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.

Buick mulling more powerful Encore; diesel too

Looking to set itself apart in the mid-luxury segment, Buick is looking to introduce a diesel engine somewhere in its US lineup. And according to Edmunds, the two best chances of a diesel Buick rest with the Encore and Verano.
In both our First Drive and Review of the 2013 Encore, our chief complaint about the compact crossover was the the lack of power from the 138-horsepower turbo engine. Edmunds says that the recently introduced 1.6-liter four-cylinder engine (with both gas and diesel variants) from the Encore's overseas cousin, the Opel Mokka, could make its way into the Encore delivering the much-needed boost in power.
Then there's the Verano. As a close relative to the Chevy Cruze, which just added a diesel engine for 2014, the article speculates that a Verano Diesel might actually be the more "probably candidate" if and when Buick decides to add a diesel model to its portfolio. Either way, offering such an engine in one of its products could be a great way for Buick to differentiate itself from Cadillac and possibly even attract buyers from Volkswagen, Audi and Mercedes-Benz looking for a luxurious, fuel-efficient vehicle.

Buick Encore takes a hit of Mokka to tackle Dakar

There are many vehicles we'd consider taking racing. Even on a cross-country rally as punishing as the Dakar. But a Buick Encore? That's not one that would enter our motorsports-based consciousness. Yet it's basically what General Motors is entering in the South American rally raid this year, and you're looking at it.
Unveiled at the Moscow Motor Show, this rally machine is based on (or at least billed as) an Opel Mokka - the name that GM's European brand applies to the vehicle Americans know as the Encore, Buick's subcompact crossover. Only it's obviously been extensively modified. It's got a ten-inch raised suspension, a 137-gallon fuel tank, carbon-fiber bodywork and... hold on, we're sure we're missing something here. Oh, right: a 6.2-liter V8 kicking out 340 horsepower and 487 pound-feet of torque to all four wheels through a six-speed sequential gearbox.
In other words, this is not the same Encore (or Mokka) you can pick up at your local Buick, Opel or Vauxhall dealership. It's not even close. It's not even recognizable as such, really. It was unveiled alongside a more sedate Opel Mokka Moscow Edition and a slew of other local debuts for the Opel brand that you can read more about in the (translated and original) Russian press release below.
