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 explains the thinking behind the MX-30's small battery pack

Mazda's first production-bound electric car, the MX-30, relies on a 35.5-kilowatt-hour lithium-ion battery pack for power. That's relatively small, but the Japanese firm argued it's exactly what the model needs to let motorists drive electric while keeping their environmental footprint in check. Christian Schultze, head of Mazda's European research and development center, told Automotive News Europe the MX-30's battery is responsibly-sized. He explained engineers took a variety of factors into account when debating kilowatt-hours, including how much energy is required to build the pack, how much electricity is needed for a full charge, and the environmental impact of replacing the battery, which Mazda expects could be necessary after the MX-30 has covered about 100,000 miles. Sticking with a smaller pack yields total CO2 emissions on par with a turbodiesel-powered Mazda3. In contrast, using a 95-kilowatt-hour battery (which is close to what Tesla's bigger models use) would have increased the MX-30's life-long CO2 output considerably by requiring more energy to build, and needing far more electricity to achieve a 100% charge. We're not quite sure that math or battery longevity assumption hold up under scrutiny. In any case, small is the direction Mazda decided to go. The trade-off is that the MX-30 (pictured) is expected to drive for about 124 miles between charges, and that figure was achieved on the hugely optimistic WLTP testing cycle; real-world mileage will be lower. That's hardly a jaw-dropping number, and the crossover doesn't qualify for the coveted long-range label, but Schultze told British magazine Autocar it's more than enough to cover the daily transportation requirements of the average European motorist, which stands at a total of 31 miles. That's significant, because Europe will be one of the MX-30's key markets. Deliveries are scheduled to begin in early 2021. Mazda hasn't announced whether it will sell the MX-30 in the United States, or if it will wait until it has a longer-range electric car to enter the segment.

'Gran Turismo Sport' Super Bundle comes with a real Mazda Miata

"Gran Turismo Sport" is now on sale (stay tuned for a full review in the near future), and as with most video games now, there are basic versions and those that come with a few extras. For instance, in the United States there's a Limited Edition version that includes the full game, plus a metal box, several Group B rally cars and a couple of prototype cars unlocked, as well as 1,000,000 credits available at the start. It's a pretty meager special edition compared with the "Gran Turismo Sport" Super Bundle on offer in Taiwan, though. The Super Bundle lives up to its name primarily because it comes with a real, drivable Mazda MX-5 Miata. It comes in Soul Red and features custom Gran Turismo vinyl graphics. On top of that, the bundle comes with a Bravia 4K HDR OLED TV, a Playstation 4 Pro, Playstation VR, a year of Playstation Plus (the online multiplayer service), a Thrustmaster T-GT steering wheel controller, and an Apiga AP1 racing seat for playing the game. Oh, and of course it comes with a copy of the game. Funny enough, this isn't the first time a car has been offered as part of a video game bundle. When " Grid 2" launched a few years ago, the developer, Codemasters, partnered with BAC to sell a Mono edition. This special edition of the game came with a real life BAC Mono with "Grid 2" livery. There's no such thing as a free lunch, or a free car for that matter. At current exchange rates, the " Gran Turismo Sport" Super Bundle costs just shy of $46,300. Now that's a much more affordable proposition than the " Grid 2" BAC Mono package, which rang in at about $189,000, though the Miata is a much more affordable car with less performance. Americans shouldn't be disappointed the " Gran Turismo Sport" Super Bundle isn't available here, though. This is because the Super Bundle can be re-created here for much less money. Every item in the bundle plus a Miata Sport with a manual transmission and the Soul Red paint would come to a little under $32,000, a savings of over $14,000.
