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 reveals F 015 Luxury in Motion concept at CES [w/videos]

Whatever you think of the idea, autonomous vehicles are emerging as the way of the future in the automotive industry, and Mercedes is showing its vision for that driverless destiny with the F 015 concept at CES this week. Billed as Luxury in Motion, the F 015 first popped onto our radar back in October when it was snapped under wraps and then again when the German automaker released the first teaser image previewing its silhouette, but has now taken center stage at the electronics expo in Las Vegas. So what is it exactly, you ask? Well, aside from being entirely autonomous – bringing together a suite of advanced technologies to take the driver out of the equation – it's also big. It's marginally larger than an S-Class, in fact, and with a more spacious one-box form that turns the cabin into a rolling living room. That's where you'll find four individual bucket seats that swivel towards each other, and pivot towards the giant doors for ease of ingress and egress. The doors open a full 90 degrees and the back ones swing suicide-style like on a Rolls-Royce, but without a B-pillar to get in the way. An array of six display screens turn the cabin – clad in wood, aluminum, glass and leather – into an all-enveloping "digital arena," with gesture-based controls, touch-sensitive screens and eye-tracking technology. Made of carbon fiber, aluminum and high-strength steel, the concept is some 40-percent lighter than a conventional automobile of its size. And while Mercedes isn't saying exactly what would provide the motivation (and to what effect), it does state that "the bodyshell of the F 015 Luxury in Motion was designed to allow the impact-protected integration of an electric drive system with fuel cell." The concept follows the debut of the Future Truck 2025 concept big-rig at the IAA Commercial Vehicles show in Hannover a few months ago, and is earmarked to make transportation through and between the world's growing cities a smoother, safer and less human-intensive ordeal. Whether that's the kind of future you want to live in is another matter, but you can scope it out in the videos and press release below and in the extensive gallery of images above for a closer look.

Mercedes-Benz C-Class scores well in TUV lifecycle analysis

Mercedes-Benz drivers and treehuggers don't always go hand in hand, but, like a lot of other companies, the German automaker is looking to boost its green cred. This time, it's all about the car's lifecycle carbon footprint. The Daimler AG unit is using its new C-Class sedan as an example of how it's making progress in that department. Mercedes-Benz, citing the inspection authority TUV Sud, says the 2015 C-Class has a 10-percent lower lifecycle carbon footprint than its 2014 predecessor, based on driving about 125,000 miles over the life of the car. About 95 percent of the car (by weight) is recyclable, slightly higher than the average for most vehicles, and the model has upped its amount of recyclable materials up by 23 percent and increased its use of "natural materials" by 55 percent. Better aerodynamics also helps things out on the fuel-economy front, Benz says. Taking a longer view, the 2015 C-Class's carbon footprint is 28 percent better than the 2007 version that launched the vehicle line. The 2015 C-Class hasn't received a fuel-economy rating from the US Environmental Protection Agency, which tagged the 2014 C350 with a combined fuel-efficiency rating of 24 miles per gallon from its 3.5-liter 6-cylinder engine. Check out Mercedes-Benz's press release below and find the Autoblog First Drive impressions here. TUV Environmental Certificate: The new C-Class makes its mark with an exemplary life cycle assessment Stuttgart, Mar 28, 2014 The C-Class sets efficiency benchmarks for its class, helped by an intelligent lightweight concept, excellent aerodynamics and new, frugal engines. The neutral inspectors from the TUV Sud technical inspection authority have confirmed the high level of environmental compatibility of the new Mercedes-Benz C-Class. Besides a sensuous, clean-cut design, a top-class interior and a host of technical innovations, the premium saloon also boasts an exemplary life cycle assessment, which is why it has been awarded the Environmental Certificate in accordance with the ISO 14062 standard. Professor Dr. Herbert Kohler, Chief Environmental Officer at Daimler AG: "Our engineers have pulled out all the stops in an effort to lower fuel consumption while at the same time further accentuating the car's sporty character. By employing an intelligent lightweight design with a high proportion of aluminium, for example, it has been possible to make the new C-Class up to 100 kilograms lighter than its predecessor.
