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 G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.

Brabus shows S65 Rocket 900 Desert Gold Edition in Dubai

If it packs 900 horsepower and it's painted gold, you're probably looking at the Brabus Rocket 900 Desert Gold Edition, an extreme S-Class that debuted at the Dubai motor show. The "normal" S65 sports a 6.0-liter twin-turbo V12 pumping out 621 horsepower and 738 pound-feet of torque, and that would have been enough for most. But Brabus is there to satisfy those for whom too much is never enough, and so it revealed the Rocket 900 at the Geneva Motor Show earlier this year, raising the S65's output to 887 hp and 1,106 lb-ft of torque. Throw in upgraded aero, suspension, rolling stock, exhaust, and a fully refitted interior, and the Rocket 900 amounts to a complete transformation. Mercedes' 4Matic all-wheel drive system couldn't handle all the twist from the stock S65, so power is transmitted to the rear wheels alone. What sets the Desert Gold Edition apart from the existing Rocket 900 is its gold color scheme. The exterior is swathed in the deep gold paint, the black wheels have a gold rim on them, and even the interior gets gold updates. If you happen to be at the Dubai Motor Show, go check it out. World premiere at the DUBAI INTERNATIONAL MOTOR SHOW 2015 An homage to the Orient BRABUS ROCKET 900 "DESERT GOLD" Edition V12 with 662 kW / 900 HP, 1,500 Nm and 350 km/h plus BRABUS ROCKET 900 – that is the new reference for high performance in the luxury segment.

BRABUS developed the especially exclusive BRABUS ROCKET 900 "DESERT GOLD" Edition, which celebrates its world debut at the DUBAI INTERNATIONAL MOTOR SHOW 2015, as an homage to the Orient, where BRABUS maintains a company branch and a prestigious BRABUS Flagship Store in Dubai. The exclusive high-performance luxury liner is immediately recognizable not only due to its extraordinary "DESERT GOLD" special paintwork. The appearance of this special model is also characterized by BRABUS carbon aerodynamic-enhancement components and shiny black BRABUS Monoblock F "PLATINUM EDITION" 21-inch wheels with gold pin striping. The BRABUS fine leather interior is finished in a combination of gold and black leather. Gold-colored seams in a quilting pattern created specifically for this special model furthermore distinguish the classy interior appointments.
