"         The new Panamera sedan has been an incredibly expensive project for a company of Porsche&amp;#039;s relative small size. For all intents and purposes, the Panamera is a completely new car from the ground up. The chassis, body and \u2014 in the case of the Panamera 4S and Turbo \u2014 all-wheel-drive system share little with any other Porsche. The Cayenne-based V-8 is about the only piece that wasn&amp;#039;t designed from scratch.   Because of the amount of money invested, sources tell us Porsche is keen to get more of a return out of the project than what is expected from the Panamera alone. To help the cause, Porsche is considering a 928-like coupe version of the big 4-door to compete head-to-head with the likes of Bentley&amp;#039;s Continental GT, BMW&amp;#039;s M6, Maserati&amp;#039;s GranTurismo and Mercedes&amp;#039; AMG cars.   As with the Panamera, the coupe version (our source tells us a soft-top convertible is also possible, but absolutely not a retractable hardtop) will be powered by normally aspirated and turbocharged front-mounted 4.8-liter V-8 engines. Expect significantly more than 400 bhp from the base engine along with well over 500 bhp from the Turbo when and if the Panamera coupe goes on sale, which likely won&amp;#039;t be until at least 2013. Porsche&amp;#039;s 7-speed twin-clutch PDK will come stand\u00ADard. And unlike the old 928, we expect the coupe version of the Panamera to be available with all-wheel drive.
