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 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.

Buick Electra-L, Electra-LT concepts lead the Wildcat to production

Buick loves the Beijing Motor Show, and why shouldn't it? Working with its local partner, SAIC, the brand seems to saves up so much mojo for April in Asia and shows up with stunning designs. Here are another two takes on the brand's latest sheet metal philosophy, penned by the SAIC-GM Pan Asia Technical Automotive Center and riding on GM's Ulitum platform, the Electra-L sedan and Electra-LT wagon concepts. The Electra-L could be seen as a production version of the Wildcat EV concept from 2022 (not the Wildcat from 1985) that launched Buick's new design language. All the major forms and curves are there, so too the turbine-style wheels, but the fastback roof's been stretched to create adequate headroom for a quartet. The edges of the front fascia have been redrawn to be less aggressive and form a canvas for illuminated ornamentation. The four-door stretches 198.3 inches long on a 118.1-inch wheelbase, meaning less than an inch difference in both dimensions between the Buick and the new BMW i5. Power comes from a single motor on the rear axle making 342 horsepower. A battery of unknown capacity is claimed to be good for a 435-mile range under China's CLTC test loop. The light-sensing glass roof hovers over a rectilinear instrument panel with a floating main display and a retractable 7-inch screen for the front passenger, four pressure-sensitive "zero-gravity" seats wrapped in an eco-friendly fabric, and rear quarters with a small inductive cooktop for enjoying tea in the custom tea set.  SAIC and Buick had less to say about the Electra-LT. Looking like the Allroad version of the Electra-L, it's got fender extensions framing the "titanium metal armor" wheel design, an air suspension that can lift the body by 1.6 inches, and that roof box to broadcast its light adventure credentials. Fitted with the same basic interior layout as the sedan, the wagon might add a third row; the description says its "eConnect smart cabin system supports 7-screen interaction." We're not sure if something got left out of the powertrain description, though, as the Electra-LT said to be powered by a 342-hp motor on the rear axle while also possessing "independent four-wheel drive."    Two years ago, Buick said it would introduce five all-new EVs in China by 2025. The sedan is rumored to be headed to the Chinese market next year, a production version perhaps ready by the time of the 2025 Auto Shanghai.
