2019 Mazda6 Skyactiv-D diesel caught in spy photos

We get it – we're a little sick of getting a few years of assurances that Mazda's much-anticipated diesel engine is just around the corner. First, it was going to go in the 2014 Mazda6, then it was delayed. More recently, Mazda told us it'd first land in the CX-5 – and in fact, there's a part of the Mazda USA website devoted to the diesel crossover, which makes it seem more legitimate than previous pronouncements. But the fact of the matter is, there's some unforeseen hiccup in the government approval process for this engine, likely centered around emissions standards, and it seems to be dragging on. But this Mazda6 was spotted at an EPA facility in Michigan, which gives us some hope that perhaps the company is rounding the final base on the approval process. It looks very much like an American-spec Mazda6 to our eyes ... except for the strange, possibly temporary exhaust outlets, which might be required for EPA testing. The rear looks like a current-look car, rather than the revised 2018 styling that will get the 2.5-liter turbocharged gas engine. Since the Mazda6 was originally supposed to get the Skyactiv-D engine, we can only assume that if it's at an EPA facility, Mazda is hoping to bring it to market here – likely sometime after the CX-5 goes on sale. If Mazda can get approval, it'll be another point of differentiation between the Mazda6 and its competitors – there's no currently-approved diesel sedan that's a direct match. The smaller Cruze and larger, more expensive offerings from BMW and Jaguar are about it. The fuel economy guide (PDF) produced by the EPA back in late 2017 lists both the CX-5 and the Mazda6 as having diesel engines, but neither are rated, and as we know at this point, neither are on sale or have an official timeline for doing so. We can assume anything with an application in progress made it on the list, whether approval would be granted or not. It seems unlikely at this point that Mazda would abandon the Skyactiv-D in America. It's a solid part of their strategy, although a product roadmap released a few months ago shows that Mazda expects diesel sales globally to taper off after 2020, to be supplanted by plug-in gas hybrid, EV, and fuel cell vehicles. But between now and about 2030, pure diesel cars are expected to be a small but significant portion of Mazda's product mix. We hope this means we'll see the CX-5 emerge from the approval process and hit dealer lots soon, to be followed by the 6.

Mazda2 with extended-range hybrid rotary tech shown

Every story dealing with a new rotary engine from Mazda lands in a different place on the matrix of possibilities between "Coming soon!" and "Never gonna happen!" In 2011 it was speculated that the rotary engineering program would be shut down with the demise of the RX-8, in 2012 the program was still alive and taking lessons from the SkyActiv engines, in August 2013 a Mazda insider said a rotary engine called 16X would be here in two years, in November the CEO said the only way we'd ever get a new rotary is if Mazda could sell 100,000 of them per year. Meaning that, for the moment, you can forget about it.
And yet, last month Mazda was putting journalists in a Mazda2 RE Range Extender, an electric car using a 0.33-liter rotary to power its lithium-ion batteries when the charge runs down. With a 75-kilowatt, 100-horsepower electric motor turning the front wheels, the Wankel generator and its 2.6-gallon gas tank living under the trunk double the range of the electric-only Mazda2 to 250 miles.
There's been talk of using a rotary to assist an alt-fuel vehicle for at least seven years, with Mazda pairing an electric motor with a rotary that ran on gas and hydrogen in a Mazda5 in 2007. Since then, almost all of those stories debating its return or demise also spoke of the oddball motor's advantages, such as compact size and ability to run on various fuels, as an aid in an unconventional powertrain.

R&T chases down a burglar in the million-mile Miata

Is the answer always Mazda Miata? We discussed this in passing on the Autoblog Podcast earlier this week, and most assuredly the answer is "no." For example, the little MX-5 would be a terrible people carrier, and it'd be useless off road. You can't really tow anything of substance with it, either. Still, if push came to shove, it's satisfying to know that the diminutive roadster could eke out a career as a chase vehicle for the police.
That fact was proven when Road & Track editor Chris Cantle did something that he himself recognizes as "stupid." Upon returning home, Cantle discovered a "twenty-something" actively burgling his home. The resulting story is easily one of the more entertaining episodes to come out of the 1990 MX-5's service to the team at R&T and, we're guessing, will be one of the highlights of the Million-Mile Miata challenge.
Be sure to head over to Road & Track for a full retelling of the chase from Cantle, as well as a follow-up on the saga.
