Nissan promising autonomous car production by 2020

Nissan will bring the autonomous car to consumers by the end of this decade. The announcement was made by CEO Carlos Ghosn at the company's US headquarters in Irvine, CA. Nissan has already begun construction of a dedicated proving ground for the self-driving cars in Japan, with completion targeted for the end of 2014.
Teaming with MIT, Stanford, Oxford and others, Nissan has already outfitted Leaf EVs with the Autonomous Drive (Nissan's brand name for the tech), a suite of new technologies developed from the brand's existing Safety Shield technology. The current iteration of Autonomous Drive uses the Around-View Monitoring system and laser scanners to analyze the environment, while artificial intelligence systems have been installed to help navigate and operate in a changing environment.
While it's easy to say that Nissan will bring the technology to market within the next six or seven years, it's more difficult to say at what price Autonomous Drive will be available. Most remarkable about all of this is Nissan's claim that self-driving cars will be both commercially viable and available at "realistic prices for consumers." It's expecting Autonomous Drive to be available across its range within two vehicle generations.

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 working on unspecified improvements to Carwings in Leaf EV

Fly a little higher, Carwings. Nissan has been using the communication system as a way for drivers of the battery-electric Leaf to do things like use a smartphone start the charging process remotely, check the charging status or find nearby charging stations. The service was one of the tools Nissan was offering to newbie drivers of the first US mass-produced electric vehicle to better familiarize themselves with ideas like recharging your car from miles away. Now, three-plus years into the model's lifetime, Nissan is looking to get more out of Carwings, Wards Auto says, citing Nissan North America executive Robyn Williams. Specifically, Nissan is hoping Carwings will eventually be able to communicate information about the battery's health, or lack thereof (i.e. degradation) to the driver. That issue was made clear a couple of years ago when Leaf drivers in hot-weather locales such as Arizona said their batteries were losing capacity at a faster rate than advertised. Nissan North America spokesman Brian Brockman, in an e-mail to AutoblogGreen, would only say that the automaker "is always working to determine ways to offer more value to customers via telematics systems like Carwings," but declined to be more specific about any particular technological advancements. Nissan debuted Carwings in late 2010, and, among other things, the concept was novel because it let Leaf drivers compare driving efficiency with other Leaf drivers (think of it as a real silent hypermiling contest). The feature had been used as a telecommunications system on a number of Nissan models in Japan for years before being introduced on the Leaf.
