This is a specially revised Lexus LS600h which will be used at the wedding of Prince Albert II of Monaco to Charlene Wittstock on Saturday 2 July.
It is one of seven full hybrid LS 600hs which will be exclusively used to transport all members of the Royal Family throughout the occasion.
The car conversion was carried out by Carat Duchatelet, of Liège, Belgium. The company has among its customers more than 50 Heads of State and Royal families.
The car had to be completely un-built and stripped out of all its features and equipment to undergo the roof cut and the subsequent chassis modifications.
