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.

As US exports top 2 million, is America becoming the world's source of cheap cars?

North American auto production is booming with 2014 figures just shy of the of the 17.3-million vehicle record set in 2000. With more models being built on the continent, even more are being shipped overseas. Factories in the US exported 2.1 million cars last year – the highest number ever. About half of those went to Canada and Mexico, but more than ever have been heading to places like the Middle East and China. The upswing comes in part from from after-effects from the Great Recession, according to The Wall Street Journal. With a weak dollar and lower production costs after the financial crisis, building vehicles in the US was relatively cheaper and more competitive in the world. At the same time buyers around the world are going crazy for crossovers. According to the WSJ, BMW and Mercedes-Benz are already exporting the majority of their US production of these models overseas. Both automakers have also announced investments to expand production further here to send more vehicles abroad. Even Honda has been shipping more models out of the country than it imported here. There is a concern this international strength could start slowing because the dollar is strengthening against other currencies, though it's too early to know what the actual effect of this could be, according to the WSJ. "Of course, we closely watch currency exchange, but we don't make changes in production or allocation based on temporary fluctuations in the exchange rate," Ford North American boss Joe Hinrichs told the newspaper.

2015 Mercedes-Benz SLK250 Quick Spin [w/video]

We car writers tend to have a occupationally limited focus. Autoblog's stock in trade is automotive news and new car reviews, which often steers us towards forgetting existing models about 17 minutes after we've driven it a second time. You guys like reading about the new hotness, too, so it tends to work out. But the wonderful fact is that every car sold today will have a rich/interesting/heroic/tragic life for years to come. And, occasionally, even obsolete makes and models stay interesting. That was my thinking when this 2015 Mercedes-Benz SLK250 came into our fleet. Set to be replaced with the SLK300, with that car's 2.0-liter turbo'd engine, the 250 is already running out the clock in Mercedes dealerships. What's more, my test car came complete with – are you ready for this? – a six-speed manual transmission. I can't tell you the last exact model of Benz that I'd driven with a stick shift, but I can assure you that its engine was carbureted. Considering the odd spec and replacement timeline, my question, as I drove the SLK for a week: was this a unicorn destined to be a driver's dearest find? Driving Notes: Let me not bury the lede any more: the six-speed isn't a game changer for the SLK. Yeah, over the course of a few days I came to be comfortable with the slightly vague clutch and notchy shifter, but I didn't love it. I went blasting on a few back roads, and found the hand-shaker more involving to use than the standard auto, but it was long to throw and not overly precise when I moved up and down between second, third, and fourth. On the other hand, the old 1.8T under the SLK250's bonnet still felt well matched with the base SLK's boulevardier mission. Output of 201 horsepower and 229 pound-feet of torque doesn't give enough gumption to move the hardtop German lump with authority, but it was still enough to be quick off the line and offer easy highway passing. The turbo four didn't sound bad under full throttle, either, but it did rattle like old plumbing when idling in the driveway. Speaking of rattling: the adjustable and Airscarf-equipped seats did a lot of it. (Airscarf, you'll recall, is M-B's brand name for an in-seat fan that blows hot air on your neck; it's nice on a cold day.) Though comfortable and mildly bolstered, the driver's chair made all kinds of funny noises when I got in, got out, or cornered over 20 miles per hour. That's rough for a luxury car with 6,000 (or so) miles on it.
