Tesla Model S vs Porsche Taycan S Crash Test! Really SAFE? Is the marketing true?

The passenger compartment remained stable in the frontal impact. Readings from the passenger dummy indicated good protection of all body areas except the head. Analysis of the dummy kinematics showed that the airbag on the passenger side had 'bottomed out' i.e. there was insufficient inflation to prevent the head flattening the airbag and coming into contact with the facia, through the airbag material. Tesla investigated the issue and found an error in the airbag calibration software supplied by the vendor. Euro NCAP has been informed that this error has been corrected in all vehicles supplied to customers. Although the calculated injury parameters were not hazardous, protection of the passenger head was penalised and rated as adequate. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Tesla showed that a similar level of protection would be provided to occupants of different sizes and to those sat in different seating positions. In the side barrier test, the Model S scored maximum points with good protection of all body regions. In the more severe side pole test, dummy measurements of rib compressions indicated marginal protection of the chest. Protection against whiplash injury in the event of a rear-end collision was rated as good for the front and rear seats.

The Model S scored maximum points for its protection of the child dummies in the dynamic tests. Both dummies were seated in rearward-facing restraints and showed good protection in the frontal impact. In the side impact, both dummies were properly contained within the protective shells of their restraints, minimising the risk of head contact with parts of the vehicle interior. The front passenger airbag can be disabled through the user menu, allowing a rearward-facing restraint to be used in that seating position. However, the interface is not clear in all languages about the actions being taken to set the airbag status and the system was not rewarded. All of the restraints for which the car is designed could be properly installed and accommodated with the exception of the Group I universal restraint in the rear outboard seats. While the seat could be installed, the seat cushioning made engagement of the ISOFIX probes difficult. Integral child restraints are available as an optional third row in the Model S.

The passenger compartment of the Taycan remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. Porsche showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. In the full-width rigid barrier test, protection of all critical body areas was good or adequate for both occupants, with the exception of the rear passenger's chest, for which dummy readings of compression indicated a marginal level of protection. In the side barrier impact, protection of all critical body areas was good and the car scored full points in this tests. In the more severe side pole test, protection of the chest was adequate and that of other body areas was good. Tests on the front seats and head restraints demonstrated marginal protection against whiplash injuries in the event of a rear-end collision. A geometric assessment of the rear seats also indicated marginal whiplash protection. The standard-fit autonomous emergency braking (AEB) system performed well in tests of its functionality at the low speeds at which many whiplash injuries occur. However, the Taycan was not awarded the points for these tests as good dynamic performance in the front seats is a prerequisite for AEB scoring.

In the frontal offset test, protection of all critical body areas was good for both dummies except the neck of the 6 year dummy, protection of which was rated as marginal on the basis of tensile forces measured in the dummy. In the side barrier test, protection of all critical body areas was good and the Taycan scored maximum points in this part of the assessment. The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position. Clear information is provided to the driver regarding the status of the airbag and the system was rewarded. One universal child restraint could not be positioned stably in the rear centre seat. Otherwise, all of the restraint types for which the Taycan is designed could be properly installed and accommodated in the car.
