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 MX-5 Miata shows off perfect 50/50 weight balance

When I attended the first drive event for the Japanese-spec 2016 Mazda MX-5 Miata in Spain earlier this year, I was blown away – and not just by the car. I was blown away by the charts and graphs Mazda's engineers brought along, showing how every little facet of the ND Miata was finely tuned for pure driving perfection. It's like rocket science. Only cooler. One of the most important parts of the Miata package is its weight distribution. The 2,332-pound roadster must achieve a perfect 50/50 balance, with a driver inside. That's not easy. But it has to be done. Only the best for the Miata. In this video, Mazda shows off the Miata's balance by putting it on an aluminum balance beam, to see if the car stays perfectly centered. You can probably guess the outcome, but watching it all take place is super cool, especially with commentary by Mazda engineer Dave Coleman and MX-5 program manager Rod McLaughlin. How does the 50/50 balance help the Miata's handling out on the road? You'll have to wait until the embargo on driving impressions for the US-spec car lifts. We'll have the full scoop at 3:01 AM Eastern on Monday, June 1. In the meantime, get a sneak preview of the new Miata in the video below. Autoblog readers got a closer look at the 2016 MX-5 at our Cars & Coneys meet-up, and as you can see, the excitement for this car is definitely real.

2015 will be the biggest year ever for cars at CES

Like the SEMA Show, major automakers are paying increasing attention to the CES, with 2015 expected to be one of the most auto focused yet. Ford, Volkswagen, Toyota, General Motors, Hyundai, Mazda, Audi, BMW and Fiat Chrysler Automobiles will all be in attendance when CES 2015 kicks off next week, taking up a record-breaking 165,000 square feet of space at the Las Vegas Convention Center. "We've come a long way from a single car on a carpet," Ford's Alan Hall told Bloomberg. Unlike SEMA, or a more traditional auto show, like the upcoming festivities in Detroit, CES doesn't necessarily focus on entire cars or the way they perform, but on the way our technology will interact with vehicles, and in how those vehicles will deliver information to drivers. "CES has become a major launch point for a lot of the big automakers," IHS tech analyst Mark Boyadjis told Bloomberg. "CES is a way for them to get on a global stage for technology." As for what kind of wares automakers will trot out in Las Vegas, we already know that BMW will show off an autonomous i3 electric car that can navigate its way through a multistory car park and can be hailed via a smartwatch app. According to Bloomberg, Hyundai will show off its own smartwatch app for the Genesis sedan, while Audi and Mercedes-Benz will show off autonomous vehicles next week. Automakers won't be the only companies looking to capitalize on CES. Tech firms, like chipmaker Nvidia, are becoming increasingly involved in the automotive game and will be in town showing their wares off to OEMs. "Two years ago, our booth would have been filled with PCs and people playing video games," Danny Shapiro, Nvidia's senior director for automotive business, told Bloomberg. "This year we made a strategic decision to shift the focus of the booth on automotive and de-prioritize some of the other things." Needless to say, you can expect to see a lot of news out of Las Vegas come next week. Stay tuned.
