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 Juke

I didn't always like the Nissan Juke. When it launched in 2010, I just couldn't get over the way it looked – it came across as super weird, and kind of hideous at first blush. But I slowly warmed up to the funky little crossover/hatchback/thing, and after spending some time behind the wheel, I really learned to love Nissan's small wonder. It's a genuine hoot to drive, offering hot hatch-like thrills in a package that doesn't look like anything else on the road. The Nismo and RS models that followed only increased my ardor for the turbocharged Juke, and now, I find myself smiling whenever I see one of these little guys bombing down the road. Going into 2015, Nissan hasn't really made major changes, but there are a host of smaller improvements on hand to make it a more well-rounded vehicle than ever before. And to up the funk factor for the new year, there are a slew of customization options now available to customers through the Juke Color Studio – for better or worse. Following my first drive of the third-generation Nissan Murano in Napa Valley, I took the refreshed Juke for a spin to see if the 2015 model year improvements still make for a car that's good to drive and easy to use, while bursting with the same personality that slowly won me over in the first place. Drive Notes Powering the Juke is the same turbocharged, 1.6-liter inline-four as last year, with 188 horsepower and 177 pound-feet of torque on tap. I've always liked this engine – it's punchy and feels good when being worked via the 2014 model's six-speed manual transmission. There's lots of power down low, with a nice bit of boost mid-range through each gear. Altering the drive modes between Normal and Sport heighten this, and honestly, the turbo/manual setup in this front-wheel-drive Juke was kind of hilarious – a real treat. Sadly, Nissan will no longer offer the manual transmission on non-Nismo Juke models for 2015, so you're stuck with the continuously variable transmission. Bummer. In sport mode, the usually good Xtronic CVT tends to rev high and hold itself there – a tendency of older such transmissions that's seriously off-putting, especially for enthusiasts. Still, the Juke is available with a choice of either front- or all-wheel drive. The FWD Juke is fun, offering decent amounts of grip with a hint of predictable understeer. But I've always liked the four-season factor of the AWD Juke.

Nissan's autonomous cars could drive in US first, maybe by 2020

Future shock could be just six short years away, and coming first to the US. Nissan says it might start making autonomous versions of its cars available in the US by 2020, before the tech hits the road in other countries. The Japanese automaker is in extensive discussions with regulators from California, the best-selling state for the Leaf battery-electric vehicle, for allowing self-driving vehicles to be on its roads, Hybrid Cars says, citing a conversation with Nissan executive Andy Christensen at the recent Detroit Auto Show. Many decisions need to be made between now and then, given the hurdles related to issues such as regulations, liability, safety and technology - and Christensen said the first wave of self-driving vehicles would be able to do their thing only on the highway. The vehicle of choice is most likely to be the Leaf because it's completely battery operated, making the conversion to autonomy that much easier. Last summer, Nissan chief Carlos Ghosn first promised production autonomous cars by 2020. The automaker has teamed up with MIT, Stanford, Oxford and others to extensively test its "Autonomous Drive" concepts since then. Late last year, Nissan tested a self-driving Leaf on Japanese public roads. Nissan is not alone promoting autonomous driving as a way to increase safety, fuel economy and traffic flow, just some of the reasons why the idea may be the wave of the nearer-than-we-thought-future. For example, the company says 93 percent of accidents are caused by driver error.
