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?

2021 Buick Envision fuel economy revealed

Despite being revealed a few months ago, the 2021 Buick Envision has been lacking in in-depth details. But thanks to the EPA, we have a bit more information on the luxury crossover, specifically fuel economy. And it seems the new model is significantly more efficient than its predecessor. The only powertrain combination we have numbers for at the moment is the turbocharged engine with all-wheel drive. The Envision is expected to have a front-wheel-drive version, too, though an example with the old model's naturally aspirated four-cylinder is probably long gone. As for the turbo, all-wheel-drive Envision, it will get 22 mpg in the city, 29 on the highway, and 25 combined. That's the exact same as the old naturally aspirated, front-drive Envision, and it's an improvement of 2 mpg in town, 4 on the highway and 3 in combined driving over the previous turbo, all-wheel-drive version. As an extra bonus, the EPA notes that the new turbo Envision runs on regular gasoline, rather than premium like the old Envision. So not only will it use less gas, what it uses costs less. We're expecting the new Envision to go on sale early next year. While we know that the Envision will have a turbocharged engine, and the naturally aspirated one is probably discontinued, we don't know which engine it is. It could be an updated version of the old engine, which made 252 horsepower and 295 pound-feet of torque, or it could be the engine from the Cadillac XT4, which makes 230 horsepower and 258 pound-feet of torque. The latter seems more likely, since the XT4 gets similar fuel economy. A nine-speed automatic and front-wheel drive or all-wheel drive are also planned for the crossover. Related Video:

Despite strong profits, GM still fighting flat market share

Looking at the progress General Motors has made since it entered bankruptcy, it's easy to forget that the company still has a long way to go before it's the juggernaut it once was. A recent report from Reuters points out that, while GM is making money, it isn't making any gains in terms of US market share. Quite the opposite, really. Consider this factoid: In 1963, nearly half of the cars sold in the United States were from Chevrolet, Cadillac, Buick, GMC or Pontiac. Now, the company's US market share is stagnant at 17.9 percent. That same number is half of just Chevy's 1963 market share. This is all despite GM going on a binge replacing or updating its models. "Market share increases are not instantaneous," Mark Reuss told Reuters at the 2014 Detroit Auto Show. "We've got a lot of baggage. Don't underestimate what people though of us, or these brands, through these hardships and 30 years." The reasons for the stagnant market share are numerous. Reuters points out that retooling of factories and a focus on limiting incentives are both good things for profit, but not necessarily for market share. There's also the troubling turnover of the brand's marketing department. These issues don't change the fact that Chevrolet has lost 1.4 percent of its market share in two years, and that Cadillac - arguably GM's most improved brand overall - has lost 1.2 percent in the same period. Part of that can be blamed on GM's avoidance of fleet sales in favor of more profitable customer sales. "Our focus has really been on retail and that's where we've got the growth," said Alan Batey, GM's interim global marketing boss. "We want to grow GM and that means growing market share and profits, but it's not at all costs," Reuss said.
