The all new 2010 Porsche Panamera is finally ready to make its North American Debut this August. After a year of hype and rumors about everything from its sheet metal to its powerplant, Americans will now be able to see for themselves what Porsches new 4 door sedan is all about. The Panamera's styling is somewhat subjective due to the fact that is almost resembles a station wagon or a hatch back over a 4 door sedan. Its design seems to be very purposeful though, and its obvious that the classic 911 shape had a lot of influence in the Panamera's shape. Power comes from a trusted line of engines in Porsches naturally aspirated and turbo V8's, both displacing 4.8 liters. The non-turbo's output is 400 horsepower while the turbo is putting out a healthy 500. Expect to see an "S" variant added to the turbo lineup at some point down the road, utilizing the Cayenne Turbo S's 550 horsepower engine. Regardless of the styling, this sports sedan is sure to please from the drivers seat. European models have impressed critics already. The turbo model is putting up 4 second 0-60 mph times, and a claimed top speed of 188 mph. When BMW's new M5 comes out in about a year, there will surely be fireworks when the two sedans go head to head.
