2019 Mazda CX-5 Diesel Review: Was It Really Worth The Wait?

2019 Mazda CX-5 Diesel
That the 2019 Mazda CX-5 Diesel is just now hitting showrooms now is a bit of a shock. For the better part of the decade, Mazda had promised a diesel engine for a US-market car -- in fact, it was originally destined for the Mazda6. But the Japanese automaker said calibration and certification issues were the original source of delays, and those issues were made even more complicated by the Volkswagen Dieselgate scandal, which not only increased government oversight of diesel fuel, but tarnished public perception of these powertrains.
So Mazda faces an uphill battle by launching a diesel-powered CX-5 in the year 2019. Outside of pickup trucks, diesel engines are now pretty scarce. And making things more complicated, Mazda`s Skyactiv-D engine is only being offered in the most expensive CX-5 trim. Does that make this more efficient CX-5 a worthy consideration, or is the diesel-powered Mazda basically dead on arrival?
Different with diesel
Any company deciding to install a diesel engine in a US-spec passenger car today is certainly going against the grain. Fittingly, Mazda is no stranger to doing just that, previously championing rotary and miller-cycle engine technologies. The result of Mazda`s diesel development work is a 2.2-liter twin-turbocharged I4 producing 168 horsepower and 290 pound-feet of torque. When equipped with the diesel, the CX-5`s tow rating jumps to 3,500 pounds -- a 1,500-pound increase over the gas-powered models. 
From a power delivery and harmonics standpoint, the CX-5`s diesel powerplant is very impressive. There`s some ever-so-slight diesel garble as you roll onto the throttle, with punchy thrust down low in the rev range. It`s also perfectly smooth while spinning up to the high-for-a-diesel 5,500-rpm redline, making quick work of highway on-ramp merges.
Being a diesel, Knsz.prz.edu.pl you would expect the CX-5 to pack some bladder-busting driving range, right? Unfortunately, that`s not exactly the case. With a six-speed automatic transmission and all-wheel drive, the EPA estimates the CX-5 Diesel to return 27 miles per gallon in the city and 30 mpg on the highway. I confirmed those numbers, easily averaging 30.1 mpg on tank of fuel under mostly highway driving.
