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.

Mazda CX-30 'just right' crossover will head from Geneva into production

As more and more customers move into the crossover segment, the less the segment is one-size-fits-all, or even three-sizes-fit-all. As such, Mazda has taken the opportunity at the Geneva Motor Show to offer a new, "just right" crossover to its lineup. The 2019 Mazda CX-30, as it's called, slots between the diminutive CX-3 and the compact CX-5 crossovers. The CX-30 shares the "Kodo" (meaning "soul of motion") design language Mazda does so well, and the execution here is excellent, too. We love the long hood and simple but elegant curves, the way the light reflects off the sides in dramatic waves. Its no surprise that Mazda chose its Soul Red Crystal to show off the new model. Mazda says it had four goals for the CX-30, two of which had to do with the size of the vehicle. It needed to be small enough to be highly maneuverable, so that drivers wouldn't hesitate to take it anywhere they need to go, but it also had to be roomy enough to provide a comfortable space for multiple passengers to easily enjoy one another's company. Mazda wanted the design to "embody the joy of owning something that matches your sensibilities." Finally, it had to perform in a way to provide peace of mind and a relaxing driving experience. Mazda will offer the CX-30 with its Skyactiv-G 2.0 gasoline engine with cylinder deactivation, Skyactiv-D 1.8 diesel engine and its new Skyactiv-X engine with gasoline compression ignition. Both gasoline engines will use Mazda's mild hybrid technology to help improve fuel economy without sacrificing performance. The CX-30 will also be offered with Mazda's I-Activ all-wheel drive and G-Vectoring Control Plus for maximum grip and stability. It will be available with either a six-speed manual or six-speed automatic transmission. The CX-30 is equipped with a driver monitoring system to improve safety using an infrared LED and camera to watch the driver's face for signs of drowsiness or inattentiveness. It'll alert the driver to pay attention, and will sound the braking alert earlier. Other active safety systems include available Front Cross Traffic Alert and Cruising & Traffic Support, the latter of which will employ accelerator, brake pedal and steering operations in traffic jams to help avert driver fatigue. Mazda hasn't said whether it will offer the CX-30 outside of the European market. Related Video:

Mazda keeping non-hybrid, non-electric Skyactiv strategy

Mazda still thinks that it can buck the trend of adding those fancy batteries and electric motors to its cars. At least for a little while longer. Hopefully. Speaking to Auto Express recently, Mazda's European boss, Jeff Guyton, said that he expects his company's cars to be able to get a lot more efficient without resorting to any of that fancy electrification stuff. "I think there's at least 20-30 percent better fuel economy by the end of the decade," he said. He said that he expected to get to Europe's low target of 95 grams of CO2 per kilometer, "without any significant deployment of electrical drive." This part is all in line with Mazda's long-term Skyactiv strategy, as laid out back in 2011 and first mentioned publicly in 2010. Remember, this is the company that once proudly proclaimed, "Not Electric. Not Hybrid. Not A Drag To Drive." As explained back in 2011, Mazda hopes to wait until other automakers have done all of the heavy lifting on developing plug-in and hybrid tech so that when Mazda enters the market, things will be cheaper. Of course, Mazda has been quietly testing all-electric vehicles and Guyton said that there may be an Mazda EV at some point. "We are interested in electric technology and it will be in the distant future when it will be quite important," he told AE. "But we think it will take some time to be commercially attractive without tax payer-funded incentives." How much of a delay? Well, there is a gas-electric Mazda 3 hybrid available in Japan that uses some powertrain parts from the Toyota Prius, and we all know that the Prius has been around for ages. Maybe in 2025, Mazda will come out with a Leaf-based Mazda 2. Related Video: Green Mazda Fuel Efficiency Electric Hybrid skyactiv mazda skyactiv
