The National Transportation Safety Board says it's investigating an incident earlier this week in Florida in which a Tesla Model S was engulfed in flames after an apparent high-speed crash. Two teenagers were killed and a third seriously injured.
The NTSB said Wednesday it was dispatching a four-person team to Fort Lauderdale. The probe will focus on the emergency response to the post-crash fire in the electric vehicle's battery pack.
The NTSB said it did not believe the car's autonomous driving system was engaged at the time of the crash. Tesla said in a statement after the crash that while it had not retrieved data from the vehicle, "everything we have seen thus far indicates a very high-speed collision and that Autopilot was not engaged. Serious high-speed collisions can result in a fire, regardless of the type of car.”
It's the second time in the past two months that the NTSB has investigated a Tesla fire. A probe is under way into a fire in a Tesla Model X SUV that crashed March 23 on U.S. 101 in Mountain View. The company has reported that that vehicle's Autopilot system was engaged when the car smashed into a barrier wall.
Lithium-ion batteries like those used by Tesla can catch fire and burn rapidly in a crash, although Tesla has maintained its vehicles catch fire far less often than those powered by gasoline.
