BMW won its luxury brand title back in 2014 after increasing December sales by 11 percent last month to knock off rival Mercedes-Benz.

The automaker said that sales were helped by the introduction of vehicles like the BMW 3 and 4 Series and X5 SUV, along with the right products that provide good value for the customer," according to a company release.

Daimler's Mercedes-Benz unit received a big sales push from the redesigned C-Class and GL-Class SUV in December, selling 34,009 vehicles in the month alone, according to Bloomberg.

During the same month, BMW sold 41,526 units, not including its MINI brand. The Munich-based automaker sold approximately 339,738 vehicles in the U.S. in 2014, or 9,347 more than Mercedes-Benz.

In 2013, Mercedes-Benz sold 312,534 luxury models, compared to BMW's 309,280, according to sales numbers posted on the automaker's website.

Mercedes almost doubled sales of its CLA-class vehicles to 27,365 units in 2014, and also doubled sales for its S-class cars to approximately 25,000 units. The CLA-class hurt C-class sales overall however, which dropped 15 percent to about 13,000 units, according to Mercedes.

BMW experienced low sales for some of its pricier vehicles as well. While sales for the 3- and 4-Series jumped 19 percent last year, sales for the 6- and 7-Series dropped 11.4 percent and 10.9 percent, respectively.
