GM claims it's first to sell million 30+ mpg vehicles

As we continue to put together all the data for the year-end edition of By The Numbers, General Motors has announced that it sold more than a million vehicles in the US last year that achieved at least 30 miles per gallon on the highway. More impressively, GM managed this feat using multiple strategies including small vehicle size, turbocharged engines and hybrid or plug-in technologies across four brands (Buick, Cadillac, Chevrolet and GMC) accounting for 13 separate models. This number will grow even more in 2013 thanks to cars like the all-electric Spark, the diesel Cruze, the range-extended Cadillac ELR and the Buick Encore compact CUV.
GM's small car sales were up 39 percent last year helping to attain this million-sales mark for 30-mpg models, and almost 40 percent of all GM sales consisted of cars with fuel-efficient I4 engines. In regards to more advanced means of improving fuel economy, GM says that it plans on having 500,000 vehicles with "some form of electrification" on the road by 2017.
Scroll down for the full list of GM's million 30+ mpg cars as well as an informative press release.

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.

NC dealer falsely announces return of Regal Grand National, Regal GNX

Like many new car dealers, Liberty Buick GMC gets so excited about its brands' new wares that it puts out press releases announcing when new models are on the way. That's not typically national news, but the Charlotte, NC store has created a bit of internet hubbub by announcing that it will be "one of the first dealers in the country to offer the Buick Regal GNX," and it's even started to add customers names to a waitlist. Only one problem: Despite seemingly annual rumors and calls for such a model, Buick hasn't announced any Grand National models at all – let alone a GNX – and no such models are actually in the cards. The Liberty Buick press release talks in a nostalgic, venerative tone of the original 1982-1987 GN franchise, and goes on to say: "These returning relics will be based on the highly-acclaimed Alpha vehicle architecture currently used in the Cadillac ATS, 2014 Cadillac CTS, and soon to be in the sixth-generation Chevy Camaro. Alpha is the internal name of a General Motors vehicle architecture engineered to underpin compact and mid-size rear-wheel-drive vehicles." In the release, Liberty Buick claimed the GN/GNX models would arrive in late 2015, citing a coupe bodystyle, including a rather fantastical-looking GNX rendering from Bestride.com. Unsurprisingly, none of this is true. Autoblog reached out to Buick for comment about the release, and brand communications manager Nick Richards confirmed that the company had discussed the matter with Liberty Buick representatives. Richards went on to say that the release was wholly incorrect, proclaiming "an agency [for the dealer] picked up a lot of stuff off the internet" and ran with it, including an old Car and Driver story from 2013. The dealership subsequently issued a retraction, with Scott McCorkle, owner of Liberty Buick GMC saying: "We love the idea of the Buick Regal GNX coming back to our showroom but for now, it's only a concept. Bottom-line, the article was incorrect.
