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 unveils ZEOD RC at Nismo HQ in Japan [w/videos]

At Le Mans this past summer, Nissan unveiled the first prototype for the ZEOD RC, a new hybrid racecar which it intends to field at the famous French endurance race next year. Four months have passed since then, totaling eight month of development, and now Nissan has revealed the final form at the headquarters of its Nismo racing division.
The updated Nissan ZEOD RC benefits from a more streamlined shape with optimized cooling and improved aerodynamics. Although billed as an electric vehicle and not a hybrid, the ZEOD RC pairs a 1.6-liter turbo four with a pair of electric motors. Its regenerative braking system is derived from the Leaf RC, and after 11 laps, it's said to be capable of taking another around the Circuit de la Sarthe under electric power alone, making it the first racecar capable of doing so. Nissan has further stated that it hopes the lessons it garners from this project will help in its development of a new LMP1 to challenge for overall victory at Le Mans in the near future.
The ZEOD RC will be on display at Fuji Speedway this weekend during the six-hour FIA World Endurance Championship race there, after which it will continue its development at the hands of former GT1 champion Michael Krumm and gamer-turned-racer Lucas Ordonez, who will be getting it ready for (and possibly drive it at) next year's 24 Hours of Le Mans. There it will compete - faster than most GTE sportscars, says Nissan - in the Garage 56 spot that once was awarded to the DeltaWing, which Nissan sponsored and to which the ZEOD RC looks conspicuously similar.

Takata air bag recall list

The National Highway Traffic Safety Administration confirmed yesterday that 33.8 million vehicles with Takata airbags are going to be recalled. It's the largest recall in automotive history. The already record-breaking rate of automotive recalls this year shows no signs of slowing down, especially since millions of cars with defective airbags made by global supplier Takata are under ongoing scrutiny. The federal government is warning owners that inflator mechanisms in the air bags can rupture, causing metal fragments to fly out when the bags are deployed. The faulty air bags have already been blamed for multiple deaths. How do you know if your vehicle is safe? The National Highway Traffic Safety Administration released an updated list of vehicles under recall. Sometimes however, the government's website will crash and the list may not be complete. Check your VIN at the NHTSA website to make sure. The list of cars affected by the recall has not been released, but seem to span multiple models over the years for many of the automakers.
