The FIA has released the results of an analysis of Grosjean's accident

The FIA ​​has released the results of an analysis of the accident in which Romain Grosjean managed to escape from a burning car after an accident in the first lap of the Bahrain GP with which he ended his F1 career earlier than planned.

After hitting the metal barriers along the track, Grosjean was trapped in a burning car that was halved due to a strong impact, but the safety cell remained intact. The Frenchman lost control during contact with Daniil Kvyat at a speed of 241 km / h and hit the barriers at a speed of 192 km / h, which resulted in a deceleration that is 67 times bigger than the acceleration of gravity.

The FIA ​​announced after the accident that it would launch a detailed investigation into the incident to improve safety standards, and three months after the accident, they released the results of the investigation.

"The car suffered extensive damage during the impact, including the separation of the powertrain assembly from the safety cell," the statement said. "The fuel filler flap on the left side of the chassis has detached, and the fuel supply has been torn off the fuel tank's safety bubble, creating ways for fuel to escape from the tank."

“Driver safety equipment, which includes a helmet, HANS, seat belts, safety cell, seat, headrest, and Halo cockpit frontal protection, did the job according to specifications and protected the driver’s space, controlling the forces acting on the driver during the impact.

” "The battery of the High Voltage Recovery System (ERS) was significantly damaged, and some parts of the ERS battery remained with the drive unit while some remained connected to the chassis." "The fire appeared in the final moments of the impact on the barriers, starting from the back of the safety cell, and progressed towards the driver as it grew."

FIA investigation

The FIA ​​has announced that they will consider the following elements to improve security: -revision of fuel bubble installation design in all FIA single-seater categories
-recommendations for fuel safety bubble installation
-the new FIA standard for fuel safety bubbles
-revision of the rules for the design of fuel safety bubble connections and inspection covers
-fuel type-approval must include compatibility of bladder material and specific fuel The FIA ​​has also confirmed that it will conduct an analysis of the rules for the geometry of the front of the safety cell and -additional load tests of the area, as well as a revision of the steering wheel mounting requirements after Grossen's left leg got- stuck in the cockpit due to damage.
