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 plans Audi TT fighter

With the growth in popularity of modular platforms in the auto industry, it's rapidly becoming commonplace to see a company with multiple models that look different but share a significant number of parts underneath. One such an example is Mercedes-Benz's line of compacts, including the A-Class hatchback, CLA-Class sedan, GLA-Class crossover. Two derivatives lacking from German brand's current, small-car range are a coupe and convertible, but that might be changing soon. Mercedes is hard at work on a coupe with 2+2 seating, a liftback roof and styling inspired by the AMG GT, according to Autocar. Daimler Chairman Dieter Zetsche reportedly supports the idea, too. The new two-door could be on the road as soon as 2019 to target models like the Audi TT and BMW 2 Series, and a convertible version might follow later. This little, luxury two-door would ride on Mercedes' next-gen, front-wheel-drive compact platform, according to Autocar. It reportedly allows the German company to vary a model's size more than the current version and can better adapt to hybrid powertrains. A previous report also suggested the coupe and convertible might use this improved chassis, if they got the green light. Of course, a Mercedes model is hardly complete without an AMG version, so that would also be a possibility. According to Autocar, the performance brand's 2.0-liter four-cylinder could see output pushed to 400 horsepower compared to the current 355-hp unit. Earlier rumors also indicated a more powerful version of the boosted mill might be on the way. With Autocar backing all this up only with unnamed sources, the rumors should probably be taken with a grain of salt at the moment. However, a small coupe from the brand doesn't seem entirely impossible. After all, after two-door versions of the C-,E-, and S-Class, why not a smaller one, too?

Mercedes has X6 in its crosshairs with the GLE Coupe

In the last month, Mercedes-Benz has taken the sheet off two versions of its GLE Coupe: the 450 AMG and Mercedes-AMG GLE63 S. The models represent the German brand's shot across the bow at the BMW X6 in the luxury-crossover-four-door-coupe segment, including the high-performance M version of the bodystyle. Not much separates the styling between the two versions. Both feature sweeping arches over the hood and roofline to create their coupe-like appearance. Up front there are huge air intakes with a wide grille on top that's bisected by the brand's traditional star. The AMG version tweaks that look with the division's A-wing grille. At the rear, there are wraparound taillights and a chrome strip. The higher performance version also sports a modified diffuser and air outlets. No matter which one buyers choose, they get a healthy amount of power nestled under the hood. The 450 AMG packs a 3.0-liter, twin-turbo V6 with 362 horsepower and 384 pound-feet of torque with a nine-speed automatic. Opting for the GLE63 means a massive boost with 577 hp and 561 pound-feet from a 5.5-liter twin-turbo V8 routing through a seven-speed auto gearbox. Either way, customers get Merc's 4Matic all-wheel drive system. The luxury crossover coupe segment is often maligned for looking awkward, but Mercedes clearly sees room to grow there.
