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.

Popular Mechanics Breakthrough Awards honors GM Super Cruise, BMW i3

Our friends at Popular Mechanics have announced the winners of their 2013 Breakthrough Awards, which honor innovations and new technologies in a variety of fields, ranging from medicine to electronics to space travel. Among the winners were a pair of automakers.
The BMW i3 was named one of PM's product breakthroughs, and while the diminutive city car has a range comparable to other electrics, Popular Mechanics was impressed the i3's use of carbon-fiber-reinforced plastic, which allows the i3 to tip the scales at just 2,800 pounds. But the i3's space-age materials wouldn't have been such a smash if it were priced beyond what the general public could afford. BMW's ability to offer a vehicle with such an advanced construction for around $42,000 (nearly half the price of the Cadillac ELR and only about $7,000 more than a Chevrolet Volt or Ford Focus Electric) is wildly impressive and speaks volumes about the future of ultra-light composites in the auto industry.
The other big winner comes from General Motors, which was named an Innovator this year for its semi-autonomous Super Cruise technology that's currently being tested on a Cadillac SRX. The technology, which we've reported on before, combines adaptive cruise control and lane centering into a super system that will allow hands-free driving under certain conditions.

2014 BMW 4 Series Coupe officially debuts, priced from $41,425*

Well, that didn't take long. Less than two hours after the first images of the 2014 BMW 4 Series Coupe leaked onto the Internet, we've been given the go-ahead to publish the whole kit and caboodle. And while we won't say we told you so, it looks as though the car's official details are standing true to our earlier predictions.
In other words, BMW will offer the 4 Series in 428i and 435i models, both of which can be had with xDrive all-wheel drive. Just like in the 3 Series, the 428i is powered by a 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and the 435i gets BMW's turbocharged 3.0-liter inline-six making 300 hp and 300 lb-ft. In three of the four models, both a six-speed manual and eight-speed automatic transmission are available; the 428i xDrive can only be had with the auto 'box. The 428i (with rear-wheel drive, we assume) can hit 60 miles per hour in 5.7 seconds (though BMW doesn't specify with which transmission), and the 435i will do that same sprint in 5.3 seconds with the manual and five seconds flat with the eight-speed auto.
We've already dissected the 4 Series' visuals, but the numbers show just how different it is from the 3 Series sedan. The 4 Coupe is one-tenth of an inch longer overall, while riding on the same 110.6-inch wheelbase, is 0.6 inches wider, and has a roofline that's a full 2.7 inches closer to the ground. It looks sleek, incorporating BMW's new design language from the 3 Series with an overall profile that's similar to the larger 6 Series coupe.
