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?

GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:

Buick Envision Plus is a seven-seater tweener developed for China

Buick has filled the gap separating the Envision and the Enclave with a new crossover named Envision Plus. Launched at the Shanghai auto show, the three-row people-mover is scheduled to go on sale in China later in 2021. The plus-sized Envision stretches 190.7 inches long, 74.1 inches wide, and 66.7 inches tall, figures that make it around eight inches longer and two inches taller than the regular Envision. It's also a full 14 inches shorter, four inches narrower, and three inches lower than the Enclave, which is the biggest crossover in the Buick range. Designers didn't settle for stretching the Envision's wheelbase. They gave the Plus a more upright front end characterized by a taller grille, a flatter and longer roofline, and a redesigned rear end accented by a strip of bright trim that connects the lights. Only photos of the upscale Avenir trim (shown above) have been published so far. Images of the cabin are not available yet. We expect the Plus offers an interior close to the standard Envision's — from the driver's point of view, at least. The biggest difference is that the longer Envision lives up to its name by letting motorists take more gear or kids along for the ride thanks to a more spacious trunk and third-row seats. Power for the Envision Plus comes from a turbocharged, 2.0-liter EcoTec four-cylinder engine fitted with 48-volt mild-hybrid technology. Bolted to a nine-speed automatic transmission, the turbo-four is the same basic engine found in the American-spec Envision, where it develops 228 horsepower and 258 pound-feet of torque, but figures for the Plus weren't released. Front- and all-wheel-drive models will presumably be available. Buick will release pricing information closer to the model's on-sale date. As of writing, the Envision Plus has only been announced for China, where it will be built, but unverified reports claim it will arrive in American showrooms before the end of 2021. We've reached out to the company, and we'll update this story if we learn more. 2021 Buick Verano Pro GS View 5 Photos What else did Buick show in Shanghai? Buick no longer sells sedans in America, but it remains present in that segment on the Chinese market. In addition to the Envision Plus, it unveiled a model named Verano Pro developed specifically for China, built locally, and aimed at relatively young buyers. At launch, motorists will be asked to choose between the regular sedan and a sportier-looking variant that wears the storied GS emblem.
