After years of teasing, which again is gaining momentum with the 6, Mazda has finally released its diesel four-cylinder in the United States. It is currently available only in the range-topping all-wheel-drive CX-5 Signature. The sequentially turbocharged 2.2-liter inline-four is rated at 168 horsepower and 290 lb-ft of torque.
On our 75-mph highway fuel-economy test, which is conducted over 200 miles, the CX-5 diesel achieved 34 mpg, 4 mpg better than the EPA estimates for the SUV. However, it didn't shine as brightly in daily driving, where during its first 400 miles in our hands it burned one gallon of diesel fuel every 25 miles. The EPA rates the AWD CX-5 diesel at 28 mpg combined, 27 mpg city, and 30 mpg on the highway.
