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.

Nissan Pathfinder, Infiniti JX in transmission safety probe

Nissan may be forced to recall 110,000 Pathfinder and Infiniti JX35 crossovers, due to a number of customer complaints. Consumers report suddenly losing power, with repair facilities blaming the issue on faulty transmission cooler line connections. Both the Pathfinder and JX35 use a continuously variable transmission. As of right now, the only vehicles being investigated are from model year 2013.
Nissan has been cooperating with the National Highway Traffic Safety Administration, according to a report from Reuters, and it has developed a fix for the affected vehicles. It's not clear whether this will develop into a full-blown recall, as there have been no known cases of injuries or crashes. But with a potential 110,000 vehicles prone to sudden power loss, a recall seems to be a likely outcome.

Mercedes and Infiniti confirm joint production in Mexico [w/video]

It's official, folks: After initial reports last week indicated that Mercedes-Benz was preparing to begin assembly at the Nissan plant in Aguascalientes, Mexico, the two parent companies have announced just that. Only instead of using the existing Nissan plant at the site (in operation since 1992), Daimler and the Renault-Nissan Alliance have announced a joint venture to build a new one alongside it.
The latest stage in the growing French-German-Japanese collaboration is part of a new collaboration that will see Infiniti and Mercedes jointly develop and build a line of compact premium vehicles, with the first Infiniti models set to roll off the assembly line in 2017 and the first Benzes to follow a year later. Neither party announced exactly which models that would encompass, but Mercedes already has a robust line of small vehicles (including the A-Class, B-Class, CLA and GLA), and Infiniti has long been toying with the idea of slotting in something smaller below the Q50.
The billion-euro project, split evenly between the two industrial giants, is set to create 5,700 new jobs in Mexico. In addition to the Aguascalientes project, Infiniti and Mercedes are also undertaking joint production of four-cylinder engines (initially for the C-Class and Q50) in Decherd, Tennessee, from which they will be exported around the world. By the time the new factory in Mexico reaches full capacity in 2021, it will have the capability to produce 300,000 vehicles annually. That's on top of the 850,000 vehicles the existing facility is capable of handling.
