The spirit of these 7 weird Mazdas lives on in today's cars

HIROSHIMA, Japan — When visiting the Mazda Museum in Hiroshima, housed amidst the company's main manufacturing site on the shore of the Enko River, you can follow Jujiro Matsuda's early 20th century entrepreneurial path from artificial cork manufacturer to machine and machine toolmaker, to motor vehicle producer. But probe a bit deeper into the exhibits, and you can uncover more than just a chronicle of corporate achievements: delightfully weird outliers, paragons of oddball design, engineering and marketing solutions It's looking at these delightful misfits that really illustrates Mazda's tale. You can also see precisely how many of these vintage conveyances led directly (or indirectly, or obtusely) to Mazda's most iconic American-market cars and trucks. Our seven favorite precursors, and their lovable successors, are listed below. 1931 Type TCS/Mazda B-Series Mazda's first vehicle was this little three-wheeler, powered by an air-cooled, one-cylinder motor. Because the company lacked a distribution network at the time, the trucklet was marketed by Mitsubishi; hence the three-diamond pattern on its side. All of this is very reminiscent of the company's eventual foray into the U.S. market, where its sales were spearheaded by compact pickups. The B-Series, which was one of the first Mazda vehicles available in the U.S., arrived in 1972, and stuck around through the first decade of the 21st century. Like its partnership with Mitsubishi, Mazda teamed up with stakeholder Ford to market this little truck as Ford's first small pickup, the Courier, the precursor to the Ranger. There was even a rotary-powered B-Series for a few years, but we're getting ahead of ourselves. 1968 Bongo Van/Mazda5 The Bongo allegedly was the first one-box van design in Japan, and apparently it was so popular that the name Bongo became, for a period of time, the generic metonym for the category—the way that Kleenex is a stand-in for all facial tissue. With a tiny rear-mounted engine and a planar expanse of metal to push around, it was not particularly fast, but it was both spacious and innovative. The same could be said of the brand's mini-minivan, the Mazda5, which was available for a couple of generations in the States in the Aughties. Sadly, the name 5 never caught on as a synonym for fun-to-drive family hauler, at least not yet, and the category itself (like nearly every other car category) was crushed in America by the rise of the crossover.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

What a 181-horsepower 2019 Mazda MX-5 Miata means for us, and you

Last month, we reported on a VIN filing dug up by Road & Track that showed that the 2019 Mazda MX-5 Miata's 2.0-liter Skyactiv-G engine would get a power bump, from 155 to 181 net horsepower. As for how the 2019 Miata would make that extra power, we heard rumors it'd utilize a new cylinder head allowing higher revs, accounting for that extra power. Now we have what appears to be a leaked document from Mazda Canada showing exactly where that extra power comes from. According to the document posted at Miata.net (registration required to see the image), Mazda will alter camshaft lift and valve size on both the intake and exhaust side, fit freer-flowing exhaust, and smooth and enlarge the piping on the air intake side. There are also internal engine modifications: lighter pistons with lower crowns for better swirl in the combustion chamber, lighter connecting rods, and a crankshaft balanced for higher-RPM operation. All those extra revs mean extra vibration and noise, so Mazda will ditch the single-mass flywheel for a "low-inertia" dual-mass flywheel – which will attempt to find a nice balance between DMF damping action and SMF directness. Overall, it's a pretty serious engine revision with some driveline changes that will heavily affect the driving characteristics of a fantastic driver's car. Contributing Editor James Riswick and Senior Editor Alex Kierstein, both well versed in Miatas past and present, are here to analyze what this could mean for the little roadster. James Riswick: I don't know much about them lighter crank combustion rods, but I for one welcome the news of more power to the Miata. The jump from 155 to 181 seems like a very prudent Mazda-like thing to do, accomplishing that task through various aforementioned technical wizardry as opposed to slapping on a turbocharger, exclaiming "yee-hah" and calling it a day. Alex Kierstein: That's true. I'm wary of additional power, but you do make a good point that at least this is the right way to do it. Going all-motor will keep the bright responsiveness of the engine intact. But higher revs might make power delivery peakier. Frankly, I'd be ok with moving the torque and horsepower peaks up a bit in the rev range, making it a bit more work to access the engine's sweet spot. The dual-mass flywheel should also help if low-end torque suffers, so less stalling in traffic. JR: Did wonders in the 911 and 718s.
