It looks like Buick is working on a new Regal GS

When Buick revealed its Regal-badged version of the Opel Insignia/Holden Commodore sedan and wagon, it left out one significant model, the GS. The high-performance Regal was missing in action, but these new spy photos seem to indicate one is coming soon. It looks like it will be pretty subtle on the outside. Upon close examination, we can see that each side of the front bumper features a much larger grille than the normal Regal Sportback and TourX. The thick upper borders on the grilles also look like good places for some LED accent or fog lights. These larger grilles appear to be the only significant difference to the front, though. On the sides, there are slightly deeper side skirts than those on a standard Sportback, and the rear bumper looks to be lifted from the TourX, but without the wagon's aluminum cladding. One other indication that this is a high-performance Regal is the car's front braking equipment. We can make out a Cadillac logo on the front brake calipers, which shows that this isn't running standard Regal stoppers. As for what's under the hood, it's tough to say, but we don't think it will use a turbocharged four-cylinder as the previous generation did. Instead, we think it may be using a V6. That's a hard maybe. The base Regal's turbo four makes as much power as the old GS, and although Buick could crank up the boost for more power, it could also make use of the V6 it will offer overseas. In the mechanically identical Commodore, a 308-horsepower V6 will be available along with a 9-speed automatic and the same type of all-wheel-drive system as the Ford Focus RS. This option would make the upcoming GS more powerful than the old one, and the new standard model, plus offer all-wheel drive. We would like to see even more power than 308, since the top-dog previous-generation Insignia OPC had a 325-horsepower V6.

1969 Chevrolet Chevelle vs 1987 Buick GNX in Generation Gap showdown

Generation Gap generally tries to adhere to a theme for each episode, and for the final video from the Lingenfelter collection, the series might have its best idea yet - limited-production muscle cars from General Motors.
On one side you get a 1969 Chevrolet Chevelle COPO, and it's an absolute sleeper. Other than the SS wheels, this classic coupe looks practically bone stock, at least until the engine fires up. Under the hood is a 427-cubic-inch (7.0-liter) V8 making a claimed 425 horsepower and 460 pound-feet of torque. This was the sole year for the COPO package on the Chevelle, and Chevy only made about 323 of them.
The Chevelle's challenger is almost as rare and arguably just as cool. The 1987 Buick Grand National GNX looks just as mean today as when new. It eschews a traditional muscular V8 in favor of a 3.8-liter turbo V6 making a claimed 276 hp and 360 lb-ft, although that number is supposedly a bit underrated. Also, just 547 examples of the GNX version were ever built making it quite a collector's item too.

Question of the Day: Coolest factory-supercharged car?

Last week, we discussed possible engine-swap recipients for the plentiful-in-every-junkyard Eaton-supercharged GM 3800 V6 engine. The Buicks, Oldsmobiles, and Pontiacs that came with that engine from the factory were reasonably cool, of course, but when you look at all the production cars that have been available with supercharging over the decades you can find some pretty amazing stuff. My personal favorite has to be the Paxton-blown Studebaker Larks of the early 1960s, partly because the Lark was just about the stodgiest-looking, sleepiest little sedan available in America, possibly the most ridiculous recipient of a howling force-fed V8 imaginable, and partly because of the name of the optional supercharged 289-cubic-inch V8 you could get in the Lark: Jet-Thrust! What do you say is the coolest factory-supercharged car of all time? Related Video: Auto News Buick Automotive History Performance Classics supercharger questions
