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 readying Spartanburg expansion for X7 production

Prior to the debut of the original X5 in 1999, the idea of a BMW crossover might have seemed like heresy. But here we are, fifteen years removed from the Frank Stephenson-penned design, and the Bavarian automaker has expanded its crossover lineup to include the X1, X3, X4 and X6, and it's showing no sign of slowing down.
We recently reported that BMW is planning on slotting an X2 in at the bottom of the range between the X1 and X3, but now it's being widely reported that it's got an even larger one to put in at the top of its utility line. That, of course, would be the X7, a long-rumored three-row model that would give BMW a large family hauler to challenge the Mercedes-Benz GL.
According to The Wall Street Journal, BMW is expanding its assembly plant in Spartanburg, South Carolina, to accommodate production of the X7 alongside the X3, X4 and X5 that it already builds there for local consumption.

BMW jazzes up the Z4 with Pure Fusion Design package

While the new M3 sedan and M4 coupe may be the big news, they're not the only things that BMW has in the cooker. The Bavarian automaker has just announced a new special edition that serves to highlight the Z4 roadster.
Called the Pure Fusion Design package, the specially-equipped Z4 incorporates Nappa leather trim in ivory with brown stitching covering the seats, armrests and door panels. The lower dashboard is done up to match in white, with brown-accented black leather upper dash, window sills, sun visors and instrument surround. A brown leather line accents the interior, with Fineline wood trim.
BMW is offering the Z4 Pure Fusion Design in the unique shade of sparkling brown metallic pictured here, along with other available colors, and customers can combine the package with the M Sport pack as well. Scroll down for the full press release.
