Porsche has announced the Panamera has become their best-selling model in the United States.

In April, Americans bought 678 Panameras compared to 219 Boxsters, 135 Caymans, 389 911s, and 326 Cayennes. The latter is a bit of a surprise, considering the Cayenne is in the midst of its "lame duck" life-cycle related decline.

The company is quick to remind us the redesigned 2011 Cayenne will go on sale (in the U.S.) in July. While this will undoubtedly increase Cayenne sales, the entry-level Panamera / Panamera 4 will go on sale in June.

What model will win the sales crown? Only time will tell.
