Jessi Lang recently spent a week in the 2010 Porsche Panamera 4S. This sport sedan is nothing short of amazing. The all-wheel-drive Panamera 4S with its normally aspirated, 32-valve DOHC, 4.8-liter V8 makes 400-horsepower but due to the highly efficient PDK transmission that 400 hp feels a lot more like 500. Jessi road tests and reviews the new Panamera which compares to BMWs might M5 and the Mercedes-Benz AMG models. Stay tuned to the end of the video for more of Jessi’s bloopers!
