2019 Mazda CX-5 Signature AWD diesel unveiled in New York

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.

Why Mazda’s Skyactiv-X compression-ignition engine is a smart hedge bet

Mazda has cracked the code on a compression-ignition engine, called Skyactiv-X (which utilizes SCCI, or Spark Controlled Compression Ignition). That's a neat engineering accomplishment, sure, but why is the tiny company investing big dollars in fancy tech that's frustrated the much larger companies who've investigated it? In this case, Mazda is peering into a crystal ball to consider how best to flow with a few troubling tides. One is the premature handwringing about the death of the internal combustion engine, another is Europe's swing away from diesel engines. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum infrastructure — no shock there. Mazda claims the tech will net 20-30 percent gains in fuel efficiency over its current gasoline engines and about matching its diesel engine. And that's without any onboard hybrid tech, so that staves off the inevitable necessity to fully adopt electrification for a while — this is assuming that, at some point, it won't be practical to sell a non-hybrid or non-EV. At what date that happens is open to debate, but as I said above, technology like this kicks that decision point down the road a bit. Mazda is here translating research dollars into time, allowing its engine factories a few more years of probably profitable production of internal-combustion engines before retooling, and before somebody needs to pour a massive amount of money into a broad EV charging infrastructure to replace gas stations. None of this is happening fast enough for a wholesale transition to EVs anytime soon. So, that's one bet hedged. The next is Europe's declining interest in diesel engines for mainly health reasons. Just about a week ago, The New York Times posted an excellent primer on this issue, which is somewhat controversial in Europe. Germany's auto industry, a huge portion of its economy, is heavily invested in diesel tech and seriously opposed to proposals in Britain and France to eliminate the technology, which creates unhealthy diesel particulate emissions. The German industry is hoping Band-Aids like pollution-reducing measures will help them, but after a massive and widespread emission cheating scandal, its credibility is at a nadir. It seems like consumers have sensed which way the wind is blowing, and it has hurt sales. The NYT reports that diesel sales in Germany alone — remember, bastion and originator of diesel technology — are down 13 percent.

Cedar Rocket is the fastest all-electric log car in the world

An electric turbine manufacturer, a mechanic, and a log house builder walk into a bar. No, wait. The three are standing around at Barrett-Jackson a few years ago, talking about the world. What's the eventual punchline? An all-electric vehicle mash-up of a Mazda RX-8 and a giant piece of wood. One that was just awarded a Guinness World Record for "fastest motorized log." "Truly, what else would you think of?" - Bryan Reid, Sr. Bryan Reid, Sr., star of the reality show Timber Kings, is the log house builder in the set-up above, and he's now the proud owner of Cedar Rocket. He told AutoblogGreen that a log-based EV is the natural result of the three guys chatting. "Truly, what else would you think of?" he said. "I mean, really? There has to be something to come out of it other than girls. It was crazy, but it's a good story and nobody gets hurt. It's hard to make the news when everything's positive." Idea in hand, Reid and his friend set off to actually build the car. Gerald Overton, the mechanic, turned the Mazda into a welcoming recipient, working on the disc brakes, axles, frame, differential, and suspension. While the presence of a television producer kept things moving, Reid said that it still took almost two years. "It started out, not as a joke, but as something very light," he said. "You put a log on a couple of axles and 'ha ha.' It ended up taking many thousands of hours. We don't do anything halfway." In the end, Reid and the team took the Cedar Rocket to the Wild Horse Pass Motorsports Park in Chandler, Arizona and managed two runs of 55 miles per hour within an hour (that's what Guinness required to hand out the official record). The Rocket is incredibly stable – heavy batteries help there – and Reid pointed out that because the EV uses electric turbines, it's not a quarter-mile car. "It's more like a salt-flat car," he said, because the "turbines that take a while to spin up." Given the right conditions, Reid said the team thinks the Cedar Rocket could go 120-130 mph. "It's crazy because it's different." But the point of this car isn't to just go fast. The builders will bring the car to Barrett-Jackson and auction it off next year, but before that it will make the rounds at places like SEMA and a number of unexpected events, like golf shows. The point is to get attention and raise money and awareness for veterans groups. "I believe it's for the best cause in North America," he said.
