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.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

Nissan-Renault and game developer plan driverless ride-hailing

TOKYO - The Nissan and Renault alliance plans to launch driverless ride-hailing and ride-sharing services in coming years, as the automakers look beyond making and selling cars to survive an industry being quickly transformed by new services. Automakers are leveraging expertise in automated driving functions for mass-market cars to develop mobility services, as they compete with tech firms such as Alphabet Inc and Uber in the fast-growing "pay-per-ride" market which threatens to hit demand for car ownership. Ogi Redzic, head of Nissan-Renault's Connected Vehicles and Mobility Services division, said the alliance would begin self-driving services based on its electric cars "certainly within 10 years," though not likely before 2020. "We think that the big opportunity for us is in automation, electric vehicles and ride-sharing and hailing together," Redzic said in an interview on Thursday. Nissan and Renault join a small group of automakers aiming to enter the ride-hailing market, which Goldman Sachs last month estimated would grow eightfold by 2030 to be five times the size of the taxi market. Redzic said the Japanese and French partners were testing self-driving vehicles, and that any service would run on pre-mapped courses with predetermined pick-up and drop-off points. The two automakers are developing the system with Japanese game software maker DeNA Co Ltd and French public transport operator Transdev SA. German rival BMW AG is also testing autonomous vehicles for use in ride-hailing services, while Uber has been developing self-driving technology. U.S. tech firm nuTonomy Inc and ride services company Lyft Inc, which counts General Motors Co as a major shareholder, this month announced they would begin piloting an autonomous vehicle ride-hailing service in Boston. Redzic said to market a self-driving service, regulations need to change to allow driverless cars on roads. At the moment, most global jurisdictions do not expressly authorise vehicles to operate on regular roads without a driver. "It doesn't just depend on us," he said. "To become fully driverless you need laws to change." Reporting by Naomi TajitsuRelated Video:
