Inside Trump's new car dubbed the 'Beast': £1.2m Cadillac has eight-inch thick doors, can survive a roadside bomb and has an an oxygen system in case of a chemical attack 

It is known as Cadillac One and 'The Beast' 

or, as President Trump now calls it, his personal limousine service.

These pictures show the brand new incarnation of the President's official vehicle undergoing final testing before it is delivered to the White House.

The sedan is longer than two large SUVs and, for the moment, remains in white and black camouflage designed to make it more difficult to identify new features aboard the vehicle.

The final version will be painted black and silver just like the current version, once it is given the final approval.

The £1.2 million car is part of a fleet of 12 which cost around £15 million and is arguably the safest vehicle in the world, as befits the President of the United States.

The Beast weighs eight tonnes and has eight-inch thick steel doors that weigh the same as those on a Boeing 757 - and are sealed to withstand biological and chemical attacks.
