|RENAULT'S ACCIDENT ANALYSIS DEPARTMENT
The Accident Analysis department at Renault has more than 500 employees. This section receives a weekly spreadsheet from the judiciary containing all reported traffic accidents in the whole of France. The more severe accidents (with serious injuries/fatalities), in which a Renault is involved, are chosen from this list. Subsequently, a team sets out to analyse the accident and accident data is collected.
The first step is to put back all loosened components. Then, photos of the vehicle are taken from 8 different angles (the front and rear end - both sides - from every corner).

Then, over 200 points of the vehicle involved are then compared with an undamaged vehicle of the same type. All obtained information is stored in a database. Another one of the team’s tasks is taking inventory of the injuries of those involved. For this, additional photos are also taken of particularities such as lipstick on an airbag, impact marks and damage to seat belts. From the traces of the lipstick and the injuries of the victim, it was apparent that the airbag was activated at the right moment and height (see below).

Other particularities: impact marks. Renault Mégane hit from the rear. The driver died from his wounds.

Partly due to the body length of the victim (1.95 meters) and the impact, the victim had severe head and neck trauma with fatal consequences. Had the victim been smaller, he/she would likely have survived the accident.
Through these analyses, Renault now possesses a database in which more than 18,000 vehicle types and 32,000 victims have been recorded. This is how Renault has a good picture of which accidents happen most often and which damage leads to which trauma. But it also knows that there are differences in traumas because of the age, weight and length of the victim. The position of the victim in the vehicle also leads to differences. These days at the Accident Analysis department, a lot of extra attention is paid to accidents in which an electric vehicle was involved. Electric vehicles are reinforced in different areas than ‘normal’ vehicles and are much heavier. What is noticeable is that a different accident mechanism has been created by this.
Analysts have concluded the following:
IMPORTANT! It was also apparent that the service/emergency deactivation switch in electric vehicles is almost never loosened. In a number of the investigated Renault Zoes, this was mainly because this emergency switch is in front of the passenger seat and that is the very place where the first responders tend to sit during a rescue scenario. People don’t want to remove the first responders to be able to reach the emergency switch.

ATTENTION! Another conclusion reached by the analysts is that the airbags aren’t always activated. Even if there was sufficient impact to activate an airbag. Besides that, airbags were virtually never activated in a collision from the rear.

The vehicle did not recognize the accident, or else the airbags would have been activated. There is a chance that the drive is still activated in this situation.
