Mazda North American Operations, almost alone among North American carsellers, saw its sales decrease in July versus July of 2011. Year-to-date sales, however, were higher at the more than 700 Mazda dealers in the United States and Mexico through July than during the same period last year.

July sales in the United States were 7 percent lower (at 19,318 units) than July of 2011, while Mazda Motor de Mexico saw sales decrease 14 percent (to 1,942 vehicles).

However, the company reached July 31 with year-to-date sales for North America up 13.9 percent (163,115 vehicles) over last year's.

Sales for every model but the Miata were down. The Miata experienced a sales increase of 3.7 percent over July of last year, with 590 units sold versus the previous July's 569.

In announcing last month's sales figures, Mazda noted that vehicles with its SkyActiv fuel-efficiency technology have accounted for 60 percent of its US sales since February. It attributes this to the addition of the CX-5 compact crossover SUV to the lineup of vehicles available with the technology.

The CX-5 replaces the Mazda Tribute, which ceased production after the 2011 model year, and which sold all of two leftovers off of dealer lots last month.

Models that experienced decreases from last July but year-to-date increases are the Mazda 2 (15.6-percent decrease; 29.9-percent increase), Mazda 3 (2.8-percent decrease; 12.7-percent increase), and Mazda 6 (49.3-percent decrease; 47.2-percent increase)

Models to see decreases on both scales were the Mazda 5 (16.2 percent for the month; 38.8 percent year-to-date), the CX-7 (89.7 percent for the month; 41.4 percent for the year), and the CX-9 (25 percent; 28 percent).
