But unlike those best forgotten mills of the late-1970s and early 1980s, this one packs much greater refinement and higher fuel efficiency, not to mention double the power. Specifically, this little powerhouse cranks out 310 hp and up to 320 pound-feet of torque and still rates up to 26 mpg combined.
