The sales numbers are in for September and again the Chevrolet Camaro has outsold the refreshed 2010 Ford Mustang and the Dodge Challenger.  This makes the fourth straight month the Camaro has beaten out the Mustang who by all means has been the leader in this category for a long time.  No time in history has the Camaro outsold the Mustang for two straight months let alone four.

Sales of the 2010 Chevrolet Camaro for September of 2009 were 7,961 compared to 8,680 from the previous month showing a 8% decrease in month-to-month sales.  However Mustang had a decrease of almost 22% in month-to-month sales.  Comparing the numbers shows a Camaro decrease of 719 while the Mustang sold 1372 less month-to-month.  Year to date Camaro sales are 39,151.

The Ford Mustang sold 4,917 and the Dodge Challenger sold 1,778 for September.

In August, Ford sold 6,289 units of the 2010 Mustang, while General Motors clocked sales of the 2010 Chevy Camaro at 8,680 — a sizable difference of 2,391 vehicles. This is the third straight month that the Camaro has beaten the Mustang on the sales floor: in June the Camaro rang up 1,958 more unit sales, and in July, 427.

When it comes to Detroit’s Big Three, Ford is the suppose to be the belle of the ball these days: the company never accepted bailout dough from the U.S. government, and as a result, Ford’s brand and its sales are both doing pretty well. However, one of the company’s flagship models — the Ford Mustang — comtinues to lose ground to one of its primary competitors, the Chevrolet Camaro.

In some ways, this isn’t surprising. The Camaro has been generally well received in the press, and although our own reviewers have both models tied at a score of 8.4, the Camaro outperforms the Ford in some ways (e.g. base horespower, fuel economy).  The fact that the Camaro was front-and-center of the American public for some time thanks to the Transformers‘ Bumblebee didn’t hurt, either.

On the other hand, a new set of ratings put out by Consumer Reports gives the 2010 Ford Mustang slightly better marks than the 2010 Camaro, not to mention the Dodge Challenger. In the study, Mustang received a “very good” road test rating of 78 points, while the Camaro also earned a “very good”, but with a lower score of 71 points. The Challenger was scored at 53 points, which put it in the “good” category.
