For the Hybrid version, Nissan Pathfinder's standard 3.5-liter V6 is replaced by a supercharged 2.5-liter gasoline engine and an electric motor paired with a compact Lithium-ion (Li-ion) battery. The 15 kW electric motor and gas engine work in tandem to provide performance similar to the conventional Pathfinder. The system is rated at 250 net horsepower and 243 lb-ft of torque – versus the 3.5-liter V6's 260 horsepower and 240 lb-ft of torque.
The hybrid system also uses a Nissan Intelligent Dual Clutch System (one motor / two clutch parallel system) that efficiently manages power from both the electric motor and the gas engine. Positioned between the gasoline engine and the next-gen Xtronic CVT® (where the torque converter would normally be), the motor also functions as a generator, conveying energy from the CVT to the battery upon deceleration. One clutch is installed between the gasoline engine and the electric motor, the other within the CVT.
Fuel economy is rated at 26 mpg combined, an increase of 24 percent over the standard Pathfinder. City fuel economy is 25 mpg, while highway mileage is estimated at 28 mpg (27 mpg 4WD). With the Pathfinder Hybrid's large 19.5-gallon fuel tank, the same as 3.5-liter V6-equipped models, driving range (highway) is estimated at more than 546 miles*.
Another key to the system's non-compromising design efficiency is the use of a space-saving Li-ion battery fitted under the 3rd row seat, preserving Pathfinder's unique 2nd row sliding functionality and easy access to the 3rd row. A regenerative braking system automatically recharges the battery by converting the vehicle's kinetic energy that would be otherwise lost in braking.
