This ultra-luxury sedan is the Queen Elizabeth II Maybach 57S. It was created by custom car company A Kahn Design to celebrate the 60th anniversary of the Queen's ascension to the thrown. Some eagle-eyed gearheads will probably wonder why a Maybach was chosen, seeing as how the brand was killed off last year and all.
That's a good question and one that there isn't an immediate answer for. However, a special Maybach was created to celebrate the recent royal wedding, and it sported the same "4 HRH" (for his royal highness) that the Queen Elizabeth II Maybach 57s does. The royal one-off sports 22-inch wheels and a livery befitting a queen. It's set to pop up around the British capital to celebrate the queen's 60th year on the throne.
