In a post about the ten longest limousines in the world, we find this:
The last limousine is actually the longest super stretch limousine in the world. Total length is 100 feet (more than 30 meters). It has 26 tires, room for a lot of passengers, a heated Jacuzzi, sun deck, swimming pool, a few beds and… a helipad!

re: turning,
LimoQuoter.com says the middle is hinged to help it make turns. There's also 2 driver's cabins for easier backing-up.
