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.

Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

Renault, Nissan officially reboot their auto alliance for post-Ghosn era

Nissan CEO Makoto Uchida looks on as Renault CEO Luca De Meo and Mitsubishi CEO Takao Kato shake hands during a news conference to unveil new agreement between Nissan and Renault on Monday in London.   LONDON — Automakers Renault and Nissan on Monday formalized their reboot of a relationship that had grown rocky, culminating in the spectacular fall of top executive Carlos Ghosn, who had led successful turnarounds at both companies before his arrest and daring escape. The boards of both companies approved equalizing the stake each automaker holds in the other to 15%, bringing a better balance in the French-Japanese alliance, which also includes smaller Japanese carmaker Mitsubishi Motors Corp. The uneven shareholdings had been viewed at times as a source of conflict. Until now, Renault Group of France owned 43.4% of Nissan Motor Co., while the Japanese automaker owned 15% of Renault. “We have been waiting a long time for this moment,” Renault board Chairman Jean Dominique Senard said at a news conference in London, calling it a “new era." Nissan intends to invest up to 15% in Ampere, RenaultÂ’s electric vehicle and software entity in Europe that Mitsubishi also will consider investing in. The automakers said they will collaborate in markets worldwide, including Latin America, Europe and India. The moves come at a time when the extremely competitive auto industry is undergoing a major shift toward electric vehicles and other environmentally friendly models. The long speculated changes to the carmaker alliance were announced a week ago. Shares equivalent to a 28.4% stake will be transferred to a French trust, according to the companies. Renault, whose top shareholder is the French government, and Nissan agreed on an orderly sale of that stake, although there will be no deadline. Nissan Chief Executive Makoto Uchida vowed to take the alliance to “the next level of transformation” to adapt to a new era. “This is not a choice but a need,” he said. In theory, partnerships are a good way for automakers to cut costs by sharing parts, production and technology, especially when the industry is going through such dramatic change with EVs. That also means that, once formed, ending an alliance can be difficult because the companiesÂ’ development, manufacturing and products get so closely tied together. Still, partnerships can stumble because of the different corporate cultures of the automakers, especially when it involves a meeting of the West and East.
