Porsche sales are one thing that hasn't suffering in today's cloudy economic environment.

The company set a new record with 42,323 vehicles sold in the U.S. in 2013, a jump of 21 percent. Matthias Müller, the CEO of Porsche AG, attributes the growth in sales primarily to the wide range of attractive models, including the Macan.

The Boxster Series, which includes the new Cayman, and the new 918 Spyder, 911 GT3, 911 Turbo S and the "50 Years 911" exclusive model are expected to add to the excitement surrounding Porsche sales in 2014.

The breakdown of sales by model reveals some interesting information about consumer behavior. The Cayenne sport-utility vehicle was the top seller this year, selling more than 18,500 vehicles.

The 911 sports coupe, thought of as the foundation of Porsche's high-end image for over 50 years now, accounted for a quarter of the total sales (10,442). It outsold the lower-priced Boxster and Cayman cars, speaking to the fact that consumers are most interested in the expensive, luxury models.

The Panamera accounted for just over 12 percent of sales (5,421). The luxury four-door, front-engined model was unveiled in April 2009, and two years later the hybrid and diesel versions were launched. The intention of the Panamera was to be a more exciting alternative to traditional executive cars like the Audi A8 and Mercedes-Benz S-Class.

Boxster and Cayman sales had dropped steadily since the early 2000s until last year. In 2003, Boxster sales accounted for 21 percent of total sales with 6,432 vehicles. This dropped to 14 percent from 2006-08. The combined total for the two was 3,875 vehicles sold from 2009-11. This dropped again to 9.6 percent in 2012, with both models totaling 3,356 sales. In 2013, however, Boxster and Cayman sales more than doubled to 7,953 for 18.8 percent of total sales.

It seems that the Cayenne and 911 will continue to be the best-sellers for Porsche, which falls in line with what is happening in markets for a range of luxury products, be it designer fashion or private yachts. The most expensive models with the most upgrades available tend to outsell smaller, more affordable versions.

If this holds true over time, Porsche can expect to see continued sales growth and more interest in new, high-end models in the future and will continue to enjoy its reputation as the world's most prestigious automobile brand.
