The Ghost coupe, which will likely be badged as a Corniche, shares the same powertrain as the standard sedan. This means that under the lengthy hood is a 563-bhp twin-turbocharged 6.6-liter V-12 engine, coupled to an 8-speed automatic transmission. Rolls-Royce might opt to squeeze a few extra horsepower from the engine, if only to keep pace with the competition.  The car was spotted on the Nürburgring recently, demonstrating its sporting chops at the same time it was showing off it's impressive patrician nose. Expectations are that, when the new coupe is shown off for real at the Geneva Motor Show in March of next year, that nose will belong to the fastest production car to ever wear the Spirit of Ecstasy. 2013-Rolls-Royce-Phantom-Extended-Wheelbase-Emblem-Logo
