After several delays, Mazda Motor Corp. is adding a diesel variant of its CX-5 SUV/crossover vehicle in the U.S.
Initially, the 2.2-liter 4-cylinder Skyactiv-D powerplant (pictured) will be available only in the top-end Signature trim line of the CX-5 with all-wheel drive. The diesel-powered model will start at $42,000, about $2,800 more than a comparable CX-5 Signature with a 2.5-liter gasoline unit.
With an estimated U.S. Environmental Protection Agency fuel efficiency rating of 28 mpg, the diesel mill is nearly 8% more fuel efficient than its gasoline counterpart. But the Skyactiv-D generates only 168 hp and 290 lb-ft of torque, compared with the 2.5-liter unit’s 250 hp/310 lb-ft output.
Featuring a two-stage twin turbocharger with variable turbine geometry, the Skyactiv boasts a diesel-best compression ratio of 14.0:1. The low compression ratio decreases engine temperatures and pressure, which Mazda says improves the air/fuel mixture and reduces emissions of oxides of nitrogen and soot.
Mazda says the Skyactiv-D can meet most global emissions regulations without using aftertreatment devices. In the U.S., however, the CX-5 diesel will be fitted with a selective catalytic reduction system.
Mazda has long offered diesel engines on vehicles it sells in Europe and Asia. But the Skyactiv-D application in the CX-5, which was certified by the EPA last year, will be the first time the carmaker has sold a diesel-powered car in the U.S. The company also is working on a diesel option for the Mazda6 sedan in the U.S.

Mustang Changes for 2018
On Tuesday Ford unveiled—using the social media channels of actor Dwayne Johnson (this has got to unnerve some of the auto buff book editors)—the 2018 Mustang, which has undergone some modifications: under the hood (the 3.7-liter V6 is giving way to a 2.3-liter EcoBoost four, and a 10-speed automatic is available), on the dash (a 12-inch, all-digital LCD screen is available for the dashboard), at the tires (12 wheel choices), on the chassis (MagneRide damper technology is being offered with the Mustang Performance Package), and on the exterior (three new paint colors). And while on the subject of the exterior, there are some notable changes—a lower, remodeled hood, repositioned hood vents, new upper and lower front grilles, LED front lights, revised LED taillamps, new rear bumper and fascia.
