Opel Insignia OPC Sports Tourer shows its fresh face ahead of Frankfurt debut

Drive down the Autobahn and there's any number of vehicles likely to pass you, and most of them are produced locally. But if you're wondering how that Opel left you in its dust, look closely (and quickly) enough and you might make out the letters OPC on the back.
They stand for Opel Performance Center (the German counterpart to Vauxhall's VXR line) and they adorn performance versions of the Corsa, Astra and Insignia. The latter is undergoing a bit of a refresh and is expected to debut at the Frankfurt Motor Show in a couple of weeks, but you don't have to wait that long as our intrepid spy photographers have caught it in the flesh outside an Opel facility in Germany.
Spied here completely undisguised in Sports Tourer (read: wagon) form, the Insignia has had a few nips and tucks performed, but we'll be more intrigued to see what it's got under the hood. The current model packs a 2.8-liter twin-turbo V6 driving 325 horsepower to all four wheels, but rumors suggest that the OPC (yeah you know me!) could have as much as 400 hp up its sleeve. That would make this one heck of a sleeper - especially in wagon form - and only make us pine for a more potent version of its twin Buick Regal to roam our highways, too.

Buick dusting off Grand National, GNX and T-Type nameplates

Inside Line reports Buick is planning to bring back some of the more storied names from the company's past, including the Grand National, GNX and the T-Type. Those cars rose to prominence in the 1970s and '80s to become performance legends of their day.
The new models will reportedly make use of the rear-wheel drive platform that currently underpins the Cadillac ATS and all would arrive as sedans - according to an unnamed source familiar with the initiative. Odds are the T-Type and the Grand National would share a driveline, with honest money being on a new twin-turbocharged 3.6-liter V6 as the engine of choice. Word has it the mill will be good for anywhere from 350 to 400 horsepower.
That leaves only the GNX. Inside Line seems to think that machine could get down the road with some help from the all-new GM LT1 small-block V8. The engineers behind the ATS platform have already told us the engine bay is large enough for to accommodate the big eight pot, and since GM is most certainly working on an ATS-V, a slightly less powerful, less luxurious Buick iteration makes some kind of sense. We can't wait to see these things in the light of day.

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.
