The Citan Tourer is identical to the Mercedes-Benz T-Class in terms of safety performance.  Accordingly, the tests performed on the T-Class and the electric EQT are used for this rating of the Citan Tourer and e-Citan Tourer.

The passenger compartment remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger but a small penalty was incurred for structures in the dashboard on the driver’s side which might lead to a reduced level of protection to those of different sizes or sitting in a different position.  Protection of the passenger dummy was good for all critical body areas.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the vehicle would be a benign impact partner in a frontal collision. In the full width rigid-barrier impact, protection of all critical body areas was good for the driver and at least adequate for the rear seat passenger.  In the side barrier test, protection of all critical body areas was good and maximum points were scored. In the more severe side pole impact, protection was good or adequate. Control of excursion (the extent to which a body is thrown to the other side of the vehicle when it is hit from the far side) was found to be adequate. The T-Class has a counter-measure to mitigate against occupant to occupant injuries in such impacts and this performed well in Euro NCAP's test. Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric analysis of the rear seats also indicated good whiplash protection.   The Citan Tourer has an advanced eCall system which alerts the emergency services in the event of a crash.   The car is not equipped a system which applies the brakes after an impact to avoid secondary collisions.

In the frontal offset test, protection of all critical body areas was good or adequate, for both the 6 and 10 year dummy.  In the side barrier impact, protection of all body areas was good and maximum points were scored.  The front passenger airbag is automatically disabled when a rearward-facing child restraint is put in that seating position. Tests showed that the system worked robustly and the system was rewarded. All of the child restraint types for which the car is designed could be properly installed and accommodated.

The protection offered by the bonnet to the head of a struck pedestrian was largely good or adequate, but with some areas which were marginal or weak performance, and poor results were recorded on the stiff windscreen pillars.  The bumper provided good protection to pedestrians’ legs at all test locations but protection of the pelvis was mixed.  The autonomous emergency braking (AEB) system can detect vulnerable road users, as well as other vehicles.  In tests of its response to pedestrians, the system performance was adequate while its response to cyclists was rated as good.

The AEB system performed well in tests of its response to other vehicles, with impacts avoided or mitigated in most test scenarios.  A seatbelt reminder system is standard and the car is equipped with Driver Attention Warning, which monitors steering inputs and issues a warning when a pattern characteristic of drowsy or impaired driving is detected.  A camera-based speed limit system detects the local limit and provides the information to the driver, allowing the limiter to be set accordingly.  If the car is drifting out of lane, a camera-based system gently corrects the vehicle’s path.  The system also intervenes in some more critical situations, to avoid road departure for example.
