Porsche is working hard on a four door saloon to compete with Maserati, BMW, Mercedes and Audi. This four door GT is planned for 2009. It will come bearing two weighty things: a 4.8-liter 520-hp twin turbo V8, and a $197,000 price tag. Beneath that model will be the normally aspirated V8. And to even get into the Panamera party, you’ll need $127,000, which will get you a measly 3.6-liter V6, but that doesn’t arrive until 2010. More pics after the jump.
