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.

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

Recharge Wrap-up: Renault's electric motors, BMW i3 is AM free

Why isn't AM radio offered in the BMW i3? Some drivers – particularly those interested in local traffic reports – have noticed its absence. BMW says that the electromagnetic interference from the electric drivetrain caused poor performance, and that while reception wasn't always terrible, it wasn't up to their standards. Rather than have customers complain to their dealers, who would be unable to do anything for them, BMW has disabled AM reception in the i3. Some customers have hacked their cars in order to enable the AM radio, despite possible warranty issues, and have found the reception to be acceptable. Read more at Green Car Reports. Saab's current parent company, National Electric Vehicle Sweden (NEVS), broke ground for production and R&D facilities in Tianjin, China. The facilities are part of joint ventures with the city of Tianjin and State Research Information Technology (SRIT). In addition to investments of over $190 million from SRIT and Teamsun, NEVS has received $1.6 billion in credit from the Bank of China to develop its business there. The new Tianjin factory will have a capacity of 200,000 new energy vehicles per year. The facility in Trollhattan, Sweden will provide manufacturing planning, training, and product supply for the Tianjin plant. Read more at Green Car Congress, and in the press release from NEVS. Renault is building the new R240 electric motor for the Zoe at its Cleon plant. The plant and its employees, which specialize in the Energy dCi diesel engine, have adapted to produce high volumes of the electric motor as well, including a 6,000 hours of training for the staff and millions of dollars in investments. "We aim to become the leading powertrain plant for the Alliance," says Cleon plant director Mendi Ammad. The plant is capable of producing 50,000 units of the R240 motor per year, with that number expected to double in the future. Read more about the plant and the production process the press release below. NEW ELECTRIC MOTOR STRENGTHENS POWERTRAIN EXPERTISE AT CLEON ZOE's new electric motor, unveiled at the Geneva Motor Show, is a 100% Renault motor manufactured at the French site of Cleon, already specialized in highly technical powertrain production. Until now, the flagship of the Cleon plant was the Energy dCi (130, 140, 160) internal-combustion engine. The diesel unit with advanced technological content has made a name for itself at Groupe Renault, the Alliance and with our partners.
