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?

Opel Insignia OPC getting facelift. Will the Buick Regal GS see it, too?

We've seen spy shots of the base Opel Insignia wearing facelifted front and rear ends, and now it appears that the more potent OPC version will be benefitting from a nip/tuck, as well.
The front bumper has been redesigned, incorporating new air intakes - toned-down versions of the model's signature fangs - as well as a new grille. Out back, there will be minimal changes to the overall fascia, most likely stuff like slightly redesigned taillamps, and inside, these spy shots show a larger navigation/infotainment screen sitting atop the center console.
This is all well and good for the Insignia, but we're wondering how these changes will impact North America's Buick Regal GS. No, it may not share the same powertrain punch as the Euro-spec OPC, but visually, the cars are nearly identical. When questioned about possible changes for the GS, a Buick spokesperson told us that the automaker "can't comment" on any changes at this point. Even so, we wouldn't be surprised if some small changes come our way in the next year or so.

2021 Buick Encore sheds top two trims, offer only Base and Preferred

A few days ago, CarsDirect reported that the 2021 Buick Encore would prune its top two trims, the Sport Touring and Essence variants. Paring those two trims would leave the Base and the Preferred, creating larger price and amenities differences between the stalwart Encore and the new, larger, nicer Encore GX. It turns out the change has already gone into effect for the 2020 model year, as shown in Encore's Build & Price page at the brand's web site. Now the only trims available are the 1SV and Preferred. The prices for these trims won't change for next year, either. The Encore will start at $24,195 after a $995 destination charge, and now topping out at $26,215 for the all-wheel drive Preferred model. Previously, the Essence AWD established the top of the hill at $31,795. The move eliminates almost all of the MSRP overlap with the Encore GX, which ranges from $25,195 to $31,595. There will be less feature overlap, too. The now-dead Encore trims opened the door to proper luxury amenities like LED headlights, leather seats, dual-zone climate control, and an auto dimming rear-view mirror. The amenities available on the Preferred are limited to floor mats and accessories, save for the $495 Safety Package that adds Rear Cross Traffic Alert and Side Blind Zone Alert, and the $300 Remote Start. The Encore GX comes in three trims, Preferred, Select, and Essence, and "Leather-appointed seating" doesn't appear until the top-dollar Essence trim for $29,495 in FWD fettle.  The closest the Encore and Encore GX will get to one another is in engine output. The smaller crossover comes only with a 1.4-liter turbocharged four-cylinder that makes 138 horsepower and 148 pound-feet of torque. The Encore GX offers two engines depending on powertrain. A 1.2-liter turbocharged three-cylinder with 137 hp and 166 lb-ft comes solely with front-wheel drive, and a 1.3-liter turbocharged three-cylinder with 155 hp and 174 lb-ft is available with either front- or all-wheel drive.
