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.

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.

BMW i8 customized by AC Schnitzer [w/video]

It may not enjoy the kind of factory support that Alpina does (let alone Munich's own M division), but as far as independent BMW tuners go, few have the kind of clout that AC Schnitzer does. Heck, it even won the DTM championship for BMW in its first year back in the series. And now the legendary Bimmer tuner has turned its attention to the i8. The list of Schnitzer's enhancements for the plug-in hybrid sports car is long, but perhaps wisely shies away from messing with the intricate powertrain. Instead the customization options focus on elements like the suspension, rolling stock, aero kit, and interior. AC Schnitzer has dropped the ride height by almost an inch at the front and 0.78 inches at the rear. It's fitted a set of 21-inch forged alloys with five split spokes and low-profile rubber to trim nearly ten pounds off the vehicle's unsprung weight while increasing its contact patch for better grip (albeit likely with higher rolling resistance). There's also a comprehensive rolling kit made of carbon fiber, including front spoiler elements, side skirts, and a rear wing that to our eye looks a little out of place on the i8, though individual customers may disagree. And the interior has been upgraded with aluminum pedals and velour floor mats. Of course customers will be able to pick and choose which elements they'd want to install on their hybrid vehicles, but you can check out the fully spec'd demonstrator in the high-resolution image gallery above and in the video below. (You just may want to turn down your speakers if you're not into German techno-pop.) Revolutionary Sporting Performance and Innovative Design The i8 by AC Schnitzer emphasises the strengths of the plug-in hybrid from Munich The BMW i8 is revolutionising its vehicle class as the first sports car to have the fuel consumption and emission values of a small car. Now thanks to AC Schnitzer, this revolution is being followed by another: the AC Schnitzer special equipment for the BMW i8 emphasises even more clearly the sporting performance and innovative design of the powerful, environmentally-friendly coupe. Lowered by 25 mm at the front and 20 mm at the rear, the i8 by AC Schnitzer hugs the tarmac more closely than the standard vehicle and can therefore develop maximum efficiency and dynamics on the road.
