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.

2015 Nissan GT-R updated with new lights, more refined ride

The Nismo version of Nissan's high-tech supercar may be getting most of the headlines today, but we shouldn't forget that the car on which it's based, the garden-variety GT-R, has been significantly updated for 2015, as well.
What Nissan engineers focused on for the new model year was making the GT-R a more well-rounded GT car. That means dialing some more compliance into the car's very firm suspension for a more comfortable ride, as well as lightening up the steering at low speeds to make urban maneuvering easier. The braking calibration has also been changed to be more linear and smooth when slowing from normal, everyday speeds. Does this mean the GT-R has gone soft? We'll reserve judgment until we drive it, but Nissan claims the new refinements giving the car "multi-dimensional performance."
The GT-R also gets new lighting technology for 2015, including multi-LED headlights that lend the car a new light signature at night, and the LED taillight rings are now complete circles instead of rings of dots. The headlights are also now controlled by an Adaptive Front Lighting System, which sounds similar to other systems that aim light where the car is being turned, but Nissan's system adjusts the angle of the lights depending on vehicle speed - at higher speeds the lights are angled to project their illumination further.

Renault-Nissan has sold more EVs than its next two competitors combined

Nissan may not be doing so hot with sales of its Leaf electric vehicle in the US this year, but the Japanese automaker and its France-based partner Renault still remain the gold standard of electric-vehicle sellers. Thanks to numbers crunched by the good people over at EV Sales, we learn that the Renault-Nissan Alliance has moved more than 265,000 electric vehicles around the world. That accounts for more than a quarter of all the EVs sold worldwide and is more than Mitsubishi's 11 percent share and General Motors' 10 percent share combined. Nissan and Renault surpassed the quarter-million electric-vehicle mark in June. There are shifts afoot, though. Renault-Nissan's global EV market share is only 18 percent this year, and the Alliance is losing share to companies like Volkswagen, BYD, and, to a lesser extent, BMW. That shift can be seen in this year's US sales numbers, where the Nissan Leaf has pretty much plunged down. In fact, with VW and BMW broadening their inventory of plug-in models, Germany can claim the third-place spot in the list of countries with the most "electric" automakers, after China and Japan. The US is trailing, even if many people associate electric cars with California's Tesla. On that note, both Ford and General Motors have lost electric-vehicle market share this year, while Mitsubishi has essentially tread water. GM's numbers (and Nissan's, for that matter) need some context because Americans have been holding off on purchasing a first-gen Chevrolet Volt extended-range plug-in while the automaker readies a new and improved version. All told, Japanese companies have produced the most plug-in vehicles, accounting for 39 percent of the world's market so far, while the US is responsible for about one in four electric vehicles ever made.
