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.

177k Toyota Camry Hybrids being recalled for brake issue

It looks like Consumer Reports might be getting part of what it wants regarding the Toyota Camry Hybrid and its braking system. Toyota is issuing what it calls a limited service campaign, rather than a full recall, covering about 177,500 of the hybrid sedans from the 2007 through 2011 model years because of an issue with the cars' brake fluid reservoirs.
The models have a filter separating two chambers of the brake fluid reservoir, and the part can get clogged over time. If this happens, the fluid level in one of the chambers can get too low and eventually cause the power assist to fail. There are multiple warning lights on the dashboard that illuminate over time if the filter gets obstructed, though. The company is replacing the entire reservoir with an improved unit, and the fix takes about two hours to perform.
Consumer Reports recently began asking for a recall on these models for the potentially clogged filters. The magazine also reported a second issue with the ABS brake actuator that could lead to a difficult to depress brake, but Toyota has increased the warranty on the part to 10 years or 150,000 miles.

BMW Z4 and Toyota Supra replacement spied in the snow

The new BMW Z4 and Toyota Supra will be the fruit of a marriage of convenience, born from the former's chassis and powertrain expertise and the latter's giant coffers full of money. The final product, spied testing in frigid temperatures in parts unknown, will have specific bodies depending on which brand it carries, so it won't be a simple rebadging exercise. This mule sports a softtop, rather than a retractable hardtop like the existing Z4. Whether this represents a final decision about what type of roof will be fitted to the production model is unclear. What we have heard, repeatedly, is that the chassis and the entire driveline will be pure BMW for both models, and that the main difference will be brand-specific sheetmetal. There are even rumors that an all-wheel-drive version will be available, or that the model will be available as a hybrid using Toyota's expertise in that arena. It's been a long wait since the memorandum of understanding that lead to the mule you see above was signed in 2012, and we had expected an announcement that the roadster would go into production by the end of 2015, but that time has come and gone. Perhaps we'll find out more at one of the upcoming auto shows. Geneva is coming up in March, after all.
