While Porsche may be facing multi-billion lawsuits over its failed takeover bid of Volkswagen AG in 2008, the company future is looking bright on the sales front.

Today, Porsche Cars North America [PCNA] announced 2011 year-to-date sales of 29,023 vehicles, an increase of 15 percent over 2010 when it delivered 25,320 units in the States.

“2011 represents a very positive step forward for Porsche and demonstrates the brand’s continued strength in the United States market,” said Detlev von Platen, PCNA’s President and CEO.

“We are confident we will build on this momentum moving forward into the new year with the launch of the 7th generation 911, a new Boxster and several other new products,” he added.

Much of Porsche’s sales momentum is attributed to the Cayenne SUV, of which 12,978 units were sold in 2011 compared to 8,343 examples in 2010, recording a 56 percent increase.

Even though the 911 will be replace by an all-new model this February, Porsche delivered 6,016 units of its classic sports car compared to 5,735 in 2010, representing an increase of 5 percent.

Porsche also saw total sales of its Approved Certified Pre-Owned (CPO) vehicles total rise from 7,298 units in 2010 to 8,323 last year.

On the other hand, the Panamera sports saloon and the soon-to-be replaced Boxster roadster and Cayman coupe duo saw their sales drop 11.1 percent and 10 percent respectively.
