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.

St. Louis man charged in killing of Illinois college student

A St. Louis man has been arrested and charged with murder in the slaying of a 19-year-old Illinois college student who went missing while trying to sell his sports car on Craigslist, authorities said. Capt. Tim Fagan of the Florissant, Missouri, police department said at a news conference Wednesday night that 24-year-old Michael Gordon was taken into custody Tuesday and was being held at the St. Louis County jail in lieu of $1 million bond. Gordon has been charged with first-degree murder and armed criminal action in the death of Taylor Clark, a sophomore engineering student at Southern Illinois University-Edwardsville. Fagan, the deputy commander of the Major Case Squad of Greater St. Louis and lead investigator in the case, said police arrested Gordon after his name was found in emails Gordon traded with Clark about the car Clark was trying to sell. Investigators said the two did not know one another before they met. Police say Gordon is an employee of a truck driver training center in the St. Louis suburb of Hazelwood, Missouri, not far from where Clark's 2007 Nissan 350ZX and body were found Tuesday. It was not immediately clear whether Gordon has an attorney. Clark, who is from the southwestern Illinois town of St. Jacob, was reported missing by family members on Monday. Authorities say he was last seen by his girlfriend. "Our hearts and minds are with Taylor Clark's family and friends as they cope with this tragic loss," SIU-E Chancellor Julie Furst-Bowe said in a statement issued Wednesday. "At a time of the year when the new spring season brings the promise of brighter days ahead, and commencement provides unending potential for so many of our students, it is truly sad that Taylor had his bright future taken away." The Belleville (Illinois) News-Democrat reported that Clark worked at a convenience store in Troy, where a candlelight vigil was scheduled for Wednesday night. A similar vigil was held Tuesday night on campus. Clark's death comes during the same week as a Monday court hearing in St. Charles County in which a 23-year-old man was sentenced to life in prison for fatally stabbing a 45-year-old St. Louis man during an encounter and planned robbery in 2012 that was set up through a Craigslist ad. On the same day of the hearing, Fairview Heights, Illinois, police unveiled a "safe exchange zone" on its parking lot, complete with security cameras, to help citizens safely broker online transactions with strangers.

Is 120 miles just about perfect for EV range?

When it comes to battery-electric vehicles, our friend Brad Berman over at Plug In Cars says 40 miles makes all the difference in the world. That's the approximate difference in single-charge range between the battery-electric version of the Toyota RAV4 and the Nissan Leaf. It's also the difference between the appearance or disappearance of range anxiety. The 50-percent battery increase has zapped any lingering range anxiety, Berman writes. The RAV4 EV possesses a 40-kilowatt-hour pack, compared to the 24-kWh pack in the Leaf. After factoring in differences in size, weight and other issues, that means the compact SUV gets about 120 miles on a single charge in realistic driving conditions, compared to about 80 miles in the Leaf. "The 50 percent increase in battery size from Leaf to RAV has zapped any lingering range anxiety," Berman writes. His observations further feed the notion that drivers need substantial backup juice in order to feel comfortable driving EVs. Late last year, the Union of Concerned Scientists (UCS), along with the Consumers Union estimated that about 42 percent of US households could drive plug-in vehicles with "little or no change" in their driving habits, and that almost 70 percent of US commuters drive fewer than 60 miles per weekday. That would imply that a substantial swath of the country should be comfortable using a car like the Leaf as their daily driver - with first-quarter Leaf sales jumping 46 percent from a year before, more Americans certainly are. Still, the implication here is that EV sales will continue to be on the margins until an automaker steps up battery capabilities to 120 or so miles while keeping the price in the $30,000 range. Think that's a reasonable goal to shoot for?
