China-market Buick Envista rumored possible replacement for the Encore

Buick currently sells four crossovers, the Encore, Encore GX, Envision, and Enclave. That number will soon be whittled to three, the Encore expected to end production after this model year. If speculation provided by GM Authority is correct, there could be changes afoot in the middle of the line in time for the 2024 model year. Buick has said it will maintain four ICE-powered crossovers, so the brand will need something to fill the coming gap. GMA sources suggest the China-market Buick Envista could get the nod. Buick launched the coupe-esque model across the Pacific in August, a relation to the Chevrolet Seeker that appeared on the Chinese market in April. The Envista debuted the brand's latest design language inspired by pure-electric concepts like the Electra-X and WIldcat. Thin, angled headlights frame a wide, low grille, leading back to a roof that slopes into a high back and double spoilers. GM applied to trademark the Envista name in the U.S. in early 2019, then maintained it with extension requests until earlier this year. Then, in September 2022, the automaker abandoned the application, which could bode ill for whatever chance there was, if any. Another snag could be that the Envista is 182.5 inches long, 71.5 inches wide, and 61.6 inches high on a 106.3-inch wheelbase. Various reports have pitched the Envista to fill the (small) space between the Encore GX and the Envision; however, the Envista falls just 0.10 short of the Envision's length, and it's three inches smaller in every other dimension. On the other hand, the Envista is 11.1 inches longer and 0.1 inch wider than the Encore GX, with a wheelbase 4.1 inches longer. That makes a lot of overlap in the dimensional Venn diagram. Were the Envista to come as-is, it wouldn't so much be a replacement for the Encore as be a different kind of compact SUV from the Envision on a more modern platform. Further speculation from "sources familiar with the matter" says a U.S.-market Envista could get the Avenir treatment. Avenir marks the ultimate in Buick luxury, an appellation currently restricted to the Envision and Enclave. According to a separate report, the Encore GX is also headed into the Avenir club with the compact crossover gets refreshed for the 2024 model year. An Encore GX Avenir would adopt some exterior tweaks like 18-inch alloys, and turn a load of optional equipment available for the Encore GX Essence trim into standard equipment. Related video:

2018 Buick LaCrosse gets a mild hybrid model, lower price

Update: Buick provided us with horsepower and fuel economy figures. The text has been updated to reflect this. Buick is rolling out a variety of updates for the 2018 LaCrosse, including a new mild eAssist hybrid. Like the previous generation LaCrosse and Regal eAssist models, this one features a small electric motor and an equally small battery pack that together augment rather than supplant the gasoline engine. The motor, attached to a 2.5-liter four-cylinder engine, helps to make takeoffs smoother and provide additional torque on demand. The gasoline engine still does the majority of the work, though. Combined, the powertrain produces 194 horsepower and 187 pound-feet of torque. It will also allow the LaCrosse to get 25 mpg in the city, and 35 mpg on the highway. While the electric powertrain doesn't provide primary propulsion, it does come with other benefits. The small battery means the LaCrosse maintains a folding rear seat. The battery also provides power to accessories when the engine shuts off at a standstill. This mild hybrid powertrain will be the standard engine for all 2018 LaCrosses, and they come with a lower base price. The 2018 model will start at $31,415, which is about $1,500 less than the lowest priced 2017 V6 LaCrosse. The V6 will still be available as an option, and Buick has updated it, too. The 2018 V6 models will also all come with a new 9-speed automatic transmission. The new LaCrosses will go on sale this fall. Related Video: Image Credit: Buick Green Buick Hybrid Luxury Sedan

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.
