The company has a huge international presence, selling vehicles in major countries across the world. It has more than 212,000 employees working in 396 facilities across six continents.

Some roads are open only to drivers who have passed special performance driving training. The saying goes that each mile driven on the grounds is the same as 5 miles in the real world.
