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.

Perk up your Mazda Miata with BBR's new 248-horsepower turbo kit

For three decades, enthusiasts have argued whether the Mazda MX-5 Miata needs more power. For its part, Mazda seems fine with leaving the Miata as is, even reducing the horsepower from the third- to fourth-generation models, though the car lost a little weight. That's where tuners like BBR in the UK and Flyin' Miata here in the US step in, offering aftermarket solutions for those that crave a little more grunt. BBR announced today that its new 248-horsepower Stage 1 turbo kit is ready and waiting for the new 2.0-liter-powered ND Miatas, including the new Miata RF. BBR's first Miata turbo kit was released all the way back in 1990. Since then, the shop has been tuning and honing its craft, releasing ever-more potent variations its comprehensive power kit. This new version, like the previous ones, focuses not only on adding more power but maintaining the level of drivability and refinement you expect from all Miatas. The Mazda electronic safety features are retained, and the team is working on CARB emissions approval. That said, with BBR tune an ND Miata will hit 60 mph in just 5.0 seconds, roughly two seconds quicker than stock. To get the peak 248 horsepower and 236 lb-ft of torque, BBR does more than simply slap on a big turbo. In 2014, BBR began using a Mazda3 as a development vehicle in preparation for the new Miata's launch. A twin-scroll turbocharger is mounted onto a custom cast-iron manifold. A front-mounted aluminum intercooler keep things cool and doesn't require cutting up the bodywork. The engine breathes in through a K&N air filter and exhales through a stainless steel downpipe. The whole thing is controlled by BBR's Starchip / EcuTek RaceRom ECU software package. Other upgrades include silicone turbo pipes, an aluminum battery tray, a recirculating piston type dump valve, a carbon-fiber heat shield, and stainless steel oil and water lines. BBR is offering extended warranties from 12 to 36 months. In the US, the sole distributor is Flyin' Miata in Colorado. At $5,695, it's not a cheap proposition, but it is less expensive than one of Flyin' Miata's V8 swap kits. Less expensive (and less potent) performance kits are also available.

Recharge Wrap-up: Mazda, Subaru and Toyota PHEV, Nomadic Power grant

The next generation of the Toyota Prius Plug-in Hybrid looks to be important for Mazda and Subaru as well. Toyota will likely need to sell more of the new plug-in hybrid to meet stricter ZEV standards in California. That means it will get more extra electric range, as customers have been asking for. Subaru and Mazda will also have to adhere to the California standards beginning in 2018. Those two smaller automakers will likely license a plug-in hybrid powertrain from Toyota in order to fulfill compliance. Read more at Green Car Reports. Tesla is partnering with Dalhousie University to improve battery technology. Tesla signed a five-year research agreement with Dalhousie's Jeff Dahn, a lithium-ion battery researcher. Dahn and the 25 researchers in his lab will work with Tesla's Director of Battery Technology, Kurt Kelty, to increase capacity through improved materials. The collaboration could be important both for Tesla's automotive and stationary batteries. "Our research group's goal is to increase the energy density and lifetime of Li-ion batteries, so we can drive down costs in automotive and grid energy storage applications," says Dahn.

Nomadic Power's mobile batteries, called Nomads, have incorporated photovoltaic systems and can be used to extend the electric driving range of a plug-in vehicle, or to provide backup power to a home. The Nomads use an intelligent energy management system to learn and predict user behavior and manage the solar system based on weather forecasts. "We see a strong future in electric-powered mobility and an increasing use of renewable energy, photovoltaic power in particular," says Nomadic Power CEO Dr. Manfred Baumgaertner. "Our mobile batteries have great potential in these markets that recently got a significant shot in the arm by Tesla's announcements." Read more from Nomadic Power, and at Green Car Congress.
