NEW YORK —It seems like we've been waiting forever, but the wait is finally over. Mazda has finally launched a diesel version of the CX-5 for the U.S. market, unveiled at the 2019 New York International Auto Show. Specifically, the 2.2-liter Skyactiv-D turbo-diesel engine will be offered in the higher-end CX-5 Signature AWD, part of what Mazda calls its "path to premium," as the company continues to set its sights on some of the more expensive competition. The Skyactiv-D 2.2 makes use of a sequential twin turbocharger that employs a smaller turbocharger first at low rpm for quick throttle response, after which a valve opens to spool up a larger turbocharger at higher rpm. Mazda says this provides "smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque." Mazda estimates the output of the engine to be 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm. The engine has a rev limit of 5,500 rpm. As of right now, it's only in the all-wheel-drive version and only in the Signature trim level. As such, it gets a ho-hum EPA fuel economy rating of 27 mpg city, 30 highway and 28 combined. We previously saw fuel economy figures for a potential front-drive diesel CX-5 getting just slightly better fuel economy, at 28 city, 31 highway and 29 combined, but no word yet on if and when that'll be made available. The mediocre diesel fuel economy, while expected given the midstream shift from one emissions strategy to another, is particularly disappointing in context. The non-turbo CX-5 AWD, which makes 187 hp and 186 lb-ft, gets 24 city and 30 highway for 26 combined mpg – just 3 mpg less in the city and 2 mpg less overall than the diesel. The much more powerful CX-5 Turbo, which makes 250 hp and 310 lb-ft, gets 22 city, 27 highway, and 24 combined. Mazda is taking pre-orders for the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 starting now, at an MSRP of $42,045, including $1,045 in destination fees. We have to point out that this is a sizable jump in MSRP from a CX-5 Signature AWD with the more powerful turbo engine, which lists for $38,235 – a $3,810 difference in fact. Given the lackluster fuel economy and considerable decrease in power and torque, we're concerned that the diesel may be a tough sell at this sort of premium.

The Miata: making everything a new experience and turning low-beam headlights into high-beams since 1989. That's what happens when you're basically sitting on the ground, something I've become intimately familiar with when driving our long-term 2016 MX-5 Club. I am not a tall person. Far from it. In most cars I drive, I crank the seat height up close to maximum as soon as I get in. That's easy in the Miata because there's no height adjustment at all. Couple that with the facts that the seat is thin and the car barely hovers off of the pavement, and my eyes end up sitting at the height of most car's exhaust systems. That results in a lot of examining other cars' bumpers in traffic. And one day recently, it almost led to me missing my exit from Interstate 94, part of the route I take every day to work. Everything just looks different from down here – it is quite literally a different point of view from what I'm used to. And then there's the issue of night driving. When you're this low down and stuck in traffic, the headlights of cars following look extremely bright (and incredibly close). They're not, of course, you're just lower than every other driver on the road so it seems like you're staring down high-beams in the rearview mirror. I still love the Miata. It's just not the best commuter vehicle, which should come as a surprise to precisely no one. But when a hole opens up in traffic, the Miata and I are the first to fill it. I just hope the other cars see me. Related Video: Mazda Long-Term Garage Convertible Lightweight Vehicles Performance

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.
