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 offers M Performance Power Kit for 2012 335i sedan

BMW has let loose a new M Performance Power Kit for its F30-generation 335i and 335i xDrive sedans. Starting at $1,100 for the kit - installation is extra - your car will be fitted with a new ECU and air intake on the functional side and an M Performance engine cover and rocker panel stickers on the decorative side. The Power Kit raises the 3.0-liter inline six-cylinder's horsepower rating from 300 to 320, and on automatic models, torque gets a boost from 300 pound-feet to 332 lb-ft - manual transmission models get a smaller bump to 317 lb-ft.
According to the Bavarian automaker, you'll be able to hear the change in the overrun exhaust note, and 0-60 mile-per-hour times drop by 0.2 seconds. The package is available now at all BMW Centers in the US, and if you get it installed when you purchase the car new, it will get the same four-year, 50,000-mile warranty as the vehicle. Have it done after the fact and the kit will be warranted for two years and unlimited miles. There's a press release below with some more details.

Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.
