Is there anything else to discuss this month besides the fact that By the Numbers has a new graphic? Since sometime in 2006, I've dutifully collected this monthly sales data and published it in table form for your perusal, and I've always accompanied the data and my analysis of it with that funny little graphic of a green car going up (or down) a red hill. I've no idea where I found it, probably a Google image search, and have resisted changing it for so long partly on account of laziness, but also an obstinate will to maintain consistency. That will, good people, has been broken, and for the better I think, based on the lovely new graphic you see above these words.

On to the numbers, which for the most part were pleasantly high across the industry. American brands lead the way with Cadillac posting a 46.97-percent surge in sales and Dodge a 37.43-percent jump. Lexus and Buick were also up over 30 percent in January.

Of the big brands selling close to or over 100,000 units per month, Toyota took top honors with a rise in sales of 26.05 percent, though not far behind was Ford with a 23.35-percent lift. Chrysler appeared in the teens at 17.56 percent, while Honda (12.74 percent) and Chevrolet (10.85 percent) each reported healthy increases, as well.

Nissan, however, showed a mere 1.76-percent rise in the raw number of vehicles it sold last month. When converted to the change in the Daily Average Sales rate, that number falls to -2.31 percent. Other surprises at the bottom of the list include Hyundai (2.39/-1.71 percent), Kia (2.21/-1.88 percent) and BMW (0.66/-3.37 percent), while Jeep and Mazda both sold fewer models last month than the year before no matter which column you look at.

The rest of the numbers are below, and you can view more from the past in our By the Numbers archive.



*Brands and companies are displayed in descending order according to their percentage change in volume sales. There were 25 selling days in January 2013 and 24 selling days in January 2012, so there is a difference between the change in monthly sales volume and the change in average daily sales rate (DSR) for each brand/company. Also, brands are combined and reported as companies only if their sales figures are released jointly.
