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.

BMW could have a fuel cell vehicle by 2020

The Ultimate Driving Machine may start emitting water vapor, which may not thrill gearheads but could be good for the environment. BMW may have a hydrogen fuel-cell electric vehicle to sell as soon as the end of the decade, UK's Auto Express says, citing people familiar with the process that it didn't identify. And the model will likely be sold within the i sub-brand that includes the i3 electric vehicle and the i8 plug-in hybrid. "We are working on fuel cell development, but we are not able to comment on vehicle plans at this stage or timing at this point," BMW spokesman Dave Buchko wrote in an e-mail to AutoblogGreen on Thursday. Chatter about a potential BMW fuel-cell vehicle has been getting louder in recent months. Late last year, Autocar reported that BMW was mulling using Toyota's fuel-cell system for a version of what would be called the i5 (all the better to quietly cruise the interstate running up and down the West Coast, we guess). BMW and Toyota have been working together on accelerating the development of fuel-cell technology since 2013. Toyota has since made good on the effort of selling fuel-cell vehicles by introducing the Mirai in Japan last year and is preparing to start sales in California later this year. But BMW has been mum, so far.

The List: Best of proving grounds

Proving grounds are where automakers and enthusiasts alike go to push their vehicles to their mechanical limits. The Rubicon Trail, located in the Sierra Nevada, is the ultimate off-road test, while Germany's Nurburgring is a grueling 13 mile road and track course.
