2019 Mazda CX-5 Signature Diesel First Drive Review | A tardy inessential

We were suspicious of the much-delayed Mazda CX-5 Diesel when it finally arrived at our office late this summer. Had it surfaced four or even two years ago, we might’ve been more bullish, but at least we werenÂ’t cynical — yet. Even the Volkswagen Dieselgate crisis couldnÂ’t turn our hearts against the CX-5 Diesel. We already like the CX-5, after all, we also like the eager torque, quiet ride and excellent fuel economy the Skyactiv-D engine would surely provide. But then we got the EPA ratings for the the CX-5Â’s diesel engine: 27 mpg city and 30 highway. Granted, thatÂ’s in an all-wheel-drive vehicle, but itÂ’s a serious disappointment. The turbocharged, gasoline-powered 2.5-liter I4 in the CX-5 Signature gets 24 combined mpg, while offering up to 250 horsepower and 310 pound-feet of torque. The diesel version is down 82 hp (at 168) and 20 lb-ft (at 290), while elevating fuel economy to 27 city, 30 highway and 28 combined. The non-turbo gas motor in lesser AWD trims narrows the gap to just 2 combined mpg in favor of the diesel. So whatÂ’s the selling point for the Skyactiv-D? Mazda says itÂ’s a premium experience, and thatÂ’s why itÂ’s only available in the top trim level. ItÂ’s easy to flinch at that, but it makes some sense, when you look at other diesels in the U.S. market The Signature trim of the CX-5, as with the Mazda6 weÂ’ve come to adore, is good enough to target the lower end of, say, Audi customers who are looking to get a bit more content for the buck. These might also be the same people whoÂ’ve come out of a TDI vehicle and are already sold on the diesel experience. From the first squeeze of our right foot, the diesel CX-5 makes a good impression. In town, we diced our way through Woodward Avenue traffic, made easy mostly by the CX-5Â’s relative small size and agility. There is one point in the throttle tip-in when the engine sounds particularly growly, and somehow more massive than its 2.2 liters of displacement. The illusion began to crumble when we reached our first highway entrance ramp. Putting our foot to the floor, we got the quick first hit of growly torque, followed by Â… well not much. This engine begins to run out of steam as it climbs the rev ladder. ThatÂ’s not totally unexpected, but it was definitely disappointing. Furthermore, as Assistant Editor Zac Palmer points out, “By opting for the diesel, you add 115 pounds to the curb weight (now 3,940 pounds) of a comparable 2.5-liter turbo (3,825 pounds).

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

At least 15 states jockeying for Toyota and Mazda factory jobs

Just a few weeks ago, Mazda and Toyota announced a partnership that would lead to an all-new $1.6 billion plant here in the United States. The plant will build EVs and is expected to employ roughly 4,000 people directly while creating thousands of indirect jobs through suppliers, shipping and more. The Detroit Free Press reports that as many as 15 Midwestern and Southern states are understandably interested in striking a deal with the automakers. Most of the states already have ties to the auto industry. While the Midwest has traditionally been home to auto manufacturing in the United States, in the past 25 years or so, the South has made a big push, offering tax incentives and a union-free workforce. Alabama alone is home to facilities from Honda, Hyundai, Mercedes-Benz and Toyota. Others house a burgeoning tech or manufacturing industry ripe for the picking. Freep breaks down the pros and cons for each state, with much of the focus being on supply chains and a reliable and plentiful workforce. The latter is of particular concern in states like Alabama and Michigan that already have a big auto industry. Toyota may feel those areas have already been tapped for talent. Most of the states are along or adjacent to Interstate 75 and its extended roots, so others like Texas and Iowa will have to fight hard if they want this facility. It's only been a few weeks, though. With manufacturing jobs in such great demand and elected officials eager to show they're seeking them for their states, it wouldn't be surprising if a few more joined the fray.
