10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

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.

2020 Mazda3 hatchback starts at $24,620, a $100 increase

Car and Driver got the scoop on some 2020 Mazda3 pricing, and anyone waiting for the new model year had better bring more money. The Mazda3 sedan goes up by $500 to $21,500. After the $920 destination charge, that's a total of $22,420. On the sedan, however, the extra dosh pays for extra equipment. Every sedan trim gets Mazda's i-Activsense driver assistance tech, meaning adaptive cruise control, automatic emergency braking, blind-spot monitoring, lane-keep assist, and lane-departure warning. The i-Activsense suite had been an option the sedan's entry-level trims. The Mazda3 sedan in Select guise, one step above the entry-level model, increases $100 to $23,620. Starting price for the front-wheel drive 2020-model-year hatchback comes in at $24,620 after destination. C/D says that's a $1,020 bump, but we believe that figure is an error. Based on the fact that Mazda's U.S. pricing rounds off to the nearest hundred and destination is $920, it seems more likely the $24,620 price includes destination. In that case, the 2020 Mazda3 hatch only goes up by $100. The five-door models don't get any more equipment, but Mazda say's there's a new finish for the wheels on the top-tier Premium trim. All other trims hold steady. The 2.5-liter four-cylinder with a square 186 horsepower and 186 pound-feet of torque remains the sole engine option, a six-speed automatic is the standard transmission on all trims, the hatchback in Premium form offering a six-speed manual option. Buyers of the entry-level sedan are stuck with front-wheel drive, while every other trim offers all-wheel drive for $1,400. The sedans should hit dealerships this month, and the hatchbacks will roll in come September.
