The powerplant is a very new hybrid system for Nissan, a supercharged 2.5-liter four-cylinder that's aided by a 15-kilowatt electric motor. Total output for this system comes up to 250 horsepower and 243 pound-feet of torque. That is equivalent to the V-6 Pathfinder's 260 horsepower and 240 pound-feet of torque. The real win comes in fuel economy. Nissan estimates the Pathfinder Hybrid at 25 mpg city and 27 mpg highway.
