A special armored version of the Mercedes-Benz S-Class has been produced, known as the S-Guard. This model is specifically designed for high-risk security environments. Customers which may require such a vehicle include diplomats and celebrities. Special features of the latest model, produced in 2006, include the capability to withstand military-grade small arms fire and certain explosive devices, a self-sealing fuel tank, and a special alarm system.[18]

The S-Guard is widely used at the diplomatic level to protect world leaders. Ninety governments worldwide are known to use the S-Guard for transport of government leaders and dignitaries.[19] Commercial buyers may opt for the High-Protection S-Guard, with the ability to withstand small arms fire; for those at risk of assassination and terrorist attacks, the Highest-Protection Guard model is designed to withstand military rifles and high-velocity ammunition. The S-Guard is built on a special production line at the S-Class facility in Sindelfingen, Germany, with specific S-Guard enhancements integrated at multiple stages throughout the production process.[19]
