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.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

2024 Mercedes-Maybach EQS 680 SUV tops $180,000

The 2024 Mercedes-Maybach EQS 680 SUV is staking claim to the "next era of driving pleasure," but that pleasure will come at a steep price. The company officially announced Wednesday that the super-lux, battery-electric SUV starts at $181,050 (assuming the $1,150 destination fee doesn't increase for 2024) — $50,000 more than the standard Mercedes-Benz EQS 580. And you can order one starting today.  While U.S. figures are still partially up in the air, we do have some preliminary specs. To go with its 649-horsepower output, the EQS 680 SUV was rated at 600 km of total range on the WLTP cycle, which works out to about 373 miles. While Mercedes-Benz doesn't have EPA figures to offer, the EQS 580 is rated at approximately 340 miles with the same pack and a very similar (613 km) WLTP-certified range. 0-60 comes in just 4.1 seconds on the way to a top speed of 130 MPH. Charging the EQS 680 SUV back up from 0% will take a bit longer — nearly 13 hours on a Level II AC charger — but DC fast charging (10-80%) takes just 31 minutes at its max throughput rate of 200 kW.  The Mercedes-Maybach EQS 680 SUV is available with five different two-tone color combinations. All of the two-tone options will feature the lighter color on the bottom half of the SUV, since the darker tone up top better accentuates the vehicleÂ’s aerodynamics. Maybach-specific design details include vertical metal-look lines in the EQSÂ’ faux grille and a Mercedes-Benz star ornament on the hood.  ThereÂ’s a Maybach logo on the D-pillar and the taillights have a unique running light pattern. Mercedes-Benz says 21-inch wheels are standard for now; larger 22-inch wheels, as well as a sixth two-tone paint option, will come later. Related video: This content is hosted by a third party.
