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.

Aston Martin and Mercedes will share F1 safety car duties

LONDON — Aston Martin is set to join Mercedes next season as a provider of Formula One's official safety cars, according to media reports on Tuesday. Racefans.net reported that Aston Martin would supply safety and medical cars at 12 of the 23 scheduled races in key markets, with the existing Mercedes cars used at the rest. It said Aston Martin's new DBX SUV, which uses a Mercedes-AMG V8 engine, would be used as a medical car. There was no official confirmation from Aston Martin or Mercedes. Sources indicated to Reuters that the report was accurate, however. Mercedes has been the official provider of the cars, which are deployed in the event of an incident or bad weather to keep the field lapping safely, since 1996 but that deal runs out at the end of this year. A shared supply would make sense for both carmakers, who already have close ties. Aston Martin's executive chairman Lawrence Stroll also owns the Racing Point team, who will race as Aston Martin from next season with four times world champion Sebastian Vettel arriving from Ferrari. Mercedes, a part of Daimler, is set to raise its stake in Aston Martin to up to 20% by 2023. Toto Wolff, principal of the Mercedes factory team, also has a private stake in Aston Martin.

Mercedes Unimog poised for Canadian return

The Mercedes-Benz Unimog, the super-duper heavy-duty off-road workhorse vehicle that the German automaker has been making for more than 60 years, may soon be sold in Canada once again after a hiatus. Regulators had taken issue with both their emissions (super torquey diesel engines don't tend to run real clean) and the fact that some folks would take them out on city streets and even highways (these beasts have a top speed of about 25 miles per hour). Now, regulatory officials are considering allowing the Unimog to be sold in Canada again, albeit under strictly off-road driving regulations, Canada's Driving says. In fact, the diesel trucks apparently run a lot cleaner than they used to, while the torque levels remain off the charts. Naturally, some folks are clamoring for them because of their ability to run on just about any terrain. Hans Mross of Vancouver-based Mross Import Service Ltd., which previously imported the Unimog to Canada, told Autoblog he was "99 percent sure" the Unimog would be brought back to Canada. We'd last reported on the Unimog in April 2013, when Mercedes-Benz said it would start selling 10 different versions of the truck.
