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: Nissan and Endesa launch V2G project; BMW denies Apple will use i3

Nissan and Endesa will work together to deliver a mass-market vehicle-to-grid (V2G) system. The technology would allow users to charge their vehicle during off-peak hours, and sell energy back to the grid during periods of high demand. The two companies are looking to launch V2G technology in Europe, as well as exploring second-life projects using retired EV batteries for stationary energy storage. V2G allows users to lower the cost of ownership of their EV, and also helps stabilize the grid, particularly in countries that use a large amount of renewable energy. Endesa will demonstrate its V2G technology system in Madrid on March 12. Read more from Nissan. BMW denies reports that Apple will build a car based on the i3. German magazine Auto Motor und Sport said that such a deal was in the works, and that the Apple car could be sold by Apple and serviced by BMW. "We are in regular talks with companies from the IT and telecommunications sector, including Apple, concerning topics like connected vehicles," says BMW. "Developing or building a car is not a topic of these discussions." Anonymous sources say that Apple could have a car available for production in 2020. Read more at Automotive News Europe. BluepointLondon will take over the management of 60 EV charging stations from Transport for London. The 60 chargers are in the boroughs of Southwark and Sutton, and Bluepoint expects to take over management of charging infrastructure in other London boroughs as well. "A better maintained and more extensive charging infrastructure will mean more drivers are able to use electric vehicles and join the early-adopters who are already helping London reach lower emissions level," says BluepointLondon Director Christophe Arnaud. "We are very excited to be playing our part." BluepointLondon aims to manage 6,000 charging points in London by 2018. Read more in the press release below. Efficient Drivetrains, Inc. (EDI) offers plug-in hybrid conversions for GM light-duty trucks. The PHEV drivetrain offers all the performance of the original model, but reduces consumption and emissions by as much as 80 percent. It offers 30 to 40 miles of all-electric range plus enough energy to act as an idle-free power supply for tools and the like without depleting range. The EDI drivetrain can even be used to charge other EVs. Says EDI's Charlie Travis, "The light duty truck class is an important and high-volume vehicle category for fleet owners.
