A book released last summer indicates that car fanatic King Juan Carlos I of Spain has 65 employees tending to his 71 vehicles.  Make that 72 vehicles.

Photographs obtained by Diariomotor show the King's latest acquisition, the Audi RS6.  The car joins a fleet that includes a 1959 Rolls Royce Phantom IV, a Maybach, and his first car ever, a classic Mini.  The King previously owned a Porsche 959 that he crashed on an icy road in the Pyrenees at the end of 1990.

The Royal's Audi RS6 was likely given to the monarch by the German car manufacturer.  It is painted in black, with a blacked-out Audi logo, and dark graphite five-spoke wheels.  Under the hood, it has a 5.0-liter TFSI engine producing 572 horsepower and up to 480 ft-lb of torque.  The engine of the RS6 is mated to a six-speed Tiptronic transmission, with power going to four wheels.  Audi's saloon is capable of a 0-100 km/h sprint of 4.5 seconds, and has an electronically-limited top speed of either 250 km/h or 280 km/h.

Monarchical upgrades to the car include front-mounted emergency lights, a special license plate only availble to royalty, and flag-holders above the front wheels.
