Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

2014 Mercedes SL and SLK add small expansion to Takata airbag recall

Mercedes-Benz is the latest automaker to be affected by Takata's massive airbag recall. The company has announced a voluntary recall campaign on a small number of model-year 2014 SLK- and SL-Class roadsters.
In Mercedes' case, 300 vehicles are affected, 200 of which are in the hands of customers. According to spokesperson Donna Boland, the affected roadsters were built between March and April of this year.
The issue, which is apparently the fault of one of Takata's subcontractors, rests with some improperly installed fasteners, which could keep the airbag from performing the way it's supposed to. According to Boland, Mercedes isn't sure what, if any, injuries the recalled airbags could cause, but simply claims there's an increased risk in these particular vehicles. There's been no reported instances of the faulty airbags deploying on a customer and the original issue was found in a production test.

When Android Automotive goes in the dash, Google wins — and automakers lose data

You've gotta hand it to Google for the way the Silicon Valley tech giant has made indelible inroads into the car on multiple fronts. The most obvious is with its pioneering self-driving car technology that's caused car companies to get their act together on autonomous vehicles — and also collaborate with Google. Google has more directly extended its influence and data-mining capabilities into the car with its Android Auto smartphone-projection platform that most major automakers have adopted along with Apple's CarPlay. And now it's preparing to dig even deeper into dashboards by deploying its open-source operating system, Android Automotive, beginning with Audi and Volvo. Volvo recently announced that its next-generation Sensus infotainment system will run Android Automotive as an OS and include Google's Play Store for cloud-based content, Maps for navigation and Google Assistant for voice recognition, which can even command a car's climate control. By embedding Google in the dash, Volvo says owners will get an improved connected experience. "Bringing Google services into Volvo cars will accelerate innovation in connectivity and boost our development in applications and connected services," Volvo senior vice president of R&D Henrik Green said in a statement. "Soon, Volvo drivers will have direct access to thousands of in-car apps that make daily life easier and the connected in-car experience more enjoyable." Having Android Automotive onboard could benefit drivers — and provide a big win for Google, since it opens a deep and lucrative new data-mining vein for the company. But it's a wave of a white flag for car companies when it comes to delivering their own cloud-based content and services. It also represents a massive data giveaway and, for Audi, a reversal of earlier reservations about letting Google get too much access to car data. Not long after Android Auto and Apple CarPlay were introduced in 2014 and most automakers eagerly embraced the technologies, several German automakers second-guessed their decision when they realized what was at stake: data. At a conference in Berlin in 2015, Audi CEO Rupert Stadler said car owners "want to be in control of their data, and not subject to monitoring." A few months earlier, Stadler stated that "the data that we collect is our data and not Google's.
