When the Panamera arrives next year, 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 -- and price -- 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.
