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.

How tariffs in China could cause a meltdown in the American South

While BMW is clearly a German company, the crossovers that are exceedingly important to it are actually made in Spartanburg, South Carolina. And more than that, the Spartanburg plant (physically located in the town of Greer) is where the corporate know-how and capability for those vehicles is concentrated. These are the vehicles – specifically, the BMW X3, X4, X5, X6, X7 – that drove record growth for the company in 2018, according to BMW. But whatÂ’s most notable about BMW Group Plant Spartanburg, given current events, is that according to the U.S. Department of Commerce it was the largest automotive exporter by value for the fifth year running in 2018. ThatÂ’s worth emphasizing: largest automotive exporter by value. Not GM. Not Ford. BMW. And where might one assume that more than a few of those X vehicles are shipped to? China. Some 360 miles southwest of Spartanburg is Mercedes-Benz U.S. International, Inc., in in Tuscaloosa County, Alabama. It started building vehicles in 1997. Since then, Daimler AG has invested in excess of $5.5 billion in the facility. It manufactures the crossover now known as the GLE, formerly the ML-Class. It also makes the GLE coupe and GLS. Daimler describes the Tuscaloosa facility as “the traditional home of SUV production” for those vehicles. When it reported its global 2018 sales, Daimler noted that on a global basis SUVs account “for more than a third of all Mercedes-Benz sales.” According to the Chinese finance ministry, on December 15th the Chinese government will impose a 25% tariff on automobiles (and a 5% tariff on auto parts) from the U.S. Certainly this is going to have a direct effect on the sales of vehicles that are manufactured in the U.S. and exported to China. BMW and Mercedes are going to take it on the chin for the vehicles that they make in plants that they invested in so heavily in the U.S. Which could potentially mean that people in places like Greer, South Carolina, and Vance, Alabama, are going to find themselves in the crosshairs of the combatants. Soo too could Lincoln, which produces vehicles in places like Louisville, Kentucky (Navigator), Chicago, Illinois (Aviator) and Flat Rock, Michigan (Continental). Although the Tesla Gigafactory 3 is rapidly nearing completion in Shanghai, it is worth noting that vehicles built in Fremont, California, are being sold in China in numbers that donÂ’t make Musk unhappy.

2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.
