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.

Brabus to storm Geneva with 800-hp version of Mercedes SL65 AMG

At no point during our recent drive of the 2013 Mercedes-Benz SL65 AMG did we ever think, "You know, this thing sure is slow." After all, Merc's range-topping SL comes fitted with a twin-turbocharged 6.0-liter V12 capable of sending 621 horsepower and 738 pound-feet of torque to the rear wheels. But just in case you're still all "meh" about what the SL65 throws down, Brabus will gladly come to your rescue with this, the 800 Roadster.
As its name suggests, the 800 Roadster ups the V12's power figures to 800 horsepower and - wait for it - 1,047 pound-feet of torque. Don't get too excited, though - that torque number has been electronically limited to a measly 811 lb-ft since, you know, the transmission would probably explode if you tried to put the full force through it. Nevertheless, these represent increases of 79 hp and 73 lb-ft over the standard SL65, and that means the 800 Roadster can shoot to 62 miles per hour in just 3.7 seconds - two-tenths of a second quicker than the Merc its based on. More impressively, hitting 124 mph takes just under 10 seconds, and the droptop will finally top out at an electronically limited - limited! - 217 mph. Holy smokes.
To manage all of that speed, Brabus has engineered a special carbon fiber aero kit that reduces lift, and a unique control module for the SL65's active body control suspension lowers the ride height by one full inch. The 800 Roadster rides on new 20-inch wheels, and a unique limited-slip rear differential was added, featuring a 40 percent locking rate that further enhances performance when you're attempting to control the beast at its limits. Interior upgrades include new leather and alcantara surfaces throughout the cabin, including a leather-clad trunk.

X1, 3 Series power BMW back into global luxury autos sales lead

BMW managed to eke ahead of Audi for the global luxury sales crown in February. According to Bloomberg, BMW saw deliveries swell by 7 percent in February, besting the 3.2 percent jump enjoyed by Audi and giving BMW a 407-unit delivery lead over its rival last month. Mercedes-Benz, meanwhile, continued to falter, with the brand selling some 37,229 fewer machines than BMW, whose factories are running at full capacity to keep up with demand. Models like the X1 (shown above) enjoyed a sales increase of 40 percent in February while the company's bread-and-butter 3 Series jumped by 26 percent.
Mercedes-Benz hopes to stem its continued market share loss with the addition of the entry-level CLA sedan to its portfolio in April. The company is set to roll out an updated version of its cash-cow E-Class at the same time, and a new-generation S-Class will follow along shortly thereafter. Meanwhile, the company is increasing production to meet demand for its A and B-Class models.
