2020 Buick LaCrosse images leaked on Chinese website

Buick is planning a refreshed version of its LaCrosse full-size sedan for the Chinese market, judging by these photos discovered by the site Auto Verdict on a Chinese government site used to certify upcoming new models. We can only see exterior cosmetic changes, but they bring the LaCrosse more in line with the styling of the new Regal and Enclave models, leading to speculation that it won't be long until the changes show up in the U.S. The front three-quarters photo shows off a redesigned front fascia, with slimmed-down headlights that are now tied to the grille instead of set apart by body-color surround, thanks to some new chrome treatment. There's also a chrome wing on the grille, similar to what's seen on the 2019 Enclave and new Regal. The lower front fascia is also different, with new L-shaped fog lamps. On the rear, there's a new chrome wing connecting and intersecting the taillights and surrounding the badge. There's no word about any interior changes, but they'd likely be minor in keeping with the exterior updates. Buick most recently debuted a 2019 LaCrosse Sport Touring version, while a mild hybrid model arrived for 2018. China, of course, has become Buick's largest market, but the picture is less rosy stateside amid dimming prospects for sedans, as consumers flock to crossovers and SUVs. In the third quarter, U.S. sales of the LaCrosse fell 31.1 percent from the prior-year period. Between January and the end of September, GM had sold 13,409, which was a decline of 14.2 percent. Its full-year 2017 sales totaled 20,161, which was down almost 27 percent from 2016. For perspective, Buick sold more than twice that number — 42,035 — as recently as 2015. The current generation launched in 2017. Related Video: Featured Gallery 2020 Buick LaCrosse China Image Credit: Buick Design/Style Buick Luxury Sedan

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

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.
