Road & Track to take Miata on million-mile march

Road & Track has taken on a Miata project. One hell of a project, if we're honest. You see, the Miata in question, a 1989 example in Mariner Blue, isn't a high-mileage Mazda that the publication intends to fix up, or make race-worthy, or try to flip or give away to a reader or something. No, it's a rather typical well-used NA, with a hefty 325,000 miles on the clock to-date that the staff plans on driving until the six-digit odo reads all zeros again. One million miles or bust (or both, most likely).
Procured for the bargain-basement price of $1,600, complete with seat covers that "really do look like muppet pelts" (according to Zach Bowman) and a bondo-filled love tap on the nose, the NA Miata actually looks like just the sort of fun-machine that a real driving enthusiast would pick up to get some cheap thrills in. The R&T team already has some interesting plans for the Miata, including a potential run up Pikes Peak and loaning it out to readers (or perhaps your author...). Click through to read all about it.

Remember that diesel Mazda has been promising? It's coming in the CX-5

Mazda has been talking about bringing a diesel to the US since the current Mazda 6 debuted. It's been delayed, delayed some more, and then seemingly forgotten, but now comes word that the diesel four-cylinder will arrive here in the second half of 2017. It's just coming in the CX-5 first, not the 6 sedan. The diesel in question is Mazda's Skyactiv-D 2.2-liter four, which makes 173 horsepower and 310 pound-feet of torque in other models. Putting it in a small crossover makes some sense, especially considering the recent announcement of a diesel Chevy Equinox. It's good news for choice and another sign that the diesel scandal brewhaha's effect on diesel decisions is blowing over. If it works in the CX-5, we may see this option spread throughout the Mazda lineup. Now if only someone could make a case for that rotary...

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.
