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.

Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:

Race Recap: 2015 US Grand Prix was wet, wild, and historic

Hurricane Patricia made landfall in Mexico this weekend, and made her presence known throughout the South. For two of the three days of the grand prix weekend it rained non-stop in Austin, so badly on Saturday that qualifying had to be postponed until Sunday morning, and then it only stayed dry enough to conduct the first two sessions. At the end of a tricky, slippery Q2 Nico Rosberg had put his Mercedes-AMG Petronas on the front row, one tenth ahead of teammate Lewis Hamilton. The German had done the best he could to keep his hair-thin chances of a World Championship fight alive. Daniel Ricciardo lined his Infiniti Red Bull Racing chassis in third ahead of teammate Daniil Kvyat, both drivers having moved up a place because Ferrari driver Sebastian Vettel took a ten-spot grid penalty for using a fifth engine and dropped to 13th. Continuing the two-up theme, Sergio Perez and Nico Hulkenberg were fifth and sixth for Force India. After that came variety: Felipe Massa in seventh for Williams, Max Verstappen for Toro Rosso in eighth, Fernando Alonso looking good in the rain for McLaren in ninth, and Romain Grosjean for Lotus in tenth. When the lights went out, Turn 1 set the tone. Pole position is on the outside line at Circuit of the Americas, and Hamilton had got himself far enough under Rosberg by the time the two got up the hill that Rosberg had to stick to the outside through the corner. At the corner exit Hamilton used the entire track, pushing Rosberg wide, their cars touching. As Rosberg left the track and dropped back to fourth, Hamilton radioed to the team to say the contact was unintentional. The two Mercedes' and two Red Bulls animated the front. Rosberg passed Ricciardo at the end of a Virtual Safety Car period employed to let the marshals clean the debris at Turn 1. Kvyat started chasing down Hamilton until the Russian ran wide and let Rosberg and Ricciardo through, then Rosberg ran wide on the next lap to let Ricciardo through. On Lap 15, Ricciardo passed Hamilton through the esses to take the lead. After the first round of pit stops the Aussie still had the lead, followed by Rosberg, Kvyat, Hamilton, and Vettel. Then Rosberg got around to take the lead and Vettel closed in on Hamilton as the Brit duked it out with the Russian. Rosberg showed excellent speed, building up a nine-second gap on Ricciardo, but a Safety Car period erased that when Marcus Ericsson had to park his dead Sauber on the inside of the track after Turn 10.
