To ensure that the vehicle is able to move safely, quickly and comfortably through traffic, despite the increased weight resulting from the protective measures, both the suspension and brakes, as well as the electronic control and restraint systems of the E-Class, have been adapted for the E-Guard. In braking tests, for example, it has been demonstrated that the additional protective components have no effect on performance: the vehicle comes to a standstill with precision. The extremely high level of general safety which is characteristic of Mercedes-Benz has also been tested and ensured in special crash tests. As a result the special protection vehicle is also able to fulfil all of the requirements in the event of a collision. Furthermore, additional harshness tests, such as fatigue loading on simulated rough roads, brake tests in Alpine passes, climate tests in extreme temperatures and corrosion endurance tests, all help to ensure the hallmark reliability of Mercedes-Benz and the high level of comfort of the E-Class Saloon models.
