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.

BMW takes 30th Anniversary Edition M5 out to drift

If you only look at the videos from BMW, it appears that the best way to celebrate the 30th birthday of the M5 is some smoky drifting, and it sure looks like a great way to mark the occasion to us. Now that the Bavarian brand's new 30th anniversary special edition is all set to hit the road, the most powerful M5 ever is getting it own chance to roast its tires on video, as well.
The M5 30th Anniversary Edition shouldn't have any problem hanging its rear end out, really. Under the hood, its twin-turbocharged 4.4-liter V8 is turned up to 600 horsepower and 516 pound-feet of torque and can allegedly sprint to 60 miles per hour in a scant 3.7 seconds. That's pretty impressive for any sports car but especially for a sedan that can still carry four passengers comfortably cosseted in leather and Alcantara upholstery.
BMW is making just 300 of these celebratory models worldwide, and appropriately for the anniversary, only 30 of them are going to be available in the US. If the special M5 doesn't make your heart race, the video basks in a little nostalgia, as well, by showing off the original model for some historical context.

2017 BMW i3 rumored to get more electric range

BMW will reportedly give the 2017 i3 a jolt of extra range that will increase the EV's max driving distance to around 120 miles. If true, that would be quite a boost from the current EPA-estimated 81 miles. An upgraded lithium-ion battery will make this improvement possible, according to Automotive News. Ian Robertson, BMW's boss for sales and marketing, told AN the upgrade to the i3 "puts it into a much more usable range." The company has more tweaks in store for the 2017 model but doesn't want to discuss details about them yet. Rumors late last year hinted that the extra range for the i3 would come thanks to a higher-density battery, improved electronics, and new software. The changes could push range to over 124 miles on the European testing cycle. BMW would also offer the improvements on the i3 REx range-extended model, and the company would even allegedly allow current owners to purchase the upgrades. The German automaker wants to offer these updates every three years to keep the EV fresh. If BMW can achieve 120 miles of range, then the electric i3's driving distance would come significantly closer to the current REx's EPA-estimated 150 miles. Of course, the range-extended model can always be topped up with a tank of gas to keep its wheels spinning further. The i3's rumored boost would also still put it short of the roughly 200 miles that Chevrolet promises from the Bolt when that model arrives late this year. In any case, it's an exciting time for proponents of electric cars. Related Video:
