To that end, Mazda says the Skyactiv-D 2.2 will deliver 168 horsepower and a stout 290 pound-feet of torque. EPA fuel economy numbers are estimated at 27 miles per gallon city, 30 mpg highway and 29 mpg combined. The engine will only be available in the CX-5's top Signature trim with standard all-wheel drive, starting at $41,000 plus $1,045 for destination ($1,090 in Alaska).

Disappointingly, however, those fuel efficiency numbers aren't far off what the base model's current 2.5-liter gas four-cylinder delivers. For comparison's sake, the CX-5's base Skyactiv-G engine generates 187 hp and 186 pound-feet of torque (admittedly at 4,000 rpm, twice the engine speed of the diesel at torque peak) and is rated at 24 mpg city, 30 mpg highway and 26 mpg combined in matching AWD spec.
