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.

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.

Nissan Leaf hits 3,000 sales in July, Chevy Volt climbs over 2,000

It was a good sales month for both the Nissan Leaf and the Chevy Volt, with the two 'elder statesman' plug-in vehicles reaching numerical milestones in July. The Leaf sold 3,019 units and the Volt crossed the 2,000 sales level for the first time in 2014, hitting 2,020 sales. With Tesla also announcing it is delivering around 2,500 Model S EVs a month (but that's globally, compared to the US-only numbers for the Volt and Leaf we're talking about here) and Ford's plug-in vehicles selling well, we are certainly in a golden moment for EV sales. The Volt was a bright spot for the Bowtie brand last month. For the Volt, the 2,020 units sold represents a 13 percent increase from July of 2013 even thought year-to-date sales are down 8.7 percent this year compared to last year. Overall, total Chevrolet deliveries for July 2014 were up eight percent compared to 2013, so the Volt was a bright spot for the Bowtie brand last month. On the Leaf front, this is only the second time that the EV has sold more than 3,000 units in a month (the other being in May of this year). The year-over-year increase for the Leaf was 62 percent in July and represents the 17th straight month of record sales, as Nissan is more than happy to report each month. Overall, Leaf sales are up 34.6 percent, year-to-date, and Nissan's director of Leaf sales and infrastructure, Brendan Jones, said in a statement that a free public charging incentive was responsible. "Since we launched the No Charge to Charge promotion in the first 10 markets, we've seen a surge in Leaf sales in those areas. Leaf sales in the northeastern US are also picking up with new tax incentives for Massachusetts and Maryland residents." With No Charge To Charge set to expand to 25 markets over the next year, we expect Leaf sales to continue to grow. We will have our monthly look at all green car sales available soon, so stay tuned.
