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.

Junkyard Gem: 1990 Mazda 929 S

In the late 1980s, Toyota, Nissan, and Honda were cleaning up in the American market with the Cressida, Maxima, and Legend, respectively. Mazda wanted some of those dollars, so the HC-series Mazda Luce was modified for the US market and sold here as the 929. It had rear-wheel drive, a powerful V6 engine, and lots of luxury features, but not many were sold. Here's a rare '90 that I spotted in a San Francisco Bay Area self-service yard. In 1990, the sporty 929S version got 190 horsepower from its DOHC 3.0-liter V6. Unfortunately for Mazda, American buyers associated the marque with sensible econoboxes and screaming rotary engines, not luxury machinery, at the time. For the 1990 model year, American-market cars were required to have either a driver's-side airbag or automatic seat belts. The 929 had the automatic belts, the less said about the better. The Luce-based 929 became the Sentia-based 929 for the 1992 model year. Meanwhile, the new luxury brands from Honda, Nissan, and Toyota were kicking the crap out of 929 sales; Mazda had planned to launch the Amati brand in the United States, but didn't have the resources to follow through. The last 929s were sold in the United States for the 1995 model year. Related Video: Featured Gallery Junked 1990 Mazda 929 S View 16 Photos Auto News Mazda

Mazda on sales upswing in Europe but won't build there

Auto sales in Europe have been a tricky proposition for some years, but Mazda has seen some success on the backs of the CX-5 and new Mazda6. According to a report form Automotive News Europe, though, that doesn't mean we should be looking for the Japanese manufacturer to set up production operations there.
Mazda's European CEO, Jeff Guyton, explained to AN that "Our intention is to have manufacturing scale. That gives you scale economy and quality through repeatability." In other words, a big honking plant in one part of the world is preferable to a half dozen small factories building the same vehicles.
European sales for Mazda are up 5.4 percent in the first half of 2013, with 74,000 units sold. That kicked the Zoom-Zoom brand's market share up from one to 1.2 percent. Small gains, but gains nonetheless. According to Guyton, Mazda would need to sell 200,000 units of just one model in Europe for local production to make sense. Mazda's best European year saw 320,000 units sold across the entire range.
