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?

Buick Avista concept is 'buildable', but not a priority

Buick could build the striking Avista concept that debuted at the Detroit Auto Show, though it's not a top priority, the brand's top executive said Tuesday in New York. "The reaction's been so great, we'll try to run the numbers and see if there's a business case," said Duncan Aldred, Buick vice president of sales, service, and marketing. Buick will show the Avista in red this week at the New York Auto Show as a followup to its Detroit debut. Buick actually built two prototypes, which are being used to promote the brand's performance potential at auto shows around the world this year. "It's very buildable," Aldred told reporters after the reveal of the reveal of the 2017 Encore small crossover before the New York Auto Show. "Ultimately, it comes down to priorities." He added, "We'd love to do it. We could do it, but [there's] lots of things we'd love to do... Nothing to confirm or deny." The Avista concept suggests a sports car with a twin-turbo V6 with 400 horsepower put to the rear wheels. The two-door followed another impressive Buick concept, the Avenir, which was four-door styling exercise from the 2015 Detroit show. Though the Avista remains on the minds of enthusiasts – helped in part by Buick – the priorities for the brand are crossovers. The Avista offers style, but the freshened Encore is the substance for Buick in New York, which along with the Envision, launches this year into the red-hot utility segment. The new Cascada convertible and redesigned LaCrosse also are joining Buick's lineup this year. While the Avista is doable, the brand clearly has other priorities ahead of it. Related Video:

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.
