Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

Premium design and diesels: Mazda may be the next VW

At the Chicago Auto Show, we had a chance to sit down with Jacob Brown, a Mazda PR representative, and Jacques Flynn, a lead exterior designer at the company, to talk about design and where the company is going. One of the themes of our discussion was the company's desire to move its lineup toward a more premium, upscale feel and image – both in terms of vehicle design and powertrains. We realized the company may be looking to take a page from Volkswagen's American playbook, positioning itself as a prime purveyor of affordable, upscale – and most importantly, fun to drive – automobiles. In the case of design, Flynn talked about how Mazda's KODO design language is going to evolve; that the goal is to simplify and refine the look. We discussed the CX-5 as an example of this evolution. Flynn pointed out that the goal was to add more refinement and simplicity, and showed how Mazda achieved this on the CX-5 by straightening the curves from the previous model to give it more visual length and a more taut shape. The grille also was given more depth and detailing, which isn't simplified per se, but does provide a more premium look. View 9 Photos Mazda's upcoming diesel engines are another piece to Mazda's premium puzzle. The company will finally offer a diesel on the CX-5. While Mazda planned not to use urea-injection, it finally resorted to the system so the engine could both meet performance benchmarks and emissions standards. In addition to the efficiency of the engine, Brown said that diesel engines have a premium nature for buyers. This is due in part to the luxury automakers that mainly offer them in the US, such as BMW and Mercedes-Benz, and to the fact that the technology will add some cost to the product. If all of this sounds familiar, it's because you know these characteristics used to describe Volkswagen: a company known for upscale, affordable cars, providing great driving dynamics – and formerly, for efficient and fun-to-drive TDI diesel engines. While we didn't touch on the driving experience of modern Mazdas in our interview, you can simply look at any of our reviews to see that we generally like what the company builds. The only downside is that we may have to wait a while for some models, and others may never show up here. Brown and Flynn both said that the Mazda2 is unlikely to be offered in the US as anything other than the Toyota Yaris iA, since it's hard to convince people that a subcompact is premium. No surprise there.

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.
