Buick picks top 11 highlights from first 11 decades

Buick has taken the time to highlight some of the company's personal points of pride from the past 110 years. Those include everything from the automaker's very first vehicle, the 1904 Model B, to what Buick claims is the world's first concept car: The 1938 Y Job (above). That one also walked away with the worst name for a design study.
All told, the automaker has sold 43 million vehicles through the end of last year, and those include the lusty 1963 Riviera. That model celebrates its 50th anniversary in 2013, and remains one of the brand's most iconic designs.
Of course, Buick is rightfully proud of its quickest model, too. The 1987 GNX managed a 4.6-second bolt to 60 mph in tests by Car and Driver, and it also took the honor of being one of the automaker's rarest creations at just 547 units. You can check out all 10 in the gallery above.

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.

GM recalling 2013 Buick LaCrosse, Cadillac SRX over transmission software

The National Highway Traffic Safety Administration has issued recalls for the 2013 Buick LaCrosse and 2013 Cadillac SRX due to a problem with the software for the transmission controller. On about 27,000 SRX and LaCrosse models, the transmission could accidentally be shifted to Sport mode, which would reduce the amount of engine braking drivers experience.
NHTSA says this could increase the risk of a crash, but, fortunately, the required fix is simply an update to the software.
While we're on the subject of General Motors vehicle recalls, a small number (48) of compressed natural gas versions of the 2011 Chevrolet Express are also being recalled for a potential risk of fire or explosion. Yikes. Both official recall notices are posted below.
