Buick version of Equinox/Terrain CUV spied testing... with autonomous gear?

Let's get the most pressing bits of this story out of the way right off the bat: What we see here appears to be a new compact crossover from Buick. According to the spy photographer, this machine may be a little bit smaller on the outside than the current Chevrolet Equinox and GMC Terrain 'utes, which makes sense since recent rumors suggest GM's small crossovers will migrate to a new platform that will mark a convergence between the automaker's Delta (Chevy Cruze, Buick Verano) and Theta (Equinox, Terrain) platforms. This Buick would likely use this new D2UX platform.
We've been expecting Buick to unleash a crossover to slot between the very small Encore and the very large Enclave, and various rumors have indicated that the model may be known as either the Anthem or Envision. It's worth mentioning that Buick had planned, back in 2009, to release a vehicle in the compact CUV market, but abandoned those plans after a particularly poor reception.
And now for something completely different... Take another look at the spy shots above, and pay special attention to the cylindrical device mounted to the vehicle's roof. We can't say for sure what it is, but our spy photographer opines that it looks quite a bit like the 360-degree Lidar camera equipment used by Google for its autonomous cars. Is General Motors working with Google on autonomous car technology? We don't know, but you can definitely consider us intrigued.

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.

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.
