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.

Buick Velite 6 to come in PHEV, electric versions for China

In addition to the all-electric Enspire crossover concept revealed this week ahead of the Beijing Auto Show, Buick is adding a new production variant to its Velite series of electrified vehicles for China. It's called the Velite 6, a plug-in hybrid that will launch this year in Buick's largest market. A full-electric version, shown in the lead photo above at right, is coming later. Buick already sells a vehicle called a Velite 5 in China, which is essentially a rebadged Chevrolet Volt, only with a higher electric-only driving range. This one is based on the Velite concept PHEV introduced in late 2016 at Auto Guangzhou. The PHEV and battery-electric versions look nearly identical, with a wide stance, plenty of creases and a hatchback design that bears some similarities to the longer 2018 Regal TourX wagon. The Velite 6 uses two AC permanent-magnet synchronous motors, a lithium-ion battery and a 1.5-liter four-cylinder combustion engine. Buick says combined gas-electric driving range is 435 miles, which is 15 miles greater than the Volt. Buick will assemble what it calls the "new-generation" ternary battery pack at its new SAIC-GM Power Battery Development Center in Shanghai. The company says the Velite 6 electric vehicle "will adopt a new-generation pure electric drive system to offer customers a smooth, quiet and natural driving experience." Both models get the cloud-based Buick eConnect technology, which allows over-the-air software updates, real-time integration with China's WeChat social media network, and other digital perks. Owners will also be able to use their smartphone as the vehicle's key, and they can also authorize others to use the car through their phones. China has long been Buick's largest market, with more than 1.18 million vehicles sold in 2017 compared to just 219,231 in the U.S., and the country has established aggressive mandates for production of electric vehicles. GM has plans to add 20 new electric and fuel-cell vehicles globally by 2023. Related Video:

2017 Buick LaCrosse First Drive

The 2017 Buick LaCrosse seems destined to never get the credit it deserves. It's bound to be dismissed as just another full-size sedan relic, ignored by those who habitually visit their Lexus dealer every few years for a new ES. This new LaCrosse will inevitably be overshadowed in the Buick showroom by SUVs and never fully appreciated by the majority of its buyers who simply want a big, comfy, and quiet car. That destiny would be a shame. The completely redesigned LaCrosse is now a legitimate luxury car, not because advertisements say it is, but for the way it drives, the way it looks, and the way it cossets you inside. The former is really the most impressive, since it's also the most surprising. During the LaCrosse press launch in Portland, Oregon, Buick boasted how comfortable and exceedingly quiet the car is, and indeed, it isolates road imperfections and allows for a pair of low talkers to converse in subdued tones. The big Buick sedan's low-effort steering will also satisfy the nice-and-easy tastes of most drivers. The best way to describe driving the LaCrosse is "unwaveringly pleasant." Yet, during that pleasant drive, road dips and mid-corner undulations don't make the comfort-tuned suspension bob and bound like its competitors might. Its body control and generally planted nature encourage speeds and confidence to creep ever so higher through successive sweeping corners on Oregon's densely forested Mist-Clatskanie Highway. Even that low-effort steering demonstrates precision, linearity, and just enough feedback to further spur on such a pace. This unexpected capability is best observed on cars equipped with the optional 20-inch wheels, which supplant the standard 18s and, more importantly, bring with them Continuous Damping Control (CDC) and GM's HiPer Strut front suspension, which is designed to quell torque steer and further improve cornering grip. You don't even have to engage CDC's firmer Sport mode to appreciate the LaCrosse's surprisingly sharp road manners. "We unleashed the engineers," chief engineer Jeffrey Yanssens said after our test drive. "I told them, 'I don't care how much it costs. I want you to know your system and I want your system to be the best it can be. What do you have to do to make that happen and what can I do to enable you to make that happen?'" Yanssens is honest and clearly proud of his team's work.
