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.

2016 Mazda CX-5 [w/video]

It's difficult for me to get excited about crossovers. I try hard not to be the stereotypical car guy: ignoring the fact that the rest of the world loves these tall hatchbacks, while yelling, "station wagons make more sense!" until I've voided my lungs of air. Deep down I am that guy, but I work around it. Historically the Mazda CX-5 is one crossover that has been quasi-immune to my knee-jerking. It doesn't weigh two tons, offers a manual transmission (in poverty spec, but still...), and looks faster than its competitors. Most importantly, the CX-5 can round a corner without wobbling like a Slinky at the top of the stairs. No item on that list of plaudits would likely crack the top ten "desirables" for average small CUV shoppers. So, for the 2016 update, Mazda instead upgraded the in-cabin experience along with the requisite nips and tucks to the exterior. I borrowed a 2016 model CX-5 to see whether or not those concessions to comfort affected the car-nerd stuff. And to see if the Mazda could still be my go-to CUV recommendation. Driving Notes The engine options are unchanged for 2016. You can still have the fine, 2.5-liter four-cylinder engine, with its 184 horsepower and 185 pound-feet of torque, or its wimpier 2.0-liter lil' brother. My fully spec'd Grand Touring came with the bigger engine, which feels adequately powerful for the class, but not quick. In an era where turbocharged engines are everywhere, revving the Skyactiv 2.5-liter up to its torque peak at 3,250 rpm takes some commitment. I'm annoyed that there's no manual offered with the 2.5L (a combo I can have in both the Mazda3 and Mazda6), but I don't hate the automatic transmission. The six-speed unit is unobtrusive 99 percent of the time; something I regretfully can't tell you about certain nine-speed autos. There are no paddles to play with, but you can tap the shift lever up and down if you're struck by a need for total control. With a new center console and dash, and the addition of the Mazda Connect infotainment system, the '16 CX-5 feels like a new vehicle from behind the wheel. An attractive, pliant, leatherish material swaths the neat console and surrounding real estate. And the perforated leather seats feel damn near upscale. I think that Mazda Connect's version of the central control knob (with handy adjacent volume knob) is almost luddite-proof in its simplicity. There's no latency between twisting and reaction on the screen.

Mazda3, CX-5 earn IIHS Top Safety Picks

Mazda technologies like SkyActiv-Body and SkyActiv-Chassis, plus ultra-high-tensile steel, six airbags, "crusable" brake and accelerator pedal assembly and collapsible steering column have helped the 2013 Mazda3 and 2014 Mazda CX-5 win Top Safety Pick laurels from the Insurance Institute for Highway Safety (IIHS). It's the second year in a row for the Mazda3.
The accolade is earned by receiving "Good" marks for frontal moderate overlap crashes, side and rear impact crashes, and tests of roof strength. Remember, the small overlap test that the IIHS commenced in August 2012 has lately tripped up some makers who have excellent safety reputations.
The Mazda3 and CX-5 join offerings like the Dodge Dart, Hyundai Elantra, Mitsubishi Outlander Sport and Subaru Forester among the 117 vehicles so far declared Top Safety Picks - which is different than the 13 named Top Safety Picks+, mind you - for this year.
