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.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.

Germans, Brits and Ferrari's new V12 SUV | Autoblog Podcast #748

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. With the Detroit Auto Show now in the rearview, focus shifts to news that crept up outside of the North American spotlight. The two talk about the new Ferrari Purosangue SUV, then pivot to a discussion about the future of the Dodge Charger and Challenger based on rumors of a new assembly facility. Next, they discuss what they've been driving recently. Byron leads off with anecdotes from his trip to Spain to drive the 2023 Range Rover Sport and his weekend with the VW GTI SE. Next, Greg talks about the ups and downs of the BMW X3 M Competition and Mercedes-Benz GLE450 Coupe.
