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 Envision interior just as nice as its exterior

GM China loosed more photos of the all-new 2021 Buick Envision, this time of the interior. We are happy to report that the cabin design is just as pleasing to the eye as the exterior. When the 2021 model shows up for the reunion with its earlier model-year siblings, no one will recognize it. The modestly dated interior of the current crossover with its too-small infotainment screen and Rorschach-blot button placement is all gone. The gaudy curves and textures on the current instrument panel give way to a simple, split-level, bi-color form. What's more, the IP subtly carves out distinct driver and passenger spaces, a design trait normally reserved for sports cars. When Buick and GMC design boss Helen Emsley said the coming Envision would possess "striking styling designed to combine the expressiveness of a car with the practicality of an SUV,” she wasn't lying. The new steering wheel picks up more substantial spokes decorated with linear buttons instead of the circular pads, and its center cap is wider and no longer reminiscent of an alien face. The dash's dark portion up top houses a 10-inch infotainment screen canted at an 18-degree angle for the driver's ease-of-use. Air vents accentuate the break between the top and bottom of the instrument panel. Beneath the center vents, in the cabin-colored portion of the dash, are a slick set of climate controls. The pushbutton gear selectors along the left side of the center tunnel come from the China-market Enclave. And even the cupholders are handsome. The Envision Avenir gets a few exterior changes like a mesh grille and nicer wheels to set itself apart, the interior wearing Ivory White and Jazz Black hues and diamond-stitched seats. We might prefer the interior with peanut-butter brown and black even more. And suddenly, the Cadillac XT4 could have a problem; the Buick and the Cadillac share the E2 platform, but one of them — in photos, at least — is incontestably more fetching. As for tech, expect Android Auto and Apple CarPlay standard, and driver safety features such as automatic emergency braking with pedestrian detection, lane-keep assist, and the automaker's safety alert seat. Regular conveniences will include space for five, nearly two dozen storage cubbies, and an available giant panoramic moonroof. The only engine we've heard tell of so far is a 2.0-liter turbocharged unit, expected to be a carryover mill with 252 horsepower and 295 pound-feet of torque.

Cadillac Celestiq, Lyriq, Hummer, other future GM electric cars: Here's everything we saw at ‘EV Day’

WARREN, Mich. — Today, General Motors held an “EV Day” event at its Warren, Michigan, campus to present its new “Ultium” battery technology, modular electric vehicle architecture and soon-to-come electric vehicles. Unfortunately, we were forbidden from bringing cameras into the event, so while we canÂ’t show you what we saw, we can tell you more about it. While we saw the previously teased Cadillac EV (which we now know to be called the Lyriq) and the GMC Hummer pickup teased during the Super Bowl, there were a number of other future cars at the event, which GM President Mark Reuss assured us are all real vehicles in the works. The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built “very locally.” It had been hiding under a dark sheet all morning, with the front and rear illuminated Cadillac emblems shining from underneath. When the wraps came off, we saw a long, white, four-seat fastback sedan. The 23-inch wheels were pushed out to the very corners of the car, giving it what appeared to be a very long wheelbase. The model on the stage had no side mirrors or visible door handles. The grille mirrored that of the Lyriq crossover next to it, with integrated lighting in lieu of the usual mesh or slats youÂ’d see in an internal combustion car. The entire roof, all the way until it tapered to the tail of the vehicle, was tinted glass. In back, vertical tail lighting ran down the C-pillar before turning rearward across the top of the trunk. Inside, everything below the beltline of the windows — essentially all but the headrests and top portion of the steering wheel, was hidden from view. Behind the Celestiq, a large digital display showed a rendering of its interior. The dash consists of a pillar-to-pillar curved LED display serving as both instrument panel and infotainment system. Protruding forward between the front seats was another touchscreen that appeared to house some more controls, with open area, probably for storage, below it. The rear seats had the same sort of touchscreen between them. Built into the back of the front seats were a pair of rear-seat entertainment screens, much like we saw in the Lyriq. The door panels blended wood, metal and animated lighting to give character and a sense of opulence. GM interior design manager Tristan Murphy was on hand to tell us a bit more about the Celestiq.
