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 updates G-Class including new 4.0-liter twin-turbo V8 [UPDATE]

UPDATE: Information on US availability (including corrected output figures) added to the revised text below. Mercedes has been building (or having Magna Steyr build) the G-Class for an unfathomable 36 years now. Needless to say, the legendary off-roader wouldn't still be around if not for the occasional update here and there, and that's just what the German automaker announced today. The list of enhancements to the iconic Gelandewagen is almost as long as its lifespan, but the most salient point here is the introduction of a new engine. The revised G550 introduces a new 4.0-liter twin-turbo V8, based on the high-performance engine in the Mercedes-AMG GT and C63, but retuned: in this application, it produces 416 horsepower and 450 pound-feet of torque (compared to 453 hp and 440 lb-ft in the GT or 503 and 480 in the GT S). We'd expect that engine to gradually make its way into other models as well. Though the G500 is the only one with a completely new unit, the other engines in the lineup have also been updated. The G350d bumps from 211 hp and 398 lb-ft to 245 hp and 442 lb-ft, the AMG G63 jumps from 536 hp to 563 (torque remains constant at 560 lb-ft), and the top-of-the-line, twelve-cylinder G65 (which we'll be getting Stateside for the first time) now produces 621 hp and a massive 738 lb-ft. Those figures result in a 0-62 time of 8.9 seconds for the diesel, 5.9 for the G500, 5.4 for the G63 and 5.3 for the G65 – which are altogether might impressive for a vehicle as big and boxy as the G-Wagen. All but the G65 now feature stop/start systems to help reduce fuel consumption too. Benz also revised the suspension tuning (while offering optional active dampers) and reprogrammed the ESP, ASR and ABS systems. Inside there's a new instrument cluster, the non-AMG models get new bumpers and flared wheel arches, and there's a bright new array of colors available for the AMG models, which can also be ordered in a new special Edition 463 featuring unique trim inside and out. The revised models will be arriving at US dealers in November, however the diesel model will not be making the transatlantic journey to our shores. The data in the press release below (as well as the images in the gallery above) pertain to the European models, with the correct output figures for the US models amended in the text above.

SRT Viper dukes it out with Mercedes SLS Black Series in new Head 2 Head

In Episode 36 of Motor Trend's Head 2 Head, now that the Corvette ZR1 is no more, Jonny Lieberman has to look overseas to the Mercedes-Benz SLS AMG Black Series for a challenger with similar philosophy to the SRT Viper: long hood hiding a high-horsepower engine set way back, rear-wheel drive, tiny trunks. That puts the Viper's 8.4-liter V10 with 640 horsepower and 600 pound-feet of torque against the SLS AMG's 6.2-liter V8 with 622 hp and 468 lb-ft.
However, the congruences in philosophy and magnitude of numbers doesn't translate to the driving experiences of the two, which are literally and figuratively on different continents. Lieberman gets a handle on the two of them on Northern California roads, Randy Probst then finds out how, and how quickly, they can lap Laguna Seca.
They both get kudos for being improvements on their original sources, but only one of them can take the win. You can find out by watching the video below.
