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.

Mercedes-Maybach SUV concept headed for Beijing reveal in April

Mercedes-Benz has toyed with the idea of a Maybach SUV for at least 11 years. According to Autocar, we'll finally see a concept with production intent at the Beijing Motor Show next month, the luxury SUV slated for market release next year. As has been the rumor for at least six years, the Maybach people carrier will be based on a stretched version of the GLS, which moves to the company's new Modular High Architecture with the 2019 model. Back in 2007 when Maybach was its own brand and selling roughly 300 units per year, Car magazine reported that brand chiefs were interested in convertible versions of the Maybach 57 and 62 sedans, and an SUV. Maybach built a one-off concept based on the GL — the former GLS-Class — in 2009, but never took the idea further. The rumor popped up again in 2014, then in 2015, reaching not-if-but-when status early last year. A decade on, it's finally time to play the hand. Even though the super-luxe SUV would sit on a stretched version of what is already a three-row SUV, it's reasonable to expect the Maybach SUV will only get two rows. That would give designers plenty of extra room for seating luxury and amenities even beyond the S-Class Maybach. On the other hand, if Mercedes sticks to the rough Maybach playbook so far, a triple-row Maybach would be the only such SUV in the mid- to upper-six-figures. The S-Class 560 4Matic starts at $102,990, the S 560 4Matic Maybach starts at $168,600. Applying that spread to the $94,500 GLS 550, you'd land around $160,000 before adding the markup for a new generation. That kind of starter pricing might make a great tweener proposition. Mercedes could focus on a range of buyers who want to go upscale from the $125,300 AMG GLS 63, without needing to worry — yet — about challenging Bentley and Rolls-Royce. Power is said to come from some version of the company's oft-applied 4.0-liter twin-turbo V8 that puts out 462 horsepower in the S 560, but the 3.0-liter inline-six hybrid in the S 560e is under consideration. We'll know next month, when the lightly veiled concept takes the stand in China. The full-on production version should get an introduction at this year's L.A. Auto Show. Related Video:

Mercedes-Benz S-Class spied once again

As evidenced by how little camouflage the next-generation Mercedes-Benz S-Class has been caught wearing lately, it can't be too much longer until the car will get its official debut. In our newest shots of the yacht-sized luxo sedan, the cladding still covers up the headlights, front fascia and most of the rear end, but we finally have an almost undisguised look at the rest of the car's lines.
Considering previous spy shots had more camo that better (or fully) concealed the S-Class' body, some of the more obvious things we see in these images include the prominent grille, the CLS-Class-inspired bodyside creases, the pointed trunk opening and, most interestingly, a lack of fancy exhaust outlets. Unlike other S-Class prototypes we've seen, this car does not have integrated outlets, but it does have two pipes on the left side of the car. All current S-Class models in the US and Europe feature a dual exhaust layout on each side of the car, so while some of our questions about the car get answered, it would appear that more are just arising.
