Tesla: Model S fails emergency braking test

A 2015 Tesla Model S reportedly failed an emergency braking test conducted by ILNAS (Institut Luxembourgeois de la Normalisation, de l'Accréditation, de la Sécurité et qualité des produits et services) in Luxembourg.

According to a report by the Wort of Luxembourg, the Model S tested failed to engage the emergency braking system in time, which led to the car rear-ending a dummy vehicle. In a video posted on Wort's website, the Tesla vehicle is shown decelerating, but not avoiding the collision entirely, instead coming to a full stop right after the impact. The American manufacturer's vehicle was loaded with the latest software update of the Autopilot.

According to a comment by Tesla, communicated to Electrek today, the ILNAS refused to provide details of the procedure followed, but Tesla will continue to investigate the incident. The Tesla spokesperson also noted that the Model S used is registered as a rental car in Germany - built in 2015. Although the details of the procedure have not been officially published, the photographic evidence and relevant footage posted online sheds some light on how the testing occurred.

The Model S was tested alongside a brand new Volvo S90 (2018), which, according to the report by Wort, passed the test with flying colours - the Swedish manufacturer's flagship reportedly managed to come to a complete halt when driving up to speeds of 60km/h (37mph). What is interesting is that, a quick research on Volvo's City Safety system reveals that the new Volvo S90 is not actually capable of such behaviour - at least not exactly. As the relevant Volvo S90 manual reveals, the vehicle is capable of avoiding collisions at speed differences up to 50km/h (31mph), but can only mitigate collisions at higher speeds. It thus raises questions on ILNAS claim that the Volvo vehicle managed to avoid collision at a higher speed than the one officially quoted by the manufacturer. 

The reported failure of the Tesla vehicle is added to a tumultuous week for the California based manufacturer: the production goal of 5,000 Model 3 units / week was reached for the first time this week, but the company's Head of Engineering, Doug Field, decided to resign and Elon Musk accused a reporter of engaging in bribery


ILNAS is Luxembourg's standards body and represents Luxembourg in international standardization organizations, such as the ISO. It is a public service and operates under the authority of the Minister in charge of the Economy of Luxembourg.
