With a top speed of 171 miles per hour, the 2008 Porsche Cayenne Turbo has the ability to leave runways on fire when it barrels by. For Porsche to go from sport cars to sport SUVs and still have success is quite impressive. This diversified lineup has increased sales and opened up new markets for the industry’s smallest independent vehicle manufacturer. In fact, in 2004 (the first full year of sales for the Cayenne) it accounted for roughly half of Porsche’s sales; with more than 150,000 having been sold worldwide. Sonically and technically inventive, the trio of all-new Porsche SUVs -- Cayenne, Cayenne S and Cayenne Turbo -- offer great performance, comfort and social recognition. A Cayenne Hybrid will be coming out before the end of this decade.
