Rolls-Royce has released a new video showing the product manager Philip Harnett drive the new luxury Wraith coupe on country roads.

The Wraith made its public debut back in March at the Geneva Motor Show and is essentially a Ghost Coupe.Powered by a 624bhp V12 engine mated to 8-speed automatic ZF transmission it is the most powerful and fastest Rolls ever with 0-60 mph taking just 4.4 seconds.There is also a clever system called Satellite Aided Transmission which uses GPS data to preselect the correct gear for the type of terrain up ahead that Philip also talks about in the video below.The Wraith convertible has also been confirmed and is expected to arrive in late 2014 or in early 2015.
