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.

2013 Buick Encore

Ignored On Arrival, But Coming On Strong
An image exists out there that perfectly conveys the fate we thought would befall the Buick Encore after its world debut at the 2012 Detroit Auto Show. The shot shows the just-unveiled Encore on stage, basking in the glow of spotlights but surrounded by a large display area that's bereft of both cars and people. Two journalists are sitting on a couch over to the side, both facing the Encore but ignoring it as they inspect their swag, and a solitary custodial engineer pushes a vacuum back and forth across a sea of gray carpet.
Like a kid with his birthday cake at a party no one came to, this little crossover's debut was largely, almost cruelly, ignored. Who can blame us, though? Two shows ago, the Motor City's main stage welcomed the redesigned Aston Martin-esque Ford Fusion, the 3 Series-assassin ATS from Cadillac and the return of Dodge to the small car game with the Dart. A fourth model for the wayward Buick brand, especially one so arguably un-Buick in form and function, did not seem to deserve the attention paid to its peers that year.

How to hack a Buick Regal with CarKnow

If you own an Apple iPhone or Android device, perhaps you've been tempted to jailbreak or root it. This process gives you access to the the software's code, and can be used to make minor or drastic changes to its operating system. CarKnow, a company in Boston, is working applying a similar concept to the automobile.
Translogic recently took a look inside CarKnow to see just how it can tweak the computers inside a car and what sort of things can be done. As our transportation tech sister site explains, CarKnow basically created a digital duplicate of their Buick Regal in the cloud, while harvesting data generated to create custom apps and infiltrate the deepest function of their test car.
And before you freak out about people maliciously taking over your car, CarKnow's founder, Josh Siegel, stresses that it isn't quite so easy as driving up alongside someone. Take a look at the full video below to see just what it's like to jailbreak a car.
