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 sues Ferrari-bound F1 engineer for stealing secrets

Mercedes is suing one of its Formula One engineers, one Benjamin Hoyle, claiming he was planning to take sensitive data to a competitor. An experienced powertrain engineer, Hoyle came to Mercedes AMG High Performance Powertrains in 2012 with previous experience at Prodrive and Cosworth. One of four team leaders at the company, Hoyle headed up the performance application department until he notified his employers of his intention not to seek renewal of his contract that expires at the end of this year. Once they found out that Hoyle was switching to Ferrari, the higher-ups at Mercedes reassigned him to other, less sensitive duties, however Hoyle was reportedly discovered accessing race reports and other sensitive data relating to the performance of the team's engines. In response, Mercedes has filed suit against Hoyle, claiming that he "and potentially Ferrari have gained an unlawful advantage." The German automaker is seeking the return of all documents and the payment of its legal fees. It also seeks to prevent Hoyle from working for another F1 team throughout next season. Mercedes AMG High Performance Powertrains is the Daimler's F1 engine division. Based in Brixworth, UK, it was founded back in 1983 together with Ilmor before Mercedes bought it outright. Aside from the company's own works team, the outfit this year powered Williams, Lotus, and Force India, and previously worked with McLaren as well as Sauber. This is not the first time that a case of industrial espionage has emerged in F1. A similar controversy erupted in 2007 surrounding engineers Nigel Stepney and Mike Coughlan. The highly publicized incident became known as "Spygate" or "Stepneygate" and involved the illegal sharing of secrets between Ferrari, McLaren, and Renault.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.
