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?

2019 Buick Regal to get Avenir luxury treatment

Buick will make the 2019 Regal sedan available in its top-tier Avenir trim, the fourth Buick model to carry the sub-brand name after the Enclave, LaCrosse and the GL8 in China. Buick says the Avenir line is selling faster than other trim levels on both the Enclave and the LaCrosse, and that half of all Regal Sportback buyers are opting for the top trim level, reflecting buyers' demand for more premium midsize cars. "Avenir sales have exceeded our expectations," Phil Brook, vice president of Buick and GMC Marketing, said in a statement. "Buick customers value the exclusive styling, premium features and convenient experience Avenir provides, and we are excited to extend that successful formula to Regal." So what's the Regal Avenir all about? Well, Buick will debut its first cloud-connected infotainment system, bringing embedded apps and enabling owners to set up their own profiles and user preferences for use in things like available navigation and voice-recognition, and carry over that profile to other compatible vehicles. The Avenir will come standard with safety and driver-assist technologies such as rear park assist, rear cross traffic alert, lane-change alert with side blind zone alert, LED headlights with auto leveling, cornering lamps and driver-side auto-dimming mirrors. Advanced adaptive cruise control and other active safety technologies are also available. Inside, there's a "Whisper Beige" theme with ebony accents, diamond quilt-stitched front seats, embroidered first-row headrests and sill plates carrying the Avenir script. An ebony theme is also available. The exterior gets a more dramatic look, with the Avenir 3-D mesh upper grille, script badging on the front doors and 19-inch Pearl Nickel wheels. Under the hood is the Regal's standard 250-horsepower 2.0-liter four-cylinder making 260 pound-feet of torque and mated to a nine-speed automatic. Avenir was the name of a four-door concept Buick unveiled as a surprise in 2015 in Detroit. The next year the company announced it would use the name as a top-tier trim level starting with 2018 Buicks. Pricing for the 2019 Buick Regal Avenir will be announced when it arrives at dealers.

Buick teases electric concept crossover for China

Buick released a teaser image of a new all- electric concept SUV it's calling the Enspire. It'll bow at Buick Brand Night on April 17 in Wuzhen, Zhejiang, and be on display to the public at the Beijing auto show later in the month. Buick says only that the Enspire "leverages GM's global resources and is an exploration of design and new technologies. It is the brand's latest example of innovation and application of future electric smart mobility." The darkened, right rear three-quarter shot shows a rounded rear fascia, a narrow tail lamp that stretches the length of the tailgate and a third brake light on the roof spoiler. While this concept is clearly aimed at China, GM Authority notes that General Motors previously filed to trademark the "Enspire" name in the U.S. in 2015. GM CEO Mary Barra outlined the company's electrification plans for investors in November and included a slide of an unbadged crossover under the title "Leveraging existing BEV platform to expand in near term," which some are speculating could be this Enspire concept. It also suggests that Buick could be developing a vehicle based on the Chevrolet Bolt platform. GM plans to l aunch 20 new EVs by 2023, targeting 1 million electric-vehicle sales by 2026. Buick is GM's best-selling brand in China, comprising about 1.2 million vehicles sold in 2017. Buick last year showed off the Velite 5, an extended-range hybrid based on the Chevrolet Volt, as a production car for China. Related Video:
