Nissan North America said it reached the highest U.S. market share level in company history during February.

The automaker discovered its U.S. market penetration climbed to 9.3 percent last month. The new record comes after Nissan says it gained 0.4 percentage points throughout 2010 to vault it to one of the three fastest-growing OEMs in the U.S.

Last month, the company determined it sold 92,370 vehicles versus 70,189 units a year earlier, an increase of 31.6 percent. Sales at its Nissan division spiked 31.8 percent for the month and also set a new February record. Meanwhile, officials determined sales of Infiniti vehicles rose 29.9 percent over the prior year and marked the 13th consecutive month of double-digit sales improvement.

Beyond the raw numbers, the company offered more Nissan highlights:

—The brand moved 83,226 units to compile a market share of 8.4 percent — a record for any month.

—It sold 11,427 Rogues, a figure 86.0 percent higher than last year, setting a new all-time volume and segment share record.

—The brand moved 12,599 Sentras, a total came in 62.2 percent above last year’s figure, leading to a segment share of 10.5 percent — the best since September 1996.

—The company sold 5,318 Maximas, establishing a new February segment share record at 11.3 percent.

—The brand moved 3,527 Frontiers, an amount 39.3 percent higher versus last year and the best February segment share since 1985.

—It sold 1,806 Armadas, a sum that was up 49.1 percent versus last year and tied its best segment share ever at 10.2 percent.

Officials also shared several Infiniti February sales performances:

—The nameplate posted 9,144 sales during the month, a total that was up 29.9 percent over the prior year for a share of total luxury of 8.7 percent — a February record.

—The brand moved 4,044 G sedans, an amount 50.6 percent higher than last year, setting a new all-time share record of 11.6 percent.

—The company sold 902 QX56s, helping the unit establish a new February share record of 9.7 percent.

To ensure consistency in global sales reporting, Nissan reiterated that it calculates monthly variances on a straight-percentage basis, unadjusted for the number of selling days. The company pointed out both February 2011 and February 2010 had 24 selling days.

“Nissan continues to grow in the U.S. market through rigorous improvements in our marketing effectiveness, entry into new product segments like commercial vehicles and strengthening our performance in existing segments,” stated Carlos Tavares, chairman of Nissan Americas.

“As we bring on stream more new products like the NV commercial van line, the all-new Nissan Quest and other future products we intend for our presence in the market to grow further,” Tavares stated.
