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.

Renault-Nissan reportedly partnering with Waymo on self-driving cars

The Renault-Nissan-Mitsubishi alliance will tie up with Alphabet Inc's Waymo to develop autonomous taxis and other services using self-driving vehicles, the Nikkei reported on Tuesday. Google's self-driving car company Waymo will work with the carmakers and announce a plan for the arrangement as early as this spring, the business daily reported. The partners are considering the joint development of unmanned taxis using Nissan vehicles and a system that handles reservation and payments, Nikkei said. A spokesman at the Renault-Nissan-Mitsubishi alliance, Nick Twork, said, "This (Nikkei) story is based on rumors and speculation. We have nothing to announce." Waymo did not immediately reply to a request for comment. Last month, Nissan Motor Corp said its board remained committed to the carmaker's alliance with Renault SA and Mitsubishi Motors Corp, after directors met to discuss the ongoing investigation into former chairman Carlos Ghosn and ways to bolster governance. Among the companies developing autonomous driving technology, Waymo is considered to be far in the lead in terms of test-fleet miles driven. It operates hundreds of vehicles in 25 U.S. locations, and is already operating a taxi service with paying customers in Chandler, Ariz. Related Video:

Carlos Ghosn's arrest casts doubt on future of Renault-Nissan alliance

For years, France's Renault and Japan's Nissan struggled to make money in the global auto business. Then came Carlos Ghosn, a Renault executive who helped to orchestrate an unprecedented transcontinental alliance, combining parts of both companies to share engineering and technology costs. Now Ghosn's arrest in Japan for alleged financial improprieties at Nissan could put the nearly 20-year-old alliance in jeopardy. Ghosn, 64, born in Brazil, schooled in France and of Lebanese heritage, is set to be ousted this week from his spot as Nissan chairman. He could also lose his roles as CEO and chairman of Renault, threatening the alliance formed in 1999 that's now selling more than 10 million automobiles a year. He's been "the glue that holds Renault and Nissan together," Bernstein analyst Max Warburton wrote in a note to investors. "It is hard not to conclude that there may be a gulf opening up between Renault and Nissan." In fact, Nissan's investigation into alleged misconduct by Ghosn is expanding to include Renault-Nissan finances, sources told Reuters — in a further sign that Nissan may seek to loosen its French parent's hold on their global carmaking alliance. Nissan told Renault's board on Monday it had evidence of potential wrongdoing at Renault-Nissan BV, the Dutch venture overseeing alliance operations under Renault's ultimate control, three people with knowledge of the matter said. Renault's board planned to meet Tuesday to discuss Ghosn's fate. "Carlos Ghosn is no longer in a position where he is capable of leading Renault," French Finance Minister Bruno Le Maire told France Info radio, calling on Renault's board to meet "in the coming hours" to set up an interim management structure. The French government owns 15 percent in Renault and has a say in its operations. Nissan's board is to meet Thursday to consider Ghosn's fate. Nissan has said it will dismiss Ghosn after he was arrested for allegedly abusing company funds and misreporting his income. That opens up a leadership void at the entire alliance, for which Ghosn officially still serves as CEO and chairman. Ghosn added Mitsubishi to the alliance two years ago after the tiny automaker was caught in a gas-mileage cheating scandal. Renault owns 43.4 percent of Nissan, which owns 15 percent of Renault, with no voting rights in a partnership that began in 1999. Since 2016, Nissan has held a 34 percent controlling stake in Mitsubishi Motor Corp.
