China's Buick Envista crossover is coming to the United States

Confirming an earlier rumor, Buick has announced that the Envista crossover it unveiled in China earlier in 2022 will travel across the Pacific and land in American showrooms. The fastback-like soft-roader's main mission will be to lure younger buyers into the firm's showrooms. "[The Buick Envista is] already in production in China, off the design of the Buick Wildcat. Getting ready for the United States here as well; just a beautiful addition to the Buick line-up," said General Motors president Mark Reuss during a conference call in November 2022. His announcement asks more questions than it answers. We don't know when the Envista will make its American debut, whether it will be imported from China or built elsewhere, or precisely where it will slot in the Buick range. Enthusiast website GM Authority speculates that we could see the model in time for the 2024 model year and that the lineup will include an upmarket trim level with the Avenir designation. Technical details will be released closer to the Envista's on-sale date. For context, the version sold in China carries a base price of RMB 150,000, which represents about $21,000 at the current conversion rate, and ships with a turbocharged, 1.5-liter four-cylinder engine rated at 181 horsepower and bolted to a continuously variable transmission (CVT). It's available with a pair of 10.25-inch displays (one for the instrument cluster and one for the infotainment system), a surround-sound system, and a sporty-looking appearance package named GS (that should raise some eyebrows from the long-time Buick fans out there). Convincing young motorists to put the Buick brand near the top of their shopping list will be just one of the Envista's tasks. On a secondary level, it also previews the design language that will permeate the rest of the range (including a series of EVs) in the coming years.

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.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
