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.

Here's the 2017 Toyota 86: Don't call it a Scion

After we heard the bells toll for Scion yesterday, we told you that the Scion FR-S will transform into a Toyota. That's right: just a rebadging. The practical question is, which badge? The philosophical question, which we can't answer yet, is where it'll sit in the pantheon of front-engined, rear-drive Toyota sports cars, of which the Supra was the last one to visit our shores, from 1992 until 1998 in its fourth generation. And as if summoned by this conversation, this camouflaged prototype appeared. Our best guess is that this is going to be the US-bound, Toyota-badged version of the Subaru BRZ and all the other 86-badged variants: the Toyota 86 (in Asia, Australia, New Zealand, South America, and South Africa), Toyota GT86 (in Europe and New Zealand again), and Toyota FT86 (in Nicaragua and Jamaica). For simplicity's sake, let's call it a Toyota 86. Peer into the 86's swirly camo, and it looks like the car is going in for a light refresh. The lower intake in the front fascia, if it's representative of a production part, adopts a different shape and is considerably wider and narrower than either the BRZ or FR-S units. It also appears that the turn signal and its surround are reshaped, different than any of the current variants. Changes out back appear mild. The area around the license plate seems to be smoother, and there is likely a predictable light restyle of the bumper skin and defuser under the camo. We don't expect a significant power increase, and certainly not a turbocharger (sorry!), but crossing fingers wouldn't do any harm. Related Video:

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
