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.

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.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
