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.

Buick resurrects the Electra nameplate on a science fiction-like electric concept

Buick plans to broaden its range of electric cars in the coming years, and it still owns the rights to the heritage-laced Electra nameplate, so it was only a matter of time before the past and the future met head-on. Buick resurrected the name it used between the 1959 and 1990 model years on a futuristic, battery-powered concept car. Created by a Shanghai-based design studio, the Electra concept takes the form of either a tall sedan or a low crossover, depending on your perspective. While it's not officially a preview of an upcoming production model, it ushers in a design language named Potential Energy that will permeate most of the electric cars the firm will release during the 2020s. It's inspired by a space capsule, according to Buick, so its greenhouse was drawn to resemble a glass pod. Its surfaces are sculpted but not chiseled, and its front fascia wears LED lights with a three-dimensional effect. Fear not: Stylists didn't forget the seemingly obligatory back-lit emblem. Butterfly doors provide access to the cabin, where the space capsule theme continues. Buick packed the Electra with cutting-edge technology features, but it concealed them rather well to avoid a tech overload. The driver faces a rectangular steering wheel that retracts when it's not needed, behind which is a wide, curved screen that replaces all of the buttons, knobs, and switches normally found in a car's interior. An electric motor is far more compact than a comparable four- or six-cylinder engine, so designers were able to carve out a generously sized interior. Engineers embedded technology into the Electra from the project's earliest stage. It's equipped with software named eConnect that supports over-the-air updates, provides on-demand information about a specific trip, and gives details about the various electronic driving aids. An artificial intelligence-powered assistant lets users perform various tasks, such as setting the air conditioning or controlling home devices, with voice commands. Buick noted the Electra offers about 410 miles of driving range thanks in part to the Ultium battery technology developed by General Motors to power a wide selection of electric models, including the Cadillac Lyriq, the GMC Hummer, and a pair of Honda-badged models scheduled to go on sale for the 2024 model year.

Buick teases the next-gen LaCrosse

Buick continues to play coy about the next-generation LaCrosse, but the latest teaser hints at a swoopy profile for the upcoming sedan. While mostly just a silhouette, the teaser does provide a glimpse of the flowing roof and upward crease around the rear fenders – especially handsome touches. The rest of the LaCrosse remains a mystery. The only other part that we've seen is the Avenir-inspired grille, which features a more angular surround and chrome wings jutting from emblem in the center. Styling aside, the brand claims that the sedan is now more engaging behind the wheel thanks to a stronger, lighter chassis and five-link rear suspension. Powertrain rumors are rather vague but suggest the 3.6-liter V6 will be available when the model arrives at dealers in 2016. One thing we know for certain about the LaCrosse is that it debuts at the Los Angeles Auto Show in November. That only leaves a few more weeks for Buick to keep this mystery going. Related Video:
