The Porsche Panamera has outdone its brothers to be the bestselling Porsche in the United States. In April alone, 678 Panameras were purchased in the United States as compared to the 219 Boxsters, 135 Caymans, 389 911s, and 326 Cayennes sold. 2011 will however see a redesigned Porsche Cayenne, which have added sales too. The Panamera, available in the US since October 2009, is a four seat Gran Tourismo.
The Cayenne has seen a fall in sales, a life-cycle related decline, because of which a newer version is under the hammer being developed. The new version, the Cayenne S Hybrid will be a green vehicle consuming just 8.2 liters of gasoline for every 100 km. Looks like these two SUVs by Porsche are neck deep in an annual sales competition.
