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.

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.

Recharge Wrap-up: Nissan Leaf in Puerto Rico, BMW i3 REx tax-free in NJ, BC2BC cancelled [UPDATE]

*UPDATE: Nissan has released a video of the Leaf in Puerto Rico, so we've embedded it below. Envia Systems will develop battery technology for United States Advanced Battery Consortium (USABC), a subsidiary of the United States Council for Automotive Research (USCAR). The $7.7 million contract, co-funded by the US Department of Energy (DOE), involves a 36-month development program focusing on high-energy cathode and anode material for lithium-ion batteries and pouch cells for electric vehicles. The goal, of course, is to create better energy storage for less money in an effort to make commercial EVs more efficient and affordable. For the DOE, this also equates to energy security, energy independence and national security. Read more in the press release at the bottom of the page. The US and China have agreed to work together more closely on EVs, energy and climate issues. US Secretary of Energy Ernest Moniz went to Beijing for the sixth US-China Strategic and Economic Dialogue to meet with leaders. While there, Moniz and Wu Xinxiong of China's National Energy Administration (NEA) signed a memorandum of understanding allowing the DOE and NEA to share information regarding oil reserves. The groups will meet yearly to learn more about how each other manages petroleum stockpiles and policy. Moniz also met with Minister Miao Wei of the Chinese Ministry of Industry and Information Technology and signed an MOU to cooperate on electric vehicles and "related technologies," including the "inter-operability of electric vehicles." Read more at the Energy Department website. August's BC2BC all-electric vehicle rally, billed as the largest gathering of electric vehicles, has been cancelled. The event, which was to include a drive up the entire coast from Mexico to British Columbia with smaller events along the route, failed to bring in the needed sponsorship to hold the rally for its third year. A Facebook post from organizer Tony Williams also cited loss of venue and lack of support from automakers - "particularly Nissan and Tesla" - as hardships. The event was scheduled to take place August 9 through 17, with only battery electric vehicles invited to take part - no plug-in hybrids or range-extended vehicles. Williams said he'd only try a similar event in the future if sponsorship were provided up front. Read more at Green Car Reports. The Nissan Leaf will finally go on sale in Puerto Rico.
