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.

Junkyard Gem: 1982 Mazda RX-7 GSL

The early Mazda RX-7 was one of the few bright spots for sports-car shoppers during the Malaise Era, a lightweight and simple rear-wheel-drive machine with a screaming Wankel engine under the hood. Even though it was designed mostly as a means of getting Japanese car buyers a loophole to keep their engine-displacement-based road taxes low, the early RX-7 sold well in North America. I still find these cars during my junkyard travels, but the 1981-1983 FB-series RX-7s have been getting scarce in recent years. Here's a very solid '82 that showed up in Denver during the winter. Japanese cars of this era tended to rust early and often, but this one appears to be absolutely corrosion-free. The odometer shows just a hair over 100,000 miles, so I'm guessing this car spent decades in covered storage. The seat leather shows a few rips, but the interior looks pretty good overall. The body has some dents and dings, nothing serious. It wouldn't have taken much to get this car back on the road and looking good. The GSL package got you four-wheel disc brakes, a limited-slip differential, and these cool-looking pillar badges.  The list price on a new 1982 Mazda RX-7 GSL came to $11,895, or about $32,350 in 2020 bucks. A new Datsun 280ZX coupe went for $14,499 that year, but was a much more powerful and prestigious car; the less opulent 200SX was just $7,739. If you wanted a new Celica Supra, the price tag was $14,598. The final year for the Fiat-badged 124 Spider (they were sold with Pininfarina badging for a few additional years) was 1982, and that car cost $12,290. Meanwhile, your Chevrolet dealer had new Z28 Camaros starting at $9,700 that year; the RX-7 would eat up the Camaro on a tight road course but would be blown away on the straights. The 12A rotary engine in this car made 100 horsepower from just 1.1 liters of displacement, putting smiles on the faces of those Japanese road-tax payers. Unfortunately, fuel consumption was scary, particularly in the immediate aftermath of the 1979 Oil Crisis. Why did this car end up in a place like this? It was found in an office parking lot with a flat tire and expired registration tags and towed away. Then it failed to attract any bidder interest at the subsequent auction and U-Pull-&-Pay picked it up for next to nothing. So, if you ever wanted an early RX-7, buy the next cheap one you find before it meets a fate similar to that of today's Junkyard Gem. This content is hosted by a third party.

2016 Mazda MX-5 Miata design walkaround

By now, you've likely read what we think of the 2016 Mazda MX-5 Miata's new looks both inside and out, and you've probably poured over the available photos and started to make up your own mind about the roadster's radically more aggressive new appearance. More than likely, however, you haven't heard much from Mazda itself about its new design, and we're here to remedy that. Join Autoblog as we go over the new Miata from tip to tail with Derek Jenkins, Mazda North America's director of design. Jenkins, a veteran of both Audi and Volkswagen design studios, has been with the Japanese automaker for nearly four years, and he's kept a close eye in the ND Miata program along with his team in Irvine, CA. Check out our video to see Jenkins explain his team's exterior and cabin handiwork and to learn a little more about why the new model graduates from the Miata's historically cute and friendly aesthetic to something altogether more assertive.
