Mercedes-Benz is number one...in terms of worldwide sales, that is.

For the fourth year in a row, Mercedes-Benz is the world's top selling luxury automaker, edging out its rivals BMW and Audi. So just how many new Mercedes-Benzes found a new home in 2019?

Excluding heavy-duty commercial vehicle sales, the three-pointed star shifted 2,339,562 cars and crossovers last year. In fact, global sales for Mercedes-Benz went up by 1.3 percent from 2018. While it sounds like a small number, that's still an additional 30,414 units.

Mercedes-Benz attributes this growth to record sales in key markets. The brand hit record sales in the U.S, their home market of Germany, and most significantly, China. The People's Republic is the world's biggest auto market and growth there will most definitely have a positive impact on sales. It remains to be Mercedes-Benz's biggest market too, with nearly 700,000 units sold in that country alone.

BMW may be number two but they also made great strides in 2019. The M Division, and Rolls-Royce posted double-digit growth last year, while the i electric division also showed an increase of sales as well. Mini did have a dip in sales, but overall sales for the BMW Group are still up by 2 percent for a total of approximately 2.1 million units worldwide.

As for Audi, they're still a fair way behind Mercedes-Benz and BMW at 1,845,550 sales in 2019. But while they didn't break two million units last year, Audi is poised to keep building up momentum. That's thanks to a host of all-new and facelifted cars and crossovers that were introduced within the last two years. All in all, Audi sales went up by 1.8 percent, a good year nonetheless.

What about the local luxury car stakes? We're still waiting for everyone to turn in their numbers, but the mid-year report showed that Mercedes-Benz and BMW are neck and neck. For now though, let's wait for the results to come out.
