In case you'd forgotten about Porsche's upcoming sedan, the automaker decided to take the wraps off its all-new 2010 Porsche Panamera Gran Turismo (as the car is now officially known) in this teaser photograph.

Well, sort of.  While the rest of Porsche's portfolio (Boxster, Cayman, 911, and Cayenne) are on full display, we're privy to only the Panamera's nose.  We're more interested in seeing the car's aft section, as early sketches and spy photographs suggest the car will display a bustleback profile.

We'll see the car in its entirety in the spring of 2009 (and possibly in print advertisements beginning October 20), but until then, Porsche will release updates on the car via the Panamera Online Magazine, available at www.porsche.com/panamera.
