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.

2014 Mercedes-Benz E-Class lineup shows its freshened face

Mercedes-Benz showed us its redesigned 2014 E-Class more than a month ago, but the Detroit Auto Show finally gave us a chance to see the full family of mid-size luxury cars and wagons in the flesh. Dieter Zetsche introduced the cars, including sedan, coupe, convertible and station wagon, on stage showing the stylish new design direction.
The wagon and sedan versions (shown as the E400 Hybrid above) will go on sale this spring, while the coupe and cabriolet will hit showrooms over the summer. Check our new gallery of live shots for the entire 2014 E-Class lineup, as well as the previously released press release below.

Mercedes pays tribute to 1955 Mille Miglia with special-edition SL

The Mercedes-Benz SL is one of the longest-running nameplates in the business, and its history has been marked with numerous achievements. But few were as impressive as the 1955 running of the Mille Miglia, and Mercedes pays tribute to that race and the results it achieved there with this latest special-edition roadster. Called the SL Special Edition Mille Miglia 417, this roadster starts with the eight-cylinder SL550 with dynamic stability management and adaptive damping and adds on several highlights. Red trim adorns the front spoiler, the stripe across the matte carbon rear spoiler, the brake calipers and the rims of the black AMG Performance wheels. The red pieces accent the matte black paint, while the interior features AMG Line sports seats with carbon-finish leather and red trim, along with a red and black nappa leather steering wheel and carbon trim. The SL arrives 60 years after the Mille Miglia in which a 300 SL driven by American gentleman racer John Fitch - bearing the number 417 and starting at 4:17 a.m. - led a 1-2-3 class finish, landing fifth overall and leaving many purpose-built racers in the dust. The special edition is confirmed for the US, arriving this fall with pricing to be announced closer to launch. SPECIAL EDITION SL "MILLE MIGLIA 417" Exclusive SL passion February 17, 2015 - Stuttgart -- Mercedes-Benz celebrates the 60th anniversary of a memorable motor racing success with an extraordinary special model of the SL Roadster. Its name commemorates the unexpected victory of a 300 SL in the production sports cars class at the 1955 "Mille Miglia", one of the world's most challenging long-distance races. What's more: the SL Special Edition "Mille Miglia 417" provides a special experience of the unique symbiosis of maximum comfort and motor racing spirit that traditionally characterizes every SL. The Special Edition adds a distinctive note, among other things, with red exterior highlights and fine materials in the exclusively appointed interior. The Mercedes-Benz SL Roadster is more than an icon. Passion shapes its character and its charisma – in the past and today. Legendary vehicles and their stories dominate the model history. One of them is told by the SL that started the famous "Mille Miglia" in 1955 with race number 417 at 4:17 am. After 11 hours, 29 minutes and 21 seconds it had completed the race distance of 1597 kilometres on public roads from Brescia to Rome and back.
