertrain is a combination of a 158 hp 2.5L DOHC 16-valve 4 cylinder and a 40 hp permanent magnet AC synchronous electric motor. This gives a net hybrid system total power of 198 hp. The car derives its hybrid technology from Toyota, as Nissan has licensed this technology from Toyota and purchased some of the hybrid components from them.
When applying the brakes, there is regenerative braking to charge the nickel metal hydride battery, which is rated at 40 hp (30 kW) and 244.8 V. The transmission is an electronically controlled continuously variable type (eCVT), that uses a planetary gear power split device (PSD) coupled to a steel drive belt that transfers electric power to the front wheels. The PSD balances the power delivery between the high output electric motor and the gasoline engine. Nissan indicates an EPA overall 35 mpg city / 33 mpg highway figure for the fuel economy.
The Altima Hybrid is only available in the United States and sold in just eight U.S. States: California, New York, Massachusetts, Connecticut, Vermont, Rhode Island, Maine and New Jersey.
